Spray Polyurethane Foam Roof System
Whether your roof has many protrusions that needed sealed or you’re looking for energy savings from the top down, this is the system for you. With an R Value of 6.5 per square inch and 85% reflectivity this system will pay for itself!
Sprayed Polyurethane Foam (SPF), is a closed cell roofing and insulation material that both water proofs and insulates. Sprayed Polyurethane Foam has the highest R-value of any insulation material which can help make your roof leak free and at the same time add exceptional R-value that lowers your energy costs!
Benefits of a Sprayed Polyurethane Foam System1). Seams are one of the major sources of leaks in roof systems and SPF roofs are totally seamless.
2). Water does not travel laterally in SPF roofs as it can in BUR (Built-up roofs with multiple plies of roof felts laminated together with bitumen) or single-ply roofs. A leak in the top membrane of a BUR or single-ply roof will create the spreading of water, saturating the insulation and causing multiple interior leaks. With SPF, even if a hole is punched through the entire two inch membrane, water movement will be restricted to the hole. In most cases repairs can be made with a tube of caulk.3).Because the SPF roof is lightweight, permeable and fully adhered, normally an old roof does not need to be removed in order to apply a new one. If underlying areas of saturated insulation are found, minimal tear-off may be required.
Life Expectancy of Sprayed Polyurethane Foam RoofsThere are no known end of service life figures for SPF. Generally, if SPF is pressure washed and sprayed with a top coat every 15 to 20 years this system will last decades. SPF shows little sign of deterioration or change in physical properties even after 30 years.
