The ice along a roof in Altoonaline is the symptom. The cause is warm air escaping into the attic, and it is still running right now. As part of our complete Altoona winter roof services, crews handle commercial ice dam removal across Blair County.
Wet Snow, Swinging Air: Altoona Ice Dams
Coastal snow is heavy with water, and a roof in Altoona can take a foot of it in a night. That pack is a full reservoir from the moment it lands, not something that becomes one slowly.

Older Blair County housing stock makes it worse. Shallow eave returns, knee-wall attics and additions built over unheated space all put warm air against a cold roof deck with very little insulation in between.
Ice-barrier practice in Blair County
Historic district review in parts of Blair County adds a step on materials and sometimes on color, which is worth knowing before a re-roof is scheduled rather than after the permit is refused.
Commercial Ice Dam Removal in Altoona: How The Work Runs
Internal drains fail differently from gutters
A residential gutter overflows when it blocks. An internal roof drain just stops, and the water stays on the deck at depth until it finds a seam, a flashing detail or a pitch pocket.
Crews open the drain throat and then confirm flow in the leader below before calling it clear. An open drain over a frozen leader is not an open drain, and on an Altoona building that distinction shows up as a tenant ceiling two floors down.
Parapets hold the water in
A parapet is why a commercial deck ponds instead of shedding. Scuppers through the parapet are the only exit, and they are narrow, exposed on three sides and the first thing to freeze solid.
Steaming a scupper throat open is often the single highest-value twenty minutes of a commercial Altoona call.
Overflow scuppers are the tell
Water running out of an overflow scupper in winter means the primary drains are not taking it. On an Altoona 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.
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.
