Customer Reviews

What customers say about Interlock Slate

★★★★★

I like the product and the installation features over standing seam roofing for this application. There was never any third party quality assurance process to check on the installers work as he was working alone with a helper. Is this installed as per the recommendations of the manufacturer - I really cannot comment on that and neither can the sales person. All I have is a warranty piece of paper.

Builders (staff) were excellent to work with. Not sure. We love the looks of our new roof.

Don C. and Janet C.Deep Charcoal Interlock Slate, 2026 · New Minas, NS
★★★★★

The installation was very high quality, and I am happy with the installation and the roof that was provided by Interlock. I think they did everything they could; there is no area for improvement. I am really happy with the service, quality, and workmanship.

★★★★★

Interlock Metal Roofing could improve by providing more status updates. My experience was pretty smooth and straightforward. No one has brought the sign that we are supposed to display, but everything was great.
