Winter in Hanover does not need a record storm to put water inside a house. It needs a roof with snow on it, an attic leaking heat, and one cold night. As part of our complete Hanover winter roof services, crews handle roof shoveling 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 Shoveling in Hanover: How The Work Runs
Cutting in layers rather than scraping
Crews cut the pack into blocks and lift them, leaving a cushion layer behind. The blade never touches the roof surface. That is the whole technique and it is why a shovelled roof looks untouched afterwards. Ceiling Sagging or Bulging After Snow.
Scraping to bare membrane or bare shingle is what damages a roof, and it is what a well-meaning homeowner with a steel shovel does on the first pass.
The last two inches stay on
Crews deliberately leave a thin layer of snow across the covering rather than scraping to a bare surface. That layer is what keeps the shovel off the shingle, the membrane and the seams, and it weighs almost nothing compared with the pack above it.
A roof shovelled to bare deck in Hanover has usually been damaged somewhere, even if it does not show until the next rain. Reduction is the goal; bare is not.
Shoveling and steaming together
On a roof that already has a dam, shoveling and steaming usually happen in the same visit: the pack comes off first so the crew can see and reach the ice, then the dam gets steamed off the eave. Doing it in that order means less steam time, which usually means a smaller invoice.
Working around what is up there
Rooftop units, exhaust fans, conduit runs, gas lines, solar racking, skylights and safety railing all have to be cleared around rather than over. The drift shadow behind a unit is usually the deepest snow on the roof.
Skylights in particular get flagged and worked around deliberately — a shovel through cold glass is a bad afternoon for everyone.
Anchors, rope and why this is not a DIY job
Every crew member on a pitched roof is tied to a rated anchor. On ice over shingle, footing is unreliable in a way that is hard to appreciate from the ground.
Roof falls are the most common serious winter injury in this trade and they happen to people who have done it for years. A Hanover homeowner in work boots on a January roof is taking a risk out of all proportion to the money saved.

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 shoveling pages: Lebanon, Claremont, Franklin, Laconia, Concord, Keene.
Hanover 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. Roof Shoveling in Hanover often runs alongside roof snow removal in Hanover, and both get written into one scope rather than billed as separate visits.
