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.
What a Crew Does on an Allentown Roof
Crews walk the eaves, valleys and gutter line first and photograph every dam and every point where water is tracking inside, before touching anything. You get shown what they found and quoted the crew-hour rate before work starts.
Then the ice comes off with low-pressure steam, starting wherever water is actively backing up so drainage opens early. Frozen gutters and downspouts are cleared in the same visit, because a cleared eave above a solid block of ice in the gutter dams again on the next cold night.
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 Allentown 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.
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.
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 an Allentown 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.

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 crew pages: Bethlehem, Easton, Pottstown, Reading, Norristown, Pocono Pines.
Scheduling for Allentown tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
If water is already inside a property in Allentown, call (888) 561-9664 rather than filling in a form — the phone is faster and leaks jump the line.
