Roof Coatings and Commercial Spray Foam Insulation

Renew Your Old Roof with Silicone Coatings


One of the most time-consuming and energy-draining projects you’ll ever undertake as a building owner is to replace your roof. Tearing out your old roof and replacing it with a new one is a lengthy process that can give you gray hair if you’re not careful. If this is such a hard process, why do some many building owners elect to replace their roof in traditional fashion? The main reason is that they aren’t aware of silicone coatings and the fact that they can renew their old roof. If they do know that coatings are available, many people are unsure of whether or not they work. Coatings are a fairly new product and don’t have the history that other roofing systems do. However, in their lifespan, roof coatings have already proven that the provide great protection and are a good roofing system.

Renew your old roof

Tear-off takes time and is expensive. The more of it you do, the more money required.

Avoid Tear-Off When You Renew Your Old Roof

When you use a silicone coating to renew your old roof, you can skip the roof tear-off step altogether. Silicone roof coatings can adhere to nearly any roof system, so you don’t have to tear the existing roof off. Simply clean the existing roof and install the silicone coating right over top of it. This saves you time, money, and helps keep waste out of landfills.

Extend Roof Life

Silicone coatings also extend the life of your roofing system. They provide complete protection from the elements, including the sun and wind. Your roofing system won’t break down as it can when it’s exposed to the elements, so as long as you maintain the roof coating you can expect the roof to last a long time.


Don’t worry about replacing your old roof, renew it with a silicone coating! You can save time and money by eliminating tear-off, reducing waste, and extending the life of your existing roof. Call us today if you’d like to learn more about how you can renew your old roof.

Closed Cell Foam as an Air Barrier

d1e66dcdf6a405bf1df096a7b4a9dca076fe5c49With a proven performance record, ccSPF offers an integrated air barrier solution providing superior thermal insulation, while helping prevent moisture and air infiltration. The key elements affecting air infiltration are wind, stack effects and pressure differentials. Let’s take a look at the many benefits that a well-designed ccSPF air barrier system can provide. CcSPF can help: • Create an effective air barrier due to its superior air sealing capabilities (nearly zero air permeance). • Mitigate the “wind” and “stack effect” by reducing or eliminating air infiltration/leakage from the building envelope (conforms to unusual shapes and fills voids common in building enclosures). • Simplify the air barrier design process (offers “all-in-one” air sealing, thermal insulation, moisture resistance and adhesive properties). • Inhibit mold and mildew growth (minimizes air infiltration that can generate condensation). Note: The U.S. Federal Emergency Management Agency (FEMA) considers ccSPF to be a flood-damage resistant construction and insulation material.1 • Address increasingly stringent air barrier and building/energy conservation codes and standards. • Reduce labor and insurance costs* (since ccSPF is installed in a single operation, it does not require large crews, fasteners, glues or torches). • Qualify* for energy rebates, tax credits and other sustainability/green building designations, such as Leadership in Energy and Environmental Design (LEED) certification or Energy Star® certification. The effectiveness of air barrier systems vary depending on many factors, including the type of assembly, the material choices, the installation quality and how well the system is integrated into the overall building enclosure system. For diagrams of common ccSPF applications, view Honeywell’s document: Closed-Cell Spray Polyurethane Foam Insulation: A Preferred Air Barrier System in Building Envelopes. Additional Benefits of ccSPF Air Barrier Systems Along with the benefits of ccSPF as an air barrier system, it offers many additional advantages as a high quality insulation and air sealing material. For example, ccSPF can help: • Lower energy bills† by improving energy efficiency (air seals and insulates). • Resist heat transfer better than many other insulation materials (R-values† are typically >6.0 per one inch of thickness). • Reduce the load on heating and cooling systems (HVAC sizing can be reduced as much as 35% without the loss of efficiency and comfort).2 • Deliver high structural (racking) strength (adheres to exterior sheathing and studs, adding rigidity). • Resist settling due to its rigidity and stability (some other insulations tend to “settle” or slip down the stud cavity over time). • Increase occupant comfort by reducing drafts. • Absorb sound and reduce noise. • Impede the entry of insects and pests. There are many considerations when designing a building to optimize heating and cooling efficiency, control moisture and provide occupant comfort in all climates. The case for well-designed air barrier systems is strengthening as expectations for improved energy efficiency and building performance grow. Air barriers are systems of materials used to control the unintended movement of air into and out of a building enclosure. A building enclosure includes all “six sides” of a building — exterior walls, roof and foundation floor — and may also include separations within the structure. Although there are many materials that meet minimum criteria for air barriers, closed-cell spray polyurethane foam (ccSPF) offers unique benefits that make it a preferred choice. According to many designers, builders and enclosure specialists, ccSPF is one of the leading materials that helps meet (and in many cases, exceed) air barrier code and performance requirements.

