Spokane winters bring heavy wet snow that bends mature ponderosa pines and Douglas firs over older roofs, especially on the South Hill where homes built before 1960 often have brittle asphalt shingles or remaining cedar shakes. When a limb drops it can tear through underlayment and crack rafters without obvious holes until meltwater finds the path. We assess decking from the attic side first because surface patches alone fail when the sheathing has already compressed under the impact.
Wind events in the Spokane Valley funnel between the basalt ridges and send branches across low-slope sections common on mid-century ranch homes in the Valley and near Liberty Lake. These roofs collect needles and debris that trap moisture against flashings, accelerating rot at the eaves. Tree damage repairs here always include checking the drip edge and step flashing because the original 3-tab shingles were often installed without modern ice-and-water shield along the valleys.
After a full tree removal we replace damaged sections with matching architectural shingles rather than mixing in mismatched bundles, which shows immediately on the uniform roof planes found in Browne's Addition and the West Central neighborhood. We also verify that any new underlayment meets current Spokane County wind-uplift requirements for the exposure category of the lot.
Homeowners sometimes try to seal punctures with roofing tar only to find the underlying felt has already delaminated from the repeated freeze-thaw cycles. A proper repair removes the affected course, inspects the deck, and restores the original nailing pattern so the roof regains its designed load path.
Technician insight
In Spokane the thing that catches most people out with tree damage repair is the compressed sheathing under an impact that looks like just a torn shingle. On the older South Hill homes the decking is often 1x6 skip sheathing that splinters inward, and if you don't catch it the new shingles will telegraph the damage within a year of the next snow load.
Limb strike on a 1950s South Hill ranch
A heavy pine limb came down during a March wind event and punched through the valley on a one-story home near 29th and Grand. We found two cracked rafters and wet insulation from prior meltwater. We sistered the rafters, replaced the damaged decking, installed new ice-and-water shield the full length of the valley, and matched the existing shingles so the repair blended with the rest of the roof.
