What is Commercial Roofing?

When you walk into a sprawling warehouse, shop at a retail center, or work in a modern office building, you’re protected by sophisticated roofing systems that operate on an entirely different scale than residential homes. Commercial roofing represents a specialized field that encompasses far more than simple weather protection—it’s about safeguarding business operations, managing energy costs, and maintaining critical infrastructure that keeps commerce running smoothly.

Understanding what commercial roofing entails is essential if you’re responsible for a commercial property. From the materials used to the installation process, maintenance requirements, and long-term costs, commercial roofing systems differ dramatically from residential roofs in ways that directly impact your bottom line and operational continuity.

Definition of Commercial Roofing

Commercial roofing covers the installation, repair, and maintenance of roofing systems on commercial buildings, warehouses, factories, retail stores, and office complexes. These sophisticated systems protect commercial properties typically exceeding 10,000 square feet and must handle significantly heavier loads than residential roofs ever encounter.

Unlike residential roofs, which primarily focus on aesthetic appeal and basic weather protection, commercial roofs must support substantial HVAC equipment, industrial machinery, and frequent foot traffic from maintenance personnel. A typical commercial building might have multiple rooftop units weighing thousands of pounds, solar panel installations, cooling towers, and regular access for maintenance teams—demands that residential roofs aren’t designed to handle.

The primary purpose extends beyond protecting the structure itself. These roofing systems safeguard business operations, inventory valued at potentially millions of dollars, employees, and customers from weather elements such as rain, snow, hail, and wind. When a commercial roof fails, the consequences ripple through every aspect of business operations, making reliability and durability paramount concerns.

Commercial properties encompass a vast range of building types, from small retail buildings covering 5,000 square feet to massive distribution centers spanning over 500,000 square feet. Each requires a carefully engineered roofing system designed to meet specific performance criteria, building codes, and operational requirements that vary significantly based on the building’s intended use.

How Commercial Roofing Differs from Residential Roofing

The differences between commercial and residential roofing systems extend far beyond simple size considerations, encompassing fundamental design philosophies, structural requirements, and performance expectations that reflect the distinct needs of business versus residential environments.

Design and Structure

Commercial roofs are typically flat or low-slope, with pitches less than 3:12, compared to residential roofs, which feature steep pitches ranging from 4:12 to 12:12. This fundamental difference stems from functional requirements—commercial buildings prioritize maximizing interior space utilization and accommodating rooftop equipment, while residential buildings emphasize aesthetic appeal and efficient water runoff.

Commercial structures span much larger areas, often covering 50,000 to 500,000 square feet, compared to residential roofs, which average 1,500 to 3,000 square feet. This massive scale creates unique engineering challenges, particularly regarding thermal expansion and contraction across vast roof surfaces, structural load distribution, and effective water management systems.

Flat commercial roofs require sophisticated drainage systems, including internal drains, scuppers, and specialized gutters, to prevent water pooling—a critical concern, as standing water can compromise membrane integrity and create structural problems. These drainage systems must handle substantial water volumes during intense storms while preventing backup that could flood interior spaces.

Commercial roofs must support rooftop equipment weighing thousands of pounds, including chillers, cooling towers, exhaust fans, and increasingly common solar panel arrays. This equipment placement requires careful structural analysis and reinforcement, along with accessible maintenance pathways that don’t compromise the roofing system’s waterproof integrity.

Materials Used

Commercial roofs utilize fundamentally different materials designed for durability, performance, and large-scale application rather than aesthetic appeal. Single-ply membranes like TPO (Thermoplastic Polyolefin), PVC (Polyvinyl Chloride), and EPDM (Ethylene Propylene Diene Monomer) dominate commercial applications due to their ability to cover large areas seamlessly and provide long-term weather resistance.

Modified bitumen systems and built-up roofing (BUR) with multiple asphalt and reinforcement layers remain common for commercial applications where extreme durability and puncture resistance are priorities. These multi-layer systems provide redundancy that single-ply systems cannot match, making them ideal for high-traffic commercial environments.

Metal roofing systems, including standing seam steel and aluminum panels, are designed for large spans and can support substantial loads while providing decades of service life. These systems often incorporate specialized coatings and insulation configurations optimized for energy efficiency in large buildings.

In contrast, residential roofs primarily use asphalt shingles, clay tiles, slate, or cedar shakes chosen for aesthetic appeal and weather protection rather than load-bearing capacity or large-scale performance. While some overlap exists in materials like metal roofing, the specifications, installation methods, and performance requirements differ substantially between residential and commercial applications.

Types of Commercial Roofing Systems

Commercial roofing encompasses several distinct system types, each engineered to address specific performance requirements, building characteristics, and operational needs. Understanding these systems helps property owners make informed decisions about new installations, replacements, and maintenance strategies.

Single-Ply Membrane Roofing

Single-ply membranes are the most widely used commercial roofing materials for flat roofs, offering efficient installation, proven performance, and energy-efficiency benefits that align with modern building requirements and environmental regulations.

TPO roofing has gained significant market share due to its energy efficiency benefits, featuring white reflective surfaces that can reduce cooling costs by 15-20% in hot climates. These thermoplastic membranes are heat-welded at seams, creating monolithic waterproof barriers that resist wind uplift, chemicals, and UV degradation. TPO systems typically provide a 20-25-year service life with proper maintenance.

PVC roofing membranes offer superior chemical resistance, making them ideal for restaurants, food processing facilities, and industrial properties that are exposed to grease or chemicals. These membranes resist many oils, greases, and chemicals that can degrade other roofing materials, while offering excellent fire resistance and energy efficiency. PVC systems provide exceptional durability in challenging environments.

EPDM roofing delivers outstanding weather resistance and flexibility, maintaining performance characteristics across extreme temperature ranges. Black EPDM absorbs heat, which can benefit heating costs in cold climates but may increase cooling loads in warmer regions. White EPDM formulations address energy efficiency concerns while maintaining the material’s proven durability. EPDM systems can last 25-30 years with proper maintenance.

