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.
