What is Spray Foam Roofing?

spray foam roofing diagramSpray Polyurethane Foam Roofing or Spray Foam Roofing is a roofing method in which the polyurethane material is sprayed as a liquid onto an existing roof, allowing it to expand as a foam and create a solid layer across the entire surface. Spray foam roofing can be used to solve your commercial buildings toughest challenges, inside and out. A protective surfacing is then applied to the foam to provide protection from the elements that would otherwise degrade it over time.

SPF Roofing is unique in its ability to provide a seamless monolithic layer of insulation. SPF roofs create little to no waste during their lifetime and also provide waterproof protection when an elastomeric topcoat is applied. The fact that SPF Roofs are sprayed on gives the applicators the ability to have a concise and custom fit for almost all roofs and structures.

 

How It Works

Spray Polyurethane Foam is the most cost-effective and sustainable roofing, insulation, and waterproofing system available in today’s roofing market. With a combination of isocyanate and polyol, these 2 components are fed through a proportioner which heats and then pumps the 2 separate components to the spray gun. At this point in the process they are mixed and sprayed onto the structure. Due to its nature as a liquid, SPF forms a single continuous structure that is seamless and stable once applied to the roof.

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 Polyurea top coat is required, which is typically applied with the Robotic Spray Unit or by hand.

 

Selection of Elastomeric Coatings to Topcoat SPF Roof

Spray Polyurethane Foam’s closed cell structure is water resistant but must be protected with a covering to prevent surface degradation caused by UV exposure. The deterioration caused by UV can be upwards of ⅛ of an inch per year, making the elastomeric topcoat an essential part to the process.
