Metal roofing in Duncan & Cowichan
Old roofs in the mildest weather in the country.
The Cowichan Valley has some of the gentlest weather anywhere in Canada and a housing stock with a lot of years on it.
Those two facts point at the same thing.

Mild doesn’t mean easy on a roof
Mild here means wet in the way that actually degrades a roof — long grey stretches rather than dramatic storms, shade that never fully dries, and moss establishing on any surface with enough texture to grip.
That’s the classic case for a smooth continuous plane. A standing seam roof gives moss much less to hold than shingle does, and sheds sustained rain rather than holding it at every lap. The damage moss does is not that it eats the roofing — it traps moisture and debris against the surface and keeps the assembly wet.
The housing stock is the other half
A large share of the valley’s roofs are on buildings that went up decades ago, which means two things.
Tear-off is revealing
Decking, ventilation and forty years of previous repairs all surface once the covering is off. Frequently that’s the hour that changes the scope, and it’s worth carrying a contingency for what turns up rather than being surprised by it.
Ventilation is often the real problem
Older assemblies were built to different expectations, and sealing a new roof over an under-vented cavity is a way of preserving a problem. A reroof is the moment to deal with it, and it’s also the practical window for insulation if the assembly is otherwise inaccessible.
South of the shop, an easy run
The Cowichan Valley is a straightforward delivery from Nanaimo: panels formed to your measurements and brought down the highway, with no ferry and no long rural approach in most of the valley.
Where it does get rural — up toward Lake Cowichan or off the main roads — the driveway and the panel length are worth raising early.
Buying material instead
Plenty of Cowichan Valley roofers and builders buy panels from us and do their own installing. If that’s you, send a takeoff or plans — custom lengths and matching trim, formed to your job, no mainland lead time. Any address you bring us is protected for twelve months.
Permits in the Cowichan Valley
Which office depends on where the building is. The City of Duncan issues its own building permits, the Municipality of North Cowichan issues its own, and the Cowichan Valley Regional District covers the electoral areas.
Worth naming clearly, because it catches people out: on Vancouver Island “CVRD” means both the Cowichan Valley Regional District and the Comox Valley Regional District. They are different bodies. We confirm the right one for your address before starting.

Duncan & Cowichan questions.
Yes, across the Cowichan Valley.
Mild wet weather and shade are ideal for it, and it holds moisture against the roof. A smooth continuous metal plane gives it far less to grip than shingle does.
If the assembly is hard to reach otherwise, it’s the practical window — and insulation is the part where rebate money exists in BC. The roof itself isn’t rebated.
