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.

How To Install Metal Roofing Over Shingles

Don’t unnecessarily pay to tear off your shingle roofing system if you are replacing it with a metal roofing system. Knowing how a metal roof can be installed over a shingle roofing system will help you make an informed decision and save money on your roof installation.

atlantacommercialroofingcontractors.com gathered the following information about how metal roofing systems can be installed over top of a shingle roof, its benefits, and its drawbacks.

Installing a Metal Roof over Shingles

Shingle roofing systems have a typical lifespan of 20 to 30 years when properly installed with good quality materials. Metal roofing, however, can last upwards of 50 years or more, making it a worthwhile investment. There are several Metal Roofing Advantages and Disadvantages, so consider the following when installing a metal roof:

Installation – Metal shingle systems are installed over a framework made of 2x2s. Such framework offers three significant advantages:

• The framework/rafters is/are fastened directly to the deck (through the existing shingle roofing system), then standing seam sheets (running from top to bottom), or interlocking shingles/R-panels (installed horizontally like shingles) are fastened to the framework.
• The framework creates a flat and straight surface even when shingles are curled, or the roof ridge is warped.
• The framework also creates a ventilation gap helping prevent ice dams during winter months and works to cool the roof during summer months.

Ventilation holes are cut in the old roof above the soffit. This pulls air through the soffit vents (from underneath), helping remove moisture and heat from the roof.

Note: You may find metal roofing options somewhat overwhelming. From sizes to colors, selecting the roofing style and appearance may be more complicated than the actual installation.

How Much Does it Cost to Install a Metal Roof over Shingles?

While there are some variables when calculating installation costs for a metal roof over a shingle roof, here is what to expect when bidding out this project:

• $-Varies – Shingle roof repairs (needed before metal roof installation)
• $40 Each – 2” X 2” rafter installation
• $150/square (1 square = 100sqft) Standing seam installation or
• $120/square R-Panel installation
• $5/square installed
• $-Varies – Trim, gutters, and finishing

Tip: Regardless of the roofing system you plan to have installed, collect a minimum of three estimates, contractor references, and their maintenance program pricing and coverage.

Can You Put Metal Roofing Directly over Shingles?

Yes. In fact, here are some of the benefits of installing a metal roofing system over a shingle roof:

Convenience – Installing a metal roof over shingles is convenient because there is no tear-off mess or disposal of old/used roofing material.

Cost-Effective – You save on both labor and material. There is no tear-off and disposal cost, and the roofing system’s substrate is already in place.

Sound Reduction – Metal roofing systems can be very noisy. A shingle roofing system under a metal roof acts as an excellent sound reducer.

Better Insulation – Having a shingle roofing system under a metal roof significantly improves the structure’s insulation.

Increased Water Resistance – Effectively, your roof will have twice the protection when a metal roof is installed over shingles, significantly reducing the chances of leaks.

Wind Resistant – A well-installed metal roof over a shingle roof can withstand severe winds up to 120 mph.

Practicality – While shingles are a relatively inexpensive roofing material, they require more frequent maintenance and shingle replacement. Well-installed metal roofing not only minimizes the need for maintenance. It eliminates the constant need for damaged shingle replacement.

Value – A metal roofing system can also add curb appeal to a structure since they come in a wide variety of sizes, styles, and colors.

Note: If the new metal roof is properly installed over your shingle roof and your roofing contractor does everything correctly, this type of roofover can be done without issues. As mentioned, you can save up to 25% in labor by not tearing off your old roof, installing new underlayment, or paying fees to dispose of old roofing materials.

Watch this video about metal roof installation over shingles.

Do I Need Underlayment for a Metal Roof over Shingles?

If your metal roof is being installed over asphalt shingles, your roof already has an underlayment and likely won’t need another. However, shingle expansion and contraction could eventually damage the back of the metal.

Note: While an underlayment may not be required for a metal roof over shingles, it is highly recommended for its capability to extend the lifespan of the roofing system.

Tip: In some municipalities, roofing codes will require underlayment installation, even if you are installing the roofing system over shingles.

