SPRAY FOAM ROOFING SYSTEMS

Whether you are currently planning new construction or reroofing an existing roof, Spray Polyurethane Foam Roofing and Lapolla White Reflective Coatings are for you. This is because it lends itself well to all types of roofing situations, from traditional flat roofs to unusual designs. Foam roofing systems can be applied rapidly, with little or no disruption to the facilities. In most reroofing situations there is not even a need to remove the existing roof.

Spray Polyurethane Foam has been used as a roofing and insulation material for over 40 years. At one time it was considered to just be an alternative to built-up roofing; foam roofing now protects a wide range of buildings. During this time, foam roofing systems have proven themselves through comprehensive, independent studies to be dependable, long lasting, and very affordable. Today there are foam roofs that have been in place for over 4 decades, and by all appearances they should be able to last indefinitely as long as they are properly maintained.

Replacing an Existing Roofing System

Because of its light weight, Sprayed Polyurethane Foam Roofing can be applied over already existing roof installations. It can be applied directly over asphalt, shingles, built-up roofs, clay tile, concrete, metal, and wood. This saves the need for tear-off, reducing the amount of time, disruption to the business, even the debris in landfills. The roof has to be properly prepared by cleaning off any loose debris and aggregate, and by making sure that it is completely free of moisture.

Repairing a SPF Roof

When a foam roof gets mechanically induced damage from equipment or personnel, repairing the roof can be done easily with a caulking gun. Larger penetrations into the roof can be temporarily sealed with caulking as well, but it is recommended that the contractor should permanently seal the area with a new layer of topcoat.

Polyurethane Foam roofing can sometimes develop blisters, the most common cause of which is due to the presence of moisture. The majority of blisters do not pose a threat to the integrity of the foam roofing system. Unnecessary repair attempts can result in leaks and premature roof problems. If repairs are warranted, it should be left to the roofing contractor to properly repair them.

  • Seamless: Polyurethane foam is applied as a liquid, creating a single monolithic membrane that covers the entire roof. There are no seams or joints, the source of the majority of leaks in traditional roofs.
  • Conforming: The foam can be sprayed onto virtually any surface, irregularly shaped roofs and protrusions are readily taken care of.
  • Lightweight: Foam roofing typically weighs around 50 lbs. per square, versus 800 lbs. for a built-up roof and 100 lbs. for ballasted single-ply roofs.
  • Thermal Insulation: SPF has the best insulating properties available for commercial construction today.
  • Sustainability: Foamed roofs require a minimum of upkeep, creating little waste and have an indefinite lifespan.
