Middlesex County sees the same pattern every winter: snow on the roof, warm air in the attic, and a line of ice building along the eave where the two meet. As part of our complete Lexington winter roof services, crews handle commercial ice dam removal across Middlesex County.
Why Lexington Roofs Dam Up: Nor'easter Load and the Maritime Swing
Middlesex 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.

Then there is the architecture. Lexington 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 Middlesex County
Historic district review in parts of Middlesex 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 Lexington: How The Work Runs
Insulation above the deck changes the melt pattern
A modern commercial assembly puts most of its insulation above the deck, so very little building heat reaches the membrane. That is good for energy and it means the snow that lands mostly stays - the roof does not self-clear the way an under-insulated one does.
Where dams do form on those roofs it is almost always at a thermal bridge: a parapet, a curb, a drain bowl or a line of fasteners. Those are the spots crews work first.
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 Lexington call.
Scheduling around tenants
Noise, access, parking and the hours a Lexington business can have equipment outside its door all shape when work happens. Some jobs run overnight for that reason.
Set the constraint on the call and the window gets planned around it rather than negotiated on the day.
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.

Lexington Coverage and the Adjoining Communities
Crews working Lexington cover the adjoining communities on the same route — Arlington Heights, Hanscom Afb, Bedford, Winchester and North Waltham — so a storm week usually means one truck handling several addresses in Middlesex County rather than separate trips.
Nearest hub towns with their own commercial ice dams pages: Woburn, Burlington, Waltham, Arlington, Medford, Billerica.
Scheduling for Lexington tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
Most jobs do not stop at one service. Commercial Ice Dams in Lexington often runs alongside commercial roof snow removal in Lexington, and both get written into one scope rather than billed as separate visits.