Installation of single-ply membranes involves mechanically fastening, fully adhering, or ballasting membranes to create watertight seals. Mechanical attachment uses fasteners through insulation into the roof deck, while fully adhered systems use specialized adhesives for complete bonding. Ballasted systems place loose stone over membranes, providing wind resistance through weight rather than attachment.

Built-Up and Modified Bitumen Roofing

Built-up roofing (BUR) systems use alternating layers of bitumen and reinforcement fabric, creating robust multi-ply membranes topped with gravel or mineral cap sheets. These time-tested systems provide excellent redundancy—if one layer develops issues, underlying layers continue protecting the building while repairs are planned and executed.

The installation process involves applying hot asphalt or coal tar between reinforcing plies, building up waterproof membranes in multiple layers. Surface treatments typically include gravel embedment for UV protection and fire resistance, though smooth-surfaced systems with mineral cap sheets are also common. BUR systems excel in high-traffic areas and can withstand heavy equipment installation better than single-ply alternatives.

Modified bitumen systems combine traditional asphalt technology with modern polymer science, incorporating rubber or plastic modifiers that enhance flexibility and durability. SBS (styrene-butadiene-styrene) modified systems remain flexible at low temperatures, while APP (atactic polypropylene) modified systems provide enhanced high-temperature performance and UV resistance.

These systems can be installed using torch application, hot mopping, cold adhesives, or self-adhering methods, depending on specific product formulations and project requirements. Multi-ply configurations typically involve a base sheet adhered to the substrate, followed by one or more intermediate plies, and finished with a mineral-surfaced cap sheet.

Both BUR and modified bitumen systems typically provide service lives of 20-25 years, depending on climate conditions, maintenance quality, and installation workmanship. These systems cost $6-12 per square foot installed, reflecting their labor-intensive installation requirements and robust material specifications.

Metal Commercial Roofing

Metal roofing systems, particularly standing seam systems, offer exceptional longevity and performance for commercial applications. Standing seam systems use interlocking panels that run continuously from eave to ridge, with raised seams that accommodate thermal movement while concealing all fasteners beneath the seams.

Galvanized steel represents the most common metal roofing material, providing excellent strength-to-weight ratios and corrosion resistance when properly coated. Aluminum systems offer superior corrosion resistance and lighter weight, making them ideal for coastal environments or buildings with limited structural capacity. Both materials can support significant snow loads and equipment installations while maintaining structural integrity.

Cool metal roofing incorporates specialized reflective coatings that can reduce energy costs by up to 25% compared to traditional roofing materials. These coatings reflect solar radiation while maintaining high thermal emittance, keeping roof surfaces cooler and reducing air conditioning demands in commercial buildings.

Metal roofing systems provide 40-60 year lifespans with minimal maintenance requirements, making them attractive for long-term ownership scenarios despite higher initial costs. The systems excel in areas with severe weather conditions, providing excellent wind resistance, fire protection, and hail damage resistance.

Installation requires specialized expertise in metal fabrication, thermal movement accommodation, and weather sealing details. Proper installation ensures seams remain watertight throughout decades of thermal cycling while allowing for the substantial movement that occurs across large metal roof surfaces.

Commercial Roofing Installation and Maintenance

Commercial roofing projects involve complex coordination, specialized equipment, and strict adherence to safety protocols that distinguish them from residential installations. The scale, complexity, and performance requirements of commercial properties demand professional expertise and comprehensive planning throughout the project lifecycle.

Installation Process

Commercial roof installations require specialized equipment, including cranes, hot air welders, material hoists, and safety systems designed for large-scale operations. Projects typically require 1-4 weeks, depending on building size, weather conditions, and system complexity, with detailed scheduling to minimize business disruption during installation.

The installation process begins with thorough substrate preparation, including structural assessments, removal of the existing roof when necessary, and deck repairs or modifications to meet current building codes. Insulation installation follows, with commercial buildings typically requiring R-25 to R-30 insulation values in most climate zones to meet energy efficiency requirements.

Installation must comply with stringent building codes, fire ratings, and wind uplift requirements specific to commercial structures. These requirements often exceed residential standards significantly, particularly regarding fire resistance classifications and wind uplift ratings that can exceed 90 pounds per square foot in high-wind zones.

Quality control throughout installation involves multiple inspections, testing of membrane seams, verification of fastener patterns, and documentation of all system components. Many commercial roofing projects require third-party inspections and testing to validate warranty compliance and building code conformance.

Weather coordination becomes critical for commercial installations due to project scale and exposure duration. Contractors must have contingency plans for precipitation protection, wind limitations for crane operations, and temperature requirements for membrane installations and adhesive applications.

Maintenance Requirements

Commercial roofs require professional inspections twice annually—typically in spring and fall—to identify potential issues before they develop into costly problems. These comprehensive inspections examine membrane surfaces, seams, flashings, drainage systems, and rooftop equipment interfaces for signs of deterioration or damage.

Regular maintenance includes cleaning debris from drains and gutters, inspecting membrane seams for separation, checking flashing around penetrations, and ensuring rooftop equipment hasn’t compromised membrane integrity through vibration or improper installation practices. Drainage system maintenance is particularly critical, as clogged drains can cause ponding water that accelerates membrane aging and creates structural concerns.

Preventive maintenance programs can extend roof service life by 50% while preventing approximately 85% of potential leaks when properly implemented. These programs include scheduled inspections, minor repairs, resealing of flashings, and proactive replacement of deteriorating components before failure occurs.

Emergency repairs must be addressed within 24-48 hours to prevent interior damage and business disruption. Commercial roofing contractors maintain emergency response capabilities, including temporary waterproofing systems that can protect interior spaces while permanent repairs are planned and executed.

Documentation of all maintenance activities, repairs, and inspections is essential for warranty compliance and asset management planning. Many commercial property owners maintain detailed roof condition databases that track performance trends, maintenance costs, and replacement timing for budgeting purposes.

Why Specialized Commercial Roofers Are Necessary

The complexity and specialized nature of commercial roofing systems demand contractors with specific training, experience, and capabilities that extend far beyond general construction or residential roofing expertise. These requirements reflect the critical nature of commercial roofing systems and their impact on business operations.

