By following these steps, you can effectively address the issues we’ve identified.

Mending Leaks

When dealing with a leaking flat roof, the first step is to identify the source. For small leaks around flashing, vents, and seams, roofing cement can be used to seal these areas effectively. However, larger leaks may require a more durable repair, which can be achieved by applying a flat roof membrane in conjunction with roofing adhesive.

Remember, when encountering unusual findings during roof inspections, it’s best to consult with roofing professionals immediately. Promptly addressing leaks can save you from costly repairs down the line.

Improving Drainage

The key to reducing the issue of ponding water on flat roofs is to improve drainage. This can help prevent water from accumulating and causing potential damage. Some effective solutions include:

• Regular cleaning of the drainage system
• Upgrading the drainage system
• Installing scuppers
• Replacing old gutters and pipes with new, more efficient ones

By implementing these measures, you can effectively address the issue of ponding water on your flat roof.

Adding extra drains or constructing tapered sections on a flat roof can significantly improve water flow and mitigate ponding issues. Flat roofs can also be retrofitted with tapered insulation systems to direct water toward drains and alleviate water accumulation.

Tackling Blisters and Cracks

Addressing blisters and cracks on flat roofs requires a professional touch. The professionals will ensure proper ventilation and the use of high-quality materials. The process involves:

1. Cutting out the damaged areas
2. Clearing any trapped water or debris
3. Cleaning the area thoroughly
4. Allowing it to dry fully

After drying the area where the blisters were removed, carefully slice the top to release any remaining moisture, apply roofing cement, and secure the surface. For deeper cracks, a combination of roofing mesh and cement is applied to ensure a durable repair.

Combating UV Damage

Combating UV damage on flat roofs involves applying UV-protective coatings or membranes to shield the roof from sun damage. Reflective roof coatings can deflect sunlight away from the building, reducing heat absorption and the subsequent impact of UV rays.

Cool roof coatings help reflect more sunlight and absorb less heat, which curtails the effects of UV rays on the roofing materials. The roof’s UV protection can be prolonged through the regular re-application of a roof coating every few years.

Routine cleaning of flat roofs contributes significantly to their maintenance by keeping surface temperatures low, thereby enhancing energy efficiency and roof life.

The Importance of Flat Roof Maintenance

Regular inspection and maintenance are crucial in preventing issues and extending the roof’s lifespan. Being proactive and regularly maintaining your flat roof is key to protecting your investment and ensuring the safety and security of your property. Most flat roof maintenance programs include thorough inspections every six months and after significant storm events.

Keeping a clean roof makes it easier for maintenance teams to identify and address minor repairs before they become major problems. Let’s delve deeper into the importance of cleaning and inspecting your roof and the preventive measures you can take to maintain it.

Cleaning and Inspecting

Ideally, flat roofs should be inspected twice a year, once before and once after the rainy season, to detect early signs of wear, such as cracks, blisters, and punctures. Keeping the roof clean is essential for maintenance and can include debris removal through methods such as picking up, leaf-blowing, or pressure-washing. Clogged drains must be cleared to avoid poor drainage.

Professional roofing contractors should conduct annual inspections to check membrane integrity and provide targeted solutions for repair, including the application of sealants and the removal of vegetation to maintain commercial roof integrity or recommend a roof replacement if necessary.

Preventive Measures

Preventive measures are crucial in maintaining the longevity of your flat roof. Here are some tips to help you prevent damage:

• Use durable materials like EPDM for UV protection
• Apply proper sealants to prevent leaks and water damage
• Apply materials dry to prevent blisters
• Allow sealing substances to dry thoroughly after exposure to moisture

By following these tips, you can ensure the long-term durability of your flat roof.

Applying materials with reflective properties, such as certain types of sealants, helps to reduce heat absorption and can also lower energy costs. Also, pest-related damage can be prevented by sealing off roof access points, using bird deterrents or nets, and consulting a pest control expert if necessary.

Choosing the Right Flat Roof Repair Service

When it comes to choosing the right repair service for your flat roof, it’s important to verify that the contractor is fully licensed and insured. Verifying their qualifications provides legal protection and assures their professionalism. Experienced and qualified flat roof contractors contribute to the roof’s longevity and a thorough approach to maintenance and repair.

Modified Bitumen Roofing System Explained

Avoid spending resources on the wrong roofing system for your commercial property, and learn the benefits and properties of a modified bitumen roof. By knowing its advantages and how modified bitumen roofing systems protect your property or commercial building, you can make informed decisions when replacing your existing roofing system.

atlantacommercialroofingcontractors.com gathered the most helpful information about the modified bitumen product, its installation process, the warranty, material cost, frequently asked questions, and the potential problems with modified bitumen roofing systems.

