In the wake of hurricane season, spray foam insulation is becoming more widely known as a better alternative for insulation. Not only is it a more popular solution than traditional fiber glass insulation, but it is capable of performing many different tasks.
Unfortunately, many have lost their homes or businesses during Hurricane Harvey. Most experienced damage to their homes or buildings. As many are discovering, spray foam insulation is increasingly being used for many jobs, such as an adhesive for rooftops. The spray foam adhesive creates a strong bond between the roof sheathing and structure that helps to protect the roof structure from severe winds.
Spray Foam is applied to the underside (in the attic) in the roof structure where the trusses meet the roof sheathing. Rather than using nails on each point of the sheathing, there is a long strip of spray foam that runs down the entire length of the joist and acts like glue.
In order to prevent water leakage, the spray foam is also applied to the sheathing seams. Typically, a small gap (about 1 inch) is left between the sheathing panels. It is up to the roof shingles to keep water out of the roof. Most of the time, roof shingles or tiles are unable to withstand strong winds, leaving space for water to leak in. With spray foam acting as a barrier, water won’t be able to penetrate.
