Baeumler Approved
Approved contractor profileBuilt for the prairie east of Lethbridge
Coaldale, Taber and Vauxhall sit on open, irrigated prairie, with long sunny summers, summer hailstorms and wind that has little to stop it. Here is what an Interlock® aluminum roof does about each, and where its limits are.
Hail
Insurance Bureau of Canada said in September 2025 that hail had caused about $6 billion of insured damage in Alberta in 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. That does not make them hail-proof: very large hail can dent aluminum, and the material warranty excludes hail larger than 38 mm (1.5 in).
Sun
Taber is known for its corn because of how much sunshine the area gets, and the climate around it is semi-arid. Sun is what fades and dries an asphalt shingle over the years. The Alunar® finish on Interlock panels is covered by the 30 Year Alunar® Coating Warranty, and the aluminum underneath cannot rust.

Wind
On flat, open land a roof takes the wind at full strength, and on asphalt the damage starts at the tabs and the ridge. Interlock panels lock to each other on all four sides with the fasteners covered, and wind resistance is warranted to 193 km/h (120 mph) installed to manufacturer specification.
Permits
In Coaldale, building permits are issued and inspected by Superior Safety Codes, not by the Town office, and some projects need a development permit from the Town as well. Taber, Vauxhall and the Municipal District of Taber set their own requirements. We confirm what your roof needs at your address before the crew starts.

Ice dams
Ice dams form when heat from the house melts snow on the roof and the water freezes again at the cold eaves. That starts in the attic, not in the roofing, and the material warranty excludes ice damming. We look at your insulation and ventilation at the consultation, and plan snow guards where sliding snow would land on a door or a deck.

Coaldale 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
Coaldale roofing from Interlock Metal Roofing (Alberta) Ltd., the certified Interlock® installer for Alberta. This site covers the Town of Coaldale, 11 km east of Lethbridge, and the towns east and north of it: Taber, where Highways 3 and 36 cross, Barnwell, and Vauxhall and Hays to the north. More of our roofs here are in Taber than in Coaldale itself. Interlock Roofing makes the panels in Canada at its plant in Delta, BC; our own crews install them from our Calgary office, and the consultation is on Zoom or at your home.

Why homeowners here choose aluminum
Our crews
Interlock Metal Roofing (Alberta) Ltd. installs every roof with its own crews, working from our Calgary office. Nobody else measures, installs or answers for your Coaldale roof.
Profiles
Slate is on most of the roofs in our job book for Coaldale, Taber and Vauxhall. It comes in nine colours, alongside Cedar Shingle, Shake, Mediterranean Tile and Standing Seam, all made in Canada, on any roof with a slope of 3/12 or more.
Tear-off
A single layer of asphalt can stay under the new roof only if our inspection finds it suitable. Two layers, cedar shakes and shingles, concrete tile and natural slate always come off. The quote says which, in writing.
Farms
On a farm near Taber or Vauxhall the house, shop and outbuildings can share one profile and colour. We price each building as its own line, so they can be done together or over a few seasons.
Warranties
The manufacturer, Interlock Roofing, 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 10 Year Limited Labour Warranty covers the installation.
Price
We measure the roof and inspect the decking and attic where we can reach them. Anything the inspection finds goes into the written price, not onto a later invoice.
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
Lift a panel, feel the weight, see every colour in daylight and ask the people who install it. Come find us at a show near you.
We do: 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.
Check before you start. In Coaldale, Superior Safety Codes issues and inspects building permits, and some projects also need a development permit from the Town. Whether a straight re-roof needs one depends on the work, so we confirm with them for your address. In Taber, Vauxhall and the MD of Taber the local rules apply.
Well, though not without limits. 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. Big enough hail can still mark aluminum; hail over 38 mm (1.5 in) is excluded from the material warranty, and storm damage is claimed through your home insurance. Ask your insurer how it treats an impact-rated roof.

No. Our only office is in Calgary, at 210, 3750 46 Ave SE. The crews travel from there, and the consultation can be on Zoom or at your home.

They are 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. The consultation and written quote are free.
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.
