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.
How a Durham Steam Call Runs, Start to Finish
Nothing gets touched until the roof has been walked and photographed. The crew finds every dam, locates where water is getting in, shows you, and gives you the crew-hour rate and a time estimate before the equipment comes off the truck.
Removal then works from the worst point outward, so water starts draining early rather than at the end. Gutters and downspouts frozen solid get steamed through in the same visit — leaving them means the eave dams again within days.
How long a removal actually takes
A single-story eave with a thin dam and clear gutters is often an hour or two. A two-story Durham house with ice standing a foot deep across the front, frozen downspouts and a valley packed solid is most of a day for a two-man crew. The honest answer on the phone is a range and the reason for it, not a number designed to win the booking.
The estimate is revised out loud if the roof turns out worse than it looked from the ground, before the extra hours are worked rather than after they appear on the invoice.
Working at night and during an active storm
Freeze events do not keep office hours, and the worst leaks tend to announce themselves in the evening when the day's melt refreezes. Crews run lit, and a roof that is actively collecting snow is worked anyway, because waiting for better weather means the dam is bigger when somebody finally gets to it.
What does stop a crew is wind and lightning. Both are judgment calls made on site in Durham, and a postponed start gets explained rather than dressed up.
Why the gutter has to be cleared in the same visit
A dam sitting above a gutter packed solid with ice is only half the problem. Clear the eave and leave the trough frozen, and the next day's meltwater has nowhere to run — it backs up onto the roof and the dam rebuilds from the bottom.
Crews steam the trough and the downspout through to daylight on the same visit. It adds time, which is why the hour estimate given on the phone accounts for it, and it is the difference between a fix and a repeat visit in Durham the following week.

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 crew pages: Dover, Somersworth, Rochester, Portsmouth, Exeter, Derry.
Crews cover Durham and the surrounding Strafford County towns through the whole season, and during a freeze event they run from first light until dark.
