  Aluminum Shingles Hamilton, ON Review 🇨🇦 — December 16, 2025 | Interlock®

  Review: December 16, 2025Completion: August 2, 2001

  The roof was installed in 2000 by the previous owner. We had an issue were a couple of the shingles on the peak came off in very high winds, and was fixed quickly. No problems since then (almost 2 years ago now). Also, we removed a chimney for a fireplace (also installed by the previous owner), and needed the resulting hole patched. This was done very nicely and for a reasonable cost. Thank you!

  Standing Seam Hamilton, ON Review 🇨🇦 — June 10, 2021 | Interlock®

  Review: June 10, 2021Completion: May 10, 2021

  I believe that there could have been a little better communication leading up to the scheduled start date of the project to let us know that there were going to be some delays. Also, there were considerable delays in the material delivered to the job site and getting the work crew to the job site as specified. I understand there were certain weather delays at the time. The crew eventually got there and then spent one extremely long day there, working on the project into the night.