Should You Install Metal Roofing over Shingles?

While there are many valuable benefits to installing a metal roofing system over shingles, there are some potential disadvantages. Consider the following:

Leaks and Rotting Wood – Before installing a metal roof over shingles, existing leaks and rotting rafters or decking in the shingle roofing system should be addressed and repaired. Leaving such problems unresolved can adversely affect the performance and lifespan of your new metal roofing system.

Note: Once water gets by your metal panels, it’ll run down and across your old shingle roof. This water will keep running until it finds problem areas and begins leaking inside your home. Since these leaks originate from two different locations of two separate roofs, they will be hard to track down and repair.

Roof Weight – Inspect your existing roof for any signs it has exceeded its roof load. These signs will likely appear as sagging decking or buckling trusses. This is a common problem with roofing systems that have multiple layers of shingles or other roofing material.

Note: Municipal construction codes will often dictate how many “layers” of roofing may be installed on a structure before having to tear off the roofing system and start over from the substrate or decking.

Inspection Difficulty – Installing metal roofing over shingles presents a certain level of uncertainty regarding the integrity of the roof decking and structure, as it remains covered up by the shingle roofing system.

Metal Roof Installation over Shingles

In this article, you discovered information about installing a metal roofing system over an existing shingle roof, its benefits, and disadvantages.

Save money and time by having a metal roofing system installed over your existing shingle roof, and know what is involved in the process to help you make informed decisions when hiring a contractor for the job.

Not knowing what to look for when installing a metal roof over shingles or hiring a contractor ill-equipped to complete the job can lead to catastrophic roof damages, loss of valuable resources, and potentially severe structural damage.

When Does a Roof Need To Be Replaced?

Prevent catastrophic damages and injuries from a failed roofing system. Knowing how long different roofing systems are supposed to last will help you get it evaluated and replaced when the time is right.

atlantacommercialroofingcontractors.com gathered the following information to help you determine when your damaged or aging roofing system needs to be replaced.

What Impacts How Long a Roof Lasts?

Each type of roofing system has a projected lifespan. What determines a roofing system’s longevity includes:

• Bi-annual inspections (spring and fall) under a maintenance program
• Early detection of hidden problems/defects in the roofing system
• Material quality
• Installation quality (workmanship)
• Weather patterns (severe weather events like hail, tornadoes, hurricanes, etc.)

A well-installed roofing system with continuous maintenance, care, and eventual repairs can last from 20 to 100 years, depending on the roofing material. Consider the following roofing systems:

Composition Shingles 15 – 40 Years

Composition shingles are a composite product made from a fiberglass or cellulose mat, asphalt, and mineral granules. Composition shingle roofing systems are also environmentally friendly. Most composite roof materials are made with a paper backing and produced using recycled materials.

This durable roofing system can last an average of 15 to 20 years with minimal maintenance and care. When properly installed and maintained, this roofing system can last up to 40 years.

Signs that a composition shingle roof replacement may be necessary include:

• Visible signs of roof or shingle aging
• Multiple leaks
• Missing mineral granules
• Shingle curling (most common along edges)
• Missing shingles
• Moss growth on shingles
• Algae growth (dark stains running down the roof slope)

Severe weather events are common factors in roofing system damages and failures. After such events, your roofing system should be inspected and repaired if possible.

Note 1: A typically hidden problem with shingle roofing systems is bad shingle adhesion. Contributing factors often include manufacturing inconsistencies, poor installation practices, advanced aging and shingle deterioration, cold weather installations, lack of attic ventilation, and repeated thermal expansion and contraction.

Note 2: Another, often hidden, issue occurs when gaps or openings are left in a roofing system's eaves, soffit, or fascia. These openings allow small animals/wildlife to enter attic space, destroying insulation or compromising a roofing system's integrity from the inside out.

Asphalt Shingles 10 – 20 Years

Asphalt shingles are not made solely of asphalt. They consist of either a fiberglass or felt paper base coated with a waterproof layer of asphalt and topped with mineral or ceramic granules. Over the past four decades, fiberglass-based shingles have been the more requested product.

