That was with the old system that was nailed to the roof, new systems are stapled to the rafters and Florida Roofing and Florida Energy audits showed no danger to any roofing material. When radiant barrier was properly installed by a certified insulation company. Abshire in TV is certified. I trusted my builder. What do you think of Radiant barrier? His answer I Love it it is my home and most green homes now built. Question why does the villages not allow it in a new construction. Answer- Can't make the huge mark up they used to do it. If radiant was bad you would not see it promoted on out Seco Energy Web Site.
