The Interlock® Lifetime Roofing System installer for British Columbia

Approved contractor profileBuilt for British Columbia
BC is a coastline, a rainforest, a snow belt and a fire zone, sometimes on the same drive. Here is what an Interlock® aluminum roof does about each.
Salt air
There is no iron in aluminum, so there is nothing to rust. It forms its own thin oxide layer, which re-forms if the surface is scratched. That is why it is the metal for oceanfront homes, island cabins and anywhere the wind carries salt.
Wildfire
Under ASTM E108 a fire classification belongs to an assembly, not a panel. On our roofs Class A is achieved with two layers of GAF VersaShield® over 12 mm (15/32-inch) plywood, and the aluminum itself does not ignite. Ask us to quote the assembly if your home backs onto forest or grassland.
Cool roof
The Alunar® finish uses pigments that reflect much of the sun's near-infrared energy: solar reflectance from 0.25 to 0.55 depending on colour and thermal emittance of 0.84. The Alunar® finish is warranted for 30 years.
Energy
A reflective roof keeps heat out of the attic in summer. Interlock roofs can cut cooling-energy use by up to 25% compared with conventional dark roofing. Actual savings vary with climate, colour, insulation and attic ventilation.
Solar
A solar array lasts 25 to 30 years. Put it on an asphalt roof and 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. Standing Seam takes clamp mounts with no holes drilled; the other profiles use mounting hardware made for metal roofing. At roughly 2 to 3.5 kg per square metre the roof leaves more of the structure's capacity for the array, and your solar installer confirms the framing.
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.
Months of rain, moss, character homes, strata councils and more homes going solar every year.
Nothing in an aluminum panel for moss to root in or water to rot. Cedar softens and asphalt granules trap the debris moss grows in.
The look of cedar shake or slate on an older house, at a fraction of the weight, and paperwork strata councils can approve.
Put the panels up once. The roof under them outlives the array.
From White Rock to West Vancouver: aluminum cannot rust in salt air.

Mountain snow, wet storms off Howe Sound, and homes that back onto forest.
At roughly 2 to 3.5 kg per square metre, the roof leaves the framing's capacity for what it is really there for in Squamish and Whistler: snow.
Class A Fire Rated Available, as a complete assembly, for homes in the wildland-urban interface.
Panels locked on four sides; wind warranted to 193 km/h installed to manufacturer specification.

The collection
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 West Coast cedar roof, with nothing to rot, split or grow moss 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 work
We install the Interlock® aluminum roofing system on BC homes: interlocking panels locked on four sides with the fasteners out of the weather, made in Canada at the Interlock plant in Delta, BC. One company, one warranty, and a local site for each region we serve, so the photos, reviews and install record you see are from your part of the province.
Sea-to-Sky is served right here. Every other region has its own site, with its own photos, reviews and install record. Same company, same crews, same warranty.

The project map
Every pin is a real, completed Interlock® roof with its profile, colour and install year. Zoom in on your street.
Every Interlock® panel we install is manufactured by Interlock Roofing Ltd. at 9969 River Way in Delta, the same address as our office.
Interlock Metal Roofing (BC) Ltd. was founded on July 6, 1983 and is headquartered in Delta. Canadian owned and operated for 43 years.
The finished roof is made in BC and installed in BC. 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 are the certified Interlock® roofing contractor for British Columbia: a Canadian owned and operated BC company, founded July 6, 1983 as Interlock Industries (BC) Ltd., headquartered at 9969 River Way in Delta. We install one roofing system, the Interlock® aluminum roof, made in Canada by Interlock Roofing Ltd. at the same address. We are BBB Accredited with an A+ rating, Baeumler Approved, and a 2026 GuildQuality GuildMaster Award winner.
Six: Slate, Cedar Shingle, Shake, Mediterranean Tile, Standing Seam and Solid Copper. Slate is the most-installed profile in our BC job book, followed by Cedar Shingle and Shake. Every profile needs a minimum 3/12 roof slope. We bring samples to the visit so you can see each one against your house.
Class A Fire Rated Available as a complete assembly. Under ASTM E108 a fire classification belongs to the assembly, not the panel; on our roofs Class A is achieved with two layers of GAF VersaShield® over 12 mm (15/32-inch) plywood. Aluminum itself does not ignite. If you want the Class A assembly, ask for it in your quote, where it is priced as a line item.
Two. The manufacturer, Interlock Roofing Ltd., gives the Guardian Lifetime Limited Material Warranty on the aluminum material and its factory finish. The installer, Interlock Metal Roofing (BC) Ltd., gives a 10 Year Limited Labour Warranty on the workmanship. They are separate documents with separate terms, and you can read both in full before you buy.
It depends on your roof, so we price each house after one free visit instead of publishing a number. The biggest factors are roof area, pitch and complexity (valleys, dormers, skylights and chimneys), what is under the old roof, the profile you choose, and options such as the Class A fire-rated assembly, snow guards or hidden gutters. Steep lots, stratas and island or ferry sites change the logistics too. You get a fixed price in writing, and anything the deck needs goes into that quote, not into a change order later. Call (604) 210-3850 to book the visit.
We take work in Metro Vancouver, the Fraser Valley, Sea-to-Sky, Vancouver Island from Campbell River to Victoria, the Gulf Islands, the Sunshine Coast, the Okanagan and Kamloops. Each region has its own local site with that region's install record and reviews; it is the same company, crews and warranty everywhere. We don't regularly serve northern BC or the Kootenays, but we consider projects there case by case, so call (604) 210-3850 and ask.
Free, no obligation
A free consultation on Zoom (most homeowners choose it) 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.
