Winter in Merrimack 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 Merrimack winter roof services, crews handle commercial ice dam removal across Hillsborough County.

Older Housing, Heavy Snow: The Hillsborough County Case

A nor'easter can load a roof in Merrimack with heavy, wet snow overnight. Coastal air then swings the temperature either side of freezing for days, which is the exact condition that builds ice fastest.

Diagram showing how ice dams form on roofs due to inadequate insulation and poor ventilation
Heat escaping into the attic melts roof snow; the meltwater refreezes at the cold eave and the dam grows a layer every cycle.

Then there is the architecture. Merrimack has a great deal of older housing with shallow eave returns, knee-wall attics and rooms built out over porches, all of which put heated air against cold deck with very little between.

Ice-barrier practice in Hillsborough County

Most Hillsborough County towns require self-adhering ice barrier at the eaves on a re-roof permit. In a historic district there may be additional review on materials, which is worth checking before work is scheduled.

Commercial Ice Dam Removal in Merrimack: How The Work Runs

Roof warranties and who is allowed up there

Most commercial membranes carry a manufacturer's warranty with conditions about who may work on the roof and what methods are permitted. Snow removal is generally fine; mechanical ice removal very often is not, and the wrong contractor with the wrong tool can void cover worth considerably more than the clearing.

The warranty gets read before the roof is walked, and the method used is one the document permits.

Membrane-safe means something specific

EPDM, TPO and modified bitumen all tolerate steam at low pressure and none of them tolerate chipping, scraping or a pressure washer. Crews steam the drains and scuppers open first to restore flow, then work the ponded ice, and they stay off seams and flashing details with the lance.

Mechanical units, conduit runs, solar racking and safety railing all get worked around rather than over.

The pitched sections nobody plans for

Very few commercial buildings are flat all the way across. Entrance canopies, mansard faces, dormers over older frontages and the sloped transitions between roof levels all shed onto places where people walk.

Those sections behave like a residential roof and get worked like one - steam at the eave, snow guards noted where they are missing, and the pavement below cordoned while material is coming down.

Scheduling around tenants

Noise, access, parking and the hours a Merrimack business can have equipment outside its door all shape when work happens. Some jobs run overnight for that reason.

Set the constraint on the call and the window gets planned around it rather than negotiated on the day.

Parapets hold the water in

A parapet is why a commercial deck ponds instead of shedding. Scuppers through the parapet are the only exit, and they are narrow, exposed on three sides and the first thing to freeze solid.

Steaming a scupper throat open is often the single highest-value twenty minutes of a commercial Merrimack call.

FAQ

Merrimack and Hillsborough County FAQ

It is billed by the crew hour, and the rate plus a realistic time estimate are quoted on the phone before anyone is dispatched.

  • Scope drives the hours: length and thickness of the ice, roof pitch and height, and whether the gutters are frozen solid.
  • Access matters too — a three-story Merrimack roof takes longer to set up on than a ranch.
  • The invoice matches the quote. There are no surprise add-ons written on the tailgate.

Usually. The equipment needs a water supply and a place to park within hose reach, which is normally achievable even on a tight lot.

  • Hose runs of a few hundred feet are routine.
  • Street parking in a Hillsborough County residential area is generally workable.
  • Tell dispatch about access on the call so the right setup arrives.

Before the thaw rather than after it. The leak happens when the ice has water behind it, which is a day or two after the snow stops.

  • Calling during the storm is fine and often gets an earlier slot.
  • The expensive version is waiting until water appears on a ceiling.
  • Crews run across Hillsborough County from first light through a freeze event.

Yes. The dispatch area runs across Hillsborough County, and several addresses in one area are usually handled in the same run.

  • Adjoining communities are on the same route rather than treated as a separate trip.
  • Rural addresses outside the normal radius get told the travel position on the call.
  • Capacity is moved into whichever part of New Hampshire the storm actually hits.

Yes. Steam is safe on slate, cedar shake, tile and metal as well as asphalt, because it removes ice with heat rather than force.

  • Older Merrimack housing stock with original slate is exactly where chipping does the most damage.
  • Crews adjust the lance distance and dwell rather than the pressure.
  • Nothing mechanical touches the covering at any point.

Usually yes. Steam lances clear internal drains and scupper throats from the deck side, and the line below gets checked for flow before the crew calls it done. An open drain over a blocked leader is not actually open.

Yes, at the pressures used here. Heat melts ice without force, so there is nothing abrading the membrane or working at the seams. What is not safe on a membrane is a pressure washer, a chipper or any mechanical removal.
