The metal

Aluminum doesn't rust

An oxide film protects it; there's no steel inside to corrode.

The warranty

Guardian Lifetime Limited Material Warranty

Material and finish, original purchaser, transferable once.

What an Interlock® aluminum roof is

An Interlock® roof is made of interlocking aluminum panels, each locked to its neighbours on all four sides with the fasteners concealed under the panel above. Nothing is screwed through the weather surface. The panels are stamped to look like slate, cedar shingle, shake or tile, or rolled as standing seam.

The panels are made in Canada by Interlock Roofing at its plant in Delta, BC. Across the Okanagan and Shuswap they are installed by our own company, Interlock Metal Roofing (BC) Ltd., a Canadian owned and operated BC company founded in 1983, from the same Delta address.

Why aluminum, for a roof in the Okanagan

Built for fire season

The Okanagan has lived through serious wildfire seasons, and many homes sit on forested or grassy slopes. 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. We walk the gutters, vents and roof edges with you, because that is where embers get in.

Hot, dry summers

Summer sun is hard on asphalt and cedar. 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.

Real winters too

Vernon, the Shuswap and the benches above the lake get snow. A metal roof sheds it, so snow guards over entries, decks and driveways go in at the estimate, not after the first slide.

Light on the framing

Interlock panels weigh roughly 2 to 3.5 kg per square metre depending on profile, a fraction of concrete tile, which leaves the structure's capacity for snow.

The profiles, and what homeowners in the Okanagan choose

Five aluminum profiles: Slate (the most popular), Cedar Shingle, Shake, Mediterranean Tile and Standing Seam, plus solid copper for bays, porches and accents. Every profile needs a minimum 3/12 slope.

In our job book the most common profiles across the Okanagan and Shuswap are Slate (78), Shake (28), Cedar Shingle (27).

What's covered, in writing

Guardian Lifetime Limited Material Warranty, from the manufacturer: material and finish, for as long as the original purchaser owns the home, transferable once. Workmanship is excluded, and ice damming is a stated exclusion.
30 Year Alunar® Coating Warranty on the finish.
10 Year Limited Labour Warranty from Interlock Metal Roofing (BC) Ltd. on our installation.
Wind resistance warranted to 193 km/h (120 mph) installed to manufacturer specification.
Class A Fire Rated Available, as a complete assembly: two layers of GAF VersaShield® over 12 mm (15/32-inch) plywood, per ASTM E108.

How a roof gets done

From first call to finished roof
Step	What happens
1. Consultation	On Zoom (most BC homeowners choose it) or at your home. We go through profiles and colours, look at photos of roofs like yours, and answer questions.
2. Measure and inspect	We measure the roof and check what's on it now. Cedar, concrete tile and natural slate always come off; a single layer of asphalt can be roofed over only if the inspection finds it suitable.
3. Fixed price in writing	Anything the inspection finds goes into the written quote before you sign, not into a change order later. Strata roofs: we bring the documents the council will ask for.
4. Installation	Our own BC installers, to the manufacturer's specification, with flashing, ventilation and snow guards as planned.
5. Warranties registered	The Guardian material warranty and our labour warranty, with our BC service team after the job.

Questions, answered

Who installs aluminum roofing in the Okanagan?

Interlock Metal Roofing (BC) Ltd. installs the Interlock® aluminum roofing system in the Okanagan from its office at 9969 River Way, Delta, the same address as the plant that makes the panels. The company was founded in 1983 and installs every roof itself. Call (778) 745-2860.

Is aluminum roofing good for the Okanagan and Shuswap?

Aluminum doesn't rust, absorbs no water and cannot rot, so rain, moss and salt air have nothing to work on, and its smooth surface sheds snow. Valleys and gutters still need clearing of needles and leaves, and ice damming is a stated exclusion of the material warranty, so we look at ventilation with you.

Is an aluminum roof better than a steel roof?

They are both metal roofs, but steel depends on its zinc or aluminum-zinc coating to keep from rusting, and aluminum has no steel to rust. Aluminum is also about a third the weight. Steel roofing usually costs less up front. Our steel vs aluminum guide sets out the differences.

How much does an aluminum roof cost in the Okanagan?

It depends on the roof's area, pitch and complexity, what comes off, the profile and options such as the Class A assembly. Our metal roof cost guide shows real price ranges from our own BC contracts, and we give your fixed price in writing after one free visit.

Can an aluminum roof go over my asphalt shingles?

Sometimes: 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.

Can the consultation be done on Zoom?

Yes, and most BC homeowners choose it: we go through the roof, the profiles and the colours with you on screen. Book online or call (778) 745-2860.

How long does an aluminum roof last?

Aluminum has been known to last over 100 years. That is a property of the metal, not a promise; what is in writing is the Guardian Lifetime Limited Material Warranty, the 30 Year Alunar® Coating Warranty and our 10 Year Limited Labour Warranty.
