If you are in Goffstown watching icicles grow along the gutter line, what you are really watching is water that no longer has anywhere to drain. As part of our complete Goffstown winter roof services, crews handle commercial ice dam removal across Hillsborough County.
Long Winters, Layered Ice: The Hillsborough County Problem
The defining feature of a Hillsborough County winter is persistence. It is not one storm, it is a continuous load sitting on the roof from late fall through to a spring thaw.

Every mild afternoon through that stretch releases a little meltwater, and every cold night sets it at the overhang. Done fifty times, that is how an eave ends up carrying several hundred pounds of ice by March.
Ice-barrier practice in Hillsborough County
Because the ice here does not stay near the edge, the New Hampshire requirement generally runs the membrane well up the roof plane. On a house in Goffstown roofed a few decades ago it is frequently missing entirely.
Commercial Ice Dam Removal in Goffstown: How The Work Runs
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.
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.
Overflow scuppers are the tell
Water running out of an overflow scupper in winter means the primary drains are not taking it. On a Goffstown 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.
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.
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.
