Closed cell foam roof install issues
I had closed cell foam applied to my roof. It was supposed to be 3” but it is typically 4” – 6″ or more.
I had had the foam tested and the density was 1.94, 1.86 and 2.16. The open/closed cell content was 66%,54% and 84%. I would guess that the open cell content is going to make the foam not as structurally sound as well as diminished R value.
What’s the best way to determine if the R value is there for the roof?
Would you have the foam replaced or ask for a rebate?
