Spray polyurethane foam (SPF) roofing has had a long history of success for the past 40 plus years. This type of roofing substrate offers excellent waterproofing capabilities, insulation values, reflectivity, lower energy costs, lengthen roof lifespan with lowered roof maintenance, and custom tailored slope to accommodate your roofs’ particular needs.
The SPF is a two-component system of polymeric isocyanate "A-Component" and a water/Enovate 3000 (HCFC-245fa) blown "B-Component” which is spray applied onto the roof allowing roofing contractors to form custom slopes, to guide water to run into proper drainage areas, eliminating any ponded water issues. The spray application not only fills low spots on the roof but also fills gaps around roof penetrations and transitions for superior waterproofing.
SPF roofs (newly constructed and restoration projects) require the protection of a roof coating to shield the foam from early degradation. National Coatings offers several different coatings that provide superior reflectivity to block the suns UV rays from damaging the foam, allowing the SPF roofing system to properly function for a long time. The capability to reflect the sun’s heat away from the building also keeps the inside of the building at a cooler air temperature, allowing you to save money on air conditioning cooling costs.
