What Cornwall homeowners say
“Interlock Metal Roofing could improve their hiring. Interlock Metal Roofing sells roofs and a secondary party installs them. Whoever they hire to install the roofing should be either trained properly or there should be a higher standard held by the secondary group that does the installation.”

See this roof 3 photos · Black Slate“The installation crew that did the job was not impressive. I went up on the roof when they were done, and I had to call them back because it was a terrible job.”
“Fantastic service ... Brad and his team were on time, friendly, professional and extremely quick at installing additional snow guards to the metal roof we had installed a few years ago. Absolutely no issues at all ... these guys are a pleasure to deal with! Positive: Punctuality, Quality, Professionalism Services: Roof installation”
“Have more then one guy doing the install”
“All went as planned. We still need to have the work inspected and are waiting for that inspector to come and confirm all was done properly.”
Roofing in Cornwall: what to plan for
Why Ontario roofs keep getting replaced
Freeze-thaw, summer heat and wind work on asphalt shingles every year: granules loosen, edges curl and tabs lift. An Interlock roof has no granules to lose and no tabs to lift, and its panels lock to each other on all four sides.
The look of slate or cedar, without the weight
Interlock's Slate, Cedar Shingle and Shake profiles keep the look on a century home, a postwar bungalow or a cottage at roughly 2 to 3.5 kg per square metre, a fraction of concrete tile or natural slate.
Snow that slides, where you want it to
Smooth aluminum lets snow slide rather than sit. We plan snow guards over entries, walkways, decks and the driveway at the quote, so it comes off where it should.
One installer, one set of warranties
We install every roof ourselves. The manufacturer's Guardian Lifetime Limited Material Warranty and our 10 year labour warranty come with it, and our service team is in Ontario.
