Homeowners across Delaware County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Philadelphia winter roof services, crews handle commercial ice dam removal across Delaware County.
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.
Commercial Ice Dam Removal in Philadelphia: How The Work Runs
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.
Scheduling around tenants
Noise, access, parking and the hours a Philadelphia business can have equipment outside its door all shape when work happens. Some jobs run overnight for that reason.
Set the constraint on the call and the window gets planned around it rather than negotiated on the day.
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.
The pitched sections nobody plans for
Very few commercial buildings are flat all the way across. Entrance canopies, mansard faces, dormers over older frontages and the sloped transitions between roof levels all shed onto places where people walk.
Those sections behave like a residential roof and get worked like one - steam at the eave, snow guards noted where they are missing, and the pavement below cordoned while material is coming down.
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.

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 commercial ice dams pages: Upper Darby, King of Prussia, Norristown, West Chester, Pottstown, Reading.
Crews cover Philadelphia and the surrounding Delaware County towns through the whole season, and during a freeze event they run from first light until dark.
Most jobs do not stop at one service. Commercial Ice Dams in Philadelphia often runs alongside commercial roof snow removal in Philadelphia, and both get written into one scope rather than billed as separate visits.
