Spokane roofs take repeated hits from heavy winter snow followed by rapid spring thaws and rain. Many homes in Logan, Browne's Addition, and the South Hill were built between 1910 and 1950 with original cedar or early asphalt layers that now show seam separation and flashing fatigue. A small leak around a chimney or valley often travels along rafters before showing up in an upstairs ceiling, which is why we always start with attic inspection rather than guessing from the ground.
We carry matching shingles for the common three-tab and architectural styles found on Spokane's older stock and keep ice-and-water shield on the truck for quick valley and eave work. When leaks trace to improper step flashing on brick chimneys, we replace the counter-flashing and re-seal with high-temp caulk rated for our temperature swings. Homeowners sometimes try sealant from a can on a Sunday; those patches rarely survive the next freeze cycle and usually require full section replacement once we arrive.
Code requires proper ventilation and drip edge on re-roof projects in Spokane County, and we check both during every leak call. Blocked soffit vents combined with ridge vent issues create ice dams that push water under shingles along the north-facing eaves common on Spokane's east-west streets. Addressing the ventilation problem at the same time prevents the same leak from returning the following winter.
Technician insight
In Spokane the thing that catches most people out with roof leak repair is how quickly a small valley leak turns into widespread attic saturation once the freeze-thaw cycle starts in March. Homes on the South Hill and in Logan often have original cedar or thin asphalt that hides damage until water reaches the ceiling. We always check ventilation at the same time because blocked soffits are the hidden reason the same leak returns every spring.
South Hill Valley Leak
Water stains appeared on a second-floor ceiling after a March rain-on-snow event. We traced the path to an open valley on a 1940s home where the original metal had corroded. New step flashing, ice-and-water shield, and matching shingles were installed along the valley and the attic was dried out. No further staining occurred through the next winter.
Roof Leak Repair Services We Offer
✓Attic Leak Tracing
We locate the exact entry point from inside the attic using moisture meters and insulation inspection so exterior repairs target the real source instead of guessing.
✓Valley and Flashing Repair
Open valleys and deteriorated step flashing are common leak points on Spokane homes; we replace metal and re-seal with ice-and-water shield rated for freeze-thaw cycles.
✓Chimney and Skylight Sealing
Cracked counter-flashing and failed skylight boots let water run down masonry or framing; we install new lead or step flashing and high-temperature sealant.
✓Ice Dam Leak Mitigation
North-facing eaves on Spokane homes often develop ice dams after heavy snow; we remove dams safely and add heat cable or improved ventilation to stop recurrence.
✓Shingle Section Replacement
When wind or hail lifts individual shingles on South Hill and West Central roofs, we match existing material and replace only the damaged courses without a full roof replacement.
