Spokane winters bring repeated freeze-thaw cycles that push water under shingles and through flashing on homes built before 1970 in neighborhoods like South Hill and Browne's Addition. These older roofs often use organic felt underlayment that has dried out, allowing small penetrations from ice dams or wind-driven rain to reach the deck. A proper repair starts with tracing the actual water path rather than patching the visible stain, because leaks frequently travel along rafters before showing up inside.
We work with both asphalt composition shingles common on Spokane tract homes and the occasional cedar shake roofs found in older sections of the city. When replacing damaged sections we match existing weight and color while adding ice-and-water shield at eaves and valleys to handle the heavy spring runoff that drains toward the Spokane River. Edge cases include leaks around masonry chimneys on pre-war houses where the original counter-flashing has corroded and around skylights installed without proper step flashing during 1980s remodels.
Attic ventilation in Spokane County homes is often inadequate for the snow load, leading to condensation that mimics a leak. Before any repair we check ridge and soffit venting plus insulation levels to prevent future moisture issues. All work is performed during posted hours and we leave the site clean enough for a follow-up inspection the next day.
Technician insight
In Spokane the thing that catches most people out with Roof Leak Repair is hidden rot along the north-facing eaves on South Hill homes where snow sits longest and ice dams push water under the original felt underlayment long before any interior stain appears.
South Hill Ice Dam Leak
Homeowner noticed water stains in an upstairs bedroom after a March thaw. Inspection found ice dam damage at the north eaves with failed underlayment allowing water to reach the deck. We removed the dam, replaced the compromised section with new ice-and-water shield and matching shingles, then checked attic ventilation. No further leaks occurred during the remaining spring runoff.
