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.
Reflectance
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.
Energy
Lighter colours absorb less summer sun than dark ones. What that saves depends on climate, colour, insulation and attic ventilation, so we don't quote a figure.
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.

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've worked
From Abbotsford and Mission to Chilliwack, Agassiz and Hope, we install the Interlock® aluminum roofing system on homes, shops and acreages across the valley. The panels are made in Canada at the Interlock plant in Delta, BC.
Completed Interlock® roofs by community, from our job book. Every other part of BC has its own local site: same company, same crews, same warranty.
These are the regions we currently serve. Not sure which one your address falls in? Ask us.

Why this system, in the Fraser Valley
Rain & heat
The valley floor spends much of the winter wet, and the summers run hotter and drier than the coast, especially toward Chilliwack and Hope. Cedar and asphalt age fast under that swing. Aluminum absorbs nothing and cannot rot, and the manufacturer's coating warranty spells out the fade and chalk limits.
Wind
When Arctic air drains out of the interior, the Fraser Canyon funnels it down the valley, and Hope, Agassiz and Chilliwack take the brunt. Interlock panels lock on all four sides with the fasteners concealed. Wind resistance is warranted to 193 km/h (120 mph) installed to manufacturer specification.
Acreages
Plenty of our valley work is on rural homes with outbuildings and long rooflines. The same profiles go on a house, a detached garage or a shop, so everything on the property can match and carry the same system.
Fire
Summers are drier toward the east end, and homes near forest or grassland carry real wildfire exposure. Class A is available on our roofs as a complete assembly (two layers of GAF VersaShield® over 12 mm (15/32-inch) plywood, per ASTM E108), and aluminum does not ignite.
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 by Interlock Roofing 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.
Abbotsford, Mission, Chilliwack, Agassiz, Cultus Lake, Rosedale, Hope and the Fraser Canyon, served from our Delta office. Langley and Aldergrove are at surreyroofing.com, and Maple Ridge at vancouverroofing.com. Same company, same crews and warranty.
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 at the same address. We are BBB Accredited with an A+ rating, Baeumler Approved, and a 2026 GuildQuality GuildMaster Award winner.
Five aluminum profiles (Slate, Cedar Shingle, Shake, Mediterranean Tile and Standing Seam), also available in 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, 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.
Our metal roof cost page shows real price ranges from our own 2025 and 2026 BC contracts, as a rough guide only: prices vary from job to job with the roof's structure and other conditions, and an in-home roof consultation is required for accurate pricing. 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.
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.
