Pittsburgh, Pennsylvania -- The 96 mph winds of Hurricane Ike tore 70 percent of the roof off Steve Villareal's home in Texas City, Texas, more than a year ago. "Damage to my roof was extensive," Villarreal said, and as a short-term solution he put blue tarpaulins on his roof and start cleaning up.
Then Robert Guillory, owner of Lake Charles, Loiusiana-based Elite Services, and a certified BaySystems contractor, who was working in the area, noticed Villarreal's damaged home. Guillory called Lorena Polazzi of BaySystems to ask about the free roof inspections that BaySystems was offering for homeowners affected by Hurricane Ike. Villarreal, his wife and their three children aged 2, 4 and 16 were, not surprisingly, keen to get their roof back
Polazzi coordinated a donation of Bayseal CC, a closed-cell spray polyurethane foam, to the Villarreals. "By using the Bayseal spray polyurethane foam, we were able to not only help this family get a roof back over their heads, but also create a more energy efficient building envelope system," Polazzi said. "Steve couldn't believe we were going to do it for free."
Guillory and his team sprayed under the roof deck with the closed-cell foam, which helps to eliminate air leaks, provide moisture and wind resistance, and reduce sound transmission. The tarps came down, and the Villarreal family not only got their roof back, but also a healthier, more comfortable home.
The method also improves energy efficiency, "so the Villarreal's air conditioner won't have to work as hard," - valuable in a climate where the summer heat can be blistering, Villarreal said.
Closed-cell spray polyurethane foam (SPF) is also classified by the Federal Emergency Management Agency (FEMA) as "highly resistant to floodwater damage."
Other advantages of SPF insulation include
• Expands and fills cracks when applied, virtually sealing a home from moisture and air leakage.
• Cures in seconds, forming the foundation of a structurally strong, virtually airtight, thermal, sound and condensation barrier.
• Adds structural strength to the building. Independent tests showed spray polyurethane foam provides resistance to shearing and racking events such as hurricanes and other strong wind situations.
• Reduces chance of mould growth.