Commercial roofers require extensive training in fall protection systems, OSHA safety protocols, and safe working procedures around industrial equipment and occupied buildings. Working on commercial properties often involves complex safety coordination with ongoing business operations, requiring contractors who understand how to minimize disruption while maintaining strict safety standards.

Understanding building codes, fire ratings, and structural load requirements for commercial applications requires specialized knowledge that general contractors typically don’t possess. Commercial buildings must meet stringent performance standards for wind uplift resistance, fire classification, and energy efficiency that demand expertise in system design and installation methods.

Commercial roofing contractors carry substantially higher insurance coverage—typically $2-5 million in liability protection—due to project complexity, property values, and potential business interruption costs. This insurance reflects the higher risks associated with commercial work and provides property owners with protection against potential failures in installations or materials.

Experience with specialized techniques like membrane welding, modified bitumen installation, and complex flashing details is essential for quality workmanship. These skills require extensive training and practice that residential roofers typically don’t develop, as the techniques and materials are specific to commercial applications.

Commercial contractors also maintain relationships with specialized manufacturers and suppliers, ensuring access to commercial-grade materials and technical support throughout project execution. These relationships often include manufacturer training certifications that validate installer qualifications for warranty compliance.

Commercial Roofing Costs and Considerations

Commercial roofing represents a significant capital investment that requires careful financial planning and analysis of long-term costs versus benefits. Understanding the factors that influence costs helps property owners make informed decisions about system selection, contractor choice, and timing of replacement projects.

Commercial roofing costs range, depending on materials, building height, accessibility, and project complexity. This broad range reflects the substantial differences between basic single-ply installations and complex multi-story projects with extensive rooftop equipment and challenging access requirements.

TPO and EPDM roofing systems are popular choices for cost-conscious property owners who need reliable performance without premium pricing. These systems provide good value through proven durability, energy efficiency benefits, and relatively straightforward maintenance requirements.

Metal roofing systems have a higher material costs and specialized installation requirements. However, metal systems often provide superior long-term value through extended service lives, minimal maintenance requirements, and excellent energy efficiency, which can offset higher initial costs.

Several factors significantly impact project costs beyond basic material selection. Roof accessibility affects labor costs and equipment requirements, with high-rise buildings or complex roof configurations requiring specialized equipment and additional safety measures. Existing roof removal adds to project costs when complete tear-offs are necessary.

Insulation upgrades often accompany commercial roof replacements, particularly when buildings need to meet current energy codes. Insulation costs range depending on thickness and material selection, but energy savings often justify these investments through reduced utility costs over the roof’s service life.

Commercial roofing projects represent major investments ranging from $50,000 for small retail buildings to over $500,000 for large distribution centers or office complexes. This investment scale requires careful contractor selection, thorough contract review, and comprehensive warranty evaluation to protect the property owner’s interests.

Financing considerations often influence project timing and scope, with many property owners coordinating roof replacements with other building improvements to maximize efficiency and minimize business disruption. Lifecycle cost analysis becomes critical when comparing system options, as seemingly expensive systems may provide superior value over 20-30 year analysis periods.

Selecting a professional roofing contractor with commercial expertise, proper licensing, insurance coverage, and manufacturer certifications is essential to protecting this substantial investment. Quality installation directly impacts system performance, longevity, and warranty compliance, making contractor selection as important as material choice for long-term success.

When evaluating commercial roofing options for your property, consider working with experienced commercial roofing contractors who can provide detailed proposals, lifecycle cost analysis, and comprehensive warranty coverage. The complexity and investment level of commercial roofing systems make professional expertise essential for achieving optimal results that protect your business operations for decades to come.

Standing Seam Metal Roof - Everything You Need to Know

Wondering if a standing seam metal roofing system is the best roofing system for your property? Knowing how a standing seam metal roof is built, its advantages, disadvantages, and how long it lasts will help you determine whether it's right or not for your project.

atlantacommercialroofingcontractors.com gathered essential information about what a standing seam metal roof is, how one is built, how it differs from a metal roof, and its long lifespan.

What Is a Standing Seam Metal Roof

A standing seam metal roof is a roofing system consisting of metal panels joined together with raised seams. The panels are typically made from steel, aluminum, or copper and come in various colors and finishes.

"Standing seam" refers to the raised seams that run vertically along the length of each metal panel. These seams are raised above the panel surface level and are typically joined together using an interlocking mechanism. When properly installed, this creates a watertight seal that prevents water from penetrating the roof.

Standing seam metal roofing systems are popular because they are extremely durable, long-lasting, and require minimal maintenance. These roofs are energy-efficient, reflecting the sun's rays and helping keep a building’s interior cool in the summer. Additionally, they are fire-resistant and can withstand sustained high winds and other extreme weather conditions.

Components of a Standing Seam Metal Roof

A typical standing seam metal roof consists of multiple components, including the following:

• Metal Panels - These are a roof’s main structural element, typically made from steel, aluminum, or copper.
• Roof Underlayment - This protective layer is installed beneath the metal panels providing additional weather protection and preventing moisture from entering the building.
• Roof Deck - This is the roof’s foundation and is typically made from wood, metal, or concrete (depending on the structure’s construction).
• Flashing - This is typically a thin metal strip installed at the edges, penetrations, and roof seams to prevent water from penetrating the roof and causing damage or decay.
• Fasteners - These are the screws or clips used to attach the metal panels to the roof deck. They are designed to allow for the panel’s thermal movement (expansion and contraction) and prevent damage to the roof.
• Ridge Caps - These metal pieces covering the roof’s ridge (the roof’s uppermost part) provide additional weather protection.
• Snow Guards - These are devices installed on the roof to prevent snow and ice from sliding off and causing damage or injury.

Each component plays a crucial role in a standing seam metal roof’s performance and durability. Proper installation and regular maintenance of these components are essential to ensure the roofing system’s longevity and effectiveness.

Standing Seam or Metal Roof - What’s the Difference?

