Ice dams are not a Lancaster 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 Lancaster winter roof services, crews handle commercial ice dam removal across Lancaster County.
Older Housing, Heavy Snow: The Lancaster County Case
The maritime air is the other half of it. Temperatures in Lancaster County move either side of freezing within the same day far more often than they do inland, and every crossing moves water down the roof and locks it at the eave.
Then there is the architecture. Lancaster has a great deal of older housing with shallow eave returns, knee-wall attics and rooms built out over porches, all of which put heated air against cold deck with very little between.
Ice-barrier practice in Lancaster County
Coastal Pennsylvania jurisdictions generally require the membrane to extend past the interior wall line. On a house in Lancaster with a deep overhang that is further up the roof than a single course.
Commercial Ice Dam Removal in Lancaster: How The Work Runs
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.
Built for property managers
One contact, one scheduled window, one invoice coded the way your accounting needs it. Crews work around tenant hours where that matters, and the condition report goes to whoever has to show the board or the owner what was spent and why.
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.
Overflow scuppers are the tell
Water running out of an overflow scupper in winter means the primary drains are not taking it. On a Lancaster building that is a sign the roof is holding standing water somewhere above a frozen drain, and the load is being carried rather than shed.
Scuppers are checked first for exactly that reason, and a dry scupper above a wet roof is as informative as a running one.
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.

Where We Dispatch Around Lancaster
