Timber shingles/shakes – warped shingles
Listed under: timber and wood-based, timber, Roof, cladding, roof cladding, timber shingles and shakes
Cause
Timber movement due to swelling and shrinkage
Repair
- replace warped shingles: carefully lift adjacent shingles and remove damaged shingle, insert replacement shingle and replace adjacent shingles.
- if more than 10% of the shingles need replacing, the whole roof should be replaced. If the old shingle roof has met minimum Building Code durability provisions (it has lasted at least 15 years) a building consent is not required; if not, a consent must be obtained before reroofing. Reroofing with a different cladding type will require a consent.

Roof at end of serviceable life
