Built for British Columbia

More than 25,000 km of coastline. A roof that cannot rust.

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

Aluminum cannot rust

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

Class A Fire Rated Available, as a complete assembly

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

Reflects the sun in every colour, not only white

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 cooler attic, a smaller cooling bill

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

The roof to put solar on

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

Locked on four sides

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.

What matters where you live

Mountain snow, wet storms off Howe Sound, and homes that back onto forest.

Light under mountain snow

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.

Forest at the back fence

Class A Fire Rated Available, as a complete assembly, for homes in the wildland-urban interface.

Storms off the water

Panels locked on four sides; wind warranted to 193 km/h installed to manufacturer specification.

Snow where you want it

We plan snow guards over entries, walkways and the driveway at the quote.

Straight answers

What BC homeowners ask us first.

All of our answers ↗

Who is Interlock Metal Roofing (BC) Ltd.?

We install the Interlock® Lifetime Roofing System, which is made in Canada by Interlock Roofing Ltd. at the same Delta address. BBB Accredited (A+) and Baeumler Approved.

Is the roof really made in Canada?

Yes. Interlock® panels are manufactured by Interlock Roofing Ltd. in Delta, BC, and installed by us, a BC company. The finished roof is made in BC and installed in BC; it never crosses a border on its way to your home.

Which parts of BC do you install in?

This site covers Sea-to-Sky and is the hub for Interlock Metal Roofing (BC) Ltd. Every other region has its own local site with that region's install record: Metro Vancouver, Surrey & South of the Fraser, North Shore, Fraser Valley, Greater Victoria, Vancouver Island, Gulf Islands, Sunshine Coast, Okanagan & Shuswap, Kamloops & Thompson. Same company, same crews and warranty.

What profiles can I choose from?

Cedar Shingle, Shake, Slate, Mediterranean Tile, Standing Seam and Solid Copper. Every profile needs a minimum 3/12 roof slope. We bring samples and colours to the visit.

What does the warranty cover?

The manufacturer's Guardian Lifetime Limited Material Warranty covers the material and its finish for as long as the original purchaser owns the home. It transfers once, to the next owner. Workmanship is covered separately by us, in writing, in your contract. Read the full terms before you sign.

How does it handle BC wind and rain?

Interlock panels lock to each other on all four sides with the fasteners concealed, and wind resistance is warranted to 193 km/h (120 mph) when installed to manufacturer specification. Aluminum absorbs no water and cannot rot, so months of coastal rain do not soften it. Valleys and gutters still collect debris, and we will tell you what to clear and how often.
