Spokane roofs face repeated wind events from the Columbia Basin, heavy spring hail, and winter snow loads that exceed 20 pounds per square foot on many older homes. Asphalt shingles on South Hill and Perry District houses built before 1980 often show granule loss and lifted tabs that are not visible from the ground. A proper assessment checks underlayment integrity, flashing around chimneys, and nail pops caused by thermal cycling between freezing nights and daytime thaw.
We start at the ridge and work downward, documenting wind-driven rain entry points at valleys and eaves where Spokane's frequent freeze-thaw cycles accelerate rot in decking. Hail damage is measured by impact crater diameter on both slopes and ridge caps; even small dents can crack the underlying felt when temperatures drop below 20 degrees. Access challenges on steep lots in Browne's Addition or tree-covered properties near Manito Park require extension ladders and drone photos to avoid missing sections.
Documentation includes photos, measurements, and notes on code requirements for Spokane County permitting when more than 25 percent of the roof is affected. Homeowners receive a written report that insurance adjusters accept without follow-up visits. We schedule assessments Monday through Friday 8am–6pm and Saturday 9am–2pm to match typical daylight availability after storms.
Technician insight
In Spokane, the thing that catches most people out with Storm damage assessment is hidden rot under lifted shingles on pre-1970 homes in the Perry District and South Hill where wind funnels between mature trees and snow sits for weeks.
South Hill Wind Damage
A homeowner noticed missing shingles after a March windstorm. We found lifted tabs and torn underlayment along the north slope plus water stains in the attic near a valley. Repairs were isolated to the affected section before rot spread into decking.
