A Durham roof can look fine from the driveway and still be backing water under the shingles at the eave, where nobody can see it. As part of our complete Durham winter roof services, crews handle crane-assisted 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.
Crane-Assisted Snow Removal in Durham: How The Work Runs
What it protects
Avoiding a structural failure is the obvious part. The less obvious part is that most carriers treat preventing an imminent collapse as loss mitigation, which is a very different conversation from a claim filed after the deck comes down. Weights, depths and dates are documented throughout for exactly that reason. Ceiling Sagging or Bulging After Snow.
How a pick actually works
Rip-stop tarps are laid out and anchored on the deck, crews load them, and the boom lifts each loaded tarp clear and sets it down in a designated drop zone on the ground. Outrigger pads are placed on frozen ground rated for the load, and a pedestrian exclusion zone is set and marshalled for the whole operation.
It is a planned lift, not an improvisation. Site access, swing radius, overhead lines, drop zone and ground bearing all get walked before the first tarp goes down.
The arithmetic that justifies a crane
Snow weight is depth times density times area. Fresh powder is light; settled wet pack can be several times heavier for the same depth, and drifted pack heavier again.
Crews take depth and density readings at the drift points on a roof in Durham, work out the load, and compare it to the structure's design capacity. A crane gets mobilised when that number says hand clearing cannot win the race against the next storm.
Keeping people clear of the swing
A loaded tarp overhead is a serious exclusion zone. Pedestrian and vehicle routes get marshalled for the whole operation, and on an occupied building that means talking to whoever controls the doors before the first lift.
On a site in Durham with public frontage this is usually the part that needs the most coordination and the part that gets the least credit.
What goes in the tarp and what does not
A pick lifts loose and broken snow. It does not lift a solid sheet of ice frozen to the membrane, and trying to make it do so is how a tarp takes the roof covering with it.
So the sequence is crews cutting and breaking the pack into liftable material, the crane moving it, and steam dealing with whatever is bonded to the surface. The crane is the transport, not the demolition.

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 crane snow removal pages: Dover, Somersworth, Rochester, Portsmouth, Exeter, Derry.
Scheduling for Durham tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
Most jobs do not stop at one service. Crane Snow Removal in Durham often runs alongside commercial roof snow removal in Durham, and both get written into one scope rather than billed as separate visits.
