Spray Foam Roofing Services (SPF Roof Coating)
What is it?
Spray foam roofing, is a process where a material is sprayed as a liquid onto a roof's surface so it can expand into a foam, creating a solid layer across the existing roof. Generally, this is done in a commercial or industrial setting.What are the advantages?
The main advantage of SPF roofing is that it can be used in any climate, and when correctly installed and maintained, can last 50 plus years. It also has a higher R-value meaning a higher ability to resist heat transference, is quickly installed as there is generally little to no tear off required to start, is installed seamlessly preventing leaks and is easy to maintain. A properly installed and maintained SPF roof should not require a recoat for at least 10-20 years.
How do we do it?
SPF roofing is applied using two chemicals for the foam, A (polyol/resin) & B (isocyanate). These chemicals are pumped from separate containers located inside our temperature-controlled trailer and pushed through heated, high-pressure hoses to the specialized spray gun used in the process and sprayed onto the roof.
Are there any disadvantages?
The greatest weakness to SPF roofing is its inability to resist the UV rays. Within 72 hours, uncoated spray foam will begin to deteriorate, which is why our company sprays an acrylic (waterproof) final coating to seal and protect the foam; further prolonging the life of your new roof.
Another disadvantage to SPF is overspray. As with any material the wind will work against us and carry material away from the site as it is sprayed. We work directly with each company so that they can inform all employees of the potential for overspray while we are working and take the necessary precautions to protect their property.
