Roof Repairs:

  • A tile roof may only be repaired if the same style and size of tile is available. If wind causes damage to 15% of a slope a minimum of that entire slope must be replaced, including the ridge and rake. All tiles must be nailed or screwed to a batten using 2 fasteners.
  • Wood Shake and Wood Shingle roofs must be replaced if more than 10% of the entire roof or more than 25% of any one slope need to be repaired. These percentages include shingles that must be replaced due to damage to adjacent shingles, valley metal or other roofing elements or materials.
  • Repairs to roofs that meet the current Building Code and have approved materials are allowed up to an aggregate amount of 25% of the roof. This percentage include shingles that must be replaced due to damage to adjacent shingles, valley metal or other roofing elements or materials. Repairs over 25% of the total roof require a total reroof.
  • Woodruff and other similar composite shingles are no longer approved roof covering material. These roofs may not be repaired but must be replaced when damage occurs.
