Manchester's humid continental winters bring repeated freeze-thaw cycles that push water under skylight flashing on older homes in neighborhoods like Rimmon Heights and the West Side. Many two-story wood-frame houses built before 1950 have original curb-mounted units where the lead or step flashing has corroded, allowing meltwater to track along rafters into ceilings. We carry pre-formed aluminum step flashing and high-temperature butyl tape sized for common 2x6 and 2x8 curb dimensions found in Hillsborough County stock so repairs can be completed the same day without waiting on custom orders from Nashua suppliers.
Ice dams form quickly along the Merrimack River corridor when daytime highs stay above freezing while nights drop below 20°F. Homeowners in the North End and Amoskeag Millyard often discover brown water stains after a single heavy snowfall because the skylight throat lacks insulation, creating a cold spot that draws warm attic air and melts snow against the glass. Our crews check for missing baffles and add closed-cell foam insulation around the curb before resealing to stop the cycle that repeats every winter.
Post-storm calls spike after nor'easters when wind-driven rain forces water past aged rubber gaskets on acrylic or polycarbonate domes common in East Side capes. We inspect the entire perimeter with a moisture meter rather than relying on visible drips, because water often travels laterally along the roof deck before showing inside. Temporary tarping with furring strips and 6-mil poly prevents further ceiling damage until permanent replacement can be scheduled around the owner's work hours.
Technician insight
In Manchester the thing that catches most people out with Emergency Skylight Repair is how quickly an ice dam on a West Side or Rimmon Heights roof turns a small gasket leak into ceiling plaster damage once the freeze-thaw cycle starts; the older unvented attics common here trap the meltwater right against the curb so you have to open the ceiling to dry it properly or the rot keeps spreading.
Active Leak After January Thaw in the North End
Homeowner noticed brown stains spreading across the kitchen ceiling after a mid-week warm spell. We found the skylight curb flashing had lifted where previous sealant had cracked from repeated ice expansion. We removed the damaged step flashing, rebuilt the curb with pressure-treated lumber and new aluminum profiles, added closed-cell insulation, and resealed the unit. No further leaks appeared after the next heavy snow.
