Long Winters, Layered Ice: The Penobscot County Problem
A roof in Penobscot County spends most of the year's coldest months under continuous load. That is a different problem from a single heavy storm, and it produces a different kind of ice.

Ice built this way is dense and bonded. It is not the brittle shell that comes off a mild-climate roof in one piece - it is layered, hard and locked to the shingle, which is exactly why mechanical removal does so much damage here.
Ice-barrier practice in Penobscot County
Insulation depth matters at least as much as membrane in this climate, and Penobscot County stock built before modern attic standards tends to be short on both. One is a code question; the other is why the dam formed.
The Bangor 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.
What steam actually does
A steam unit delivers water at roughly 290°F at a pressure low enough to rest your hand in the plume. It cuts a channel straight through the ice and lifts the dam off in sections, right down to the shingle. The heat does the work, not force, so granules, seal strips and flashing come through untouched.
That is the whole difference between steam and the hot pressure washers often sold as steam. A pressure washer cuts ice fast because of its pressure — and that same pressure strips the granules off asphalt shingles and drives water up under the courses. One method removes ice. The other removes ice and roof.
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 Bangor 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 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 Bangor with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.

Where We Dispatch Around Bangor
Crews working Bangor cover the adjoining communities on the same route — Brewer, Orrington, Hampden, Stillwater and Eddington — so a storm week usually means one truck handling several addresses in Penobscot County rather than separate trips.
Nearest hub towns with their own crew pages: Orono, Ellsworth, Bar Harbor, Camden, Waterville, Augusta.
Bangor sits inside the regular Maine service area, so a crew is usually scheduled the same day or the following morning.
