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 heated roof & gutter cables 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.
Heated Roof & Gutter Cables in Los Alamos: How The Work Runs
Fastening without putting holes in the roof
Clips and standoffs designed for the job, adhered or clipped to the shingle edge. Never a fastener driven through the covering, and never left loose to abrade in the wind. Icicles and a Wet Ceiling.
The failures that give heat cable a bad name are nearly all installation failures of this kind rather than product failures.
Cable is the backstop, not the cure
The underlying cause of an ice dam is heat leaving the house. Air sealing the attic, fixing crushed baffles and topping up insulation addresses that; cable manages what is left.
A Los Alamos property that gets both rarely needs an emergency call again. One that gets only cable usually needs fewer.
Valleys, downspouts and the parts people forget
A zig-zag along the eave with nothing in the valley and nothing down the downspout produces a melted strip of roof draining into a solid block of ice. The water still has nowhere to go, and the dam just forms somewhere slightly different.
A system that works runs the full path: eave, valley, gutter trough and all the way down the downspout to daylight. The downspout run is the piece most often left out and the piece most often responsible for the system not working.
Why most cable installations underperform
Not because the cable is bad. Because the path is incomplete. A zig-zag along the first few feet of eave that does not continue into the gutter and down the leader melts a channel that ends in a block of ice.
The water has to get all the way to the ground. On a Los Alamos install that means eave, valleys, trough and downspout traced as one continuous path, and it is the single thing that separates a system that works from one that does not.
Sizing the eave zig-zag to the cold overhang
The zig-zag has to extend far enough up the roof to cover the part of the deck that sits past the heated wall line, because that is the part that stays below freezing.
Measured from inside the attic rather than guessed from the ground. On a house in Los Alamos with a deep overhang or a cantilever that distance is often further up than people expect.
What you get in Los Alamos

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 heat cables pages: Espanola, Santa Fe, Taos, Las Vegas, Taos Ski Valley, Angel Fire.
Crews cover Los Alamos and the surrounding Los Alamos 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. Heat Cables in Los Alamos often runs alongside ice dam removal in Los Alamos, and both get written into one scope rather than billed as separate visits.
