Timber shingles/shakes – warped shingles

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. 

Cause

Roof at end of serviceable life
