Cedar shake to asphalt: what it costs and what's involved
Short answer
Most BC homeowners replace cedar shakes with asphalt shingles because asphalt costs far less — about $4–$9 per square foot versus $14–$30 for new cedar — and needs much less upkeep. Because cedar is often installed over spaced boards, a conversion usually adds a layer of plywood before the new asphalt roof goes on.
| Cedar shake | Asphalt shingle | |
|---|---|---|
| Typical cost per sq ft (BC) | $14 – $30 | $4 – $9 |
| Lifespan | 25–50 years | 15–30 years |
| Maintenance | Regular — moss, splitting, treatment | Low |
| Fire resistance | Lower unless treated | Higher |

Common questions
Why does a cedar-to-asphalt job need new plywood?
Cedar shakes are often installed over boards with gaps between them. Asphalt shingles need a solid deck, so plywood goes on first.
How long does a cedar-to-asphalt conversion take?
Usually three to five working days for a typical house, depending on size and weather.
Can I switch from cedar to metal instead?
Yes. Metal costs more than asphalt but lasts much longer. We can quote both so you can compare.
