Why a Philadelphia Roof Dams Between Storms
Coastal storms deliver the heaviest snow by weight. A single nor'easter can put a wet, dense pack on a roof in Philadelphia in one night, and the maritime air that follows rarely stays on one side of freezing for long.
Retrofits often made it worse rather than better. Insulation laid on an attic floor without sealing the bypasses underneath it keeps the living space warm and sends the same warm air straight to the roof deck.
Ice-barrier practice in Delaware County
In most coastal Pennsylvania towns the eave membrane requirement extends past the interior wall line rather than stopping at the first course. On a roof in Philadelphia with a deep overhang, that is further up than it sounds.
How a Philadelphia Steam Call Runs, Start to Finish
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.
Dormers, valleys and dead spots
Ice does not distribute evenly. It concentrates where two roof planes meet, behind dormers, in dead valleys that drain nowhere, and along the north face that never sees sun. Those pockets hold water deepest and leak first.
A crew working a roof in Philadelphia clears the full eave line and then goes back through the valleys and dormer pockets specifically, because clearing the easy straight run and calling it done is how a roof leaks again a week later.
Why a drainage channel is not removal
Cutting a few channels through a dam so water can get past is quick and it is sometimes sold as ice dam removal. It drains the roof for as long as the channels stay open, which in a Philadelphia cold snap can be a single night before they close again.
Removing the dam means taking the ice off down to the shingle along the whole affected run, so the eave can drain the way it was built to. It takes longer and it is the only version that holds.
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 Philadelphia the following week.

Neighborhoods and Towns We Reach From Philadelphia
Crews working Philadelphia cover the adjoining communities on the same route — Essington, Folcroft, Norwood, Prospect Park and Ridley Park — so a storm week usually means one truck handling several addresses in Delaware County rather than separate trips.
Nearest hub towns with their own crew pages: Upper Darby, King of Prussia, Norristown, West Chester, Pottstown, Reading.
Coverage runs across Philadelphia and the nearby towns all winter, and capacity is surged into whichever Pennsylvania market the storm actually hits.
