Ice dams are not an Andover problem so much as a Massachusetts one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Andover winter roof services, crews handle commercial ice dam 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 Ice Dam Removal in Andover: How The Work Runs
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.
Flat roofs fail differently
A pitched residential roof dams at the eave. A commercial deck dams at its drainage: frozen scuppers, iced-over internal drains, and ponding that refreezes into a sheet across the low spots. Water then sits on the membrane at depth, finds a seam or a flashing detail, and comes through into the tenant space below.
Parapet walls make it worse by holding the melt on the deck instead of letting it run off an edge. By the time it shows up as a ceiling tile stain in an Andover unit, there is usually standing water up there.
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 an Andover building that distinction shows up as a tenant ceiling two floors down.
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.

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 ice dams 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 Ice Dams in Andover often runs alongside commercial roof snow removal in Andover, and both get written into one scope rather than billed as separate visits.
