Closed-cell spray foam roofing?
I’m finally having the suspended concrete floor sprayed underneath with closed cell foam. It has been a fight to keep the space comfortably heated while the floor would remain around 40 degrees Fahrenheit.
Speaking to the owner of the small company providing this service to me he said he had used closed cell foam on a rusted tin roof he had to seal it. He said he used some type of coating to keep the uv rays from causing it to deteriorate. He said he had done other roofs for locals externally and it seemed to be working well. I’m pretty happy with what he’s done under my floating slab but I’m not sure he’s done the correct thing on these roofs. The big problem where I live is finding people who really do know what they’re talking about. To be honest it’s a hard area for a professional to make a living as it’s a rural area with lower income people.
Ive checked online and found that this is done on flat roofs. I have a flat roofed building that has the rubber membrane and is close to needing replaced. Is this something I should consider doing? I don’t think the fellow I mentioned uses anything special for his roof coatings so I would contact someone else for this service or buy the equipment and start doing it myself.
What do you guys think about this system, it’s pros, cons?
Thanks in advance. Barry
