What customers say about Interlock Slate

★★★★★

Everything was handled very professionally. Nothing comes to mind. None

Wayne and Liz P.Black Interlock Slate, 2026 · Westlock, AB
★★★★★

The installation team took the time to explain everything to us and answer our questions. Their craftsmanship seems excellent. The company was able to squeeze us in at the end of the year on short notice.

Interlock installed my Aluminum roof 13 years ago and did a fantastic job. They have done minor adjustments throughout the years with great skill. I would highly recommend them.

Bonnie R.Colonial Brown Interlock Slate, 2026 · Anchorage, AK
★★★★★

We had an interlock roof installed on our first home almost 20 years ago. We didn't want to replace the roof every 5 -10 years and 20 years later the roof looks just as good as it did the day it was installed. Very happy we went the interlock route.

★★★★★

I had Interlock put on a beautiful red slate roof 17 years ago.The roof still looks beautiful. 5 years ago, I had them also re-roof my garage with the same type of slate.
