Polyurethane Spray Foam Roofing
North Central Insulation was one of the first companies in the nation to install polyurethane spray foam roofs and have been doing it for over 45 years. During this time, spray foam roofing systems have proven themselves through comprehensive, independent studies to be dependable, long lasting, and very affordable. Our spray foam roofs that have been in place for decades, and by all appearances they should be able to last indefinitely as long as they are properly maintained.Click Here to view our Spray Foam Roofing FAQs >
Spray foam roofing is a rigid, closed-cell plastic created by a combination of two liquid components, which react in seconds and can be walked on in a matter of minutes. The spray foam locks in every portion of the roof creating a seamless membrane thus eliminating the need for mechanical fasteners — the number one cause of conventional roof leaks. Spray foam can also be applied to vertical surfaces (parapet walls, curbs, pipes etc.) making the seamless coverage self- flashing.
Polyurethane spray foam roofing has many advantages over traditional roofing methods including:
- 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.
- Flexible: 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.
- Repair vs. Replace: Spray Foam Roofing can be applied over most roofing substrates. This application technology offers an option to either re-cover or repair existing roofs. The cost savings is realized by eliminating the construction cost of tearing off the entire roof and closing a facility/building for roof repairs.
- Weather Durability: Wind uplift is the primary cause of wind damage. Over time a traditional roof will be affected by the partial vacuum created by the wind blowing over the edge. This vacuum pushes up on the bottom side of the roof assembly and loosens fasteners, reduces the strength of the adhesion, and makes the roof vulnerable to future gusts of wind. Independent laboratories have performed tests showing that polyurethane foam enhances wind uplift resistance. Polyurethane foam roofs can also be repaired from wind damage much more quickly than a traditional roof.
