Weathering vs. Damage

Normal Aging vs. Sudden Loss

Weathering is the gradual, expected deterioration of roofing materials from years of sun exposure, rain, wind, and temperature cycling, while damage is a sudden impairment of function caused by a specific covered event like a hailstorm, windstorm, or fallen tree. Insurance covers damage from covered events. Insurance does not cover weathering, which is considered normal wear and maintenance. The distinction between the two is one of the most debated topics in property insurance claims.

Learning to distinguish weathering from damage, and to document the difference, is a critical skill.

How to Identify Weathering

Weathering presents as uniform deterioration across the entire roof. Granule loss from weathering is even across all slopes, regardless of orientation. Curling, cracking, and brittleness from aging affect all shingles of the same age equally. Discoloration from algae or UV exposure is gradual and widespread. There is no directional pattern, no random impact points, and no sudden onset tied to a weather event. If every shingle on the roof looks the same regardless of slope orientation, you are likely looking at weathering.

How to Identify Storm Damage

Storm damage presents differently. Hail damage creates random impact points with concentrated damage at the strike and intact material between strikes. Wind damage follows the wind direction, typically worse on windward slopes and at edges and corners. Debris damage is localized to the impact area. Storm damage appears suddenly after an event and is inconsistent with the prior condition of the roof. Document the contrast between storm-affected areas and protected areas to show that the observed damage is event-specific, not age-related. A slope sheltered from the storm that shows no damage while the exposed slopes are damaged is strong evidence of storm causation.
