The ice along a roof in Mount Vernonline is the symptom. The cause is warm air escaping into the attic, and it is still running right now. As part of our complete Mount Vernon winter roof services, crews handle commercial ice dam removal across Westchester County.
Older Housing, Heavy Snow: The Westchester County Case
Coastal snow is heavy with water, and a roof in Mount Vernon 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 Westchester 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 Westchester County
Most Westchester 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.
Commercial Ice Dam Removal in Mount Vernon: 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.
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 a Mount Vernon building that distinction shows up as a tenant ceiling two floors down.
Multiple buildings on one site
Campuses, retail strips and multi-building properties get walked together and prioritized by which deck is closest to trouble, rather than worked in the order the calls came in.
One scope, one invoice, one contact. It is a meaningfully different job from nine separate ones.
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.
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.
