Home insurance covers garage door damage only if the cause is a sudden, accidental covered peril, such as vehicle impact, windstorm, hail, fire or vandalism. For attached garage doors, the applicable coverage is dwelling coverage (Coverage A). For detached garage doors, coverage falls under other structures (Coverage B). The two most common reasons claims are denied are mechanical failure and maintenance exclusions. Neither qualifies as a covered peril under a standard HO-3 policy.
The attached versus detached distinction affects more than claim approval. It directly determines your coverage limit. A detached garage door defaults to Coverage B, which is 10% of your dwelling limit. On a $250,000 dwelling policy, that ceiling is $25,000. If your detached garage has substantial rebuild value, that limit matters.