The terms "standing seam" and "metal roof" are frequently used interchangeably, but there is a distinct difference between them. Consider the following:

A metal roof is a roofing system made from metal materials like steel, aluminum, or copper. It can be constructed in various styles, including standing seam, corrugated, and shingle.

However, a standing seam roof is a specific metal roof type featuring raised seams that run vertically along the panels. The seams are raised above the panel surface and are typically joined using a locking mechanism, creating a watertight seal helping prevent water from penetrating the roof.

While standing seam roofs are a type of metal roof, not all metal roofs are standing seam. Other metal roof types may have different profiles, textures, and colors than standing seam roofs.

The principal difference between a standing seam roof and a metal roof is that a “standing seam” roof is a specific metal roof type featuring raised seams, while a “metal roof” refers to any roofing system made from metal components.

Standing Seam Metal Roof Pros and Cons

Standing seam metal roofs offer several advantages and disadvantages compared to other roofing systems. Consider the following pros and cons of standing seam metal roofs:

Advantages:

• Durability - Standing seam metal roofs are incredibly durable, potentially lasting 50 years or more with proper maintenance.
• Weather-Resistant - Metal roofs resist weather like high winds, hail, and heavy rain.
• Energy-Efficient - Standing seam metal roofs are reflective, helping to reduce cooling costs in warmer climates.
• Low Maintenance - Metal roofing systems require minimal maintenance and are relatively easy to clean.
• Aesthetically Pleasing - Standing seam metal roofs offer a sleek, modern look complementing various architectural styles (potentially increasing a property’s curb appeal).

Disadvantages:

• Installation Cost - Standing seam metal roofs can be significantly more expensive than other roofing systems, like asphalt shingles.
• Noise - Rain, hail, and other precipitation can be extremely noisy on metal roofs, which can be a significant concern and deciding factor for some property owners.
• Installation - Standing seam metal roof professional installation requires specialized equipment and expertise, which may add to the roof’s installation cost.
• Expansion & Contraction - Metal roofs expand and contract with temperature changes, which may cause fasteners to loosen or back out over time, potentially leading to leaks.
• Potential for Dents - Metal roofs are prone to denting when hit by large hail or other projectiles.

Standing seam metal roofs offer multiple benefits and are a popular choice for homeowners and commercial property owners wanting a durable, energy-efficient, and low-maintenance roofing solution. However, they may not be the ideal option for every roofing situation, and it's essential to weigh the advantages and disadvantages carefully before making a decision.

Flat Roof Drainage Systems Explained

Avoid structural damage to your building due to your flat roof drainage system failing to do its job. Knowing how flat roofing systems drain will help you determine a course of action when yours stops working.

atlantacommercialroofingcontractors.com gathered the following information about flat roof drainage systems, their pros, and their cons.

How Do Flat Roofs Drain?

Flat roofs don’t benefit from sloped roofing systems and gravity to assist them with water removal. They require a drainage system to help remove and channel the water. There are three flat roof drainage systems that work in perfect harmony with flat roofs, and each one has its pros and cons:

Scuppers

Scuppers are found on many commercial and residential flat roofs. Scupper drains are equally effective and important as other drain systems. Special attention should be given to their location and installation on flat roofs.

What is a scupper? Scuppers are drain openings placed in low-lying areas on the side of a roof for water drainage. A scupper can be installed through a side wall or a parapet wall.

Scupper Pros:

• No leaf or debris build-up, everything washes away from or blows off the roof
• Water shoots away from the building instead of down the side
• Can add architectural/curb appeal to the roofline with custom-built or molded scuppers
• Minimal cost
• Easy to almost no maintenance required
• No clogging issues if the scupper is large or wide enough

Scupper Cons:

• If downspouts are installed below your scuppers, they will need to be checked and cleaned regularly since they can easily clog.
• Scuppers may not be as effective in severe downpours and seasonal snowmelt.

Scuppers can be easily installed and maintained by your roofing company.

Gutters

The majority of roofing systems are installed with a gutter system for water drainage. This is the most popular drainage system with the goal of draining water from the roof, moving it to the ground, and ejecting it away from the structure’s foundation.

Don’t be misled to think that gutters are not effective for a flat roofing system. Though flat roofs are nearly level in comparison with pitched roofing systems, they are not entirely flat.

They do possess very low slopes that help them drain water. Gutters can collect the water that naturally falls off your roof into an open gutter system. They then channel the water off and away from the home or commercial building. Gutter systems are by far the most cost-effective drainage solution for flat roofs, but they require regular cleanings and periodic maintenance for the best results.

Gutter Pros:

• Inexpensive and common, gutters are the easiest drainage system to find, customize, and install.
• This system helps divert water from inconveniently pouring off the roof in heavier rains, protecting walls, doorways, and windows.
• Gutters, with their downspouts, work wonders in keeping water away from the structure, preventing severe water damage.

Gutter Cons:

• Gutters typically pull away from fascia boards with time.
• Gutters are highly susceptible to debilitating damage from ice, heavy debris, and severe weather.

Gutter drainage systems should be maintained and cleaned multiple times per year (especially prior to and after the rainy season in your region).

Interior Drains

This type of drainage system is often found on the roofs of large buildings, but it may also be used for residential homes. These drain systems are typically built into the structure before the roofing system is installed on it. In this respect, they are like a sink or shower drain. They use an interior system of pipes, are typically found below the roof, and carry water away from the home’s foundation. These drains are commonly located in the center of the roof.

Interior Drain Pros:

• The pipe system is protected by the roof and walls of the building. This minimizes risks of pipe bursts, failure, cracking, or freezing.
• This flat roof drainage system effectively protects your walls and foundation from suffering any severe water damage.
• This drain system is somewhat customizable and can easily boost your curb appeal with custom fittings.

Interior Drain Cons:

• Interior drain installation is the costliest of all flat roof drainage systems.
• While these drains are less susceptible to damage or clogging, you will need to have a professional roofing technician or a certified plumber make any repairs to damage that may occur.
• You’ll need to remain cautious since debris can easily clog up the system. Installing strainers/filters and routinely checking the system can help prevent blockages. If ignored, you may have to deal with standing water on your roof.