What makes ccSPF so effective? CcSPF insulation is spray-applied on site during new construction or renovations to air seal/ insulate wall cavities, crawl spaces, attics and basements. It can also be used as continuous external insulation for walls and as a roofing system. It is sprayed as a liquid that immediately expands to many times its original volume upon installation. As it expands into foam, it adheres and contours to the spray surface, filling in cracks and crevices that can cause air and water infiltration. Not only can ccSPF help prevent damage during severe weather, it provides excellent insulating and air sealing capabilities which can lower energy costs* and may qualify for rebates and tax credits.

Roof Removal for Commercial Roof Replacement

by on January 9, 2017 in Commercial Roofing, Replacement


Most commercial roof replacement projects require old roof removal as one of the first steps. Tearing off the old roof and replacing it with the new is a fairly common practice. How does roof removal impact the cost of your commercial roof replacement project?

Increased Duration

Roof removal is faster than roof installation (in most cases), but it is still not exactly a fast process. Roof removal takes time and effort, and it can slow your roofing project down by several weeks on large jobs. If you are in a time crunch, you might want to consider options for avoiding roof removal.

roof removal

Tear-off takes time and is expensive. The more of it you do, the more money required.

Increased Labor Costs

While those workers are taking care of the roof removal on your building, they are getting paid. That means increased labor costs for you. You might have 5-10 crewmembers up on your roof working on a non-value-adding task. Roof removal is necessary for some new roof installations, but it doesn’t add value to your building. Do you want to pay higher costs for something that is just a stepping stone and not an actual benefit of the roof?

Roof Removal Produces Waste

When you remove your existing roof to replace it, you can’t reuse those roofing materials. They go in a dumpster, which goes to the landfill. All of this waste produces more material in landfills that are already filling up at a dangerous pace. You have to pay your crew members or a third party to take care of the trash from your building. If there was a way to avoid this, you’d certainly be interested.

Avoiding Roof Removal

Well there is a way to avoid roof removal! A great way, actually. A retrofit roofing system, such as silicone coatings or spray foam, is applied directly to your existing roof with no need for tear-off. This saves you time, money, and reduces the amount of waste going to local landfills. Who wouldn’t at least consider a system that provided all those benefits!


Roof removal is a time-consuming, expensive, wasteful process. Sometimes it is a necessary part of facility management, but in many cases it can be completely avoided. If your system is a candidate for a retrofit roof or a coating restoration, give us a call today! We specialize in minimizing tear-off, saving you money, and helping the environment.

Cost of New Roof Installation

by on January 16, 2017 in Commercial Roof Coatings, Installation


Commercial roof replacement is typically a two-step process. Remove the old roof, then install the new roof. Each step in the process has costs and hurdles associated with it. These costs can vary greatly depending on the size of the roof, the complexity of the roof, and other factors. The cost to install a new commercial roof depends largely on surface prep and the material used. Let’s look at the expected cost of new roof installation below.

New Roof Installation

Prepping the roof for a new roof can be a difficult process.

Surface Prep

Depending on the system you choose, the surface will have to be prepped in various ways. For single-ply roofs, ISO board must be installed to the roof deck prior to installing the single-ply membrane. This adds installation value to the roofing system, but takes additional time and money.

Metal roofs don’t require much prep work. They are many times installed with no installation underneath (which isn’t a good idea, but people do it). Metal roofs are installed directly to the roof deck.

For retrofit systems like spray foam and restoration coatings, prep work consists of cleaning the roof and repairing any major problems. Prep work for these two systems is very simple, like metal, and doesn’t require a lot of time or money.

