Deer Park, Texas -- A Texan insulation company has been called in to repair the roof of a church that had been inadequately protected.
Upon surveying the roof of his church, a representative noticed sun damage and pooling water, although just two years before, an out-of-state contractor insulated the roof with spray foam.
The church roof had sustained damage from Hurricane Ike in 2008 and subsequently had it repaired it with a spray foam roofing system in 2009. After two years had passed, however, the insulation was yellowing due to sun degradation and water continued to pool in one section.
EcoFoam llc of Houston, Texas, won the bid to repair the damage. Before application, EcoFoam had to pressure-wash the dirt and debris off the roof and prime it with Lapolla's Thermo-Prime acrylic roof primer. This process took about a day to complete.
Once prepped, crewmembers focused on applying spray foam to a 500 sq. ft. section of the roof where water had been collecting. To help alleviate this problem, EcoFoam decided to build up spray foam at an angle in order to divert water from the area. They applied Lapolla Foam-LOK 2.8 closed-cell spray foam, spraying about 3 inches of foam and then gradually tapering the application.
Since both the spray foam and the roof needed protection from the sun, EcoFoam applied 80 mils of Lapolla's Thermo-Flex 1000 QS white elastomeric acrylic coating over the entire roof. A major benefit of the coating is that it helps to reflect UV radiation, both protecting the foam as well as keeping the inside of the church cooler. EcoFoam said.
It took four crewmembers about four days to complete the entire project.
