When a roof is repaired the surrounding shingles and sometimes other protective components need to be removed. There can be a “domino effect” of damage with an extensive repair. There is no formula for how much damage is required. We would prefer to see you get a full roof replacement when it is in your best interest. Therefore if we feel that the damage is too extensive to repair, we will fight for you to try to get the insurance to agree to get your whole roof replaced.