Material in Use

The other major factor in the cost of new roof installation is the cost of the material you use. Metal panels aren’t extremely expensive, and they lie about in the middle of the road.

Most single-ply materials are less expensive than other systems, and present a great opportunity for saving money to building owners. The purchase of single-ply materials is rarely one with a lot of zeros.

Spray foam roofs offer some of the highest material costs around, because they are an extremely effective roofing material. Foam outperforms most other systems in most categories, and that is reflected in the price of the material. The labor for foam roofs is generally less expensive than metal or single-ply roofs, which allows for some cost recuperation there.

Restoration coatings, whether they be silicone, acrylic, or otherwise, offer less expensive material for roof replacement than all other systems. You simply cannot be the prices offered by restoration coatings, because they are so simple. You need a very thin layer of coating, they can be efficiently manufactured, and there are enough manufacturers that the price is fair. Restoration coatings offer extremely reasonable material costs.


If you’re looking to replace your commercial roof, the new roof installation may be the most expensive part of the project. Don’t overlook the cost of the material as a significant portion of the project, because it is important and can cost you a lot of money. Give us a call today if you’d like to learn more about replacing your commercial roof.

Reduce Installation Duration with Roof Coatings

by  on November 21, 2016  in Acrylic CoatingsInstallationSavings


When you switch from your current roofing system to a silicone restoration system, you can’t help but move faster. There just aren’t too many roofing system available that can be more quickly installed than a silicone roof coating. What does this mean for you and your customers? It means your jobs are completed faster, which saves everyone money and keeps everyone happy. Very few contractors want to work on the same roof for 5 months, and very few building owners want construction crews on their roofs for 5 months. The remedy? A silicone roof coating that can reduce installation time. How does a silicone roof coating reduce the amount of time you spend on the roof?

reduce installation duration

Silicone roof coatings are applied directly to the roof surface with no need for a primer in most cases.

No Primer Required

In 95% of the cases our coatings are applied, no primer is necessary. How? We have developed a coating that is extremely tenacious and can adhere to almost any roof surface. What this means for you is you get a great roof in less time. An acrylic coating that requires a primer will take nearly twice as long as a silicone coating that doesn’t. Instead of coating the roof once, you have to prime it and then coat it with acrylic (not to mention you also have to apply two coats of acrylic).

Only One Coat Will Reduce Installation Duration

As we touched on above, acrylic coatings require a primer, and then two coats of material. This means they have to cover the entire roof surface three times. Our material doesn’t require two coats. In fact, our coating can often restore a roof in only one coat, thanks to its high-build properties. The ability to restore a roof in only one pass, rather than three, saves serious time, which saves serious money.

Less Prep Work

Silicone roof coatings, or roof coatings in general, require some roof surface prep, but not nearly as much as other roofing systems. The decrease in prep work means the project goes more quickly than others. A roof coating typically only needs a tube of caulk and possibly some reinforcing fabric to prep the roof.

No Tear-Off

Perhaps the most significant way roof coatings reduce time spent during installation is by eliminating the need for roof tear-off. Other systems require you to tear-off the old roof system before installing the new one. However, roof coatings are applied directly to the existing roof with no need for tear-off. Another great way to save money by reducing installation duration.


Choosing to use a roof coating on your home will reduce the amount of time you spend installing the new system, which keeps your occupants happy and will save you money. There are other installation benefits to silicone roof coatings not covered here; give us a call to learn about them.

Spray Foam 101 for the Consumer

Spray Polyurethane Foam (SPF) is a durable and high performance plastic insulation.  There are a variety of SPF types including low density insulation (commonly referred to as “open cell”), medium density insulation (commonly referred to as “closed cell”), high density SPF typically used as commercial roofing material, and low pressure “kits and cans” which are typically used for smaller insulation jobs.

Roofing SPF is usually a solution for larger commercial, industrial or apartment properties, managed by a construction professional, and is detailed on the Construction Industry section of the SPFA website.  If you have a residential property with a flat / low-sloped roof, SPF is still a great roofing option for you and you are encouraged to review the information elsewhere on this website.