This roofing system can last an average of 10 to 15 years with minimal maintenance and care. When properly installed and maintained, this roofing system can last up to 20 years.

Similar to composition shingles, signs that an asphalt shingle roof replacement may be necessary include:

• Visible signs of roof or shingle aging
• Multiple leaks
• Missing mineral granules
• Shingle curling (most common along edges)
• Missing shingles
• Moss growth on shingles
• Algae growth (dark stains running down the roof slope)

Note: Shingle roofing systems often hide water damage from failed flashing in valleys, around chimneys, and in poorly constructed chimney crickets or saddles. This type of failure can lead to multiple leaks, deck rotting, and eventual roof failure.

Severe weather events are common factors in roofing system damages and failures. Again, after such events, your shingle roofing system should be inspected and repaired if possible.

Wood Shingles Up to 30 Years

Wood shake roofing and a wood shingle system are both typically made from cedar, cypress, redwood, or pine. While these wood products have similarities, they're produced differently. Wood shingles are usually machine cut on both sides, and wood shake material is created by splitting rectangles from a log.

Being rot and insect resistant, a wood shingle roofing system can last up to 30 years with diligent annual upkeep.

Signs that wood shingle or wood shake roof replacement may be necessary include:

• Visible signs of aging or damage in multiple areas of the roof
• Multiple leaks
• Cracking, splitting, or warping shingles
• Missing shingles

Often, these signs will be confined to a section of the roof, which may mean only a repair is needed.

Note: A commonly hidden problem with wood shingle roofing systems is a poorly ventilated attic. Moisture that cannot escape the attic is forced upward through the roof structure causing shingles to curl and buckle. This uneven warping traps water, exacerbating the roof's deformation and rapid decay of its framework.

Single-ply Membrane (TPO & PVC 15-30 Years, EPDM 30-50 Years)

Single-ply membrane roofing systems require fewer seams than asphalt roofing systems and don't require torches or hot asphalt for installation. Single-ply systems come with prefabricated finishing accessories that make installation easy. Consider the following:

TPO – TPO (thermoplastic polyolefin) is a single-ply membrane and is one of the fastest-growing commercial and residential roofing systems. TPO roofing systems are made of a single layer of synthetics and a reinforcing scrim used to cover flat roof substrates.

Because TPO is relatively new in the roofing industry, its full lifespan has yet to be determined. This roofing system can last an average of 15 to 20 years with minimal maintenance and care. When properly installed and maintained, this roofing system can last up to 30 years before replacement.

To learn the benefits, cost, and problems related to a TPO roofing system, read the TPO Roofing System Explained article.

Signs that a TPO roof replacement may be necessary include:

• Visible signs of aging or damage in multiple areas of the roof
• Multiple leaks
• Chronic ponding
• Severe alligatoring (shrinkage and cracking)

Note 1: Often overlooked and elusive are damages caused by a parapet wall's failed metal coping. This roofing system malfunction allows water to collect between the TPO membrane and roof substrate, ultimately resulting in leaks, membrane deterioration, and structural damages to the building.

Note 2: Another hidden problem for flat or low-sloped roofing systems occurs when internal drainage (drainage routed through the structure) becomes clogged. A blocked drainage system can lead to ponding and severe water damage requiring costly structural repairs and roofing system replacement.

Detected early, these issues can be halted with repairs. When the roofing system becomes compromised in multiple locations, replacement may be the only option.

PVC – PVC (polyvinyl chloride) roofing is a single-ply roofing system used on commercial, industrial, and residential flat or low-sloped roofs. PVC is among the world’s most widely produced synthetic plastic polymer.

Like TPO, this roofing system can last an average of 15 to 20 years with minimal maintenance and attention. When properly installed and maintained, a PVC roofing system can last up to 30 years before replacement.

Like TPO, signs that a PVC roof replacement may be necessary include:

• Visible signs of aging or damage in multiple areas of the roof
• Long tears or rips
• Multiple leaks
• Chronic ponding
• Severe alligatoring (shrinkage and cracking)

Note 1: Improperly welded or damaged seams can allow water infiltration, often remaining undetected until extensive damages have occurred to the roofing membrane and substrate, requiring the roofing system's replacement.

