Ice dams are not a Somersworth problem so much as a New Hampshire one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Somersworth winter roof services, crews handle commercial roof snow removal across Strafford County.
Long Winters, Layered Ice: The Strafford County Problem
A roof in Strafford County spends most of the year's coldest months under continuous load. That is a different problem from a single heavy storm, and it produces a different kind of ice.

The ice that comes off a roof in Somersworth in February is rarely one event's worth. It is a laminated record of the whole season, which is why it is thick, dense and firmly bonded to the shingle.
Ice-barrier practice in Strafford 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 Somersworth roofed a few decades ago it is frequently missing entirely.
Commercial Roof Snow Removal in Somersworth: How The Work Runs
Reduction to a threshold, not a bare deck
The goal is bringing the load under the structure's capacity safely, with a cushion layer left on the membrane throughout. Ceiling Sagging or Bulging After Snow.
Scraping a commercial Somersworth roof to bare membrane costs more, takes longer and risks the roof covering for no structural benefit.
Fall protection on a deck with no anchors
Most commercial roofs have no permanent anchor points and a parapet too low to count as a guard. Working near an unprotected edge legally requires a system, and improvising one is where people get hurt.
Crews bring mobile anchors, warning lines and whatever the layout actually needs. Where the roof cannot be worked safely at all, that gets reported to the Somersworth property manager as a finding, because it will be just as true during the next storm.
What the documentation covers
Depth and density readings, calculated load, dated photographs and a written condition report per visit.
Preventing an imminent failure is treated as loss mitigation by most carriers, and that record is what supports the position if it is ever tested.
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 Somersworth 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.
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.
