The certified Interlock® roofing installer for Alberta
Manufactured at 9969 River Way, Delta, BC

Baeumler Approved
Approved contractor profileBuilt for the badlands and the prairie
Drumheller sits in the badlands of the Red Deer River valley, with a semi-arid climate of hot summers and very cold winters, and the prairie towns around it get the same summer hail as the rest of Alberta. Here is what an Interlock® aluminum roof does about that, and where its limits are.
Heat
Drumheller's climate is semi-arid, with hot summers in the valley. Years of sun and heat dry out and fade asphalt shingles. Interlock panels are aluminum, which cannot rust, with an Alunar® finish covered by the 30 Year Alunar® Coating Warranty.
Source: Wikipedia, Drumheller ↗
Cold
The same valley has very cold winters. Water that gets into a cracked shingle or a cedar shake freezes and opens it further. Aluminum takes up no water, and Interlock panels lock on all four sides with the fasteners covered, with wind resistance 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 the previous 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. Hail can still dent the panels, and the material warranty does not cover hail larger than 38 mm (1.5 in).
Floods
The Town of Drumheller lists eight floods that led to a state of local emergency, from 1915 to 2018, and runs a flood mitigation program to 2028 that includes berms and floodway buyouts. A roof plays no part in flood protection. If your property is affected by the program, tell us at the consultation so the timing of a new roof makes sense.
Permits
The Town of Drumheller requires building permits for most major construction, including renovations, alterations and repairs, and its Safety Codes office answers questions about what a project needs. We confirm with the Town what your roof requires before the crew starts. Hanna, Three Hills and the counties have their own rules.

Drumheller 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
Drumheller roofing from Interlock Metal Roofing (Alberta) Ltd., the certified Interlock® installer for Alberta. Our job book in this part of the province is small and spread out: a few roofs in the Red Deer River valley at Drumheller itself, more in Hanna to the east and in Three Hills in Kneehill County, and one or two each in Trochu, Linden, Carbon, Acme, Swalwell, Morrin, Delia and Rosebud. Every one was installed by our own crews from our Calgary office, and the consultation is on Zoom or at your home. The panels are made in Canada by Interlock Roofing in Delta, BC.
Completed Interlock® roofs in Drumheller and the towns around it, from our job book. Hanna and Three Hills have more than Drumheller itself; each place with three or more has its own page.

Why homeowners here choose aluminum
Our crews
Interlock Metal Roofing (Alberta) Ltd. installs every roof with its own crews, from our office in Calgary. The company that prices your roof is the one that puts it on and answers for it.
Profiles
Slate is on most of the roofs in our job book for Drumheller, Hanna and Three Hills. Cedar Shingle, Shake, Mediterranean Tile and Standing Seam are made as well, in nine colours, all in Canada, for any roof with a slope of 3/12 or more.
Farms
On a farm or acreage in Kneehill County the house, shop and barn can share one profile and colour. Each building is priced on its own line, so they can be done together or over a few seasons.
Tear-off
Cedar shakes and shingles, concrete tile and natural slate are always removed. One layer of asphalt can stay only if our inspection finds it suitable; two cannot. The written quote says which applies.
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 the decking and attic where we can, and give you one price in writing, with anything the inspection finds already in it.
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.
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 first. The Town of Drumheller requires building permits for most major construction, including renovations, alterations and repairs; its permit page does not mention re-roofing either way. We confirm with the Town's Safety Codes office what your roof needs before work starts. Hanna, Three Hills and the counties around them set their own requirements.
It is made for it, but it is not hail-proof. 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. Very large hail can dent aluminum, the material warranty excludes hail larger than 38 mm (1.5 in), and storm damage is a matter for your home insurance. Ask your insurer how it treats an impact-rated roof.
Drumheller and the communities within it, Three Hills, Trochu, Linden, Carbon, Acme and Swalwell, Morrin and Delia, Rosebud, and Hanna to the east. The rest of Southern Alberta is on calgarymetalroofing.com: the same company, the same Calgary office and the same warranties.
Not many, and we would rather say so. Our job book has only a few roofs in Drumheller itself and more in Hanna and Three Hills; the map on this page shows each one. Every one was installed by our own crews, and a new roof here is quoted and installed the same way.
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. 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.
