What makes an aluminum shingle different

An aluminum shingle is a stamped aluminum panel with a baked finish. Unlike a steel shingle, there is no steel core under the finish, so there is nothing to rust if the finish is scratched or cut. The exposed aluminum forms an oxide film that blocks further oxidation (ASM International).

Interlock® aluminum shingles lock to each other on all four sides. The fasteners sit under the course above, out of the weather, so the roof has no exposed screw heads and no rubber washers to age.

Aluminum shingles in Surrey

Made down the road, in Delta

Our office and the Interlock plant share one address: 9969 River Way in Delta. The roof on your house is made south of the Fraser and installed south of the Fraser by a Canadian owned and operated BC company.

Months of wet, every winter

Cedar holds water and softens; asphalt granules trap the debris moss grows in. Aluminum absorbs nothing and cannot rot. Gutters and valleys still collect leaves, and we'll tell you what to clear and how often.

Open ground and storms off the water

Tsawwassen, Ladner, White Rock and the farmland in between take storms with little in the way. Interlock panels lock on all four sides with the fasteners concealed, and wind resistance is warranted to 193 km/h (120 mph) installed to manufacturer specification.

House, garage and shop to match

On Langley and Aldergrove acreages the same profiles go on the house, a detached garage or a shop, so everything on the property can match and carry the same system, as long as each roof has at least a 3/12 slope.

Questions, answered

What are aluminum shingles?

Aluminum shingles are roofing panels stamped from aluminum sheet and finished with a baked coating, made to look like slate, cedar shingle, shake or tile. Interlock® aluminum shingles interlock on all four sides with concealed fasteners.

Do aluminum shingles rust?

No. Aluminum forms a thin oxide film that blocks further oxidation, and there is no steel inside an aluminum shingle to rust, which is why they suit homes near salt water.

Are aluminum shingles better than steel shingles?

Aluminum doesn't rust and is about one-third the density of steel. Steel shingles usually cost less up front and depend on their zinc or aluminum-zinc coating to keep from rusting. Aluminum can dent under large hail.

How thick are Interlock aluminum shingles?

0.019 in (0.483 mm) nominal base thickness, aluminum alloy per ASTM B209, according to the manufacturer's specification.

Where can I get aluminum shingles installed in Surrey?

Interlock Metal Roofing (BC) Ltd. installs Interlock® aluminum shingles across Surrey and South of the Fraser, with 310 roofs completed. The panels are made in Delta, BC. Call (604) 210-3850 or book a consultation on Zoom.

Can aluminum shingles be installed over asphalt?

A single layer of asphalt can be roofed over only if our inspection finds it suitable. Cedar shakes, concrete tile and natural slate always come off first.

Do aluminum shingles help with moss?

Aluminum absorbs no water and cannot rot, so moss has nothing to root into the way it does in cedar or between asphalt granules. Needles and leaves still collect in valleys and gutters on a shaded roof, so keep those clear.
