Every Cambridge winter produces the same two calls: the ones who see the ice early, and the ones who see the ceiling stain first. As part of our complete Cambridge winter roof services, crews handle commercial ice dam removal across Middlesex County.
Older Housing, Heavy Snow: The Middlesex County Case
Coastal snow is heavy with water, and a roof in Cambridge 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 Middlesex 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 Middlesex County
Ice-barrier membrane at the eaves is standard on re-roofs across coastal Massachusetts, and many towns enforce it strictly. Homes that have not been re-roofed since that became normal practice are the ones that leak first.
Commercial Ice Dam Removal in Cambridge: How The Work Runs
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.
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 Cambridge call.
Overflow scuppers are the tell
Water running out of an overflow scupper in winter means the primary drains are not taking it. On a Cambridge 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.
Roof warranties and who is allowed up there
Most commercial membranes carry a manufacturer's warranty with conditions about who may work on the roof and what methods are permitted. Snow removal is generally fine; mechanical ice removal very often is not, and the wrong contractor with the wrong tool can void cover worth considerably more than the clearing.
The warranty gets read before the roof is walked, and the method used is one the document permits.
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.

Middlesex County Coverage From Cambridge
Crews working Cambridge cover the adjoining communities on the same route — New Town, Watertown, Allston, Brighton and Belmont — 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: Somerville, Arlington, Medford, Boston, Brookline, Newton.
When a storm hits Middlesex County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
Most jobs do not stop at one service. Commercial Ice Dams in Cambridge often runs alongside commercial roof snow removal in Cambridge, and both get written into one scope rather than billed as separate visits.
