Spokane commercial buildings often feature low-slope or moderate-pitch roofs on masonry and steel-frame structures from the early 1900s through the 1970s. Metal panels handle the region's repeated freeze-thaw cycles better than membrane systems when seams and fasteners are detailed correctly. We specify 24- or 26-gauge Galvalume or painted steel standing-seam systems with hidden clips that allow thermal movement without tearing through screw holes.
Wind-driven snow and ice dams along the roof edges are common on exposed sites near the Spokane River or in the South Hill commercial districts. We add extra clip spacing, ice-dam clips, and positive drainage at valleys and gutters to meet current Spokane building department requirements for commercial re-roof permits. Edge cases include tying new metal into existing clay-tile parapets or matching historic downtown facades while still achieving a 40-year weathertight warranty.
Before any panel is installed we verify deck attachment, insulation R-value, and vapor retarder condition because many Spokane warehouses still have original wood plank decks over unvented attics. Skipping these steps leads to condensation staining inside the building the first winter after the new roof goes on.
Technician insight
In Spokane the thing that catches most people out with commercial metal roofing is underestimating how much the wood plank decks on pre-1960 buildings move when the first big snow load hits. If the original deck boards aren't re-secured before new panels go down, the screws back out within two winters.
Warehouse Roof on East Sprague
A 1970s warehouse near East Sprague had recurring leaks at the ridge after heavy snow. We found the original screws had backed out where the deck flexed. We added purlins, switched to sliding clips, and installed new 24-gauge standing seam panels. The building stayed dry through the next two winters with no further callbacks.