Note 2: Foot traffic to and from electrical equipment and other rooftop installations can result in membrane tears and roofing system damage that can also go undetected until such damages require extensive repairs or roofing system replacement. This type of damage can be prevented by installing reinforced walkways or paths wherever foot traffic may be required.

Detected early, these issues can be halted with repairs.

PVC is somewhat similar when compared to TPO, but there are some unique advantages and we suggest knowing The Difference Between PVC and TPO Roofing Systems.

EPDM – EPDM (ethylene propylene diene polymethylene) is a durable synthetic rubber roofing membrane produced using two primary ingredients, ethylene and propylene, derived from oil and natural gas.

Utilized worldwide in the roofing industry, EPDM membranes exhibit a high level of stability as they age. This roofing system can last an average of 30 years with minimal maintenance and care. However, when properly installed and maintained, an EPDM roofing system can last up to 50 years before requiring replacement.

Signs that an EPDM roof replacement may be necessary include:

• Visible signs of aging or damage in multiple areas of the roof
• Long tears or rips
• Multiple leaks
• Chronic ponding
• Severe alligatoring (shrinkage and cracking)
• Use of improper repair materials, including asphalt and roofing cements

Note: One of the more elusive complications for this and all other flat roofing systems is an incorrect slope (these roofing systems are often referred to as low-slope roofing systems). If the slope is too low, ponding can occur with heavy precipitation or even the slightest drainage obstruction. Ponding or water pooling leads to rapid deterioration of all roofing system components and will likely result in the need for a complete roofing system replacement.

To learn more of the benefits, installation process, cost, warranty, and problems with an EPDM roofing system, read EPDM Roofing System Explained.

Built-up Roofing (BUR) 30+ Years

Built-up roofing systems consist of multiple layers of asphalt alternated with felt sheets applied over the roof deck (substrate), vapor retarder, and insulation that is attached to the roof decking. The system is then covered with a reflective membrane (cap sheet) or coating system.

Depending on the climate and materials used, a built-up roofing system has an average lifespan of 20 years. Well-installed and maintained BUR systems have been known to last 30+ years.

Signs that a BUR roof replacement may be necessary include:

• Multiple leaks (especially after having been repaired)
• Chronic ponding
• Severe weather or impact damage

Note: Leaks occurring in a built-up roofing system are often elusive, remaining hidden until severe damage has occurred to the roofing system and building structure. When a layered roofing system such as this develops multiple leaks, the likely course of action is to replace the system entirely.

To learn more of the installation process, benefits, cost, warranty, and potential problems with a Built-up roofing system, read the Built-up Roofing System (BUR) Explained article.

Modified Bitumen (ModBit) 15 – 25 Years

Modified Bitumen (ModBit) roofing is an asphalt-based roofing system similar to Built-up-Roof (BUR) and is designed for structures with low-slope or flat roof structures. Its five layers of protection make this roofing system one of the most trusted in the industry today.

Location, maintenance, and roof design are influencing factors on this system’s longevity. This roofing system can last an average of 15 years with minimal maintenance and care. When properly installed and maintained, a ModBit system can last up to 25 years before needing replacement.

Very similar to BUR, signs that a ModBit roof replacement may be necessary include:

• Multiple leaks
• Chronic ponding
• Severe weather or impact damage

Note 1:When this or other flat roofing systems are ballasted with gravel or stone, repairs will often require the removal of that gravel or stone. This process may ultimately require the partial or complete replacement of the roofing system.

Note 2: A common and barely noticeable problem with ModBit roofing systems involves vibrations from mechanical equipment causing mechanical fasteners to loosen and back out, leaving holes in the membrane. As this condition progresses, severe water damage including rusted components, substrate or decking deterioration, leaks, and costly structural damages occur and can remain virtually unnoticed until a partial or total failure of the roofing system.

Note 3: Roof coatings are commonly applied to aging roofing systems to extend their lifespan. In doing so, a roof coating may fail, allowing slow leaks to develop and remain undetected until severe structural damages occur. These damages become evident as interior leaks, sagging areas in the roof, severe ponding, and roofing system failure if left to develop.

