The ice along a roof in Cambridgeline is the symptom. The cause is warm air escaping into the attic, and it is still running right now. As part of our complete Cambridge winter roof services, crews handle commercial roof snow 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 Roof Snow Removal in Cambridge: How The Work Runs
The cost of a shutdown against the cost of a clear
Clearing a large deck is a real number and it is easy to defer. The comparison that matters is not clearing against nothing, it is clearing against the day the building is closed while an engineer inspects it - lost trade, displaced tenants, and an insurer asking what was done beforehand. Ceiling Sagging or Bulging After Snow.
The load reading is what makes that decision for you rather than a feeling about how deep the snow looks.
Reading the design load off the drawings
Where structural drawings exist they state the design ground snow load and the roof's own capacity, and that number turns the whole question from opinion into arithmetic. Measured depth and density against design capacity gives a percentage rather than an argument.
Where the drawings have been lost - common on older Cambridge stock - the conservative assumption is the code minimum of the era the building went up, which is usually well below what a modern roof would be built to.
Ponding after the clear
Taking the snow off a flat roof with frozen drains leaves meltwater with nowhere to go, and water that ponds and refreezes puts load back on a deck that was just relieved.
So drains and overflows are opened as part of the clear rather than afterwards, and the roof is left draining. A clear that stops at the snow is half a job.
Unbalanced loading is the real hazard
Snow does not settle evenly on a large deck. It piles against parapets, behind rooftop units, in the lee of a higher adjoining roof and in the valleys between bays.
Clearing has to be balanced for the same reason. Taking it all off one bay and none off the next shifts the load rather than removing it.
Reduction, not bare deck
The goal is to bring the load under threshold safely, not to scrape a roof in Cambridge clean. Clearing is balanced across the deck so load is not shifted onto one bay, drains and scuppers are opened so melt has an exit, and a cushion layer always stays on the membrane.
Where the figures call for it, crews bring in crane-assisted picks instead of adding bodies to a roof that is already carrying too much.

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 snow pages: Somerville, Arlington, Medford, Boston, Brookline, Newton.
During a cold snap Cambridge gets worked alongside the neighboring Middlesex County towns on the same route, with active interior leaks moved to the front of the list.
Most jobs do not stop at one service. Commercial Snow in Cambridge often runs alongside crane-assisted snow removal in Cambridge, and both get written into one scope rather than billed as separate visits.
