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.
The Longmont Dispatch Process, Step by Step
Nothing gets touched until the roof has been walked and photographed. The crew finds every dam, locates where water is getting in, shows you, and gives you the crew-hour rate and a time estimate before the equipment comes off the truck.
Removal then works from the worst point outward, so water starts draining early rather than at the end. Gutters and downspouts frozen solid get steamed through in the same visit — leaving them means the eave dams again within days.
Dormers, valleys and dead spots
Ice does not distribute evenly. It concentrates where two roof planes meet, behind dormers, in dead valleys that drain nowhere, and along the north face that never sees sun. Those pockets hold water deepest and leak first.
A crew working a roof in Longmont clears the full eave line and then goes back through the valleys and dormer pockets specifically, because clearing the easy straight run and calling it done is how a roof leaks again a week later.
What happens after the ice is off
Once the eave is clear and water is draining, the crew walks the interior with you where there is visible damage and says plainly whether it needs drying. Wet insulation and a damp ceiling cavity do not resolve themselves in a cold Longmont February.
If it does, that is a separate scope and it gets written separately — nobody is upsold a dryout on the strength of one damp patch.
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 Longmont 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.

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 crew pages: Erie, Boulder, Lafayette, Louisville, Loveland, Broomfield.
Crews cover Longmont and the surrounding Boulder County towns through the whole season, and during a freeze event they run from first light until dark.