Although “kits and cans” are less complicated and able to be employed by a knowledgeable user, in almost all cases it is recommended that SPF be installed by a trained, experienced, and skilled professional.  The installation of SPF requires the user to be familiar with installation techniques, product health and safety guidelines, principles of building science and other considerations.

SPF has fantastic primary performance attributes including high R-value, reduction of air and moisture-infiltration, sound attenuation, durability and increased strength of the structure it is installed in or on.  The unique aspect of SPF is that in most cases, this product can deliver all of these performance attributes in one product instead of combining several.  That means fewer opportunities for failure stemming from multiple product dependency, multiple trades working on your project, and from individual component failures.  SPF is a one-stop-shop in most cases for consumers looking for a high performance building solution.  It is a tried and tested product in use since the early 1960s.

SPF is the best solution when access to the installation area is unobstructed.  That means all new commercial/residential construction insulation and roofing, along with attics and crawlspaces in residential renovations (which also happen to be the points where the greatest energy savings can result).  If you are looking to have SPF in the exterior walls of the building envelope for an existing building, SPF makes a great choice if you are planning to undergo a deep and detailed upgrade to the building.

It is widely recognized that SPF is a more detailed installation than some other insulation types, but the list of benefits for SPF over other types is considerable.  Its proper and safe installation calls for knowledge, skills, and abilities possessed by an experienced professional installer.  The product must be installed properly to realize the greatest performance characteristics.

Your home or building is likely your greatest investment and you need to make the right improvement choices for it. SPF should have a great impact upon your property in the way of energy savings, sustainable longevity, performance, value and comfort. But the installation is a skilled craft – despite how easy it may look on a video. Your property is going to temporarily be turned into a manufacturing site for the SPF, and you will be expected to remove yourself, family, and pets from the jobsite until the established re-entry time is past (typically 24 hours).

Additional Consumer Information


With premium performance admittedly comes a premium cost. SPF can be slightly higher in cost than competing inferior insulation and roofing technologies, but your investment is quickly paid-back through exceptional energy cost-savings from the SPF. To further reduce your investment cost, many times federal, state or municipal utilities or efficiency organizations may offer a tax incentive, or other credit for efficiency improvements. Consider the information from these sources and how they may apply to reduce the cost of your project:

Installation, Performance & Benefits

SPF has a multitude of performance benefits. For the consumer SPF brings a high R-value and air-sealing product all-in-one. The product is also known for sound-attenuation within the building, as well as adding “racking strength” to walls and increasing the durability and attachment of roofs when SPF is in the attic under severe weather/wind conditions. The R-value and air-sealing capabilities vary based upon the product and the manufacturer. For example, low-density SPF (or “open cell”) has a comparatively lower R-value per inch and slightly less air-sealing capability than medium-density SPF (or “closed-cell”), but if your project calls for capabilities of low-density SPF the solution could result in some project cost savings. However, if your project calls for a combined vapor, moisture and air-barrier with higher R-values per inch, or the cavity to fill is not large enough for low-density SPF to reach the specified R-value, closed-cell could be your solution. For particularly challenging geometric installations such as an attic, cathedralized ceiling or crawlspace, SPF’s ability to conform to the shape of the surface it is sprayed to is an unrivalled benefit.  Additionally SPF can be delivered through a variety of equipment, ranging from high-pressure professional contractor rigs, to low-pressure “kits & cans” that are designed to satisfy smaller projects. Every product and project will be different so the solutions will be different. It is impossible to predict every scenario where you may want to use SPF as a solution, which is why working with a knowledgeable and experienced contractor is recommended.  The flexibility in use of SPF is one of its greatest attributes.

Energy & Environment

SPF can offer important benefits reducing energy consumption and improving the environment. Energy use reduction from better insulated and air-sealed buildings means less pollution from energy production. But SPF impacts energy and the environment in other positive ways as well. By sealing the building and utilizing your HVAC system for ventilation, the indoor air quality (IAQ) can improve by reducing interior pollution and allergens. Properly installed SPF, which includes use of a vapor barrier, can control the transmission of moisture in the building to reduce the likelihood of mold growth. Plus, SPFA performed a rigorous, third-party ISO-standard compliant Life Cycle Assessment (LCA), and corresponding Environmental Product Declaration (EPD). These documents confirmed what the industry and satisfied customers have always recognized, that SPF has rapid payback and is environmentally conscious from “cradle to grave”. The SPF industry is very proud of the product’s performance, now verified in a way that no other insulation industry has gone to these lengths to produce.

