Why a Danvers Roof Dams Between Storms
Coastal snow is heavy with water, and a roof in Danvers can take a foot of it in a night. That pack is a full reservoir from the moment it lands, not something that becomes one slowly.
Add the architecture and the problem concentrates. Dormers, ells, knee walls and additions over porches all create pockets where warm air meets cold deck, and those are the eaves that dam first on a roof in Danvers.
Ice-barrier practice in Essex County
Coastal Massachusetts jurisdictions generally require the membrane to extend past the interior wall line. On a house in Danvers with a deep overhang that is further up the roof than a single course.
The Danvers 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.
Why the dam formed in the first place
Ice dams are a heat problem wearing a weather costume. Warm air escaping into the attic melts snow on the upper roof; that meltwater runs to the eave, which hangs past the heated envelope and stays below freezing; it refreezes there, and the ridge of ice grows a layer every cycle. Removal is the emergency fix. Before the crew leaves you will know which part of your attic is feeding it.
How long a removal actually takes
A single-story eave with a thin dam and clear gutters is often an hour or two. A two-story Danvers house with ice standing a foot deep across the front, frozen downspouts and a valley packed solid is most of a day for a two-man crew. The honest answer on the phone is a range and the reason for it, not a number designed to win the booking.
The estimate is revised out loud if the roof turns out worse than it looked from the ground, before the extra hours are worked rather than after they appear on the invoice.
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.
