  Review: August 7, 2025Completion: July 31, 2025

  Definitely. We saw one of your roofs that had been installed at least 25 years ago, and it still looks great. So, you have a great product and would definitely recommend you to anyone we know is thinking of a metal roof.

  Membrane Welland, ON Review 🇨🇦 — March 8, 2024 | Interlock®

  Review: March 8, 2024Completion: February 22, 2024

  I think they could improve on communication. The cleanup for the second project wasn't an issue. There was just some miscommunication with measurements, etc. However, I am completely happy with the job. It is very well done. It was just getting there was a little difficult.

  So far there have been no problems with the roof. We never did get a promotional poster to put in front of our house.
