Ice dams are not a Lebanon 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 Lebanon winter roof services, crews handle commercial roof snow removal across Grafton County.
Long Winters, Layered Ice: The Grafton County Problem
Lebanon holds snow. In a normal winter the pack that lands in December is still on the roof in February, which means the eave spends months below freezing while the attic underneath stays heated.

Ice built this way is dense and bonded. It is not the brittle shell that comes off a mild-climate roof in one piece - it is layered, hard and locked to the shingle, which is exactly why mechanical removal does so much damage here.
Ice-barrier practice in Grafton 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 Lebanon roofed a few decades ago it is frequently missing entirely.
Commercial Roof Snow Removal in Lebanon: How The Work Runs
What the documentation covers
Depth and density readings, calculated load, dated photographs and a written condition report per visit. Ceiling Sagging or Bulging After Snow.
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 Lebanon 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.
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 Lebanon property manager as a finding, because it will be just as true during the next storm.
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.
Scraping a commercial Lebanon roof to bare membrane costs more, takes longer and risks the roof covering for no structural benefit.

Neighborhoods and Towns We Reach From Lebanon
Crews working Lebanon cover the adjoining communities on the same route — West Lebanon, Etna, Plainfield, Enfield and Meriden — so a storm week usually means one truck handling several addresses in Grafton County rather than separate trips.
Nearest hub towns with their own commercial snow pages: Hanover, Claremont, Franklin, Laconia, Concord, Keene.
Lebanon sits inside the regular New Hampshire service area, so a crew is usually scheduled the same day or the following morning.
Most jobs do not stop at one service. Commercial Snow in Lebanon often runs alongside crane-assisted snow removal in Lebanon, and both get written into one scope rather than billed as separate visits.
