FACTS ABOUT SPF SPRAY POLYURETHENAE ROOFING

DEVELOPING A BETTER ROOF WITH APEX

Surveys conducted by Dr. Dean Kashiwagi of the Del E. Web School of Construction at Arizona State University and Dr. Rene Dupuis of the National Roofing Foundation revealed that SPF shows little sign of deterioration even after 30 years. Dr. Kashiwagi is the pioneer of the “Performance Based Procurement System” for buying best performing services/facility systems. Between 1983 and 1996, he surveyed the performance of more than 1,600 SPF roofs, which 97.6% did not leak and 93% had less than 1% deterioration while 55% of those roofs were never maintained.

In the most comprehensive roof survey ever performed by the National Roofing Foundation, Dr. Dupuis evaluated 160 SPF roofs. Dr. Dupuis concluded that SPF roofing systems appear to have a very high degree of sustainability with an indefinite life expectancy when properly maintained with periodic recoating. More than 70% of the roofs were applied over existing roofs. These findings indicate a properly maintained SPF Foam Roof can be expected to last the lifetime of the property.

ARE SPF ROOF SYSTEMS GREEN CONSTRUCTION?

Properly installed SPF roof systems can easily last 20 years or longer without any maintenance. In addition, properly maintained SPF Foam Roof systems can last the life of a property. A SPF roofing system study was performed in 2004 by Michelsen Technologies and involved a life-cycle analysis in five climate areas of the United States. Analysis of evidence led to the conclusion that the average SPF roofing system costs 15% to 50% less to install and maintain than a conventional membrane roof system over a thirty year period. Maintenance re-coating is provided using the APEX | WDG Silicone Restoration Membrane-SRM that is comprised of 95% solids silicone.

PERFECT FOR FIXING BAD ROOFS

Often light- weight foam can be applied over an existing roof-membrane (i.e. the original membrane can be re-used), which prevents landfill waste. According to a 1999 survey by the National Roofing Contractors Association (NRCA), more than 68.5 percent of the low-slope re- roofing market includes tear-off and replacement of the existing roof membrane.

According to the 2010 Roofing Market Forecast by TEGNOS Research for 2011 there is more than 2.5 Billion square feet of low slope and flat roofing structures in America. That means that approximately 1.7 Billion square feet will require tear-off and landfill waste unless we implement a green alternative using spray foam roofing and silicone restoration membranes.

FOAM AS AN INSULATOR

By nature, SPF Foam Roofs are water resistant because the structure is based on millions of tiny closed cells. This closed cell structure also makes the foam an excellent insulator, giving SPF foam an incredible R-Value of 7 per inch. R-Value represents thermal resistance; the higher an R-Value, the more effective an insulator. Spray foam is the highest R-Value insulator on the market. It’s no surprise SPF has often been used to insulate the external fuel tanks of NASA space shuttles to keep them super-cold. Foam roofs provide the insulation that other roof systems lack without additional materials.

MAKE THE RIGHT CHOICE

Owners need to focus attention on the details that matter the most as energy prices increase the cost of operating facilities. APEX offers a unique roof program to fit the budgets of every facility yet sustainable with a positive return in energy savings to pay for the roof system several times during the life cycle of the building. Our seamless roofing is a risk-free guarantee to building owners. Increased structural strength, estimated energy savings and lifetime maintenance plan are all part of the APEX program.
