A reproof permit is required for re-roofing 500 square feet or
more. Clay tile or concrete tile that weighs more than 6 pounds
per foot requires structural calculations. No more than two overlays
of asphalt shingles are allowed over the existing asphalt or wood
shingle roof. Not more than one overlay of wood shakes or wood shingles
shall be applied over the existing asphalt or wood shingle roof.
Reroof Permit Requirements
All roofing material must be fire retardant and all wood shingles
or shakes must be pressure treated (Class C minimum rating). Permit
fees are based upon square footage of reroof and material used.
Reroof permits that do not require calculations are issued over
the counter unless. If calculations are required, the plan check
can take up to 7 days.
