I’m a homeowner who recently had a Certainteed Flintlastic roof installed. I cant remember exactly which type of Flintlastic it was, but I’m thinking it was GTS. Whichever type it is, it has a mineral granule top surface, and it was torch applied.
The roofer told me I didn’t need to put any kind of topcoat on it, but here in Arizona it gets very hot in the summer. He also said I couldn’t just put a reflective coating right on it, but that I had to put some kind of emulsion down first.
Basically, I want to put a white elastomeric coating on it to cool things down, but don’t know if I can do that with the roof as it is. Anybody have any idea? Thanks
