Kellogg sits in the Silver Valley with cold, snowy winters that dump heavy loads on flat roofs. Older homes and commercial buildings near the Bunker Hill Mine site and Kellogg City Park often have low-slope additions or original flat sections that need membranes able to handle repeated freeze-thaw cycles and drifting snow from the surrounding mountains. Proper tapered insulation and internal drains become critical because meltwater has nowhere to go when temperatures swing.
We use TPO and EPDM systems on most Kellogg jobs because they stay flexible in sub-zero conditions and resist the UV exposure that comes with mild but bright summers. When working near Silver Mountain Resort or in Osburn and Wallace, we also account for wind-driven snow that packs against parapets and HVAC curbs, a common cause of seam failure on older flat roofs. Edge details and flashing at penetrations receive extra attention since ice dams form quickly once the sun hits south-facing slopes.

Drainage is the biggest variable in Shoshone County. Many flat roofs here were built with minimal pitch, so we add crickets and secondary scuppers to move water before it refreezes. We also check for rust on older metal decks common in mining-era structures and recommend cover boards when existing insulation is saturated from past leaks.
Homeowners often overlook the weight of accumulated snow on flat sections attached to sloped roofs. We evaluate load paths and recommend reinforcement or snow guards when the roof sits below a steeper pitch that sheds snow onto the flat area.
Technician insight
In Kellogg, the thing that catches most people out with Flat Roofing is missing or undersized internal drains on older low-slope sections near the Bunker Hill Mine site. Heavy snow melts during the day then refreezes at night, and without enough outlets the water backs up under the membrane before homeowners notice.
Wallace Addition Drainage Fix
A flat-roof addition on a 1960s home in Wallace was ponding after every thaw. We found two clogged internal drains and saturated insulation from repeated freeze-thaw cycles. New tapered insulation, rebuilt drains, and a TPO overlay were installed. The roof now sheds meltwater before it can refreeze.
