The certified Interlock® roofing installer for Alberta
Manufactured at 9969 River Way, Delta, BC
GuildQuality GuildMaster Award for service excellence
Better Business Bureau rating
Baeumler Approved
Approved contractor profileBuilt for Highway 2 weather
Nanton, Stavely and Claresholm sit on the open prairie along Highway 2, close enough to the mountains for chinooks and in the path of Alberta's summer hail. Here is what an Interlock® aluminum roof does about that, and where its limits are.
Chinooks
Along this stretch of Highway 2, chinook winds can take the temperature from well below freezing to well above it within hours, then the cold returns. Snow on the roof melts and freezes again, and gusts work at shingle tabs. The panels interlock along every edge, the fasteners sit out of sight, and wind resistance is warranted to 193 km/h (120 mph) installed to manufacturer specification.

Hail
Insurance Bureau of Canada said in September 2025 that hail had caused about $6 billion of insured damage in Alberta over five years. Interlock's Slate, Shake, Cedar Shingle and Mediterranean Tile aluminum panels carry a UL 2218 Class 4 impact rating, listed by Intertek under Delta Building Products. The rating has limits: hail can still dent aluminum, and stones over 38 mm (1.5 in) fall outside the material warranty.
Permits
The Town of Nanton forwards safety codes applications to Superior Safety Codes Inc. in Lethbridge, and building permits have to be in place before renovation work starts. A development permit from the Town is a separate thing. Whether a re-roof needs either depends on the work, so we confirm it for your address; Stavely and Claresholm set their own requirements.
Ice dams
Ice dams form when heat from the house melts snow on the roof and the meltwater refreezes at the eaves. The material warranty excludes ice damming. We look at attic insulation and ventilation with you, and put snow guards where sliding snow would come down on a door, a deck or a car.
Older roofs
Cedar shakes and shingles, concrete tile and natural slate are always removed before an Interlock roof goes on. A single layer of asphalt can stay only if our inspection finds it suitable. The quote says which applies, in writing.

See this roof 1 photo · Black SlateNanton roofing profiles: 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
Nanton roofing from Interlock Metal Roofing (Alberta) Ltd., the certified Interlock® installer for Alberta. This site covers three towns on Highway 2 in the Municipal District of Willow Creek: Nanton, where Highway 533 meets Highway 2, and Stavely and Claresholm to the south. Our job book here is small, and every roof in it was installed by our own crews from our Calgary office. The panels are made in Canada by Interlock Roofing in Delta, BC; the consultation is on Zoom or at your home.

Why homeowners here choose aluminum
Our crews
Interlock Metal Roofing (Alberta) Ltd. installs every roof itself, working from our Calgary office. The company that prices your Nanton roof is the company that puts it on and stands behind the work.
Profiles
Most of the Nanton roofs in our job book are Slate. Cedar Shingle, Shake, Mediterranean Tile and Standing Seam are also made, in nine colours, all in Canada. Each one goes on roofs pitched 3/12 or steeper.
Acreages
On an acreage near Nanton or Stavely the house, garage and barn can share one profile and colour. Each building is measured and priced separately, so the roofs can be done together or one at a time.
Weight
The panels weigh roughly 2 to 3.5 kg per square metre, a fraction of concrete tile, so an older town house or farmhouse can take them. We still check the deck and rafters at the inspection.
Warranties
Interlock Roofing, the manufacturer, gives the Guardian Lifetime Limited Material Warranty on the aluminum and its finish for as long as the original purchaser owns the home, transferable once, workmanship excluded. Our own 10 Year Limited Labour Warranty covers the installation.
Price
We measure the roof, inspect what we can reach, and give you one fixed price in writing. Anything the inspection finds is in that price before you sign.
Recycled
And the last tear-off your house is likely to need.
The metallurgy, coatings and test reports are the manufacturer's to explain: interlockroofing.com ↗
Every Interlock® panel we install is manufactured in Canada by Interlock Roofing at its plant at 9969 River Way in Delta, BC.
Interlock Metal Roofing (Alberta) Ltd. was founded in 1999 and is based in Calgary, with one office serving Calgary, Edmonton and the rest of Alberta. Canadian owned and operated for 27 years.
The roof is made in Canada and installed in Alberta by our own company. It never crosses a border on its way to your home.
Upcoming shows

Interlock Metal Roofing (Alberta) Ltd., the certified Interlock® roofing contractor for Alberta, founded in 1999 and based in Calgary. Our own crews install every roof. The panels are made in Canada by Interlock Roofing at its plant in Delta, BC. We are BBB Accredited with an A+ rating, Baeumler Approved, and a 2026 GuildQuality GuildMaster Award winner.
Ask before work starts. In Nanton, safety codes applications go through the Town office to Superior Safety Codes Inc. in Lethbridge, and building permits must be in place before renovation work begins. Whether a straight re-roof needs one depends on the work, for example if decking or rafters have to be rebuilt. We confirm it for your address. Stavely and Claresholm have their own requirements.
It is built for both, within limits. Wind resistance is warranted to 193 km/h (120 mph) installed to manufacturer specification. Interlock's Slate, Shake, Cedar Shingle and Mediterranean Tile panels carry a UL 2218 Class 4 impact rating, listed by Intertek under Delta Building Products. No roof is hail-proof: the material warranty excludes hail larger than 38 mm (1.5 in), and storm damage is a matter for your home insurance.

No. Our only office is in Calgary, at 210, 3750 46 Ave SE, and our crews travel from there. The consultation can be on Zoom or at your home.
Our cost page shows real contract prices from the Interlock® roofs we signed in the Calgary & Southern Alberta market in 2025 and 2026. Treat them as a rough guide only: prices vary from job to job with structural and other conditions, and an in-home roof consultation is required for an accurate price.
