On Oct 23 I posted a question about my EPDM roof issues and received some great advice. I had an inspector come out and take a look and he determined there were several problems with my installation and subsequent repairs. I sent a copy of the report to my roofer and he contested basically 3 things. I don’t know who to believe. In short, here are the issues:
- Is 1/2" high density insulation board the industry standard for residential applications and ISO board for commercial?
- Is uncured flashing tape appropriate for edges, splices in the middle of the roof, and top the ridge of the house? My understanding is uncured is for flashings at roof penetrations.
- Contract says .060 mil to was to be applied. The repair (about 50% of the house) used .045 mil because supplier was out of .060. Roofer says .060 mil is designed as a commercial application because of HVAC guys dropping stuff. He adds residential grade .045 mil carries same warranty. If I read Mulehide’s literature correctly, I don’t think that’s the case. What is the industry standard for residential applications?
