Spokane winters bring repeated freeze-thaw cycles and heavy snow that adds significant load to roof structures. Homes on the South Hill and in Browne's Addition often carry two or three layers of shingles from earlier decades, increasing the risk of deck damage once removal begins. Metal or architectural asphalt systems rated for 50 psf snow load perform best here because they shed snow faster than standard three-tab shingles.
Spokane County requires permits for any roof replacement that involves structural deck repair or changes to roof pitch. Older homes near the river or in the lower South Hill can have hidden rot from past ice dams that only appears after tear-off. We always pull back at least one layer completely so the deck can be inspected and any needed plywood replacement or ice-and-water shield upgrades can be completed before new underlayment goes down.
Wind gusts along the Palouse and through the Spokane Valley regularly exceed 50 mph, so ridge vents and flashing details must be secured with ring-shank nails and high-temperature sealant. Flat sections on garages or additions common in Spokane's post-war neighborhoods need tapered insulation and fully adhered membranes rather than mechanically fastened systems that can lift in high wind.
Removal of existing layers, deck inspection, new underlayment, flashing at all penetrations, and final ridge ventilation are completed in one weather window when possible. Homeowners in Spokane County receive a written scope that lists every material grade and the exact number of squares before work starts.
Technician insight
In Spokane, the thing that catches most people out with roof replacement is discovering two or three layers of old shingles plus hidden deck rot on South Hill homes after a heavy winter. The extra weight from snow load means we often have to sister rafters or sister in new decking that homeowners never budgeted for until the tear-off starts.
South Hill Multi-Layer Replacement
Heavy spring snow melt revealed leaking valleys on a 1960s home. Tear-off showed three layers and widespread deck rot along the eaves. We replaced damaged plywood, added ice-and-water shield, and installed architectural shingles rated for local snow load. The roof now sheds snow cleanly and passed Spokane County inspection.
