Winter in Londonderry 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 Londonderry winter roof services, crews handle crane-assisted snow removal across Rockingham County.
Why Londonderry Roofs Dam Up: Nor'easter Load and the Maritime Swing
The maritime air is the other half of it. Temperatures in Rockingham County move either side of freezing within the same day far more often than they do inland, and every crossing moves water down the roof and locks it at the eave.
The building stock compounds it. A great many Londonderry houses were built long before attic air sealing was a consideration, and the retrofits that followed often insulated the floor while leaving the bypasses wide open.
Ice-barrier practice in Rockingham County
Coastal New Hampshire jurisdictions generally require the membrane to extend past the interior wall line. On a house in Londonderry with a deep overhang that is further up the roof than a single course.
Crane-Assisted Snow Removal in Londonderry: How The Work Runs
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. Ceiling Sagging or Bulging After Snow.
On a site in Londonderry with public frontage this is usually the part that needs the most coordination and the part that gets the least credit.
Why it is often the cheaper number
Per hour a crane costs more than a crew with shovels. Per roof it frequently costs less, because a pick that takes an afternoon can replace several crew-days of hand clearing.
On a large Londonderry deck the crane is routinely both the faster and the cheaper answer, and the comparison gets shown rather than asserted.
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.
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.
Wind limits and when a pick gets postponed
Every crane has a wind chart, and a tarp full of snow is about the worst possible load to put on a hook in a gust - large surface area, light enough to sail, heavy enough to hurt. The limit is lower than people expect and it is not negotiable.
A Londonderry pick that is cancelled for wind gets rescheduled rather than argued about. The alternative is a swinging load over an occupied building.
