Tree limbs falling onto roofs in Spokane often occur during winter wind events or heavy snow loading on mature trees common in South Hill and Browne's Addition. Older homes built before 1950 frequently have asphalt shingles that crack or dislodge on impact, allowing water to reach the underlayment and decking. A single limb strike can create localized depressions that hold snowmelt, accelerating rot along rafters if not addressed before spring runoff.
Edge cases include limbs that glance off the roof edge and tear flashing around chimneys or skylights, especially on homes with steep pitches found in the lower South Hill. Hidden damage often appears as displaced felt paper or cracked ridge caps that only show during heavy rain. Crews check for compromised sheathing by probing from the attic side rather than relying solely on exterior inspection.
Spokane County permitting rules require documentation of structural repairs when decking replacement exceeds 25 percent of the roof plane. Homeowners should verify that any limb removal crew has cleared the roof of debris before temporary coverings are installed, as leftover bark and needles trap moisture against the shingles during the next freeze-thaw cycle.
Technician insight
In Spokane the thing that catches most people out with tree limb removal impact is the way heavy snow load on South Hill roofs hides cracked decking until the first warm spell sends meltwater straight into the attic.
South Hill limb strike on 1940s home
A large maple limb dropped during a February wind event and punched through three courses of shingles. Inspection revealed split decking and a bent rafter hidden under snow. We removed the damaged materials, sistered the rafter, replaced the deck section, and matched the existing shingles before resealing the ridge.
