The Interlock® Lifetime Roofing System installer for British Columbia
Manufactured at 9969 River Way, Delta, BC
GuildQuality GuildMaster Award for service excellence
Better Business Bureau rating
Baeumler Approved
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.
Coastline: Province of British Columbia, Coastal Marine Strategy ↗ gives "more than 26,000 kilometres"; federal mapping gives 25,725 km. Product figures are the manufacturer's: interlockroofing.com ↗
Homes and beyond
The same interlocking aluminum system goes on a family home, a strata complex or a church. We install it across British Columbia on:
Antarctica · U.S. National Science Foundation
Interlock® standing seam roofing and Black Diamond siding on six SPOT modules that travel between McMurdo Station and the South Pole, in −51 °C and winds up to 161 km/h. More than 32,000 completed Interlock® roofs across Canada and the USA, and these at the bottom of the world.

Summerland aluminum 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 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
We install Interlock® aluminum roofs across Summerland, from Lower Town, the original townsite, to Trout Creek, Prairie Valley and the downtown on Siwash Flat. Every roof is made in Canada at the Interlock plant in Delta, BC, and installed by our own crews.
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 aluminum roofing, for Summerland
Wildfire
The Bald Range wildfire led to the evacuation of the whole District in August 2026. Where a home backs onto grassland or forest, ask us to quote Class A Fire Rated Available, as a complete assembly; aluminum does not ignite. No roof is fireproof, and embers reach gutters and vents, so we go over the roof edges with you.
Sun
Summerland's Environment Canada station (1981–2010 normals) averages 336.7 mm of precipitation a year and a July high of 28.4 °C; the record is 44.7 °C. A roof here is worn by sun more than rain. Aluminum has nothing in it for heat to dry out, crack or curl.
Snow
The same station averages 54.0 cm of snow a year. On a metal roof, snow lets go in one slide instead of melting in place. We decide at the estimate where snow guards go, usually over entries, decks and the driveway.
Old & new
Upper Trout Creek was settled in 1892 and Summerland was incorporated in 1906, so houses range from the oldest streets to new builds on the benches. Interlock® Slate and Interlock® Cedar Shingle suit an older house; Interlock® Standing Seam suits a modern one.
Recycled
And the last tear-off your house is likely to need.

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.
Straight answers
The District of Summerland: Lower Town, downtown (West Summerland), Trout Creek, Prairie Valley, Balcomo, Mineola and the rest of the benches. Peachland, Penticton, Naramata and the rest of the Okanagan and Shuswap are covered at okanaganroofing.com. One company does all of it, with the same crews and warranty.
Yes. We install Interlock® Slate, Interlock® Cedar Shingle, Interlock® Shake and Interlock® Mediterranean Tile, all interlocking aluminum shingles, plus Interlock® Standing Seam and solid copper. The roof slope must be at least 3/12. We remove the old roof first; we don't patch or install asphalt.
Aluminum does not ignite, and Class A Fire Rated Available, as a complete assembly, is offered on these roofs. No roof is fireproof, and a roof is only one part of a house's exposure to embers. The District has offered free FireSmart Home Assessments to Summerland homeowners, which look at the whole property.
The District of Summerland issues building permits. Its building-permit page says permits are usually required for new building or renovation projects, and lists non-structural maintenance or minor repairs to the exterior of a home among work that doesn't need one. It does not mention re-roofing by name, so we confirm with the District for your address.
Price ranges by profile, from our own BC contracts, are on our metal roof cost page. Treat them as a rough guide only: each roof's structure and other conditions move the price. A roof consultation, on Zoom or at your home, gives you an accurate written price.
I.E.L. Manufacturing Ltd., which holds the Interlock trademarks, registered Best Roof® as a trademark. In Canada it is the name of the Interlock® roof. "Summerland's Best Roof®" is that same aluminum roof, installed in Summerland by Interlock Metal Roofing (BC) Ltd. The phrase names a product; it does not rank anyone.
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.
