## Answer

Insurance carriers commonly authorize a full roof replacement instead of a repair when covered storm damage affects more than roughly 25–33% of a slope, when color-matching aged shingles is impossible, when local ordinance requires a matching roof surface, or when the shingle line has been discontinued — the exact threshold depends on the policy and state.

## The rules aren't uniform

Per III policyholder guidance, state matching statutes vary widely — some states (IA, CT, KY) require insurers to match undamaged sections; most states do not. Where matching is required, insurers often pay for a full slope or full roof rather than argue over color.

The most common path to a full-roof approval is a Class 4 (UL 2218) hail event verified by NOAA SPC data plus a HAAG-standard inspection showing 8+ hits per 100 sq ft on multiple slopes.
