Most Hanover homeowners find out about an ice dam from the inside — a damp patch on a bedroom ceiling, or water tracking down the inside of a window frame. As part of our complete Hanover winter roof services, crews handle roof snow removal across Grafton County.
Hanover Ice Dams: What a Five-Month Snow Pack Does
The defining feature of a Grafton 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.
A long season is not a safer one. It means more freeze-thaw cycles, and each one adds a layer to the dam. By late winter the ice at a Grafton County eave can be a foot deep and locked to the shingle, with standing water sitting behind it.
Ice-barrier practice in Grafton County
Insulation depth matters at least as much as membrane in this climate, and Grafton County stock built before modern attic standards tends to be short on both. One is a code question; the other is why the dam formed.
Roof Snow Removal in Hanover: How The Work Runs
Rain on top of snow
A warm rain onto a deep pack is the loading case that puts roofs on the news. The snow absorbs the rain instead of shedding it, the drains and gutters are still frozen, and the load can climb sharply within hours while the depth barely changes. Ceiling Sagging or Bulging After Snow.
When that forecast appears over Grafton the priority order changes: large flat spans and anything already carrying a deep pack get cleared ahead of the line, before the rain rather than after it.
Wet snow, dry snow and what the weight actually is
Depth tells you very little on its own. Light powder runs around seven pounds per cubic foot; old settled snow two or three times that; the saturated layer sitting at the bottom of a pack after a thaw can approach the weight of standing water. Two roofs in Hanover under the same twenty inches can be carrying loads that differ by a factor of four.
Crews take a core and weigh it rather than guessing from the ruler, because that measurement is what decides whether a roof is near its limit or nowhere close.
Clearing the eaves is what matters
The first three to six feet above the gutter line is where dams build, because that strip of roof sits past the heated part of the house. Taking the snow off that band removes the meltwater supply before the next thaw-freeze cycle can turn it into ice.
Crews work from the ground with extended rakes wherever the pitch and height allow, and from the roof with harnesses and anchors when they do not. A cushion layer of snow is always left behind on the surface, because a rake run hard against bare shingle does its own damage.
Snow load is a structural question too
Snow is not weightless. Wet pack and drifted snow can carry serious weight per square foot, and it collects unevenly — behind dormers, against parapets, in valleys and on the lee side of a ridge. Older framing and low-slope roofs are where that shows up first as deflection.
If a roof in Hanover is already groaning, sagging between rafters or showing new cracks in interior drywall, that is a load problem and not a cosmetic one. Say so on the call and the crew treats it as urgent.
Clearing before the thaw rather than after
A warm spell is not relief. Meltwater from a deep pack has to go somewhere, and on a roof whose eaves and gutters are still frozen it goes under the shingles. The week a Hanover forecast turns mild is the week the interior leak calls start.
Taking the snow off ahead of the thaw removes the water before it has a chance to find a way in, which is a far cheaper exercise than mitigating the ceiling it would otherwise come through.

Neighborhoods and Towns We Reach From Hanover
Crews working Hanover cover the adjoining communities on the same route — Etna, West Lebanon, Lyme, Enfield and Lyme Center — so a storm week usually means one truck handling several addresses in Grafton County rather than separate trips.
Nearest hub towns with their own roof snow removal pages: Lebanon, Claremont, Franklin, Laconia, Concord, Keene.
During a cold snap Hanover gets worked alongside the neighboring Grafton County towns on the same route, with active interior leaks moved to the front of the list.
Most jobs do not stop at one service. Roof Snow Removal in Hanover often runs alongside ice dam removal in Hanover, and both get written into one scope rather than billed as separate visits.
