Spokane winters bring repeated freeze-thaw cycles that drive ice dams along eaves, especially on 1950s–1970s homes in South Hill and Browne's Addition where original ventilation is often undersized. A proper replacement starts with complete tear-off to inspect decking for rot caused by years of trapped moisture, then adds ice-and-water shield along the lower six feet and all valleys before new underlayment goes down. Homeowners in Spokane County also face wind-driven rain from the Palouse that tests every flashing detail around chimneys and skylights.
Asphalt shingles remain the most common choice here because they handle thermal expansion without cracking, but metal panels are gaining ground on steeper pitches in Liberty Lake where snow slides off cleanly. We match existing ridge vents and eave baffles to keep attic temperatures stable, which prevents the condensation problems common in single-story ranches. Every job includes new drip edge and step flashing tucked under existing siding so water cannot migrate behind the walls during spring runoff.
Building codes in Spokane require 130 mph wind rating on new roofing and proper nailing patterns for seismic zones. Skipping the tear-off to save cost often leaves old layers that trap heat and shorten the life of the new roof by several winters. We schedule tear-offs only when dry forecasts allow the deck to stay exposed overnight, protecting the interior from sudden mountain weather shifts.
Technician insight
In Spokane, the thing that catches most people out with roof replacement is the hidden rot under old layers on 1960s–70s homes in the South Hill where poor original ventilation let ice dams leak for years; once we tear off we often find the deck needs more plywood than expected.
South Hill Ice Dam Repair and Replacement
Homeowner called after repeated ceiling stains from winter ice dams. Tear-off revealed rotted decking along the north eaves and blocked soffit vents. We replaced damaged plywood, added full ice-and-water shield, upgraded ridge venting, and installed new architectural shingles matched to the neighborhood. No further leaks reported through the next two winters.
