By the time a roof in Greenwich has a visible ridge of ice at the eave, meltwater has already been pooling behind it for several freeze-thaw cycles. As part of our complete Greenwich winter roof services, crews handle commercial ice dam removal across Fairfield County.
Why Greenwich Roofs Dam Up: Nor'easter Load and the Maritime Swing
The maritime air is the other half of it. Temperatures in Fairfield 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.
Then there is the architecture. Greenwich has a great deal of older housing with shallow eave returns, knee-wall attics and rooms built out over porches, all of which put heated air against cold deck with very little between.
Ice-barrier practice in Fairfield County
Most Fairfield County towns require self-adhering ice barrier at the eaves on a re-roof permit. In a historic district there may be additional review on materials, which is worth checking before work is scheduled.
Commercial Ice Dam Removal in Greenwich: How The Work Runs
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 Greenwich property that document is usually the reason the spend gets approved without a second conversation.
Internal drains fail differently from gutters
A residential gutter overflows when it blocks. An internal roof drain just stops, and the water stays on the deck at depth until it finds a seam, a flashing detail or a pitch pocket.
Crews open the drain throat and then confirm flow in the leader below before calling it clear. An open drain over a frozen leader is not an open drain, and on a Greenwich building that distinction shows up as a tenant ceiling two floors down.
Roof warranties and who is allowed up there
Most commercial membranes carry a manufacturer's warranty with conditions about who may work on the roof and what methods are permitted. Snow removal is generally fine; mechanical ice removal very often is not, and the wrong contractor with the wrong tool can void cover worth considerably more than the clearing.
The warranty gets read before the roof is walked, and the method used is one the document permits.
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.
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.

Where We Dispatch Around Greenwich
Crews working Greenwich cover the adjoining communities on the same route — Cos Cob, Riverside and Old Greenwich — so a storm week usually means one truck handling several addresses in Fairfield County rather than separate trips.
Nearest hub towns with their own commercial ice dams pages: Stamford, Darien, New Canaan, Norwalk, Westport, Ridgefield.
Coverage runs across Greenwich and the nearby towns all winter, and capacity is surged into whichever Connecticut market the storm actually hits.
Most jobs do not stop at one service. Commercial Ice Dams in Greenwich often runs alongside commercial roof snow removal in Greenwich, and both get written into one scope rather than billed as separate visits.
