Whether you are designing a building or restoring a flat roof, you need reliable roofing materials to protect the rest of the structure. Spray polyurethane foam (SPF) is a commercial roofing system that offers protection to the exterior of your building, as well as better insulation. If you need a new roof, here are a few reasons to consider purchasing an SPF one. 

Common Questions About SPF Commercial Roofing 

What is SPF roofing? 

SPF roofing is a material sprayed as a liquid that expands into a foam covering across an existing roof. It works to restore the existing roof by covering up any imperfections and offering additional protection from the elements. SPF coats are water- and UV-resistant, which can help slow the degradation of the surface. 

What are the benefits of an SPF roof?

An SPF roof offers additional insulation for your home due to its high R-value. Thanks to the material's foam coating, your roof will be better able to keep your building at the desired temperature since less air can escape. Over time, this can help you save on energy bills since your HVAC system won't have to work as hard. SPF roofs are also renewable because you can simply reapply the spray when it starts wearing out rather than replace the whole roof, though you typically only need to reapply every 10 to 20 years. 

How do I preserve an SPF system? 

You can best preserve the life of your SPF roof by regularly inspecting it twice a year and after harsh weather conditions. When you catch damage immediately, you can resolve it more easily. Sealant and coating can fix small areas of damage, while extensive problems should be repaired by reapplying SPF. Luckily, these systems can last over 40 years when properly maintained and recoated. Additional coats are necessary to extend the roof's life span since they help protect against the UV light that causes SPF to discolor and thin. 

When & where can SPF roofs be applied?

SPF commercial roofing can cover clay, BUR, concrete, shingles, metal, and wood. Because of its variation in thickness levels, you may use it to fill low areas or to add slopes to roofs. Commonly, they are added to roofs in areas with harsh weather environments or for buildings that require additional insulation. SPF can hide the odd shapes of roofing and add slopes where better drainage is needed. It's recommended to complete installation in early spring or late fall to avoid cold temperatures and humidity. The surface also needs to be dry for the SPF to be installed correctly.
