Roof Insulation Hack Needed
I'm helping someone who is living in an RV improve his insulation. It was zero fahrenheit and he is disabled. I think he should live in a house but here we are and that's not my right to make him change.
Currently there is foam board attached roof and sides, exposed to weather. I have used foam poly iso board @ 4" that I could get, finish covering and put a metal roof on. He needs water catchment and wanted to put the elastomeric over the foam roof, somehow creating a slope. I'm opting for metal. What can I do for him so he doesn't freeze?
