Homeowners across Strafford County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Durham winter roof services, crews handle commercial roof snow removal across Strafford County.
Durham Ice Dams and the Winter That Does Not Break
Durham 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 Strafford County
New Hampshire code has required ice-barrier underlayment at the eaves for years on new work, but plenty of housing stock predates it. On an older Durham roof the only thing between backed-up water and the deck is the shingle course itself.
Commercial Roof Snow Removal in Durham: 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 Durham roof to bare membrane costs more, takes longer and risks the roof covering for no structural benefit.
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.
Storm routes and standing contracts
Properties on a standing contract get a scheduled clear after each qualifying snowfall, with a single point of contact and a condition report per visit. For a portfolio, that means the clearing order is decided in advance by risk rather than by whoever calls first during the storm.
Sequencing so the load comes off evenly
Stripping one bay to the deck while the next still carries two feet creates exactly the unbalanced condition that overloads a member. Structures object less to a lot of weight spread evenly than to a moderate weight concentrated on one side.
Crews work in passes across the whole span, reducing everywhere before going deeper anywhere, and the sequence is set before anybody starts rather than left to whoever gets up there first.
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 Durham 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.

Neighborhoods and Towns We Reach From Durham
Crews working Durham cover the adjoining communities on the same route — Madbury, Lee, Newmarket, Barrington and Newfields — so a storm week usually means one truck handling several addresses in Strafford County rather than separate trips.
Nearest hub towns with their own commercial snow pages: Dover, Somersworth, Rochester, Portsmouth, Exeter, Derry.
Durham 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 Durham often runs alongside crane-assisted snow removal in Durham, and both get written into one scope rather than billed as separate visits.
