Why Choose Red Maple for Cedar Shake to Asphalt Conversion?
Many homes in Coquitlam, Port Moody, West Vancouver and Vancouver were built with cedar shake roofs that are now 25 years old or more. In our wet climate, aging cedar splits, cups, grows moss and starts to rot, and patching it gets harder every year. Converting to architectural asphalt removes most of that upkeep.
A cedar conversion is more involved than a regular reroof. Cedar is installed over spaced boards (skip sheathing), and asphalt shingles need a solid deck, so we install new plywood or OSB sheathing over the whole roof before anything else goes on. Some homeowners also find it easier to arrange insurance after replacing an old cedar roof; check with your insurer for your policy.
How We Work
Inspection & Quote
We assess the cedar, the skip sheathing and the attic, and quote the conversion in writing including sheathing and ventilation.
Strip to the Framing
All shakes, felt interlay and ridge caps are removed and disposed of.
New Solid Deck
Full sheets of plywood or OSB sheathing are fastened over the existing skip boards to create a solid, code-compliant deck.
Ventilation, Underlayment & Shingles
Intake and ridge ventilation corrected, ice-and-water shield and synthetic underlayment installed, then architectural shingles including shake-look options.

Cedar Roof Replacement
Most cedar roofs we replace are converted to architectural asphalt. If you want to keep a wood look, ask about shake-style asphalt lines, which give a similar textured appearance with far less upkeep.
Cedar Shake Conversion Cost
A conversion usually costs more than a standard asphalt reroof of the same size because of the new sheathing, extra disposal and ventilation work. We itemize those costs on the quote so you can see exactly what you are paying for.
Replacing Cedar Shingles with Asphalt
Cedar shingles (thinner, sawn) and cedar shakes (thicker, split) are both installed over skip sheathing, so the process is the same: strip, new solid deck, ventilation, underlayment and asphalt.
Our honest advice
If your cedar roof still has good years left, we will tell you. Conversion makes sense when the cedar is failing, not just because it is old.
