By the time a roof in Andover has a visible ridge of ice at the eave, meltwater has already been pooling behind it for several freeze-thaw cycles. As part of our complete Andover winter roof services, crews handle commercial roof snow removal across Essex County.
Wet Snow, Swinging Air: Andover Ice Dams
Coastal storms deliver the heaviest snow by weight. A single nor'easter can put a wet, dense pack on a roof in Andover in one night, and the maritime air that follows rarely stays on one side of freezing for long.
Retrofits often made it worse rather than better. Insulation laid on an attic floor without sealing the bypasses underneath it keeps the living space warm and sends the same warm air straight to the roof deck.
Ice-barrier practice in Essex County
Historic district review in parts of Essex 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 Roof Snow Removal in Andover: How The Work Runs
Storm routes for a portfolio
Properties on a standing contract get cleared on a scheduled route after each qualifying snowfall, in a priority order agreed in advance by risk rather than by who calls first. Ceiling Sagging or Bulging After Snow.
For anyone managing several Andover buildings that is the difference between a plan and a scramble.
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 Andover 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.
Reduction, not bare deck
The goal is to bring the load under threshold safely, not to scrape a roof in Andover 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.
Drains and overflows come first
Before anything else comes off, the drains, scuppers and overflow outlets get opened. Otherwise the melt from the clearing has nowhere to go and the roof trades a snow problem for a ponding one.
On a deck in Andover with internal drains that means confirming flow below, not just clearing the grate.
Why large decks carry the most risk
A long-span steel or open-web joist roof has the least margin exactly where the drift is deepest — mid-span. Snow does not settle evenly either: it piles against parapets, behind rooftop units, in the lee of higher adjoining roofs, and in valleys between bays. The average depth across the roof is not the number that matters.
Crews survey depth and density at the drift points rather than the middle of the field, and calculate the working load from that against the structure's design capacity.

Neighborhoods and Towns We Reach From Andover
Crews working Andover cover the adjoining communities on the same route — North Reading, West Boxford, Wilmington, Boxford and Middleton — so a storm week usually means one truck handling several addresses in Essex County rather than separate trips.
Nearest hub towns with their own commercial snow pages: North Andover, Lawrence, Tewksbury, Methuen, Lowell, Billerica.
Coverage runs across Andover and the nearby towns all winter, and capacity is surged into whichever Massachusetts market the storm actually hits.
Most jobs do not stop at one service. Commercial Snow in Andover often runs alongside crane-assisted snow removal in Andover, and both get written into one scope rather than billed as separate visits.
