Roof Replacement in Courtenay
We tear off and re-roof in shingle, metal, or cedar, vented and flashed for the Comox Valley coast.
Courtenay Roofers tears off, re-decks where needed, re-flashes, and re-roofs homes across Courtenay, Comox, and Cumberland. Replacing your roof typically runs $8,000 to $20,000 in asphalt shingles and $18,000 to $45,000 or more in metal, set by roof size, pitch, and how many old layers we strip. Our crews are insured and manufacturer-certified, and the roof quote is free.
Most Courtenay re-roofs we quote land between $8,000 for a straightforward asphalt shingle roof and $45,000 or more for metal on a large or steep home.
Tear-off, deck, and what's underneath
We tear off the old roof down to the sheathing, so we can find and replace any soft or rotted deck before the new roof goes on — common under a moss-worn coastal roof. Skip that step and roof over the old shingles, and you just hide the damage and cut the new roof's life short.
Choosing shingle, metal, or cedar
Architectural asphalt shingles are the affordable standard at $8,000 to $20,000 for a typical Courtenay home and last 15 to 30 years. Metal costs more, $18,000 to $45,000 or more, but lasts 40 to 70 and sheds the coast's rain and moss far better. Cedar suits heritage homes but needs upkeep. Which one's right for you comes down to the home, the budget, and how long you plan to stay.
Flashing, venting, and the details that last
Most roof leaks trace back to the details: valleys, chimney and skylight flashing, and attic ventilation. Get those right and your roof reaches its rated life. Get them wrong and it leaks within five years. We spend our time there, because that's where a coastal re-roof earns its keep.

Local conditions
The Comox Valley takes some of the heaviest rain on Vancouver Island, and shaded north-facing roofs grow moss that shortens shingle life. That's why we lean on quality underlayment, generous flashing, and good attic ventilation on every coastal re-roof. It's also why more homeowners are choosing metal if they don't want to re-roof again in fifteen years.
In practice
- Situation
- A Courtenay homeowner had a 22-year-old shingle roof shedding granules and growing moss on the north slope.
- Complication
- Tear-off revealed soft, water-stained sheathing under the worst moss, so a simple shingle-over would have trapped the rot.
- Resolution
- We replaced the damaged deck, upgraded the valley flashing and attic venting, and installed architectural shingles rated for the coastal climate.
People also ask
How long does a roof replacement take?
We are usually on site one to three days for a residential re-roof once the materials are on hand, depending on your roof's size and pitch and the weather.
Can you roof over old shingles?
It's sometimes allowed, but on a coastal roof it's a false economy: it hides rotted deck and traps moisture. We do a full tear-off, because that's what gives you a roof that lasts.
Do I need a permit to replace my roof?
A like-for-like re-roof usually needs no permit in BC. You need one if the material changes, the structure is altered, or the slope changes. We confirm it with the City of Courtenay for your project.