To learn more about the modified bitumen product, benefits, warranty, cost, and potential problems with this roofing system, see this Modified Bitumen Roofing System Explained article.

Metal Roofing Up to 70 Years

Metal or tin roofing is a popular roofing system around the United States and in Canada. The term “tin” is used interchangeably with metal, steel, or galvanized steel roofing. However, tin is an incredibly rare element and unused for roofing.

This incredibly durable roofing system can last an average of 25 to 40 years with minimal maintenance and care. When properly installed and maintained, a metal roofing system can last up to 70 years before requiring replacement.

Signs that a metal roof replacement may be necessary include:

• Multiple leaks
• Rusting components
• Multiple damaged panels
• extensive weather or impact damage

Note: Due to the expansion and contraction of metal roofing, fastening and anchoring systems can weaken and fail over time. This problem can result in complete roofing system failure and is often only detected during routine maintenance visits.

To learn whether this type of roof suits your needs, read Metal Roofing Advantages and Disadvantages.

Clay Tiles 50 – 75 Years

In use since the 17th century, clay tiles are made by baking molded clay. Tile density is determined by heating time and at what temperature. Known for their ability to withstand high winds, hail, and fire, these tiles are produced in white, yellow, orange, and brown shades.

A clay tile roofing system can last an average of 50 years. With proper installation and maintenance, a clay tile roofing system can reach 75 years before replacement is needed. In rare cases clay tile roofing can even reach a whopping 100 years.

Signs that a clay tile roof replacement may be necessary include:

• Multiple cracked, damaged, or missing tiles
• Roofing system sagging
• Severe weather or impact damage

Note: While clay tile roofing systems can be long-lived, flashing failures (corrosion or cracking), and fastener failures (rusting) often result in water damage to the roof's decking and multiple leaks in the structure below. This type of damage can remain dangerously elusive, only appearing during a maintenance inspection or when the roofing system partially or completely fails.

When damages are minimal or confined to a small area, clay tile roofing systems can be easily repaired. More extensive damages will likely require partial or full replacement.

Roofing Maintenance Program

Roof maintenance plans are provided by commercial and residential roofing contractors, in which they agree to perform scheduled inspections, cleaning, debris removal, and scheduled or recommended preventative roof maintenance.

Acquiring a roofing maintenance program from a licensed roofing contractor allows property owners to protect the roof’s warranty provisions, extend the roof’s lifespan, and ultimately save money by preventing significant damages and costly repairs.

Most roof warranties require a minimum of one roof inspection per year performed by an authorized contractor. These inspections allow early detection of problems and their timely repair before developing into catastrophic problems, leading to a roof’s replacement.

Commercial Roofing Maintenance Programs and Services can greatly extend the life expectancy of your roofing system. If you are beyond repair and in need of a new roof, consider starting a maintenance plan after its replacement; a preventative service will add years to the life of your roof, and considerable savings to your investment.

Commercial And Residential Roof Replacement

In this article, you discovered information about roofing system longevity to help you determine when your roof should be repaired or replaced.

When you know your roof’s projected lifespan, the durability of its materials, and have diligently provided for its care and maintenance, it is likely that your roof will far outlive its life expectancy.

Ignoring your roof and its maintenance needs will sharply abbreviate its lifespan, potentially leaving you with costly repair bills, significant leak damage, and in need of an emergency replacement when it suddenly fails.

Commercial Rooftop Deck Construction

Prevent your commercial rooftop deck from being improperly installed, and discover design ideas and inspirations. By converting your roof or a portion of it into a deck, you can gain a recreation area, lounge or meeting space with a beautiful view.

atlantacommercialroofingcontractors.com outlined below keys to constructing a deck on your commercial rooftop, the steps to ensure it is done correctly, and answers to some frequently asked questions.