Modified Bitumen – Production Process & Properties

Modified Bitumen (MB) roofing is an asphalt-based roofing system similar to Built-up-Roofing (BUR), designed for structures with low-slope roofs. Modified bitumen roofing membranes appeared first in Europe in the mid-’60s and since have been used in the US and Canada since the mid-’70s.

This roofing system gains its durability from its structure, consisting of a five-layer combination of components, including:

• Insulation – Provides thermal resistance and temperature stability.
• MB Membranes – These membranes are composed of copolymer with polyester or fiberglass reinforcement.
• Modified-Base sheets – These are modified fiberglass base sheets coated with MB asphalt.
• Adhesive – Combined with a bonding agent, this waterproofing material is applied hot or cold.
• Surface – The surface to an MB roofing system increases weather-resistance and shields the roof from ultraviolet rays.

Note: While EPDM roofing material is made from recycled rubber (tires), modified bitumen is made from asphalt and modifying polymer blends.

There are two principal types of MB roofing, including:

APP (Atactic Polypropylene Bitumen) – The use of a thermoplastic polymer gives the asphalt a plastic-like quality. APP modified bitumen increases UV light protection and has greater water resistance.

When APP is torch-applied, the plastic starts melting at 300°F and can be mopped across the roof’s surface, making it easier for roofers to apply.

SBS (Styrene-Butadiene Styrene) – The addition of styrene-butadiene styrene to bitumen gives it a synthetic rubber modification. When heated, SBS becomes sticky and fundamentally different, lacking the liquid flow of heated APP. Since SBS doesn’t melt the way APP does, it requires less heat, which makes it faster to install.

SBS systems can also be installed using cold adhesives, making it suitable for construction or roofing projects where open flames are prohibited.

Benefits of Modified Bitumen Roofing

Some benefits of a modified bitumen roof include:

• Tear-Resistant – The principal advantage that MB roofing has over other commercial roofing systems is its tear resistance. This is due to the combination of fiberglass and/or polyester reinforcement layers under its surface. This trait makes modified bitumen roofing an ideal choice for low-slope roofing with high foot traffic or rooftop equipment.

• Flexible – Flexible low-slope roofing is impact resistant and highly resistant to significant temperature shifts. MB can expand and contract without deforming or losing its structure.

• Energy-Efficient – MB can be installed with a “cool roof” treatment like solar reflectance, resulting in reduced indoor cooling requirements.

• Waterproof – Bitumen is naturally waterproof, and on a well-installed roof, MB is one of the most preferred commercial roofing choices.

• Repair And Maintenance – Repair on an MB roofing system can be done quickly and efficiently using bitumen patches. Low-slope roofing failures usually occur on seals and flashing. However, with proper installation and a roofing maintenance program, such issues should be minimized.


Modified Bitumen Roofing Installation and Warranty

The installation of your modified bitumen roofing system, when properly installed, is a fast, non-intrusive process.

A modified bitumen roofing system can be installed using the torch method, asphalts, or cold adhesives. A standard SBS modified bitumen roof system is a two-ply system applied in rolls overlapping the edge of the previous roll. 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 (when used) to deter bulging and/or sagging
• Correct application of adhesives (when used) to the substrate
• Proper overlapping of MB material
• Drip edge seamlessly connected around the perimeter of the roof

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

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

• A complete list of covered items
• What actions or events may void the warranty
• When/If the warranty expires

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

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

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

An example of material failure would be premature seam failure or blistering. Unless it is determined to result from poor or improper installation, a claim should be leveraged against the manufacturer’s warranty.

Modified Bitumen Roofing Cost

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

Prices for installing a modified bitumen roof system vary depending on the size/complexity of the roof, time of year, material brand and quality, method of installation, and the amount of labor required. 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 ends up bundled in material and installation pricing. Request that it be detailed separately in your estimate(s).

Modified Bitumen Material – will fall between $150 and $300 per square

Modified Bitumen Installation (Labor) – can range from $220 to $350 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 $4,700 and $8,500.

Tip: In the roofing industry, installations are typically more expensive in late spring and summer months. Try to schedule your installation for the off-peak season (early spring and fall) if/when possible.

Disclaimer: The above prices are in no way meant to represent actual bid values and only serve as estimated market price ranges.

