Roof Replacement in Courtenay
Full tear-off and re-roofing in shingle, metal, or cedar — vented and flashed for the Comox Valley coast.
A roof replacement in Courtenay typically runs $8,000 to $20,000 for asphalt shingles and $18,000 to $45,000 or more for metal, set by roof size, pitch, and the number of old layers to strip. Courtenay Roofers tears off, re-decks where needed, re-flashes, and re-roofs across Courtenay, Comox, and Cumberland, with insured, manufacturer-certified crews and free roof quotes.
Most Courtenay re-roofs 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
A proper replacement starts with a full tear-off down to the sheathing, so any soft or rotted deck — common under a moss-worn coastal roof — gets found and replaced before the new roof goes on. Roofing over old shingles hides those problems and shortens the new roof's life.
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. The right pick depends on the home, the budget, and how long the owner plans to stay.
Flashing, venting, and the details that last
Most roofs fail at the details, not the field — valleys, chimney and skylight flashing, and attic ventilation. Getting these right is what separates a roof that reaches its rated life from one that leaks in five years, and it's where a coastal re-roof earns its keep.
How a Courtenay re-roof works
- 1
On-site assessment — A roofer measures the roof, checks pitch, layers, and problem areas, and confirms whether the project needs a permit.
- 2
Itemized quote — A written quote covers tear-off, deck repair allowance, underlayment, flashing, material, and cleanup.
- 3
Tear-off & deck check — The old roof is stripped to the sheathing and any rotted deck is replaced before new material goes down.
- 4
Re-roof & cleanup — Underlayment, flashing, roofing, and venting go on to manufacturer spec, then the site is magnet-swept and the debris hauled away.
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 coastal re-roofs lean on quality underlayment, generous flashing, and good attic ventilation — and why metal is a growing choice for homeowners who 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
- The crew 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?
Most residential re-roofs take one to three days of on-site work once materials are on hand, depending on roof size, pitch, and 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. A full tear-off is the standard for 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; a permit is required if the material changes, the structure is altered, or the slope changes. The City of Courtenay confirms per project.
