Why Reading Roofs Dam Up: Nor'easter Load and the Maritime Swing
Berks 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 Berks County
Most Berks 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.
What a Crew Does on a Reading Roof
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.
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 the dam formed in the first place
Ice dams are a heat problem wearing a weather costume. Warm air escaping into the attic melts snow on the upper roof; that meltwater runs to the eave, which hangs past the heated envelope and stays below freezing; it refreezes there, and the ridge of ice grows a layer every cycle. Removal is the emergency fix. Before the crew leaves you will know which part of your attic is feeding it.
If water already got inside
Taking the ice off stops new water. It does nothing about what is already in the insulation, the ceiling and the walls of a Reading home.
The same company handles the rest: water mitigation and dryout, mold remediation where the water has led to growth, the interior repair, and the roof where the dam damaged it, all documented on one insurance claim.

Berks County Coverage From Reading
Crews working Reading cover the adjoining communities on the same route — Temple, Leesport, Mohnton, Blandon and Limekiln — so a storm week usually means one truck handling several addresses in Berks County rather than separate trips.
Nearest hub towns with their own crew pages: Pottstown, Lebanon, Lancaster, Allentown, West Chester, King of Prussia.
Scheduling for Reading 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 Reading, call (888) 561-9664 rather than filling in a form — the phone is faster and leaks jump the line.