Rooftop Decks

Before investing your time and resources into planning a rooftop deck, there are some questions you will need to answer:

Are Commercial Rooftop Decks Permitted in My Municipality? – Contact your local zoning and development or planning department to inform yourself about ordinances for constructing a rooftop deck. Inquire about the following:

• Are rooftop decks (open or enclosed) allowed in your municipality?
• Is a building (or other) permit required for this project?
• Are there any application or permit fees?
• What documents must be provided with a permit application (blueprints, building/roof inspections, etc.)?

Note: Unlawful building/construction activities can result in costly fines, mandated removal of the construction, and further punitive actions

Will My Commercial Building Support a Rooftop Deck? – There are two numbers you need to know before initiating any type of construction or installation on your roof:

1. What is your roof’s load capacity?
2. What is your building’s load capacity?

Load capacity is broken down into several categories. These include:

• Dead Load (permanent or static structural elements)
• Live Load (produced by the use and occupancy of the building)
• Environmental Load (wind, snow, ice, and rain loads)
• Self-Weight (the weight of the building)

Before plowing ahead, read more about commercial roof load to ensure your new rooftop deck can be properly supported.

Plan Your Rooftop Deck Design

Gardens, gazebos, hot tubs, pools, etc. What are you looking for in a rooftop deck? Consider these elements:

• Plants and trees (green roof)
• A pergola
• Seating/Lounging furniture
• Recreational activities (games)
• Water (pool, fountain, etc.)
• Wet bar
• Kitchen/Grill

Hire a professional designer to help you plan the details of your space, then run the designs by your engineer. The more you plan in the beginning and vet the project using experienced professionals, the better quality material and workmanship you will end up with.

Watch this video to see multiple deck configurations and ideas.

Rooftop Decking and Deck Framing – Of your building installations, a rooftop deck, will most likely be the most punished by sun and weather. When selecting your decking, take the following into consideration:

• Composite or synthetic decking ranges from wood composites to plastic capped wood composites and cellular PVC. This decking is usually available in a variety of colors.
• High-density hardwood is an excellent consideration for the rooftop. You can find numerous high-performance hardwood decking species.
• Softwood decking is not as reliable on a rooftop deck. This decking is more likely to split, crack, and warp. Even the higher-quality softwood decking alternatives, like cedar, require a lot of refinishing. Otherwise, you can expect lots of splitting and warping.

Note: The thicker and more narrow the deck boards are, the better they will perform. Also, the more vertical clearance you have between the top of the roof and bottom of the deck, the better. Spacing between deck boards also plays a critical role in ventilation.

You’ll find that several types of deck framing can be installed:

• Sleepers are one way that builders have designed to mitigate moisture and the spread of rot. Sleepers are similar to wooden support framework that the deck rests upon.
• Wood framing is the traditional option and is extremely low-cost upfront. However, this type of framework may exceed your roof load. Another downside is the potential for twisting, warping, and rotting.
• Aluminum framing (joists) are high performance and perhaps the best option. While this framing requires a higher initial investment, it will not twist, warp, or rot.

Tip: Request references from your contractors that you can visit. Seeing and walking on a finished deck will help you make informed decisions when selecting your project materials.

Assemble Your Deck Team – One of the more time-consuming activities of your rooftop deck construction will be vetting your contractors. You’ll want to collect a minimum of three bids from multiple contractors, evaluating experience, pricing, guarantees, warranties, references, and overall qualifications. Consider the following:

• If you don’t already have a commercial roofing company, you will need one to scrutinize your roofing system, verifying that it is leak and problem-free. Some roofing companies are fully capable of installing a rooftop deck.
• The engineer will help you determine if your roof and building can support your deck’s additional weight.
• A landscape architect will help you design and place plants, trees, shrubs, and their containers.

Shop around, whether you hire multiple contractors or locate a company that can work “concept to completed installation,” take your time and choose wisely.

Frequently Asked Questions

Question: Does a Rooftop Deck Count as Square Footage?

Answer: Yes, when included in “Rentable Square Footage”(RSF), also known as “Useable Square Footage” (USF).

Question: Does adding a roof deck add value?

Answer: Yes. Adding a rooftop deck can add from $20,000 to $50,000 or more, depending on material, construction, and degree of luxury finishes.

