Roof insulation question
Hello everyone. I live in an 133 year old home that “breaths” lol. I’ve been sealing up as much as I can, and I’m currently going to reframe an addition that was added on in the 1970s because unlike the 133-year-old portion that is still in great shape, the 1970’s workmanship isn’t.
I want to utilize ZIP-R on the walls. The trick is the roof. We would like to put some decking on the roof to walk out on from our second story because the current roof there is almost flat with a membrane. Is there any type of exterior foam I can put on that would hold up to a deck? I won’t be installing a hot tub or anything, just some railings and people.
Any ideas would be great! Thanks so much!
