Thanks to those who convinced me to go with EPDM on my 2/12 roof. Next question: what are the key specs to look for in a quality job? Here’s what I (think) I know so far:
- 0.060 membrane
- fully adhered with solvent-based adhesive
- isocyanurate substrate (are there other options? Is this a generic name?)
- use termination bar to anchor edges
Any special considerations for penetration points for venting?
Any rubber brand better than others? The guy I’m talking to uses RPI
This is the back side of a 24x36 cape. The back is a full dormer with 2/12 slope. On one side an addition roof with a 12/12 pitch butts up (about 1/2 way along 2/12 edge). Addition wall rises above 2/12 and is vinyl-sided.
Any advice appreciated
