Spray Foam Roofs: A Cost-Effective Roofing Solution

Spray Foam is a proven roofing and insulation system that is lightweight and easy to maintain.  A Spray Foam Roof consists of rigid closed cell sprayed in place foam that quickly forms into a solid, seamless roofing membrane. Combined with a Cool Roof Reflective Coating, the Spray Foam Roof is watertight, provides superior insulating properties and contains the reflective qualities so important to energy efficient roofing systems.

Since Spray Foam Roofs add little weight to existing roof coverings and can build slope to fill in low areas, foam roofs  are frequently used as a re-cover roofing system. If determined advisable, the Spray Foam Roof can be installed directly over most roof decking substrates or existing flat roof as a cost-effective and environmentally friendly  alternative to a complete roof removal.

Seamless Roofing Construction

Spray Foam Roofs provide a seamless monolithic roof system without joints, seams or cracks that would allow moisture, heat or cold to enter the roof membrane.

High R-Value

Spray Foam Roofing has the highest R-Value per inch of any insulating material available. Many of our commercial and residential clients have been surprised at the dramatic improvements a Spray Foam Roof provides, including lowered energy bills, increased comfort, and even sound deadening.


Unlike classic roof systems, which can take several days, or even weeks to install, a Spray Foam Roofing system can be completed in as little as one day, depending on the size of the structure.

Title 24 Cool Roofs

ENERGY STAR® Cool Roof Coatings are installed on all of our new Spray Foam Roof systems as a protective top coat to protect the roof surface and to provide the solar reflectance and thermal emissivity requirements to qualify as a Cool Roof by the Cool Roof Rating Council (CRRC) meeting California’s Title 24 energy standards.
