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.
How a Greenwich Steam Call Runs, Start to Finish
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 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.
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 Greenwich the following week.
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 Greenwich with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.
What the dam has already done to the gutter and fascia
Ice expands as it forms, and a trough packed solid pushes the gutter away from the fascia a little more every cycle. By the time the dam is thick enough to leak, the hangers are often pulled, the back of the trough has lifted, and the fascia board behind it has been wet for weeks.
None of that is visible until the ice is off. It gets photographed when it appears, because a bent gutter found in February is a great deal easier to argue about with a carrier than one discovered in May.

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 crew pages: Stamford, Darien, New Canaan, Norwalk, Westport, Ridgefield.
Greenwich sits inside the regular Connecticut service area, so a crew is usually scheduled the same day or the following morning.
