Cedar roof maintenance, repair and replacement options
Cedar can be maintained or repaired when shakes remain thick, sound and well ventilated. Widespread splitting, softness, erosion or repeated face-nailed patches usually points toward replacement or conversion. North slopes and shaded valleys may deteriorate faster.
Inspect condition by roof area
North slopes and shaded valleys may deteriorate faster. Judge thickness, splits, cupping, fasteners and underlayment, not colour alone.
Use gentle maintenance
Remove debris and biological growth with material-compatible methods. Aggressive pressure can damage the wood fibres.
Compare replacement paths
New cedar preserves the material character; asphalt or metal conversion changes weight, detailing, appearance and maintenance. Deck and ventilation must be reviewed.
Details worth checking
