I'm helping out a friend, who is planning to replace the roof on an addition to his mother's house. The roof that we'll be working with is extremely low slope, nearly flat in fact. I went up there today with a 4' level, and measured a 3/4" drop over the 4' length of the level, which translates to 3/16" per foot. A few years back I replaced the roof on a low sloped addition to my home, using the certainteed's flintlastic roofing, a "peel and stick" SBS product. However, my roof was about 2:12, and I'm certain I can't use the same sort of product on something that's as low-pitched as his mom's roof. I was looking into EPDM roofing. Am I correct that EPDM will be acceptable for a roof of this slope? Also, how is EPDM usually purchased (as a custom sized full sheet, or does it come in standard rolls/sizes, etc)? And finally, I've read a few things online that suggest it's a fairly diy friendly product to work with (for someone who is detail oriented and handy, of course). Have others on here found that to be true? The roof is just under 4 squares in size. Thanks.
