-- Spray the roof is an energy-efficient flat roofing material that combines the insulation layer of waterproofing the roof. However, spray foam roof, or SPF, require regular maintenance and a complete re-coating every 10 years to maintain the protective layer over the foam. Without the protective layer, the sun's UV rays quickly destroy an SPF roof. It 'best to coat the urethane coating of SPF coverage, instead of cheaper acrylic coating, and add the longest stone granules coating performance.
One thing we should remember that the SPF is a very popular material flat roof in the south, while to the north, is rarely spray foam roof (although I know of at least two large roofing contractor installing SPF roofs Norther United States with great success). Here in New England and have a layer of roofing membrane is the most popular choice for flat roofs.
Another thing you should consider is the situation with the formation of puddles and shape of the SPF roof will handle it. Rubber roofs, for instance, will seep into the stagnant water, while the roof PVC hot air welded seams will remain waterproof. Although it is preferable not to have standing water throughout, in many facilities renewal of the roof, can not help it, so make sure you get a guarantee of standing water in the reputable roofer.
When the spray foam (SPF) was applied to the proper thickness and finish specifications, a protective layer of elastic coating or gravel is used. This protective layer provides a surface weather resistant and durable can be walked on for normal maintenance.http://www.oceansevenroofing.com/Services/Insulation/Insu...