The Right Drainage System for Your Flat Roof

Any of these systems can effectively divert water from your flat roof, provided it is correctly installed and properly maintained. It’s important to strongly consider each drainage system’s strengths and weaknesses before making your decision, including cost, durability, and maintenance requirements. When in doubt, consult your roofer and consider your building type and location to help you come up with the best drainage system for your flat roofing system.

Flat Roof Drainage

In this article, you discovered three of the ways flat roofing systems efficiently drain and expel rainwater and snowmelt.

Knowing how your roofing system drains water away can help you determine when your roof may need maintenance, cleaning, and even repairs.

Ignoring your roofing system’s drains can lead to severe structural problems and costly repairs when they stop functioning correctly.

Asbestos Roofing Removal

Avoid dangerous exposure to carcinogens when your asbestos roofing system needs replacing. Knowing what to look for, then how to test and safely remove a residential or commercial roofing system that contains asbestos will offer an enormous peace of mind, and reduce your risk or liability.

atlantacommercialroofingcontractors.com gathered the following information about what to do when your roofing system containing asbestos gets damaged or fails, the dangers of asbestos exposure, and resources to help you protect your personal and/or workplace safety.

How Do I Know If My Roofing System Contains Asbestos

The most reliable way to tell if some material contains asbestos is to have a certified asbestos inspector collect samples of suspect asbestos-containing roofing materials and submit them to an analytical laboratory for analysis. Remember, all layers and parts of a roof should be sampled. Asbestos may be in one layer or part and not in another.

Tip: The older your roofing system is, the more likely for asbestos to be present.

What is Asbestos

Asbestos is made up of groups of mineral fibers naturally occurring in rocks and soil. Known for its strength, durability, and resistance to fire and water, asbestos was used commonly in various construction applications for the greater part of the 20th century. Asbestos is a thermal and acoustic insulator. It was used to make combustible objects flame retardant. Asbestos fibers are flexible and elastic, long-lasting, and can be spun or woven.

Asbestos Testing

Before starting any demolition, restoration, or repair work on material suspect of being treated or contaminated with asbestos, testing will help you determine how to proceed. Testing can be accomplished by:

• Using a commercially available asbestos testing kit
• Hire a professional, certified asbestos inspector

Tip: The National Voluntary Laboratory Accreditation Program (NVLAP) has an online tool to help you locate an accredited local testing laboratory; access the tool for a local testing lab

What Roofing Materials May Contain Asbestos?

Before public awareness of asbestos hazards and Federal regulations/restrictions, asbestos was added during the production of roofing materials to strengthen them, increase their durability, and provide some insulation and fireproofing. The use of asbestos in roofing has declined rapidly since the early 1980s.

The following common roofing products may contain asbestos:

• Adhesives
• Coatings
• Decking
• Felts
• Shingles (asphalt and concrete)
• Underlayment
• Vapor retardants
• Flashing
• Mastics
• Sealants

Why Remove Asbestos Roofing

Several decades ago, asbestos came with a number of construction “conveniences” before awareness of its dangers; it is now accompanied by feelings of concern and terror, as People exposed to the toxin having developed lung cancer, malignant mesothelioma, asbestosis, and other lung diseases and issues.

Why Is Asbestos Bad for My Health

The risk of asbestos depends on the type of product in which it has been incorporated and its state of degradation. Asbestos can be hazardous to human health because microscopic particles persist long after being introduced and can be inhaled when released into the air. Asbestos exposure is linked to higher rates of cancer and incurable asbestos-related illnesses.

Asbestos is released into the air in the form of tiny fibers and lodges itself in the lungs. Its indestructible nature makes it difficult or impossible to expel. Lethal diseases, like asbestosis, lung cancer, or mesothelioma (pleural cancer) can develop. The most harmful effects of asbestos and all its symptoms on the human body sometimes do not manifest for 20 years or more after exposure. Asbestos is one of the leading occupational causes of death.

How Can I Be Exposed to Asbestos

Asbestos fibers may be released into the air by the damage or disturbance of asbestos-containing material during product use, demolition work, building or home maintenance, repair, and remodeling. In general, exposure may occur only when the asbestos-containing material is disturbed or damaged in some way that releases particles and fibers into the air.

Adverse Health Effects from Asbestos Exposure

Exposure to asbestos increases your risk of developing terminal lung disease. That risk is exacerbated by smoking. In general, the greater the exposure to asbestos, the greater the chance of developing harmful health effects.

Asbestos-related medical conditions may be challenging to identify. Healthcare providers usually identify the possibility of asbestos exposure and related health conditions like lung disease by thoroughly evaluating one’s background. This includes looking at the person’s medical, work, cultural, and environmental history.

If a doctor suspects an asbestos-related condition, he or she can use multiple tools to help make a more accurate or pinpointed diagnosis. Some of these tools may be a physical examination, chest x-ray, and pulmonary function exams. Your doctor may also refer you to a specialist who treats diseases caused by asbestos.

Three of the significant health effects associated with asbestos exposure are:

• Lung cancer
• Mesothelioma, a rare form of cancer that is found in the thin lining of the lung, chest, the Abdomen, and heart
• Asbestosis, a severe progressive, long-term, non-cancer disease of the lungs

Note: Asbestos treatment specialists may include surgeons, oncologists, and other experts who specialize in treating pleural or peritoneal mesothelioma.

Asbestos Safety Resources

The following federal resources can help you further understand and adhere to accepted asbestos safety protocols:

What Is a Soffit – Why You Need It

A soffit is a critical component to prevent decay and eventual roof failure due to excess moisture accumulating in your attic. Discover what else your soffit does to help your roofing system meet its intended life expectancy.

atlantacommercialroofingcontractors.com gathered the following information about what a soffit is, its purpose, and why it is essential to your roofing system’s success.

What Is a Soffit?

