Abrasion is wear, and wear is excluded everywhere
Blowing sand scours paint, pits glass, degrades roof surfaces and wears seals over years. No homeowners policy covers deterioration however it was caused, so none of that is a claim. It is a maintenance budget rather than an insurance question, and knowing that saves a wasted claim.
What a storm does suddenly may be covered
A single severe event that lifts roofing, breaks glass or drives debris into a structure is sudden damage rather than wear. The distinction a carrier draws is between gradual degradation and an identifiable event, and prompt reporting after a storm is what keeps a claim on the right side of it.
Worn surfaces fail faster in the next event
Roofing degraded by years of abrasion lifts in winds that would not have moved it when new. That is where the two halves meet: the wear is yours, and the failure it enables may be a claim. Replacing surfaces on schedule is what keeps the policy relevant.