SPF Health and Safety Information

SPF is a polyurethane (plastic) product, along with bowling balls, mattresses, your automobile dashboard and the sole of your sneakers. But SPF is created in your building rather than a factory. It requires a detailed installation process using a variety of materials and equipment operated by a knowledgeable and experienced professional contractor. Once the SPF is properly installed, cured and inert, occupants are able to return following a period of time, typically twenty four hours, having allowed the SPF professionals to complete the installation and ventilate the area.

SPF uses two containers of materials that contain chemicals and additives necessary for the reaction that produces SPF, just as other plastic products require multiple components to be properly manufactured. The installation crews typically wear body suits, hoods, gloves and respirators as required PPE. The reason for this is simple – during the installation process the materials used, by themselves, represent possible respiratory hazards for the installer.

Particularly with professional high-pressure SPF equipment, the type used to insulate rooms or entire buildings, the SPF materials are heated and pushed through hoses to the tip of the gun where the reaction first takes place. The SPF begins to rise before it even hits the wall. Due to the pressure of the SPF some of the material is temporarily aerosolized around the installer, which is the reason for the Personal Protective Equipment (PPE) and mechanical ventilation. This is also the reason why customers are not allowed in the spray area or the building during and soon after the installation process. With the recommended twenty four hours (consult with your contractor for specific manufacturer recommendations) before re-entry, curing is able to take place and ongoing ventilation allows for any odors or vapors to vacate the premises.

The SPF professional should be familiar with these topics and be able to discuss with consumers what the expectations are for the project. If the contractor has completed the SPFA Professional Certification Program (PCP), the basics of essential health and safety are covered even at the entry-level Assistant Certification.

  • Visit SPFA’s Health and Safety page HERE for more information.
  • Visit this partnering website for more information on installation expectations.

In the case of low-pressure “kits and cans” that are typically used by both SPF professionals as well as weatherization professionals or experienced Do-It-Yourselfers (DIY), it is still important that proper precautions are taken, the manufacturers recommendations are followed for use and handling, fans and ventilation are utilized, and PPE is worn. The “low-pressure” at which these systems operate means that the materials coming from the SPF gun or can are not being delivered at the high pressure of professional equipment. However, the material components are similar to high-pressure SPF and users are recommended to wear PPE as well, or hire a professional.

  • For a free instruction video on safe use of low-pressure SPF, click HERE.

SPFA Professional Certification Program

The SPFA Professional Certification Program (PCP) is oriented toward professional contractors, and covers information most-critical to that community. An SPFA PCP Certified Assistant, Installer, Master Installer and Project Manager will have demonstrated their competencies on health, safety, handling and installation of SPF, for either insulation or roofing. Having such an industry credential allows that contractor to differentiate themselves from the competition and adds to the value delivered to the consumer.

The SPFA PCP was created and operates according to rigorous and demanding international ISO—17024 standards. The PCP addresses at various appropriate levels information relating to the health, safety, installation quality, code compliance, building science and other aspects of a professional SPF installation. Passing an active-spraying Field Exam is required at the Master Installer level, and additional requirements and experience declarations are required at various levels.

SPF installation is a typically professional’s job. SPFA hopes that industry credentials such as PCP, among others from related industries, are a useful resource for consumers looking for contractors that have demonstrated their knowledge, skills and abilities in order to achieve these certifications.

  • For more information on SPFA’s PCP Certifications, click HERE.

Fire Performance

Like many building products, SPF is an organic, combustible material, and requires proper treatment to reduce the risk of fire. During installation a professional SPF contractor will typically place a “No Hot-Work” sign after installation before fire protective coverings or coatings are installed. No Hot-Work means that before installation of the protective coatings or coverings, no welding or open flame sources should be near the SPF. Welders, plumbers with soldering torches, and other intense flame-producing activities should proceed cautiously and be certain the SPF is protected from the flames.

