SPRAY FOAM ROOFING
Spray Foam Roofing: What You Need To Know
Spray Foam Roofing is installed by spraying polyurethane foam over an existing substrate. Once sprayed, the foam expands over the entire surface of the surface before solidifying into a seamless cover.
Even though this roofing system has been gaining a lot of publicity over the last few years, it has been in existence, and has been used for commercial and residential roofing applications, for decades.
Read on below to learn more about why you should consider spray foam roofing for your commercial roofing project.
With the straightforward spray foam roofing installation process, business owners and managers don’t need to worry about interrupting their operations during the installation period.
The first step in the installation process involves thoroughly cleaning the existing roof substrate, which can be anything, from concrete, asphalt, metal, shingles and wood. After all the contaminants, dust and dirt have been cleaned off the substrate, the polyurethane foam, made by mixing an isocyanate and a resin/polyol, is sprayed onto it.
Once the layer of foam has been installed, a coating, which can be elastromeric or acrylic embedded with granules, is then applied over it. In addition to providing the necessary fire ratings, the coating also facilitates resistance to weather, normal wear and UV light.
To ensure that you get the most out of Spray Foam roofing, it is important to have a qualified and experienced professional handle the installation process.
And with that, the installation of your new roof is complete.
Seamless Roofing Surface
Seams/gaps and penetrations through the roof surface are the main cause of roof leaks. Since the liquid foam used for spray foam roofing expands into cracks, crevices and gaps in the existing substrate creating a seamless roof surface, installing a spray foam roof automatically solves this issue. Furthermore, the contractor handling the installation can also level out the resulting surface to eliminate the likelihood of having water pooling around depressed areas.
This roofing material creates a surface that contracts and expands with the supporting structure as determined by the prevailing outdoor temperatures, eliminating the likelihood of splitting and cracking.
As previously stated, spray foam adheres to a variety of roofing materials; this means that it can be used to create seamless joints where two types of roofing meet. This effectively helps eliminate the ice and water pooling and leakage problems characteristic of such roof areas.
Businesses can make huge energy savings by opting for spray foam commercial roofing. Once it has been properly installed a highly effective moisture, air and thermal barrier is created. This barrier ensures that the material delivers the highest R-value per inch.
During the colder months of the year, the polyurethane layer keeps the cold out while maintaining warm indoor temperatures. During summer, the same layer keeps the heat out, maintaining comfortable indoor temperatures. This effectively helps keep energy consumption associated with the building’s HVAC requirements as low as possible.
Furthermore, it’s important to mention that the air barrier created by this type of roofing plays an essential role in meeting requirements of the applicable building standards and codes.

Throughout its lifetime Spray Foam roofing requires minimal maintenance. With proper maintenance, these roofs can offer reliable service for more than fifty years.
Generally, polyurethane foam roofs should be inspected every six months. In some cases however, depending on the surrounding vegetation, such as trees, an inspection may not be necessary for the first five years after installation.
It is however advisable to have the roof surface inspected after a powerful storm. The debris from the storm may damage the coating or polyurethane layer, necessitating repair.
The roof’s protective coating may also need to be reapplied after a few years depending on the level of wear.
With the above information in mind, you will be able to make an informed decision on whether a Spray Foam roofing is a perfect fit for you and your business.
