Every Longmont winter produces the same two calls: the ones who see the ice early, and the ones who see the ceiling stain first. As part of our complete Longmont winter roof services, crews handle heated roof & gutter cables across Boulder County.
Why Longmont Roofs Dam on Days It Never Thaws
At Longmont's elevation the air can stay below freezing all day while direct sun still melts the top of the snowpack. That meltwater runs down under the pack, reaches a shaded eave, and refreezes — on a day the thermometer never rose above freezing.
Aspect decides which eaves suffer. A sunny plane sheds water across a roof in Longmont 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 Boulder County
High-country Colorado 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 Longmont: How The Work Runs
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. Icicles and a Wet Ceiling.
Measured from inside the attic rather than guessed from the ground. On a house in Longmont with a deep overhang or a cantilever that distance is often further up than people expect.
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 Longmont property that gets both rarely needs an emergency call again. One that gets only cable usually needs fewer.
The electrical side
A dedicated GFCI-protected circuit, properly rated terminations and a disconnect somebody can actually reach. Not an extension cord out of a bathroom window, which is what gets found on a surprising number of existing Longmont installs.
Done properly it is an ordinary piece of exterior electrical work and it should look like one.
What shortens the life of a cable run
Self-regulating cable is generally good for a decade or more. What ends it early is ultraviolet exposure on a run left unshaded through summer, physical damage from somebody raking or shovelling over it, rodents in the gutter, and ice loading on clips that were never rated for it.
A system installed with UV-stable cable, proper clips and a note on the roof plan saying where it runs will usually outlast one that was simply stapled up in a hurry.
Commercial and multi-family runs
The same cable on a large building becomes a different exercise - several hundred feet of run, multiple circuits, a controller that something has to monitor, and a decision about who gets the alarm when a circuit fails.
Scope, circuit loading and control strategy get worked out with whoever maintains the Longmont building, because a heat-trace system nobody owns is a heat-trace system that stops working in its third winter.

Neighborhoods and Towns We Reach From Longmont
Crews working Longmont cover the adjoining communities on the same route — Hygiene, Niwot, Mead, Berthoud and Firestone — so a storm week usually means one truck handling several addresses in Boulder County rather than separate trips.
Nearest hub towns with their own heat cables pages: Erie, Boulder, Lafayette, Louisville, Loveland, Broomfield.
When a storm hits Boulder County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
Most jobs do not stop at one service. Heat Cables in Longmont often runs alongside ice dam removal in Longmont, and both get written into one scope rather than billed as separate visits.