Once the SPF is installed, building and fire codes (IBC Section 2603 and IRC Section R316) require that building assemblies using foam plastics, including SPF, must have the same fire performance as assemblies using other building products. Building codes prescriptively require that all foam plastics be separated from the interior space with a 15-minute thermal barrier. This requirement is typically met using ½” gypsum wallboard on walls and ceilings and ¾” plywood on floors. In lieu of these prescriptive coverings, intumescent paints can be used as an alternative thermal barrier, provided that these coatings, when applied over a specific foam product, pass a series of full-scale room corner fire tests.

In certain attic and crawlspaces not regularly accessed or used for storage, the foam must be covered with an ignition barrier. The codes prescribe several ignition barrier materials, and alternatively allow intumescent coatings or even bare foam if the assembly passes a special room corner burn test defined in Appendix X of .International Code Council Evaluation Services (ICC-ES) Acceptance Criteria AC-377. To be sure of the thermal or ignition barriers meet the building code requirements, check with the ICC-ES Evaluation Service Report or other 3rd-party product evaluation reports for details. It should be noted that these limited access attic and crawlspaces still need to be separated from the interior with a 15-minute thermal barrier.

Regardless of the thermal or ignition barrier requirements for the foam used, it should be addressed in the project scope and planning. It is essential that the consumer be aware of which product is being used in their building and ask the contractor for an ICC-ES report is available. In the absence of an ICC-ES report, the contractor should be able to advise the consumer if an ignition or thermal barrier is required for the installation. For more information on fire safety, as well as ignition and thermal barriers for SPF, please review SPFA’s AY-126 guidance document on this topic.

Single-Ply Roofs Aren’t Custom Made

by  on October 31, 2016  in Building MaintenanceInstallation


Do you prefer to purchase things that are “cookie-cutter”, or custom-fitted for you? Whether we’re talking about clothes, a house, a car, or a roof, just about everyone likes to have a little bit of customization on things they own. Whether this means you repaint your house after purchasing it, or put bumper stickers on your car, everyone likes things to be a certain way. When it comes to roofing, it’s harder to get a customized product. However, there are roofing systems out there that are custom-designed for your exact building, and others that are not. Single-ply roofs are manufactured in a factory and every roll is identical, regardless of what your roof looks like. What is the problem with mass-produced roofing products?

Custom made roofs

Most traditional roof systems lead to large amounts of wasted material during installation (and later removal).

Non-Custom Roofs Lead to Waste

When a roofing product isn’t custom-made, it means that every piece has to be fitted to line up on the roof. If there is a skylight, a vent, or a drain, the material has to be cut to form a good seal around these features. Each time the material is cut, there is a little bit left over that cannot be used. These small amounts of waste around every roof feature add up and can lead to serious waste on the project. This means that material that you paid for to go on the roof is actually in the dumpster. Throwing money away like that is hard for most people to stomach.

Non-Custom Roof Take Longer

As we covered hereinstalling a single-ply roof can be slow. This is compounded when you have to custom-cut so many pieces of membrane to go around roof vents, drains, skylights, etc. Just rolling the material out takes a while, add in the customization that takes place on the roof, and now you’ve got a very slow process.


Installing a single-ply roof that isn’t custom made for the building it is being installed on means that your project will take longer and have more waste than a custom-made roof, such as a silicone coating. Call us today to learn more about a custom roofing solution for your building.

Single-Ply Roofing is Slow

by  on October 24, 2016  in InstallationSeamless


With our rapid fire society that works at a break-neck pace, very few people are willing to wait for anything anymore. It’s hard to blame people for being impatient, that’s just the way our society is. When it comes to roofing, this fast-paced expectation holds true. Building owners and facility managers want their roofing project finished quickly, as they should. Their building is exposed, they don’t want it to be that way for a minute longer than it has to be. Contractors want to finish the installation quickly because time is money. The faster they work, the more money they make. So, if everyone wants their roofing project to go quickly, why install a roofing system that goes on slow? Single-ply takes much longer to install than a silicone coating. Let’s look at what makes single-ply installation so slow.

