SPF is Sprayed Polyurethane Foam, 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. SPF can help make your commercial roof leak free and at the same time add exceptional R-value that lowers your energy costs!
Benefits of a Spray Polyurethane Foam Roof
1). 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.
Recommended for application over these surfaces:
- Composite Decking
Life Expectancy of Sprayed Polyurethane Foam Roofs
There 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.
Condensation Concerns of Sprayed Polyurethane Foam Roofs
SPF provides a continuous air barrier preventing moisture through air leakage, minimizing dew point problems and condensation within the building envelope avoiding thermal bridging, resisting heat movement in all directions and providing reliable performance under varying conditions.
SPF roof systems can be applied directly over BUR, modified-bitumen, concrete, wood, asphalt shingles, clay tile, and metal.
Since it adds very little weight (about 8oz. per square foot at 1 inch thick) SPF is used as a recover system over existing roofs without the need for tear-off. This reduces the amount of construction debris in landfills. Also if no tear off is needed, exposing the interior of your building to the elements is eliminated.
Another major advantage in a Sprayed Polyurathane Foam roof system that does not exist with any other roofing system, is the SPF is a renewable system. While BUR and single-ply roofs must be removed and replaced after their usable lives, SPF roofs can be repaired and recoated to offer an indefinite life expectancy coupled with the energy savings and reduction of in house maintenance costs.
The SPF roofing system maintains a tremendous long term cost efficiency advantage over all other roofing systems.
Reduce Cooling Expense by up to 30% and Recoup your Costs
The average roof absorbs a large portion of the sun’s ultraviolet rays as heat. Conklin’s white SPF roofing system reflects 85% of the sun’s heat, cooling your building and saving you as much as 30% in air conditioning costs.
A Great Return on Investment
A great return on investment is another important reason to install Conklin’s SPF Roofing System. Many satisfied building owners discover that a Conklin roof pays for itself during the warranty period in lower air conditioning costs. Federal tax rebates, tax credits and deduction may also offset your investment. Check with your local utility company, tax advisor, or visit www.energystar.gov for additional details.
