A St. Johnsbury roof can look fine from the driveway and still be backing water under the shingles at the eave, where nobody can see it. As part of our complete St. Johnsbury winter roof services, crews handle ice dam removal across Caledonia County.
Long Winters, Layered Ice: The Caledonia County Problem
The defining feature of a Caledonia County winter is persistence. It is not one storm, it is a continuous load sitting on the roof from late fall through to a spring thaw.

Every mild afternoon through that stretch releases a little meltwater, and every cold night sets it at the overhang. Done fifty times, that is how an eave ends up carrying several hundred pounds of ice by March.
Ice-barrier practice in Caledonia County
In the colder Vermont jurisdictions the membrane requirement extends well up the roof plane rather than stopping at the first course, precisely because the ice here does not stay near the edge.
Ice Dam Removal in St. Johnsbury: How The Work Runs
Why the gutter has to be cleared in the same visit
A dam sitting above a gutter packed solid with ice is only half the problem. Clear the eave and leave the trough frozen, and the next day's meltwater has nowhere to run — it backs up onto the roof and the dam rebuilds from the bottom. Water Stain on the Ceiling in Winter.
Crews steam the trough and the downspout through to daylight on the same visit. It adds time, which is why the hour estimate given on the phone accounts for it, and it is the difference between a fix and a repeat visit in St. Johnsbury the following week.
Steep, high and awkward St. Johnsbury roofs
Pitch and height change the job more than ice thickness does. A walkable ranch eave is a ladder and a lance. A three-story roof with a steep pitch means anchors, rope, staging and two people where one would otherwise do.
Crews quote on that honestly. If a property in St. Johnsbury needs a longer setup, it is said on the phone rather than discovered at the end of the invoice.
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 St. Johnsbury with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.
Access, ladders and what the crew needs on site
Steam equipment needs somewhere to park within hose reach, and ladders need footing that is not a buried flower bed or a sheet of ice. Clearing a path to the affected eave, moving vehicles off the driveway and unlocking a side gate takes ten minutes and saves considerably more than that on the clock.
Where the only access is through a neighbor's property, that conversation is worth having before the crew is in the street rather than while it waits.
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.

Where We Dispatch Around St. Johnsbury

Nearest hub towns with their own ice dam removal pages: Barre, Montpelier, Stowe, Williston, Essex, Hartford.
Scheduling for St. Johnsbury tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
Most jobs do not stop at one service. Ice Dam Removal in St. Johnsbury often runs alongside water mitigation & dryout in St. Johnsbury, and both get written into one scope rather than billed as separate visits.