Modified Bitumen Roofing Problems

Most problems occurring with modified bitumen roofing systems can be traced back to the roof’s installation. The following are commonly reported issues:

• Improper roof slope causing water pooling and degradation of materials
• Seam separation/defects from improper application of adhesives
• Insulation improperly fastened or installed
• Blisters that develop when moisture penetrates the material

EPDM Roofing System Explained

Avoid spending your resources on the wrong roofing systems for your flat roof or commercial property. By knowing how EPDM roofing systems can protect your commercial building, you can make informed decisions when installing or replacing your roof.

atlantacommercialroofingcontractors.com gathered information about the definition, installation, warranty, cost, and potential problems with EPDM roofing systems while answering frequently asked questions.

EPDM Roofing Explained – Production, Properties, and Benefits

EPDM (Ethylene Propylene Diene PolyMethylene) is a durable synthetic rubber roofing membrane composed of two primary ingredients, ethylene and propylene, derived from oil and natural gas.

The following will explain the composition, properties, and production of EPDM roofing systems for commercial and residential structures, including its use in the auto industry:

• EPDM roofing material is classified as a single-ply membrane. However, most are comprised of two plies of material to produce one ply. This is done to prevent imperfections from occurring throughout the sheet.
• There are two methods used to produce EPDM roofing material; calendaring or through a roller die extruder.
• Sheet thickness is 45 mils, 60 mils, and 90 mils, which equates to about the thickness of a heavy-duty trash bag.
• EPDM panels can be produced as narrow as 5 feet and as wide as 50 feet, while sheet length can reach 200 feet. This provides maximum coverage with minimal seams.
• EPDM membranes are usually installed using deck adhesive, making them fully adhered (glued down) to the substrate. They can also be installed using a ballasted system or be mechanically attached to the substrate.
• Overlapping EPDM seams can be sealed by applying adhesives, seam tape, or both.
• EPDM membranes come in two primary colors, including black and white.
• EPDM membranes are resistant to oil and chemicals expelled by commercial exhaust vents.
• EPDM roofing material is naturally fire-resistant and is highly UV resistant.
• EPDM roofing systems are highly resistant to wind uplift.
• The life expectancy of EPDM roofing systems is between 22 and 35 years
• The EPA recognizes that ballasted EPDM roofing systems can be a very effective means of lowering rooftop surface temperatures, reducing air conditioning requirements within the structure.

Commercial Roof Coatings

Prevent your failing commercial roof from shuttering your business, costing you valuable time and money. Commercial roof coatings can extend the life of your current roofing system by twenty years or more,

atlantacommercialroofingcontractors.com gathered information about commercial roof coating purpose, benefits, installation, types, and maintenance for you to make informed decisions when your commercial roof needs attention.

Commercial Roof Coating Purpose

The purpose of commercial roof coatings is to improve the performance of your roof and increase its lifespan.

Commercial roof coatings protect your property by creating a seamless layer of protection that self-adheres to your existing roofing system. The majority of these coatings are reflective and do not absorb UV rays, keeping your roof and property cooler (making your roofing system a “cool roof”), saving energy and money.

Commercial Roof Coating Benefits

As previously mentioned, commercial roof coatings can help you save money by reflecting UV rays. The benefits don’t stop there, consider the following when determining if a roof coating is the right choice for your building:

No Leaks – Commercial roof coatings eliminate leaks from your roofing system. You may rarely wind up with a leak, but they are easy to fix.

Cool Roof – High solar reflectance (albedo) is the most critical characteristic of a cool roof as it reflects sunlight and heat away from a building, reducing roof and internal temperatures. A high thermal emittance also positively contributes to lowering heat-island temperatures in climates that are warm and sunny.

These properties help roofs to absorb less heat and remain up to 50–60°F cooler than conventional materials during the summer months.

Resistant To Ponding – When your roofing system’s drains get partially or entirely interrupted, water will back up and settle in the lowest areas of the roof. Due to the coating’s seamless application, water penetration is prevented until you can correct the problem with the drainage system.

Low-Cost Solution – A commercial roof coating application is an inexpensive alternative to roof replacement that, when properly applied, can significantly extend the life of your roofing system, making its cost-benefit even greater.

• $8,000 to $16,000 is the range you can expect to pay for a 1,600 square foot flat roof installation (materials and labor).
• $1,040 to $8,000 is the range you can expect to pay for a 1,600 square foot roof coating application (materials and labor).

Longevity – Creating a watertight barrier over your original roofing material can extend its lifespan by as much as 20 years.