Question: How much does it cost to build a rooftop deck?

Answer: For a basic installation, you can expect to see pricing between $20,000 and $25,000. For more luxurious or elaborate installations, pricing can easily exceed $50,000

Commercial Rooftop Decks

In this article, you discovered essential information about installing a rooftop deck on your commercial building, making sure it’s done right, and answers to frequently asked questions.

Investing in a rooftop deck will add valuable square footage to your building while increasing its overall value.

If you leave your roof undeveloped, you are missing an opportunity to add value to your building and create a unique space otherwise considered “dead space.”

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.

Chimney Leak Repair

Prevent your leaking chimney from causing costly damage to your property. Knowing how to detect and repair a leaking chimney will help you keep your structure dry and safe.

atlantacommercialroofingcontractors.com gathered information on how to identify leaks in your chimney, what causes them, and how to repair them.

Chimney Leaks

Every functioning chimney has one feature in common, a hole in your property. When the engineering of your chimney fails, it can allow water in, sometimes unnoticed. Here’s how to identify a chimney leak:

• Pooling water near and/or around your fireplace or stove
• Wet spots or streaks running down the wall near your chimney
• Wet spots on the ceiling around your chimney
• Wet framework around your chimney in your attic
• Water or condensation in the firebox
• Sound of dripping or trickling water in the chimney
• Cracked or spalled masonry (internal or external)
• Musty or moldy odors after a rainstorm

Note: While leaks can pop up at any time, most will develop and become evident in the spring and summer after severe, rainy weather events.

Watch this video to see what brick and mortar problems look like on a chimney.

Chimney Leak Causes

Once you suspect that you have a leaking chimney, such leaks can be traced back to one of the following six installation or material defects:

1. Missing or Poorly Installed Chimney Cap – If your chimney is not covered by a chimney cap, it is poorly installed, or it is too small, rain can enter your flue and fall down the chimney, soaking masonry and brick.

2. Damaged Chimney Crown – The chimney crown is a cement cover atop your chimney that protects flue tiles and chimney liner. When the chimney crown is damaged or cracked, water can cause moisture damage throughout the flue system, fireplace, and damper.

3. Cracked or Missing Chimney Liner – A chimney liner directs combustion byproducts away from your property while protecting the inside of the flue and the chimney’s masonry material from getting soaked by condensation when chimney temperatures cool down.

4. Faulty or Poorly Installed Flashing – Flashing is the material used to seal a chimney’s penetration through a roof. This flashing is supposed to divert rainwater from coming through the roof, eventually damaging your chimney and property.

5. Brick and Mortar Damage – The exterior portion of your chimney is exposed to all weather conditions, all of the time. Brick and mortar damage can occur from weathering, poor construction, and/or impacts from uncontrolled vehicles or falling trees.

6. Missing or Damaged Chimney Cricket – Another common cause for chimney leaks is ponding water on the penetration’s uphill side. This ponding water can deteriorate flashing, damage brick and mortar, and result in significant roofing system damage. A properly installed chimney cricket creates a sloped high point to divert water that would otherwise pond against the chimney.

Now that you have located the source of your chimney leak, repairs should begin immediately to prevent further damage to your chimney or property.

Repairing Chimney Leaks

Some chimney leaks can be repaired by the property owner, while other repairs may require professional assistance. Consider the following:

1. Installing or Replacing a Chimney Cap – If you can safely get on your roof (only perform this work with proper fall protection), the following steps will help you properly install a chimney cap:

• Measure the flue at the chimney top
• Purchase an appropriately sized chimney cap (the bonnet or roof of the cap should be twice as large as the flue opening)
• Read the instructions and gather the tools you will need
• Install the chimney cap according to the manufacturer’s instructions
• Make sure all fasteners are tightly secured, and the cap is securely in place

Tip: Stainless steel caps are generally higher quality and more durable.

2. Repairing or Replacing a Chimney Crown – This repair can be done as a temporary or permanent fix. Consider the following:

• (Temporary) Seal a cracked chimney crown with silicone caulking, an elastomeric coating, or other sealants as a temporary fix.
• (Permanent) Remove the damaged crown, build a wooden form (to hold the cement in place until fully cured), add rebar (to strengthen the crown), and pour a good quality cement mixture into the form and over the rebar.

