I’m not in the roofing business, but I found the ladder that Interlock Metal Roofing used a bit scary. I had a good experience with Interlock Metal Roofing. They did the garage, and I plan on having them come back to work on the main house next year.

Product vs roof type/style is probably a big part of the homeowner decision making and the conversation about the pros and cons in relation to that. Just a thought!

Metal Shingles Dartmouth, NS Review 🇨🇦 — November 15, 2024 | Interlock®
Review: November 15, 2024Completion: September 19, 2024
There were a lot of nails left around my home and quite a few on my deck. There were sharp pieces of metal that were scattered throughout my yard. I realize there were a lot of materials, and they put down a tarp to try to minimize the debris, but there were still some leftover. I know its impossible to get everything, but there were still some things left around. Their sign has been blowing around my yard, and I would like to know when they are coming back to get that.

Metal Shingles Dartmouth, NS Review 🇨🇦 — December 2, 2023 | Interlock®
Review: December 2, 2023Completion: November 23, 2023
I love the roof and I think the profile is beautiful. They should have probably put down tarps on the ground to collect all the debris, then I think the cleanup would've been easier and better. In our province, we have had a lot of people come from Ukraine because of the war, and I was impressed that they had hired someone from Ukraine. It showed that they were corporate citizens. They are doing their share to help out, I guess. That pleases me when I see things like that.
