Metal Shingles Seattle, WA Review 🇺🇸 — September 15, 2023 | Interlock®

The roofing installers did not initially integrate the ice & water shield membrane correctly with the drip edge. I had another roofer prepare the roof deck and put high temp ice & water shield over my whole roof deck ahead of time - a requirement because of my solar panels (and also I think it's a good idea anyway). The ice & water shield wrapped over the edge where the metal fascia was to be installed later. The Interlock installers put the drip edge/starter metal pieces on the edge over the ice & water shield, but they did not put the required strip of additional ice & water shield over the top edge of the starter metal. That is necessary to make sure any water flowing on the surface of the ice & water shield flows over the starter metal and over the drip edge into the gutter rather than under the drip edge and under the fascia. I noticed this after they had already finished two sides, and made sure they did it correctly on the remaining sides of the roof (I had to go to the supplier and get extra ice & water shield for them to use), but it was already too late to correct it on what they'd already done (they would have had to disassemble too much). Of course one would hope no water would ever get to the surface of the ice & water shield, but if we were 100% sure it wouldn't, there'd be no reason for the ice & water shield at all. So, if it's worth it to have ice & water shield, it's worth doing it right.
