Commercial roofs in Lewiston must withstand the hot summers and cold winters of the local Mediterranean climate while serving buildings near the Snake River port. Structures along US-12 and US-95 often see accelerated wear from canyon winds funneled through Hells Canyon. Failures commonly appear as seam separations on low-slope systems exposed to temperature swings and moisture from the nearby Clearwater River. Work crews navigate around landmarks like the Lewiston Roundhouse and Hells Gate State Park when accessing sites in Nez Perce County.
Commercial Roofing in Lewiston — What We Handle
- ✓Wind loads from Hells Canyon require reinforced flashing on commercial buildings
- ✓River proximity demands extra moisture barriers in warm-summer conditions
- ✓Coordination with port traffic on the Snake River affects scheduling for roof replacements
Commercial Roofing Services We Offer in Lewiston
✓Commercial Flat Roof Replacement
Full tear-off and replacement of built-up or modified bitumen systems on low-slope buildings, with added insulation and tapered crickets sized for Kellogg snow loads.
✓Metal Panel Roofing Installation
Standing seam or screw-down metal systems installed on commercial structures near Silver Mountain Resort, with hidden fasteners and snow retention to handle winter accumulation.

Heat-welded TPO installed over existing or new decks on retail and office buildings in Kellogg and Wallace, providing UV resistance and quick drainage during spring melt.
✓Commercial Roof Leak Repair
Targeted seam and penetration repairs on older mining-era commercial roofs, using compatible materials that match the existing system and withstand repeated freeze cycles.
✓Snow Load Assessment and Reinforcement
On-site evaluation of commercial roof structures in Shoshone County followed by added supports or insulation upgrades when snow depths exceed typical seasonal loads.
Kellogg's commercial buildings often date to the mining boom around the Bunker Hill Mine site, with many structures in downtown and near Osburn carrying older built-up or metal roofs that struggle under repeated freeze-thaw cycles. Cold snowy winters add significant snow load, requiring crews to verify deck integrity and add proper cricket slopes or additional insulation before any membrane or panel work begins. Mild summers allow faster curing times for adhesives, but crews still schedule around sudden afternoon thunderstorms common in the Silver Valley.
Flat and low-slope roofs dominate commercial properties near Kellogg City Park and along Mullan Avenue, where poor drainage quickly turns into ice dams once temperatures drop. We evaluate existing ballast, check for rust on older metal decks, and confirm attachment patterns meet current wind-uplift expectations for the exposed terrain between Wallace and Kellogg. Material choices focus on 60-mil TPO or EPDM that handle thermal movement without cracking during the long winter.
