Is My Roof Damage From the Storm, or Was It Already Wearing Out?
How to distinguish sudden storm-related roof damage from gradual pre-existing wear — the distinction that determines whether Washington homeowners insurance covers it.
Storm damage typically looks localized and sudden — torn or displaced shingles, debris impact, damage concentrated on the wind-facing side. Pre-existing wear looks uniform across the whole roof — curling, granule loss, and aging spread evenly regardless of wind direction. The distinction matters because insurance covers one and not the other.

This is the single most important distinction in a roof insurance claim, and it’s not always obvious from the ground.
What storm damage typically looks like
- Localized to one area or one wind-facing slope, rather than spread evenly across the whole roof
- Torn, creased, or completely missing shingles, rather than curling or cracking
- Debris impact marks — dents or punctures from branches or wind-blown objects
- Displaced ridge caps or flashing, lifted rather than simply worn
- A clear before/after — you can often point to a specific date when it appeared
What pre-existing wear typically looks like
- Uniform across the entire roof, regardless of which direction faced the storm
- Curling, cupping, or granule loss spread evenly rather than concentrated
- Consistent with the roof’s age — closer to or past its expected service life (realistically around 17 years for asphalt shingle in this climate, well short of the 25-30 year manufacturer rating)
- No specific date it “started” — it’s been gradually developing over years
Why the distinction is genuinely hard sometimes
Real roofs often show both at once: an aging roof that then takes storm damage on top of its existing wear. In that case, the honest answer isn’t “one or the other” — it’s documenting both separately, since a wind event can still be a covered loss even on a roof that wasn’t in perfect condition beforehand, though the payout may account for pre-existing condition.
How we make this call
At a storm-damage inspection, we look for the specific storm-damage indicators above, document the roof’s overall age-related condition separately, and give you an honest read on both — not just whichever answer makes a bigger job for us. This same documentation is useful whether or not you end up filing an insurance claim.
What to do next
If you’re not sure which situation you’re looking at, a free inspection with photo documentation settles it. See our insurance coverage guide for what happens once you know which category applies.
The bottom line
The direction, pattern, and uniformity of the damage tell the real story. Call for a free assessment and we’ll document what we actually find, honestly.
The bottom line