Single-Ply Installation Takes Time

Single-ply roofing membranes are typically manufactured in individual rolls. They are packaged in rolls to allow transportation and loading up on the roof. The problem with these rolls is they all have to be individually rolled out and individually fastened to the roof. This is a very time-consuming process, which no one wants to deal with. Rolling out each piece of single-ply membrane, fastening them down, and adhering this to one another can take a very long time.

A Good Seal Is a Process

When individual rolls of single-ply membrane come together on the surface of the roof, they have to be adhered together to ensure that the roof is waterproof. This can be done with fasteners, glue, a heat welder, or some other less common methods. As you do this, you have to move slowly to ensure that the seams get a proper seal. Again, this is a very time-consuming process. Heat welders move slowly, glue has to be very carefully applied, and everyone knows how difficult it can be to fasten something. Getting a good seal on the membrane can be a very slow process.


Single-ply roofs can offer good protection for your building, though their seams and fasteners concern us. However, even the best single-ply membranes still have to be installed, and that can be an extremely time-consuming process that not everyone is willing to undergo. If you’re looking for a faster solution, give us a call today.

Single-Ply Installation Concerns

by  on October 17, 2016  in SeamlessSilicone Roof Coatings


seamless roofing system such as a silicone roof coating or a spray foam roof offers many benefits that aren’t present in a roofing system with seams, such as single-ply. Single-ply roofs and their seams can’t retain heat as well as a monolithic system. They aren’t as leak-proof as a monolithic roof system. Let’s look at some of the other concerns surrounding single-ply installation and performance, and how they can be overcome with a monolithic system.

Installation Process Takes Much Longer

The single-ply installation process isn’t exactly difficult, but it can be very time consuming. Single-ply material is almost always packaged in rolls that are rolled out on the roof and then fastened, glued, or heat-welded to the next sheet of material. This process inherently takes more time than applying spray foam or a roof coating because there is simply more going on with single-ply. The heat-welding or gluing process just takes a while and slows everything down.

How Silicone Helps

Installing a silicone roof coating is the exact opposite of single-ply – extremely simple and extremely fast. Rather than laying down individual rolls and adhering them to one another, roof coatings can be installed in multiple passes and the material just cures together as if there were no seams, because there aren’t any seams.

single-ply installation concerns

A silicone roof coating is custom-made for your roof on the surface – it fits perfectly.

Single-Ply Roofs Aren’t Custom Made

Single-ply materials are made in a factory in only a few sizes. Different roll widths and different material thickness are about the only choices you get. Any time there is a unique feature on a roof: a drain, a vent, a skylight, the single-ply material has to be cut and modified to go around that feature. This takes significantly more time and creates extra labor to flash in around these features.

How Silicone Helps

In contrast to a single-ply roof, silicone roof coatings are “manufactured on the roof.” Sure, the material is made in a factory and then shipped to the jobsite, but it is not yet in its final state. Once it is fluid-applied on the roof, then the material cures and is “manufactured” in real time. This gives you a custom roof designed specifically for your building.

In addition to the customization of a silicone roof, it also has major benefits around penetrations. If you’ve got a pipe to roof around, simply apply your roof coating to that pipe and tie it in to the rest of the silicone. No cutting, no additional flashing materials, just apply the coating right where you want it.

Single-Ply Installation Produces Waste

Because single-ply roofing materials aren’t custom made to fit your roof, they require you to cut the materials to fit them around flashings, into corners, around skylights, etc. This leads to wasted materials, which is wasted money. Once you’ve cut the membrane, it’s difficult to find other places to use those scraps on the roof. They often are truly just scraps that can’t be used again.

How Silicone Helps

Because silicone roofs are custom made on the surface of your roof, they do not produce waste like other roofing systems such as single-ply. The single-ply installation process is full of waste, while you can use every bit of silicone that you take to the jobsite. The only “waste” comes if you overestimate how much material you need, and if that happens you can just put the lid back on the material and use it later for repairs or another roofing project!


Single-ply installation is rife with pitfalls for you as the building owner. Whether it’s going to drag out your installation process, give you a cookie-cutter roof, or produce waste and waste money, single-ply has serious problems. Most of these problems can be eliminated if you switch instead to a silicone roof coating. Give us a call today to learn about silicone for your roof.
