Ice dams are not a Nevada City problem so much as a California one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Nevada City winter roof services, crews handle commercial ice dam removal across Nevada County.
Sun on Cold Snow: The Nevada City Pattern
The pack at this elevation is deep enough to act as its own insulation, which means the surface melts under sun while the base stays locked. Water released at the top has to travel through and under all of it.
Aspect decides which eaves suffer. A sunny plane sheds water across a roof in Nevada City to a shaded eave that has not been above freezing for weeks, and that is where the ice builds into a wall.
Ice-barrier practice in Nevada County
High-country California codes typically call for extended ice barrier and, on metal roofing, snow guards above any door, walkway or parking area. Both exist because of what comes off these roofs.
Commercial Ice Dam Removal in Nevada City: How The Work Runs
Working around rooftop plant
HVAC curbs, exhaust fans, conduit, gas lines, solar racking and railing are all obstacles and all drift traps. The snow behind a large unit is usually the deepest on the roof and the ice under it the thickest.
Crews work around and under them rather than over, and anything running stays running.
Internal drains fail differently from gutters
A residential gutter overflows when it blocks. An internal roof drain just stops, and the water stays on the deck at depth until it finds a seam, a flashing detail or a pitch pocket.
Crews open the drain throat and then confirm flow in the leader below before calling it clear. An open drain over a frozen leader is not an open drain, and on a Nevada City building that distinction shows up as a tenant ceiling two floors down.
Scheduling around tenants
Noise, access, parking and the hours a Nevada City business can have equipment outside its door all shape when work happens. Some jobs run overnight for that reason.
Set the constraint on the call and the window gets planned around it rather than negotiated on the day.
Parapets hold the water in
A parapet is why a commercial deck ponds instead of shedding. Scuppers through the parapet are the only exit, and they are narrow, exposed on three sides and the first thing to freeze solid.
Steaming a scupper throat open is often the single highest-value twenty minutes of a commercial Nevada City call.
Roof warranties and who is allowed up there
Most commercial membranes carry a manufacturer's warranty with conditions about who may work on the roof and what methods are permitted. Snow removal is generally fine; mechanical ice removal very often is not, and the wrong contractor with the wrong tool can void cover worth considerably more than the clearing.
The warranty gets read before the roof is walked, and the method used is one the document permits.

Where We Dispatch Around Nevada City
Crews working Nevada City cover the adjoining communities on the same route — Cedar Ridge, Rough And Ready, North San Juan, Chicago Park and Penn Valley — so a storm week usually means one truck handling several addresses in Nevada County rather than separate trips.
Nearest hub towns with their own commercial ice dams pages: Grass Valley, Placerville, Olympic Valley (Palisades), Truckee, Portola, Tahoe City.
Crews cover Nevada City and the surrounding Nevada County towns through the whole season, and during a freeze event they run from first light until dark.
Most jobs do not stop at one service. Commercial Ice Dams in Nevada City often runs alongside commercial roof snow removal in Nevada City, and both get written into one scope rather than billed as separate visits.