Note: The temporary fix above will likely last two or three years before failing.

3. Installing a Chimney Liner – Installing or replacing a chimney liner is an easy project for property owners that enjoy DIY projects. (The following configuration will connect to a stove pipe. There are multiple configurations for different chimneys and/or appliances.) The following steps will help you install a new chimney liner:

Step 1 – Gather the tools you will need:

• Cutting or razor knife
• Flathead screwdriver
• Caulk gun
• Protective work gloves
• Safety glasses
• Hacksaw or Electric grinder
• Power drill

Make sure your tools and equipment are in good working condition.

Step 2 – Assemble the chimney liner kit:

• Stainless steel chimney liner
• Connector (some installations may require a two-part tee connection)
• Top plate
• Rain cap

Note: Chimney liner kits can be customized to fit any chimney and/or appliance/fireplace.

Step 3 – Remove the plastic wrap the liner is coiled in. Straighten the liner, making sure to avoid puncturing it. Straighten the liner out as well as you can.

Step 4 – Connect the tee to one end of the chimney liner. Use a tee with a looping hose clamp to avoid drilling screws through the liner.

Step 5 – Insert the liner and tee (tee first) down the chimney flue. Lower the liner until you reach the thimble (the thimble is the hole on the side of the chimney where a stovepipe is attached).

Step 6 – Complete the tee connection installation:

• Insert the horizontal part of the tee (hose clamp end first) into the thimble.
• Work the vertical part of the tee through the horizontal hose clamp until the edges of the tee are inside the horizontal section. 
• There is a worm screw inside the horizontal part of the tee. Tighten the worm screw until the two parts of the tee contact each other.

Step 7 – Connect the stovepipe. Stovepipes typically come with three screws per connection joint. Drive the screws into the horizontal part of the tee and through the stove’s exhaust collar.

Step 8 – Install the top plate:

• Run a bead of silicone sealant along the top edge of the flue
• Run the chimney liner through the top plate and place the top plate squarely atop the flue
• Center the top plate on the flue and secure the top plate by screwing in the locking bolts to the sides of the flue.
• Cut the excess liner, so it is flush with the top edge of the top plate.
• Once the liner is cut flush with the top plate, tighten the worm screw, so the hose clamp tightens around the liner.
• Install the cap over the top plate, and tighten the clamp to secure it in place.

Note: When chimney liners are purchased as a kit, all of the pieces requiring assembly should be fitted, only requiring simple fasteners.

4. Repairing Damaged or Installing New Flashing – Over time, flashing can be damaged by severe weather, material decay, or time. Similar to replacing caulking around door or window joints, scrape away the old caulking and reapply with a sealant. You can also find two-part kits containing a reinforcement fabric and elastomeric sealant. Utilizing a fabric with the sealant will increase its life. This repair, however, will only provide a few years of chimney leak relief.

If your chimney flashing is deteriorating, it is likely that your roofing system may be in decline. Read more about flashing and you will understand its purpose and the various types.

5. Repairing Brick and Mortar Damage – This type of repair requires the replacement of the damaged brick and mortar. Short-term solutions like caulking will only last for a matter of months.

If you are not comfortable with masonry, hire a trusted handyman or contractor to remove and replace damaged or cracked bricks and softening mortar.

6. Replacing or Installing a Chimney Cricket – Replacing and/or installing a chimney cricket is considered a major chimney repair. This repair should only be performed by a trusted chimney service or a professional roofing company.

Watch this video to see a well-installed chimney cricket.

Note: If you have any doubts or difficulties regarding any of the chimney leak causes and/or repairs mentioned in this article, contact a professional chimney service or roofing company to perform the needed repairs.

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.

Inspecting a Commercial Roof

In this article, you discovered what to look for during a commercial roof inspection and how to address problems when they arise.

By knowing how to inspect your roof, you can stop minor issues before they develop into expensive problems.
