What Thornhill homeowners say
“Good looking roof. We get compliments from neighbors and a piece of mind. Cleanup.”
“I don't know other than lowering the price, but it is a high-class product for a high-class price.”
“They could have improved on the start date.”
“I really liked Interlock Roofing but I am not close to a decision because my house was a victim of the recent windstorm. I was really impressed with them but I cannot make a decision till I hear from my insurance agent.”
“We assume that they did a good job based on what we can see. We only hope that the areas that are outside of visual range are just as good. It would be great if a manager stopped by to inspect the installers work, since we can't actually go up on to the roof to check for ourselves.”
“I think everything was pretty much right on schedule. We're very happy with the roofing. It was pretty expensive but it's worth it in the long run because it costs the same as if I had my roof done twice with regular shingles.”
Roofing in Thornhill: 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.
