Spray Foam Roofing

Spray foam roofing is an interesting roofing material consisting of two different liquid materials that combine to form a seamless roofing material. After mixing, the foam expands over 20 times to form a complete solid roof. These roofs are popular for the speed in which they can be applied, while providing high performance water resistance and insulation.

Abbreviated SPF, spray foam roofing becomes an adhesive, that will adhere and make a roof on almost any surface except bitumen. This means concrete, cinder block, wood and metal roofs can be covered, which leads to lower costs and less roof waste. Instead of tearing off the old roof and installing a new one SPF can be installed. Spray foam also doubles as insulation further reducing a step required on roofing contractors in Denver. Once sprayed, SPF lasts around 50 years. During that time, it will need occasional maintenance in the form of cleaning and priming.

Sometimes roofing contractors in Denver add UV resistant granules to the top coat of foam to protect it from the sun. Foam is actually pretty hardy. The word foam often turns people off, but the foam is hard and durable. They handle human traffic better than asphalt roofs, but can still be damaged from limbs and tools falling on the roofing surface. However, because it is foam roofing contractors in Denver love SPF for its insulating abilities. A square foot of the substance weighs less than three pounds. This means the rest of that material is insulating air.

In warm climates especially, SPF roofing will pay for itself with reduced energy bills on cooling. Studies show that this roofing material pays for itself in 4-5 years. Few other roofing systems will pay for themselves ever. For the two polymers in the foam to correctly combine, the spraying must be done right. The gun, hose and feeding systems must all operate correctly to install a 1 to 1 ratio of the polymer bases. If something goes wrong, it must be fixed immediately or the project must be stopped. It can be hard for some roofing contractors to do this because this means swallowing the costs of redoing the roof.
