Jeremy:
Good question. I am with you in that I prefer that my pitched-roof rain-proofing relies on gravity. This is the concept invented by the first roof thatcher and followed ever since as roofing technology progressed. When I spotted this regressive trend my first question was: What happens when the rafter connection you need falls under a seam in the roofing shingles? This problem alone is a deal killer. I am sure lesser installers will attempt to fill the seam with caulk. Adding to my discomfort is the reality that chemical solutions are not nearly as reliable as gravity. Even the best caulk degrades with time, temperature and UV. Roofing materials crack and become brittle and powdery. Applying the new technology is iffy with a new comp roof and crazy on roofs a year or more old. We will not be using the new flashingless attachments on comp roofs.

I’m interested in what the group has to say about the trend, by the racking manufacturers, away from the use of flashings for asphalt/comp roofs? We have long used SnapNRack flashings with much success. I especially like the fact that the penetrations are fully flashed and do not rely on sealant. I am NOT a fan of their new raised cone/epdm gasket flashing. There are a number of these raised cone flashings in the marketplace and it’s my experience that they don’t hold up to the test of time and I wonder what the roofing manufacturers have to say about this. I see that Unirac, SnapNRack and others are now offering basically a sealed L-Foot which is essentially where we were 15-16yrs ago and met with a lot of opposition from the roofing industry. Just interested to hear what you guys are using these days on asphalt shingle roofs for reliably dry attachments? Best Regards, Jeremy Coxon NABCEP # 091308-21 MWBE Certified
