Why Ithaca Roofs Dam Up: Nor'easter Load and the Maritime Swing
The maritime air is the other half of it. Temperatures in Tompkins County move either side of freezing within the same day far more often than they do inland, and every crossing moves water down the roof and locks it at the eave.
Older Tompkins County housing stock makes it worse. Shallow eave returns, knee-wall attics and additions built over unheated space all put warm air against a cold roof deck with very little insulation in between.
Ice-barrier practice in Tompkins County
Ice-barrier membrane at the eaves is standard on re-roofs across coastal New York, and many towns enforce it strictly. Homes that have not been re-roofed since that became normal practice are the ones that leak first.
How We Work an Ithaca Ice Dam
The first pass is assessment: eaves, valleys, gutter line and any interior staining, all photographed with timestamps. You see what the crew sees, and the rate and likely hours are agreed before work begins.
Steam then takes the dam off in sections, prioritizing wherever water is actively backing up behind it. The gutter trough and downspout are cleared through to daylight on the same visit, because a clear eave over a frozen gutter is a temporary fix.
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 Ithaca 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.
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.

Ithaca Coverage and the Adjoining Communities
Crews working Ithaca cover the adjoining communities on the same route — Etna, Freeville, Jacksonville, Newfield and Brooktondale — so a storm week usually means one truck handling several addresses in Tompkins County rather than separate trips.
Nearest hub towns with their own crew pages: Cortland, Auburn, Corning, Binghamton, Geneva, Syracuse.
Scheduling for Ithaca tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
Water through a ceiling in Ithaca is a same-day call, not a next-week one. (888) 561-9664 goes straight to dispatch.
