Roofing in St. Thomas: 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.
