What is a spray on foam roofing?
Sprayed Polyurethane Foam is fluid applied using plural-component spray equipment to fill cracks and crevices. It then expands approximately 30 times its original liquid volume to form a hard, closed cell, monolithic roof surface.
The Polyurethane Foam dries within seconds after applied to the roof's surface. Its' expansion results in a weather tight roofing membrane that is fully adhered to the substrate. Because polyurethane is lightweight, it adds little additional weight to the structure.
Polyurethane Foam has a history of more than 35 years as a maintainable roofing medium. Polyurethane Foam adds excellent insulation value to the structure, and utility bills can reflect the difference, up to 30%-70% on energy consumption!
Once the SPF has been applied to the proper thickness and finish specifications, protective layers of elastomeric coating and granules are applied. The reason for the elastomeric coating is to protect the foam from the sun. If the foam is exposed to the sun, it can oxidize and wear away. This protective layer produces a durable, weather resistant surface that can be walked on for normal maintenance.
There is no known end to the service life of a properly installed and maintained Spray Foam Roof. If the coating for an SPF roof is properly maintained, then an SPF roof can last a life time. Every ten or fifteen years, depending on the type and amount of coating installed, the roof will need to be cleaned, primed, and recoated. If this is done, then a quality SPF roof could last longer than you!
SPF roof systems should be inspected annually and after events that could cause physical damage. Small (less than 3" diameter) dents, cracks, punctures from dropped tools, and wind driven debris can be repaired with an elastomeric sealant compatible with the SPF and coating system. More extensive damage can be repaired by reapplying SPF and coating.
Typically SPF roof systems are re-coated every 10-15 years, depending on the type and thickness of coating used, and factors specific to the roof (such as wind erosion effects, hail, foot traffic, abuse, etc.) Recoating extends the service life of the SPF roof system.
SPF roofing systems are very cost competitive with other systems, and code compliant. Life Cycle Cost Analysis performed by Michelsen Technologies demonstrated that over a 30 year life span, SPF roof systems cost between 10% and 50% less on average than comparably insulated membrane roof systems. (Averages were based on SPF roof system recoats of every 6, 10 and 15 years. A copy of the Life Cycle report is available from SPFA.)
SPF is water resistant without other coverings, however, the surface of SPF can deteriorate under the sun's ultraviolet (UV) rays. Typically, elastomeric coatings or aggregate coverings are used to protect the SPF against UV radiation.
Yes! The foam we install is a higher dense material, unlike lighter foams such as styrofoam and insulation wall foams. The roof can easily handle normal walking and wear and tear, though it weighs only a few ounces per square foot.
Yes. All of our foam roofs come standard with a 10 year leak free warranty, which covers labor and material. You can upgrade your warranty to a 15 year, or even a 20 year warranty! All of our warranties are fully transferable.
Sprayed Polyurethane Foam (SPF) is commonly used on flat roofs due to the necessity of heat reflection, insulation properties, and energy savings. When you look at the long term benefits of foam roofing, such as the solution for ponding water, renewability, energy savings and waterproofing, then it is clearly the best choice. SPF roofing is becoming increasingly popular in Southern California.
The start up cost and materials are expensive, the equipment is high tech, and many roofing conractors lack the spray foam application experience needed to insure correct installation.
During the hot summer months, on a majority of buildings, heat is convected through the roof. SPF creates a thermal blanket that insulats and shields the roof from infrared rays. The roof never heats up, as the heat is not convected to the inside of the building. This results in lower air conditioning costs. During the winter months, the foam keeps the heat inside the building.
