Ice dams are not a Los Alamos problem so much as a New Mexico one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Los Alamos winter roof services, crews handle ice dam removal across Los Alamos County.
Sun on Cold Snow: The Los Alamos Pattern
Thin air at altitude means intense direct sun even in deep cold. A Los Alamos roof can be melting on its south face at midday in air that never gets near freezing, and all of that water has to go somewhere.
Aspect decides which eaves suffer. A sunny plane sheds water across a roof in Los Alamos 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 Los Alamos County
High-country New Mexico 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.
Ice Dam Removal in Los Alamos: How The Work Runs
Working at night and during an active storm
Freeze events do not keep office hours, and the worst leaks tend to announce themselves in the evening when the day's melt refreezes. Crews run lit, and a roof that is actively collecting snow is worked anyway, because waiting for better weather means the dam is bigger when somebody finally gets to it. Water Stain on the Ceiling in Winter.
What does stop a crew is wind and lightning. Both are judgment calls made on site in Los Alamos, and a postponed start gets explained rather than dressed up.
Why a drainage channel is not removal
Cutting a few channels through a dam so water can get past is quick and it is sometimes sold as ice dam removal. It drains the roof for as long as the channels stay open, which in a Los Alamos cold snap can be a single night before they close again.
Removing the dam means taking the ice off down to the shingle along the whole affected run, so the eave can drain the way it was built to. It takes longer and it is the only version that holds.
Steep, high and awkward Los Alamos roofs
Pitch and height change the job more than ice thickness does. A walkable ranch eave is a ladder and a lance. A three-story roof with a steep pitch means anchors, rope, staging and two people where one would otherwise do.
Crews quote on that honestly. If a property in Los Alamos needs a longer setup, it is said on the phone rather than discovered at the end of the invoice.
Why salt and ice melt make it worse
Calcium chloride opens a narrow channel and leaves the dam standing. The channel refreezes, the dam does not go anywhere, and in the meantime the runoff corrodes gutter seams, fasteners, flashing and anything growing underneath.
It is a stopgap at best. On a roof in Los Alamos with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.
What the dam has already done to the gutter and fascia
Ice expands as it forms, and a trough packed solid pushes the gutter away from the fascia a little more every cycle. By the time the dam is thick enough to leak, the hangers are often pulled, the back of the trough has lifted, and the fascia board behind it has been wet for weeks.
None of that is visible until the ice is off. It gets photographed when it appears, because a bent gutter found in February is a great deal easier to argue about with a carrier than one discovered in May.

Los Alamos County Coverage From Los Alamos
Crews working Los Alamos cover the surrounding Los Alamos County addresses on the same route, so a storm week usually means one truck handling several properties rather than separate trips.
Nearest hub towns with their own ice dam removal pages: Espanola, Santa Fe, Taos, Las Vegas, Taos Ski Valley, Angel Fire.
Coverage runs across Los Alamos and the nearby towns all winter, and capacity is surged into whichever New Mexico market the storm actually hits.
Most jobs do not stop at one service. Ice Dam Removal in Los Alamos often runs alongside water mitigation & dryout in Los Alamos, and both get written into one scope rather than billed as separate visits.
