The ice along a roof in Ithacaline is the symptom. The cause is warm air escaping into the attic, and it is still running right now. As part of our complete Ithaca winter roof services, crews handle commercial ice dam removal across Tompkins County.
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.
Commercial Ice Dam Removal in Ithaca: How The Work Runs
Working around rooftop plant
HVAC curbs, exhaust fans, conduit, gas lines, solar racking and railing are all obstacles and all drift traps. The snow behind a large unit is usually the deepest on the roof and the ice under it the thickest.
Crews work around and under them rather than over, and anything running stays running.
Built for property managers
One contact, one scheduled window, one invoice coded the way your accounting needs it. Crews work around tenant hours where that matters, and the condition report goes to whoever has to show the board or the owner what was spent and why.
Membrane-safe means something specific
EPDM, TPO and modified bitumen all tolerate steam at low pressure and none of them tolerate chipping, scraping or a pressure washer. Crews steam the drains and scuppers open first to restore flow, then work the ponded ice, and they stay off seams and flashing details with the lance.
Mechanical units, conduit runs, solar racking and safety railing all get worked around rather than over.
What the board or the owner gets
A condition report with dated photographs, what was found, what was done and what is still a risk — in a form that can go to a board, an owner or a carrier without being rewritten.
For a managed Ithaca property that document is usually the reason the spend gets approved without a second conversation.
Insulation above the deck changes the melt pattern
A modern commercial assembly puts most of its insulation above the deck, so very little building heat reaches the membrane. That is good for energy and it means the snow that lands mostly stays - the roof does not self-clear the way an under-insulated one does.
Where dams do form on those roofs it is almost always at a thermal bridge: a parapet, a curb, a drain bowl or a line of fasteners. Those are the spots crews work first.

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 commercial ice dams pages: Cortland, Auburn, Corning, Binghamton, Geneva, Syracuse.
When a storm hits Tompkins County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
Most jobs do not stop at one service. Commercial Ice Dams in Ithaca often runs alongside commercial roof snow removal in Ithaca, and both get written into one scope rather than billed as separate visits.