When a sloped roof descends from the peak to the exterior walls of a structure, the roof will overhang the structure by 1 to 2 feet. Where you have tiles, shingles, or metal roofing on the topside, the soffit is the component underneath the overhang that protects the rafters, attic space, and roof substrate or decking from excess moisture, severe weather infiltration, potential mold growth and helps your roofing system last for the duration of its intended lifespan.

What Is The Difference Between Soffits and Fascia?

Soffits and fascia are installed together, forming a barrier between external elements and the attic space created by your sloping roofing system. Looking at a structure at street level, you may say the trim around the foot of the roof looks well-done. This “trim” is the fascia. With the soffit underneath the overhang and the fascia closing the gap between the soffit and the roof, the barrier, as mentioned earlier, is formed. These roofing components:

• Deter bee, hornet, and other insect infestations
• Stop wildlife (squirrels, raccoons, cats, etc.) from nesting in your attic
• Prevent water (wind-driven rain) from getting in your attic
• Keep your attic ventilated, preventing a buildup of moist/humid air that could lead to mold, mildew, and rotting problems
• Prevent premature aging of your roofing system

Soffits and fascia, when well-installed, can add to the visual “completeness” of the structure. Thus, adding curb appeal and potentially increasing the property’s overall value.

Note: Gutter systems installed around the foot of a sloped roofing system are typically affixed to the fascia. This is done in a manner that guides water runoff away from the roofing system, doorways, windows, and other vulnerable areas.

Soffit and Fascia Materials

To complement the construction of your home or type of roofing system, you can find soffit panels and fascia boards made from many different materials and finished in a wide variety of colors and textures.

Soffits and fascia are typically made from materials like:

Aluminum – Lasts 20+ years with colors and texture baked in to prevent fading.
Wood – Depending on the wood and maintenance, lasts 5 to 15 years.
UPVC (Unplasticised Polyvinyl Chloride) – Lasts 10 to 20 years and comes in multiple colors and textures but may fade or become brittle over time.
Vinyl – Similar to uPVC, lasts 10 to 20 years, is available in multiple colors and textures, and can become faded and/or brittle over time.
Steel – Lasts 25+ years with multiple colors and textures that resist fading.
Fibre Cement Board – Lasts 30+ years when properly installed and will never peel, chip, or rot.

Note: As with all roofing materials, the durability of the above-mentioned fluctuates with the quality, thoroughness, and frequency of your maintenance program.

Watch this video to see soffit and fascia trim installation.

Soffit and Fascia Installation and Repair Costs

Generally speaking, you will rarely need to replace all of your soffits and/or fascia. This will usually occur only when your roofing system is replaced.

In cases of roof replacement, soffit and fascia installation (labor and materials) will likely be included in your overall estimate or bid. You can ask for these as detailed line items in your estimate.

Soffit and/or fascia installation or repair will run in the $5 to $25 per linear foot range.

Note: Supply and demand will significantly impact the prices of materials considered commodities (wood materials).

Why Your Home Needs Soffits

In this article, you discovered what soffits are, what they do, and how they contribute to the success and longevity of your roofing system.

Keeping your soffits well-maintained allows them to properly ventilate your home’s attic while keeping moisture, severe weather, and destructive animal or insect infestations from taking years off the life of your roofing system.

Allowing your soffits to deteriorate or go without proper maintenance will lead to severe weather events, animals, insects, and humidity causing sere and costly damage to your roofing system and building structure.

Pros and Cons of Solar Panels for Commercial Buildings

Avoid paying expensive and erratic electric bills for the operation of your commercial building. Knowing the benefits of installing solar panels on your building will help you make informed decisions when it’s time to switch to solar.

atlantacommercialroofingcontractors.com gathered information on the pros and cons of installing solar panels on your commercial building and answers some frequently asked questions.

Solar Panels for Commercial Buildings

Your commercial building’s flat or sloped roof could be equipped with solar panels, transforming that space into a revenue saving “powerhouse.” Here are the pros of installing solar panels on your commercial building:

Solar Panels Help Your Business Save Money – While installing and setting up solar panels can be quite expensive, these costs are quickly offset by incurring dramatically reduced electricity costs and maintenance fees.

How Much Will Solar Power Reduce My Electric Bill – According to energysage.com commercial property owners can reduce their electricity bill by nearly 90% after installing solar panels.

Converting Your Building to Solar Brings Immediate Marketing Benefits – Installing solar panels on your building allows you to include “green company” in your marketing strategy and branding. As more countries encourage their populations to be less dependent on fossil fuels, your solar panels will make your business a part of a global movement.

Immediately Increase Your Property Value – Once you install solar panels on your commercial building (or in a solar panel garden), your property value instantly increases.

Solar panel capacity is measured in kilowatts, and each kilowatt can be valued in the thousands of dollars. Depending on the capacity of your solar system, your commercial property value may significantly increase. These values vary from state to state.

Installing Solar Panels Unlocks Access to Financial Benefits – The cost of switching to solar energy has dramatically decreased over the past decade and continues to fall as the market expands. Installation and equipment costs can also be offset by state and federal tax credits, rebates, and incentives.

Find policies and incentives by state at dsireusa.org and learn more about federal tax credits at energystar.gov/about/federal_tax_credits/solar_energy_systems

Billing Tenants for Their Energy Usage – If your commercial building has tenants, you can use virtual net metering (VNM) to generate extra revenue by recording the amount of solar energy they use and billing them accordingly.

Solar Panel Garden – In cases where your roof (flat or sloped) is too small or cannot support the extra load, solar panels can be installed in a field, parking lot, or other ground space. These ground-level installations are referred to as solar panel gardens.

Be aware that additional weight / roof load can be problematic and must be considered, read What is Your Commercial Roof Load and Why You Need to Know to determine if adding a solar panel garden is feasible.

Further Energy Savings – If your solar panels produce more energy than your building uses, that excess energy can be stored in batteries or fed back into the power grid. When excess energy is fed back to the power grid, your utility bill receives a credit calculated by the number of kilowatt-hours you gave back.

