Roofing & Materials
Weathering vs Damage
Weathering is the gradual breakdown of a roof from sun, rain and temperature swings, while damage is a distinct event such as hail or wind. The two look alike, so a claim leans on the date of loss, matching damage on other slopes and test squares, because carriers argue weathering where the evidence is thin.

More roofing & materials terms
- Ventilation
The intake-and-exhaust system that keeps the attic cool and dry, required by code in most areas.
- Wear Pattern
A wear pattern is the gradual deterioration that age, sun and foot traffic leave across a roof, unlike the random or directional marks a storm leaves. Adjusters use it to separate maintenance from storm damage, so photograph whole slopes, not just the worst spots, or your claim can be read as normal aging.
- Wind damage
Roofing damage from wind uplift, lifted shingles, exposed nail heads, and torn flashing.
- Wind Speed Rating
A wind speed rating is the maximum wind a product is tested to withstand, shown on shingle, panel and fastener literature as a rated speed. Carriers and code officials may require a rated product or a specific fastening pattern in high-wind areas, so keep the product literature and fastening detail in the claim file.
- Wind Uplift
Wind uplift is the suction wind puts on a roof as it passes over, pulling at edges, corners and field shingles instead of pushing down. That is why fastening at the perimeter, the corners and the ridge matters more than field fastening - corners see the highest uplift - and why edge-only damage can raise questions about whether the roof was installed to code.
