Why Juneau Roofs Dam Up: Altitude Sun on a Deep Pack
Altitude makes the sun stronger and the air colder at the same time. A roof in Juneau can be producing meltwater on its south face at midday while the thermometer reads well below freezing.
Aspect decides everything here. The sunny plane sheds water that the shaded plane and the shaded eave then lock up, so one side of a roof in Juneau is clear while the other carries a wall of ice.
Ice-barrier practice in Juneau County
Mountain jurisdictions across Juneau County generally require ice-barrier membrane well up the roof plane, not just the first course, along with snow retention on metal roofs above entries and walkways.
The Juneau 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.
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.
What does stop a crew is wind and lightning. Both are judgment calls made on site in Juneau, and a postponed start gets explained rather than dressed up.
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 Juneau 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.
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 Juneau 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 Juneau
Crews working Juneau cover the adjoining communities on the same route — Auke Bay and Douglas — so a storm week usually means one truck handling several addresses in Juneau County rather than separate trips.
Nearest hub towns with their own crew pages: Sitka, Ketchikan, Valdez, Girdwood, Palmer, Wasilla.
Crews cover Juneau and the surrounding Juneau County towns through the whole season, and during a freeze event they run from first light until dark.
