How Does a Spray Foam Roof Get Installed?

Polyurethane foam and our elastomeric coatings will seal and totally encapsulate your flat roof protecting it from the weather.

Localized repairs are made if required to the roof. It is swept free of debris and sprayed with a layer of foam. Then an acrylic elastomeric coating is sprayed on top to protect the foam.

The result is a totally encapsulated, weather proofed and seamless roof, protected for years to come. You will of course benefit from exceptional insulation as well.

Protrusions are a prime source of trouble. Spray foam self flashes to all protrusions (vents, pipes, etc…) There is no flashing tape or adhesive to peel away. The flashing becomes part of a seamless covering.

A foam roof system can also save you monthly on your monthly utility bills. You will realize the savings almost immediately after we have installed the foam roof system for you.

The Physical Plant Department at Texas A&M University (TAMU) Systems Facilities Planning and Construction department started monitoring their newly applied foam roof systems from 1980 to 1984. The results were astounding. TAMU was able to recover the complete cost of the roof application through energy savings in an average of four and one-half years.

Our experts will inspect your current roofing system for evaluating its integrity for a foam roof. Norris Spray Foam can fix your current flat roof and prepare it for our spray foam roofing system.



The Spray Foam Reroofing Process

A typical spray-applied flat roof system is composed of three parts. First, a layer of rigid spray polyurethane foam is applied. The foam creates a monolithic seal, adding structure and r-value to the existing roof system. The foam is self-flashing and provides a high r-value per thickness of the product applied.

The second step in the system is to apply an elastomeric silicone coating over the foam. The coating is an excellent waterproofing system and provides protection from solar degradation. A base coat of silicone is applied first and then a topcoat.

Thirdly, after the topcoat is applied, a machine is used to spread a granule material which is an added layer of protection.
