Approved contractor profileBuilt for Toronto
Ontario is lake-effect snow, freeze-thaw, wind and humid summers, sometimes in the same year. Here is what an Interlock® aluminum roof does about each.
Snow
Interlock panels weigh roughly 2 to 3.5 kg per square metre depending on profile, a fraction of concrete tile. That leaves the structure's capacity for what an Ontario winter puts on it: snow. Smooth aluminum lets snow slide, so we plan snow guards over entries, walkways and the driveway at the quote.
Freeze-thaw
Years of freezing and thawing loosen asphalt granules and curl shingles; cedar takes on water that freezes in the grain. Aluminum absorbs nothing and cannot rust. It forms its own thin oxide layer, which re-forms if the surface is scratched.
Ice dams
Ice dams form when heat escaping into the attic melts snow that refreezes at the cold eaves. No roof covering stops that on its own, and ice damming is excluded from the material warranty. At the estimate we look at insulation and ventilation with you and tell you what we see.
Wind
Interlock panels lock to each other on all four sides, with no exposed fastener for a storm to work at. Wind resistance is warranted to 193 km/h (120 mph) installed to manufacturer specification.
Cool roof
Most Alunar® colours are rated by the Cool Roof Rating Council (CRRC), which publishes each colour's solar reflectance (0.25 to 0.44 when new) and thermal emittance (0.83 to 0.86). Lighter and metallic colours reflect more. The Alunar® finish is warranted for 30 years.
Solar
A solar array lasts 25 to 30 years. On an asphalt roof the panels often have to come off and go back on when the roof wears out underneath them. On an Interlock roof they come off at the end of their own life, not the roof's. Your solar installer confirms the framing and the mounting hardware.

Homes and beyond
The same interlocking aluminum system goes on a family home, a condo or townhouse complex, or a church. We install it across Ontario on:
Antarctica · U.S. National Science Foundation
Interlock® standing seam roofing and Black Diamond siding on six SPOT modules that travel between McMurdo Station and the South Pole, in −51 °C and winds up to 161 km/h. More than 32,000 completed Interlock® roofs across Canada and the USA, and these at the bottom of the world.

Metal roofing Toronto homeowners choose: slate, cedar shingle, shake, Mediterranean tile, standing seam & solid copper
The look belongs to your home. The performance belongs to the metal. Every profile needs a minimum 3/12 roof slope.
A composed silhouette
The formal character of slate at a fraction of the weight, in aluminum that cannot rust.
Familiar warmth
The look of a cedar roof, with nothing to rot, split or take on water in the grain.
Deep shadow lines
Hand-split texture and depth: the usual replacement when a cedar shake roof has had its last re-treatment.
Sculpted, not heavy
The barrel-tile silhouette without the weight of concrete or clay.
Clean lines
Clean vertical lines for a modern home or a cabin, in the same aluminum.
A living metal
Copper weathers over time. Usually a bay, a porch or a turret rather than a whole house.
Where we've worked
We install the Interlock® aluminum roofing system on houses across the City of Toronto: the old city, Scarborough, Etobicoke, North York, East York and York. The aluminum shingles and panels lock on four sides with the fasteners out of the weather. They are made in Canada at the Interlock plant in Delta, BC, and installed by our own Ontario company from our office in Mississauga.

Why aluminum roofing, for Toronto
Thaw and refreeze
Most Toronto winters bring mild stretches that melt the snow before the cold comes back, and the Annex weather station averages 121.5 cm of snow a year (1991–2020 normals). Each thaw and refreeze loosens asphalt granules and lifts shingle edges. Aluminum takes in no water, and Interlock panels lock to each other on all four sides.
Summer heat
Summer days in Toronto can pass 35 °C with high humidity. Most Alunar® colours are rated by the Cool Roof Rating Council, which publishes each colour's solar reflectance; lighter and metallic colours reflect more. What that saves on cooling depends on colour, insulation and ventilation, so we don't promise a number.
Older houses
The old city is known for its bay-and-gable houses, and Victorian and Edwardian homes fill enclaves such as Rosedale. Interlock® Slate and Interlock® Cedar Shingle keep the look of stone or wood on a house like that at roughly 2 to 3.5 kg per square metre, a fraction of the weight of natural slate.
Licensed
Interlock Metal Roofing (Ontario) Ltd. holds City of Toronto Building Renovator Licence T85-3589700. Our office is in Mississauga, not Toronto, and consultations are on Zoom or at your home. The City's permit page says replacing existing roofing material needs no building permit, provided no structural work is required.
Recycled
And the last tear-off your house is likely to need.

The City of Toronto: the old city, Scarborough, Etobicoke, North York, East York and York. Mississauga, Brampton, Vaughan, Markham, Durham Region and the rest of the province are at interlockmetalroofing.ca, the main site of the same company, Interlock Metal Roofing (Ontario) Ltd. The crews and the warranty are the same.
Yes. Four Interlock® profiles are interlocking aluminum shingles: Interlock® Slate, Interlock® Cedar Shingle, Interlock® Shake and Interlock® Mediterranean Tile. We also install Interlock® Standing Seam panels and solid copper. Every profile needs a roof slope of at least 3/12, and we confirm yours at the consultation.
Toronto has a humid continental climate: summers can pass 35 °C with high humidity, and most winters bring mild stretches that melt the snow before it freezes again. The Annex station averages 121.5 cm of snow and 822.7 mm of precipitation a year (1991–2020 normals). Aluminum cannot rust and takes in no water, and Interlock panels are warranted to 193 km/h (120 mph) installed to manufacturer specification.
The City of Toronto lists "replacing existing roofing material provided no structural work is required" among projects that do not require a building permit. If your roof needs structural repairs once the old material is off, that part may need one. We tell you what we find and confirm with the City before that work starts.
Our metal roof cost page shows Ontario price ranges drawn from our completed jobs. Treat them as a rough guide only: prices vary from job to job with roof size, pitch, structural and other conditions. An in-home or Zoom roof consultation is required for accurate pricing, and you get that price in writing.
Ask each one for its City of Toronto licence number, a street address, a fixed price in writing, the warranty document itself, and finished roofs nearby that you can go and see. Our answers: Building Renovator Licence T85-3589700, an office at 2800 Argentia Rd #5 in Mississauga, Interlock® roofs installed in Ontario since 1998, BBB Accredited with an A+ rating, Baeumler Approved, and every Toronto roof counted on this page and pinned on our project map.
Best Roof® is a registered trademark of I.E.L. Manufacturing Ltd., the Interlock company that owns the brand, and it is the name we give the Interlock® roof in Canada. "Toronto's Best Roof®" is the same Interlock® aluminum roof, installed here by our own Ontario company. It is a brand name, not a ranking.
Free, no obligation
A free consultation on Zoom or at your home: we go through profiles and colours with you, measure the roof, and give you a fixed price in writing. No pressure, and an honest date for the install.
