Spokane homes built before 1960 on the South Hill and in Browne's Addition often carry multiple layers of asphalt that exceed current weight limits once snow piles up. Full replacement starts with complete tear-off to the decking so new underlayment can be applied without trapping moisture that leads to rot in the cold, wet springs common here. We match pitch and eave details to the original construction while adding ice-and-water shield along valleys and eaves to handle the freeze-thaw cycles that split older shingles.
Metal standing-seam systems perform well on North Spokane and Spokane Valley properties where wind gusts along the river corridors reach higher speeds. These panels resist uplift better than traditional shingles and shed snow faster, reducing the chance of ice dams that form on poorly ventilated attics. Proper ridge venting must be calculated for each roof plane because many 1920s–1940s homes have limited soffit intake, which we correct during the job to meet Spokane County ventilation guidelines.
Low-slope sections on garages and additions require modified-bitumen or TPO membranes rather than shingles. Transitions between steep and flat areas need custom step flashing and counter-flashing to prevent leaks that show up after the first heavy November rain. We inspect decking for water damage from past ice dams before any new material goes down, because hidden rot in sheathing is the most common reason a replacement job stretches beyond the original timeline.
Technician insight
In Spokane the thing that catches most people out with full roof replacement is the hidden deck damage from repeated ice dams on South Hill homes that lack proper ridge venting; once we open the roof we often find the sheathing needs replacement before any new material can go down.
South Hill Ice-Dam Repair Turned Full Replacement
A 1938 home near Manito Park showed recurring ceiling stains after heavy snow. Tear-off revealed widespread rot along the eaves from missing ice-and-water shield and blocked soffits. We replaced damaged decking, added full ice-and-water coverage, installed a standing seam metal roof with upgraded ridge venting, and the leaks stopped through the next winter.
