  From the time that we first called with questions about a metal roof until the time our roof was installed and we received our warranty, Interlock Metal Roofing treated us like a valued customer and appreciated our business. The sales and installation teams are awesome and we are very happy with our purchase. Thank you! Jeff and Paula- Oshawa.

  I think the roof had more technology in it then I knew. I think they could've explained that type of explanation better.

  There is on a corner that has a very sharp edge that I'm worried about. They were fast and thorough. They fixed an issue seamlessly.

  Customer service and trying to get a repair scheduled and the company back out to the job site. They delayed the installation after setting the schedule on the initial meeting.
