Commercial roofing crews in Lewiston work on flat and low-slope systems serving port warehouses along the Snake River and retail buildings near the Lewiston Roundhouse. The warm-summer Mediterranean climate produces summer heat that blisters membranes and winter cold that contracts seams along the Clearwater River corridor. Common failures include wind-driven rain leaks at flashings on structures facing Hells Gate State Park and UV degradation on roofs exposed to US-12 traffic.
Commercial Roofing in Lewiston — What We Handle
- ✓Crews must stage materials around active port operations and barge traffic not found in inland Idaho towns.
- ✓Temperature swings between river humidity and open US-95 stretches accelerate seam failure on older built-up roofs.
- ✓Access to Hells Canyon gateway properties often requires traffic plans during peak summer travel on US-95.

✓Drainage System Upgrade
Improve scuppers and internal drains on older Kellogg commercial buildings to handle spring runoff and prevent ponding.
Kellogg's commercial buildings, many tied to the mining history around the Bunker Hill Mine site, often feature older flat or low-slope roofs that must contend with repeated freeze-thaw cycles and heavy winter snow accumulation. These conditions accelerate membrane wear and create ice dam risks along eaves and drains, especially on structures near Silver Mountain Resort where foot traffic and equipment add extra stress. Proper underlayment and drainage detailing become critical to prevent water intrusion into tenant spaces during the transition from mild summers to cold, wet winters.
Metal panel systems or reinforced modified bitumen perform better here than standard shingles because they handle snow sliding and thermal movement without cracking. Crews working in Osburn or Wallace frequently encounter buildings with limited roof access due to narrow streets and steep terrain, requiring staged material lifts and careful coordination to avoid disrupting daily operations. Local code requirements in Shoshone County emphasize snow load ratings, so any replacement must account for the actual weight accumulation seen on commercial roofs each season.
