Flat Area On Roof Spray Foam

Spray on roofs can also be levelled out more easily reducing the collection of water in ponds.

Flat area on roof spray foam.

Spray foam roofing is also known as spray polyurethane foam or spf roofing. The foam will also contract and expand depending on the weather which again reduces cracks. The usual application of spray foam is to repair and re invigorate an existing roof by removing the saturated areas replacing with like materials and then spraying foam over top of the entire roof. Spf roofs can significantly reduce air leakage and heat transfer saving energy otherwise used to heat and cool buildings and thus decreasing greenhouse gas emissions.

However spray foam roofing or spf requires regular maintenance and complete re coating every 10 years to maintain the protective layer over the foam. Spf roofs provide an insulating barrier for low slope and flat roofs for residential and commercial buildings. A spray foam roof should be inspected after any strong storm but a full professional inspection is only required every five years. This construction approach was first used in the 1970s and it has been implemented much more widely since it was first included in the international code council s icc model building code in 2007 irc section 806 4.

With a spray on roof you can fill gaps seams and cracks in your existing roof construction giving you even more protection. It is a strong and lightweight flat roof solution. Most unvented attics incorporate spray polyurethane foam spf on the underside of the roof deck and attic walls.