Versatility – Commercial roof coatings can adhere to a wide range of substrates. Occasionally, a primer is needed for the coating to adhere to the substrate (more on this below).

Easy Installation – When applying a commercial roof coating, contractors will save time and headaches. At the same time, building owners can get their roof revamped faster for less money and without interrupting operations within the building.

While there are impressive benefits associated with nearly every aspect of commercial roof coatings, if your roof has suffered catastrophic damages or has completely failed, it may be necessary to replace it altogether.

Commercial Roof Coating Installation

A roof coating installation is a simple process. As mentioned above, it is one of the benefits. The following will bring into focus just how easy it truly is:

Roof Inspection – A roof inspection is the first step in this process, and the professional performing it will be looking for the following:

• Storm, animal, or impact damages
• Shrinkage (membrane roofing systems)
• Damaged sheet metal (metal roofing systems)
• Damaged flashing
• Loose protrusions
• Drain blockages
• Pooling water
• Previous or current leak damage
• Structural integrity

These inspections are most effective when performed within 48 hours after rainfall.

Roof Repairs – Once your inspection is done, you’ll have a list of damages or irregularities to fix. Before you can apply a roof coating, all problems must be halted and removed. If a roof coating is applied to a roof with wet insulation, loose protrusions, structural problems, etc., those problems will be sealed in and continue to cause problems.

Clean the Roof – Once all repairs are complete, the final activity before installation is to clear the roof of:

• Tools and equipment
• Debris
• Dirt
• Oil/Exhaust buildup

Remove everything that is not a part of the roofing system. Using a power-washer, brooms, and industrial vacuums are effective ways of cleaning your roof before coating application.

Install the Roof Coating – After the roof has been inspected, repaired, and cleaned, your roofer can properly apply your roof coating. Coatings can be applied by rolling them on or spraying them on the roof’s surface. Done correctly, the coating will cure over 24 hours, leaving your roofing system rejuvenated and sturdy for up to 20 years.

Commercial Roof Coating Types

The following are common types of roof coating that can be applied to your existing commercial roofing system:

Acrylic Coatings – Acrylic coatings come in solvent and water-based formulas, and the qualities of the coating depend on the selected formula. Acrylic coatings have outstanding weathering properties and reflect UV rays. The selection of a formula depends on the type of the roof, adhesion, regional temperature fluctuations, etc.

Silicone Coatings – Silicone coatings are commonly applied in regions subject to an abundance of rain, leaving the roof wet for long periods. These coatings are also highly effective at reflecting UV rays, helping commercial structures stay cool.

Butyl Elastomeric Coatings – Butyl elastomeric coatings are made from butyl rubber and possess excellent flex properties, adhesion to multiple substrates, and resistance to most weather and temperature conditions.

Read more about butyl elastomeric coatings at atlantacommercialroofingcontractors.com/butyl-elastomeric-roof-coating-explained/

Polyurethane Coatings – Polyurethane coatings are solvent-based and come in either aromatic or aliphatic variations. Polyurethane coatings have high abrasion resistance traits and are preferred on roofing systems with high foot traffic or regions that experience frequent hailstorms.

Commercial Roof Coating Maintenance

Should you acquire a maintenance program to cover your roof coating and roofing system?

Yes. In the same way you would contract a professional roofing service to maintain your roof without a roof coating, you should acquire an equivalent maintenance program once your roof coating is installed. Some of the benefits include:

• Bi-annual inspections
• Emergency inspections after severe weather
• Light maintenance and repairs
• Preventive maintenance
• Gutter and drain cleaning
• Debris removal

For more in-depth information about maintenance programs and services, read atlantacommercialroofingcontractors.com/maintenance-programs-services/

Commercial Roof Recoating

One of the added benefits to getting a roof coating is that once you near the end of its lifespan, you can have it recoated, adding another 15 to 20 years to the life of your roofing system.

Note: Some municipalities have codes that address commercial roof recoating and may limit the number of times a roof can be coated before requiring repair or replacement. Visit your city’s website and search for “roofing codes” or call their “Office of Buildings/Construction” for more information.

Coating Your Commercial Roof

In this article, you discovered information about the purpose, benefits, installation, types, and maintenance programs associated with commercial roof coatings.

By informing yourself about commercial roof coatings, you can make well-informed decisions when it’s time to address roofing issues, or take action to prevent them.

Allowing your roof to remain fully exposed to the elements can dramatically reduce its lifespan, leading to premature problems and failure. Significant problems or premature replacement can lead to you exceeding your roofing budget and costing your company capital that could be used in other areas.
