Ice dams are not an Allentown problem so much as a Pennsylvania one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Allentown winter roof services, crews handle ice dam removal across Lehigh County.
Why Allentown Roofs Dam Up: Nor'easter Load and the Maritime Swing
Lehigh County gets the worst combination for ice: snow with high water content, followed by temperatures that oscillate rather than settle. The pack does not stay frozen and it does not drain.
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 Lehigh County
Ice-barrier membrane at the eaves is standard on re-roofs across coastal Pennsylvania, and many towns enforce it strictly. Homes that have not been re-roofed since that became normal practice are the ones that leak first.
Ice Dam Removal in Allentown: How The Work Runs
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. Water Stain on the Ceiling in Winter.
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 Allentown the following week.
What gets photographed, and why it matters later
Before the lance comes out, the crew shoots the dam from the ground and from the roof, the icicle line, any staining visible inside, and the specific courses where water is tracking under the shingles. Timestamps are on every frame.
That record is the whole case if a claim follows. An adjuster arriving in March sees a dry roof and a stained ceiling; the photographs are what connect the two, and they are what a maintenance-exclusion denial runs into.
Working at night and during an active storm
Freeze events do not keep office hours, and the worst leaks tend to announce themselves in the evening when the day's melt refreezes. Crews run lit, and a roof that is actively collecting snow is worked anyway, because waiting for better weather means the dam is bigger when somebody finally gets to it.
What does stop a crew is wind and lightning. Both are judgment calls made on site in Allentown, and a postponed start gets explained rather than dressed up.
What steam actually does
A steam unit delivers water at roughly 290°F at a pressure low enough to rest your hand in the plume. It cuts a channel straight through the ice and lifts the dam off in sections, right down to the shingle. The heat does the work, not force, so granules, seal strips and flashing come through untouched.
That is the whole difference between steam and the hot pressure washers often sold as steam. A pressure washer cuts ice fast because of its pressure — and that same pressure strips the granules off asphalt shingles and drives water up under the courses. One method removes ice. The other removes ice and roof.
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 Allentown with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.

Lehigh County Coverage From Allentown
Crews working Allentown cover the adjoining communities on the same route — Lehigh Valley, Whitehall, Catasauqua, Center Valley and Emmaus — so a storm week usually means one truck handling several addresses in Lehigh County rather than separate trips.
Nearest hub towns with their own ice dam removal pages: Bethlehem, Easton, Pottstown, Reading, Norristown, Pocono Pines.
Coverage runs across Allentown and the nearby towns all winter, and capacity is surged into whichever Pennsylvania market the storm actually hits.
Most jobs do not stop at one service. Ice Dam Removal in Allentown often runs alongside water mitigation & dryout in Allentown, and both get written into one scope rather than billed as separate visits.
