Roof Repairs:

• 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.
