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.
Months of rain, moss, character homes, strata councils and more homes going solar every year.
Nothing in an aluminum panel for moss to root in or water to rot. Cedar softens and asphalt granules trap the debris moss grows in.
The look of cedar shake or slate on an older house, at a fraction of the weight, and paperwork strata councils can approve.
Put the panels up once. The roof under them outlives the array.
From White Rock to West Vancouver: aluminum cannot rust in salt air.

Mountain snow, wet storms off Howe Sound, and homes that back onto forest.
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.
Class A Fire Rated Available, as a complete assembly, for homes in the wildland-urban interface.
Panels locked on four sides; wind warranted to 193 km/h installed to manufacturer specification.

See this roof 1 photo · Deep Charcoal SlateSurrey roofing profiles we install: cedar shingle, shake, slate, 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 the Interlock® aluminum roofing system on homes south of the Fraser: Surrey, Delta, Tsawwassen, Ladner, Langley, Aldergrove and White Rock. The panels are made in Canada at the Interlock plant in Delta, a few minutes from most of the homes on this page.
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 metal, for Surrey roofing
Local
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.
Rain & moss
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.
Wind
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.
Acreages
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.
Recycled
And the last tear-off your house is likely to need.
The metallurgy, coatings and test reports are the manufacturer's to explain: interlockroofing.com ↗
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.

9969 River Way, Delta, BC, the same address as the Interlock plant that makes the panels. Estimates in Surrey & South of the Fraser are by appointment; call (604) 210-3850.
A Surrey roofing contractor, based in Delta, that installs one roofing system: the Interlock® aluminum roof, made in Canada in Delta. We replace asphalt, cedar and tile roofs on Surrey, Delta, Langley and White Rock homes with it.