How Long Do Commercial Solar Panels Last – Commercial solar panels generally have a lifespan of 25 to 30 years. Even after this time, the panels do not stop producing energy. They produce significantly less energy than they did in their prime.

Commercial Solar Panel Installation Cons

While there are numerous advantages to installing solar panels, there are some potential disadvantages, which include:

How Much Do Commercial Solar Panels Cost – While your initial investment can be recovered within a five year period or less, solar panel installation is relatively expensive.

Before incentives and/or rebates, a commercial solar panel system installation can range in cost from $50,000 (25kW) to $200,000 (100kW) and $500,000 (250kW). These costs vary depending on material quality and installation labor.

Note: When installing a solar panel system on an existing structure, the electrical system will have to be reconfigured. In some cases, your roof may need to be upgraded, reinforced, or replaced to support the system.

Weather Systems – Solar energy can still be collected on cloudy or rainy days. However, solar system efficiency (dependent on sunlight) is dramatically reduced during these times.

Space Requirement – The more energy you want to produce, the more solar panels you will have to install. If the number of solar panels you need exceeds your roof’s size or load capacity, you may have to split the system between your roof and a solar panel garden.

Location Obstructions – Your system may not reach its intended capacity if your location is surrounded by tall trees or buildings.

Before installing a solar panel system, you should carefully consider the system’s pros and cons, have a technician perform a full review of your building, electricity requirements, and look for any obstacles that may render your investment a poor one.

Rooftop Solar Panels

In this article, you discovered significant advantages and disadvantages of installing solar panels on your commercial building’s roof.

Installing a solar power system can benefit your company’s image, reduce your dependency on natural resources, and save significant amounts of money over time.

Your reluctance to convert to solar power will result in your company’s complete dependence on your local power grid and the ever more expensive energy it provides.

Commercial Roof Inspection Checklist

Prevent roof failure, business interruption or a forced closure of your commercial property. Knowing how to inspect your roof will help you detect issues before they can interrupt operation or cause property damage.

atlantacommercialroofingcontractors.com gathered information on how to inspect your commercial roof, what to look for, and what actions to take when potential problems are detected.

Commercial Roof Inspection

Regular roof inspections, maintenance, and cleaning can minimize costly emergency roof repairs and significantly extend the life of your commercial roof. Commercial roofs should be inspected at least twice a year (late winter and early fall). If your commercial property has been subjected to high winds, severe storms, tornadoes, hail storms, or hurricanes, it is of the utmost urgency to inspect your roof and/or contract a roofer to inspect it for you.

The following are the primary things to look for when inspecting your roof. Print this roof inspection checklist, then mark the center box with a checkmark for “good” or an X for “needs attention or repair”:

1	Dirt and debris on roof or in drains/gutters		Clear debris with a leaf blower or power washer
2	Visible weather or impact damage		Document damage with photos and/or video
3	Pooling water (ponding) or water stains		Clear any obstructions from drains
4	Flashing		Note damaged or improperly installed sections
5	Penetrations, skylights, and vents		Note damages in the seal around the protrusion
6	Equipment anchoring		Correct any loosening or damaged anchors
7	Vegetation growth		Remove vegetation and note any damages
8	Mold and mildew growth		Remove and treat to prevent regrowth
9	Signs of vandalism		Document damages and report to authorities
10	Color fading or chalking		Call a professional roofer to evaluate the roof
11	Alligatoring or shrinkage		Call a professional roofer for repairs
12	Damaged seams or seals		Call a professional roofer for repairs
13	Animal infestation or damage		Call animal control then a roofer for repairs
14	Sagging or blistering		Call a professional roofer for repairs
15	Corrosion of metal components		Call a professional roofer for repairs
16	Damage from foot traffic		Limit foot traffic and contact a roofer for repairs
17	Firmness/stability		This may indicate a failing deck/support system. Have the roof professionally inspected
18	Downspouts		Clean or replace if clogged or damaged
19	Signs of leaks on external walls		Inspect the edges of the roof
20	Signs of leaks on internal walls and/or ceiling		These indicate the general area of a problem in the roofing system

Note: Repairing damages on your own may void the warranties covering both workmanship and materials. You can avoid such problems by purchasing a commercial roofing maintenance program from a trusted commercial roofing company.

Tip: The notes you take from multiple roof inspections should be shared with your professional roofer. Your notes may provide valuable insight into the issues you are experiencing.

Commercial Flat Roof Inspections

Commercial flat roofs may be composed of TPO, EPDM, Modified Bitumen, or Built-up (BUR) roofing. These roofing systems should be inspected a minimum of twice a year (late winter and early fall). These inspections will help catch developing damages from summer heat and winter freezes.

These roofing systems should also be inspected after significant or severe weather. Strong, sustained wind and heavy rain can exacerbate even the most innocuously appearing damages or defects. Pay special attention to the following:

• Membrane wear
• Stretching
• Ponding
• Punctures

Commercial flat roof systems can last for decades with proper installation and continuous care.

Tip: While rare, leaks in a BUR system may be challenging to locate. It is highly recommended to bring in a professional roofer to identify and repair such leaks quickly.

Commercial Metal Roof Inspections

Among the various roofing systems, a commercial metal roof may have the longest lifespan. However, without proper maintenance, these roofing systems can quickly develop serious problems. Watch for the following:

• Corrosion
• Damaged Panels
• Damaged fasteners or washer seals

While extremely durable, metal roofing systems still require periodic inspections and occasional repairs.

Commercial Sloped Roof Inspections

Commercial sloped roofing systems may be composed of slate, metal, tiles, or asphalt shingles. Like other roofing systems, sloped roofs can wear out over time or suffer significant damages from severe weather. For shingled roofs, consider calling a roofer when:

• Shingles lose grain
• Shingles start curling

When extensive wear and tear become evident on asphalt shingles, the roofing system may be nearing the end of its lifespan. For tile or slate roofs, pay attention to:

• Chips and cracks
• Missing tiles

Tile and slate roofing systems can be hazardous when cracks occur, or other problems arise. Leave these inspections or repairs to a professional roofing company.

