-Extends life of existing roof

-Stops leaks with superior waterproofing

-Lower utility expenses with a "cool" white roof

-Closed-cell foam stops lateral water seepage

-Renewability reduces life-cycle costs

-Seamless Monolithic Roof​​

Spray foam roofs have become extremely popular during the last couple of years, especially amongst people who want to pave way for a more eco-sustainable future.  It is a premium quality and high-performance product, which is why more and more people are now opting for it. 

Myth #3: You Won't Be Able To Walk on a Foam Roof

​That is NOT true.  You can walk on a spray foam roof because it can hold the weight of a person.  You are advised to avoid wearing heels on the roof, as it can damage the foam and can result in a leak.  

Myth #5: It is Not Durable

​Again, this is not true because spray foam roofs have stood the test of time by staying intact

What is Spray Polyurethane Foam Roofing?

​Spray Foam Insulation is a specially prepared fluid that expands once sprayed into position.  It tends to expand up to 100 times its volume when expanded and is known for its superior thermal capabilities.  The difference between materials used in spray foam insulation and other types of foam is that it helps in retaining breathability.  This process is scientifically referred to as water vapor permeability.  This is important because it keeps problems such as mold infestation at bay by not allowing vapors to condense.  

Myth #2: Bird Pick on Spray Foam Roof

​Birds will pick on spray foam roofs IF you have a deteriorating foam roof  that has a lot of exposed foam.  One way in which you can keep your new roof protected is through applying a layer of silicone coating.  It helps seal any exposed areas.

Myth #4: It is Expensive

​It is a myth because it cost the same as a ply roof.  The prices of asphalt and BUR roofs are at an all time high because of the increase in oil prices, whereas the cost of foam roofing has remained constant.

Facts About Spray Polyurethane Foam Roofing

Spray Polyurethane Foam has been used as a roofing and insulation materials for over 45 years. During this time, foam roofing systems have proven themselves through comprehensive, independent studies to be dependable, long lasting and very affordable.  Today there are foam roofs that have been in place for decades, and by all appearances they should be able to last indefinitely as long as they are properly maintained. 

Sprayed Polyurethane Foam is a combination of isocyanate and polyol.  These two components are fed through a proportioner which heats then pumps the two separate components to the spray gun, where they are mixed and sprayed into the substrate.  Because it is sprayed onto the roof as a liquid, it forms a single continuous structure that is seamless and very stable.  SPF requires a clean surface for proper application.  It must be dry, free of contaminants like oil and properly fastened to the substrate in accordance with the proper building codes.  A protective elastomeric top coat is required which is typically sprayed on as well, but it is also possible to be applied with hand or power rollers.

Foam roofing has many advantages over traditional roofing methods.

  • Seamless: ​Polyurethane foam is applied as a liquid, creating a single monolithic membrane that covers the entire roof.  There are no seams or joints, the source of the majority of leaks in traditional roofs.
  • ​Flexible: ​The foam can be sprayed onto virtually any surface, irregularly shaped roofs and protrusions are readily taken care of.
  • Lightweight: ​Foam roofing typically weighs around 50 lbs. per square, versus 800 lbs. for a built up roof and 100 lbs. for a ballasted single ply roofs.
  • ​Thermal Insulation: ​SPF has the best insulating properties available for commercial construction today.
  • ​Sustainability: ​ Foamed roofs require a minimum of upkeep, creating little waste and have an indefinite lifespan.

SPF's Waterproofing Ability

Spray Polyurethane Foam is perfect for many different waterproofing applications.  Because it is composed of billions of closed cells, the foam acts as an air barrier, preventing moisture infiltration into the building.  This ability minimizes dew point problems, which unchecked leads to water condensation inside of the structure.  Moisture infiltration into the building envelope is the number one cause of building deterioration.  

Even when the top coat of a foam roofing system is damaged, the underlying foam will keep the roof from leaking.  The Superdome in New Orleans was damaged once in a severe hail storm.  Thousands of hairline cracks appeared in the top coat, but no leaks ever occurred, even though it wasn't repaired for over a decade! 

If a penetration does occur all the way through the foam layers, the water infiltration will be isolated only to the area where the membrane has been penetrated.  Small penetrations in foam roofing systems can be repaired easily with an elastomeric caulk, reinstating the integrity of the system.

Water ponding is quite often a problem with conventional roofing systems.  When applying the polyurethane foam in reroofing situations, it is very easy to build up areas of greater thickness while spraying, so that water can drain properly.  This also eliminates the problem of additional weight load associated with water accumulation.

Myths About Spray Polyurethane Foam Roofing

Myth #1: Foam Roofing is New

​That is partially true.  Polyurethane foam was done by Otto Bayer in the year 1937, but it became commercially available in 1952.  Once they hit the market, they became increasingly popular by 1960s.  They were being used for industrial insulation projects as well as for refrigeration.  By the 1970s, they were being used for exterior roofing applications.  So, if we do the math, it can be safely concluded that foam roofing has been around for at least 50 years. 

Insulation Properties of SPF Systems

​Sprayed polyurethane foam has an R-Value of 7.14 per inch thickness, enabling it to provide more thermal resistance with less material than any other type of roofing insulation.

Foam roofing produces energy savings of 30% or greater when compared to the alternative roofing systems.  The cost of the roof can be easily recovered in under 5 years, simply through these energy savings alone!
