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 Kamloops

Built for fire season

The Thompson is dry country with long fire seasons, and plenty of homes back onto grassland or forest. 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.

Hot summers, hard sun

Kamloops summers are among the hottest in BC. Interlock's Alunar® colours are rated by the Cool Roof Rating Council, and the manufacturer's coating warranty spells out the fade and chalk limits.

Cold snaps and snow

Winters bring cold snaps and snow on the higher ground. A metal roof sheds snow, so snow guards over entries, decks and driveways go in at the estimate, and the light panels leave the framing's capacity for the snow itself.

Locked on four sides

Interlock panels lock to each other on all four sides with the fasteners concealed. Wind resistance is warranted to 193 km/h (120 mph) installed to manufacturer specification.

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 Kamloops?

Interlock Metal Roofing (BC) Ltd. installs Interlock® aluminum shingles across Kamloops and the Thompson, with 26 roofs completed. The panels are made in Delta, BC. Call (778) 745-2860 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.