Built-up Roofing System (BUR) Explained

Don’t invest your resources in an inadequate roofing system for your commercial property. Uncovering the benefits and properties of a built-up roofing system can help you make informed decisions when installing a new roof or replacing your existing roofing system.

atlantacommercialroofingcontractors.com gathered the most helpful information about built-up roofing, its installation process, warranty, associated costs, frequently asked questions, and potential problems with built-up roofing systems.

Built-up Roofing – Production Process & Properties

Built-up roofing systems, referred to as BUR, have been in use in the U.S. for over a century. This roofing system is also known as a “tar and gravel” roof. BUR systems are typically composed of alternating layers of bitumen and reinforcing materials that create a membrane.

This roofing system gains its waterproofing and durability from its layered structure, consisting of a “built-up” or layered combination of components, including:

1. Substrate or Decking
2. Roof Insulation
3. Roofing Asphalt
4. Venting Base Sheet (Cover Board) with Roofing Asphalt
5. Ply Sheet with Roofing Asphalt
6. Slag or Gravel in Asphalt or a Modified Bitumen Cap

Note: When a modified bitumen membrane is used to cap a BUR system, this combination is referred to as a “hybrid” system.

Roofing asphalt (bitumen) commonly used in BUR systems includes:

Asphalt – Asphalt (a petroleum product refined from crude oil) requires heating before application with a mop or spreader

Coal Tar – Coal tar (derived from the distillation of coal) also requires heating before application with a mop or spreader

Cold-Applied Adhesives – These adhesives are solvent-based asphalts that don’t require heating prior to application

Surfacings used on BUR systems may be (or a combination of):

Aggregate – Gravel, slag, crushed stone, and/or mineral granules are common aggregates

Cap Sheets – Commonly made with glass-fiber or mineral surfacing

Asphalt – Hot Asphalt spread or mopped over the entire surface

Alternative Coatings – Aluminum and elastomeric coatings are commonly applied as surfacing for BUR systems

Benefits of Built-up Roofing

In use for over a century in the U.S., properly installed BUR systems provide the following benefits:

• Well-installed, a BUR system can last more than 30 years
• Provides excellent waterproofing protection
• Creates a continuous sealed surface
• Seams are very well sealed (in some cases, many times over)
• Provides exceptional UV protection
• Once installed, the system is extremely low-maintenance
• Excellent impact resistance
• Excellent fire resistance

Along with these benefits is traction. Often overlooked, if your roof has foot traffic, a BUR system may be ideal due to gravel providing an excellent grip. This becomes evident during severe weather.

Built-up Roofing Installation and Warranty

The installation of your built-up roofing system, when properly installed, is a moderately fast and non-intrusive process.

A built-up roofing system can be installed using hot asphalt or cold adhesives. A standard built-up roof system is a multiple layered system applied in such a way that creates a seamless roof. The following can influence the end result of the roofing system’s installation:

• Proper roof slope for efficient draining
• Correct installation and fastening of insulation
• Correct application of cold adhesives when used in place of hot asphalt
• Proper placement and overlapping of material
• Drip edge seamlessly connected around the perimeter of the roof

In addition to high-quality installation, a warranty is valuable when the installation or components of your roof fail. There are two types of warranties to consider when installing or replacing this or any other roofing system:

Contractor’s Warranty – This warranty covers the workmanship and installation of your roofing system by the contractor. The contractor guarantees their work for a set period (3, 5, 10-year period, etc.), or for the lifetime of the roofing system. A contractor’s warranty should include the following:

• A list of all covered items
• Actions or events that may void the warranty
• When/If the warranty expires

The above installation and warranty information underscore the absolute necessity to thoroughly vet contractors before starting a roofing installation or replacement.

Note: There is no established industry standard for the duration of a contractor’s workmanship warranty.

Manufacturer’s Warranty – This warranty covers defects in the roofing material used in your roofing system. Once installed, your contractor should provide you with manufacturer’s warranty certificates.

An example of material failure would be premature alligatoring (small cracks in the roofing surface from shrinkage). Unless it is determined to result from poor or improper installation, a claim can be leveraged against the manufacturer’s warranty.

Built-up Roofing Cost

Collecting estimates for a roofing system can be a tedious experience. There is often a significant disparity from one quote to the next, which reinforces the necessity to collect at least three bids from three reputable roofing contractors.

Prices for installing a built-up roof system may vary with the size/complexity of the roof, time of year, material brand and quality, method of installation, and the amount of labor required taken into consideration. You can expect to see pricing in the following ranges:

Tear-off – Unless your new roof is installed over your current roof, the old one will be removed.

This process can range between $100 and $200 per square (1 square = 100 square feet).

Tip: If this cost gets bundled in material and installation pricing. Request that it be detailed separately in your estimate(s).

BUR Material – will fall between $100 and $175 per square

BUR Installation (Labor) – can range from $300 to $525 per square

Maintenance Contract – Commercial roofing maintenance program prices vary from contractor to contractor

Using the price ranges above, you can expect to see bids, including tear-off, material, and installation for a 1,000 square foot roof between $5,000 and $9,000.

Consumer Tip: In the roofing industry, installations are typically more expensive in late spring and summer months. If possible, schedule your installation for the off-season (early spring and fall).

Disclaimer: The above pricing is in no way intended to represent actual bid values and only serves as an estimated market price range.

Built-up Roofing Problems

With new materials, installation methods, and technology, BUR systems are becoming less popular. That said, a built-up roofing system may still be the best option for your commercial building. Before making any decision, consider the following potential problems sometimes associated with a BUR system:

• High wind may cause rocks or gravel to be blown off the roof (potentially damaging nearby structures or persons)
• While leaks are easily repaired, finding them may be a laborious and costly process
• This roofing system is heavy in comparison to others. Your commercial roof load should be verified before installing a BUR system
• BUR installation is slower than that of other less complex roofing systems. Increased labor costs can make BUR systems more expensive

You must do your research to see if the pros outweigh the cons of this or any other roofing system. You can check out and compare the alternative options to a built-up roof system to find something better suited for your property’s needs.

People Also Ask
