Freezes and winter cold snaps
Risk profile
New Hampshire freezes bring deep cold, heavy snow, ice dams, basements, wells, and older boilers or hydronic loops that need service before winter.
Home prep before the event
Before a freeze, insulate exposed pipes, disconnect hoses, cover hose bibs, seal crawlspace air leaks without blocking required combustion air, test heat, replace dirty filters, and learn the main water shutoff. Keep battery CO alarms working before using fireplaces, generators, or backup heat.
During-event safety
During the freeze, keep safe heat operating, open cabinet doors at vulnerable sinks, let a thin stream run only if local officials allow it, and never heat pipes with a torch. Shut off water if a pipe bursts and avoid standing water near electricity.
Post-event recovery
After a freeze loss, shut off the source, photograph burst pipes and soaked materials, remove standing water quickly, and keep receipts for plumbers, drying, and temporary heat. If an outage or statewide emergency drove the damage, document outage dates and official notices. Use FEMA's NH page at https://www.fema.gov/locations/new%20hampshire if a federal disaster is declared, and monitor New Hampshire Homeland Security and Emergency Management at https://www.hsem.dos.nh.gov/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: existing-home freeze prep is usually maintenance, but permitted repairs follow the local residential, plumbing, mechanical, and fuel-gas codes. Where adopted, IRC P2603.5 requires water, soil, and waste piping to be protected from freezing.
Flooding
Risk profile
New Hampshire flooding comes from steep watersheds, spring snowmelt, ice jams, intense rain, dam releases, and coastal surge in seacoast towns.
Home prep before the event
Before heavy rain, check the FEMA flood map, photograph contents, lift stored items, test sump pumps, add battery backup where practical, clean drains, extend downspouts, and ask whether the sewer line needs a backwater valve. Keep flood insurance documents separate from standard homeowners coverage.
During-event safety
During flooding, move up, not out through water. Do not drive across covered roads, enter a flooded basement with energized circuits, or run pumps if the discharge adds water against the foundation. Follow local evacuation and boil-water notices.
Post-event recovery
After floodwater recedes, do not start demolition until photos, high-water marks, and insurer instructions are recorded. Standard homeowners policies usually exclude flood; use NFIP or private flood coverage if you have it. Substantial-damage letters can trigger elevation or repair limits. Use FEMA's NH page at https://www.fema.gov/locations/new%20hampshire if a federal disaster is declared, and monitor New Hampshire Homeland Security and Emergency Management at https://www.hsem.dos.nh.gov/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: mapped flood work depends on FEMA Flood Insurance Rate Maps at https://msc.fema.gov/portal/home, local floodplain ordinances, NFIP substantial-damage rules, IRC R322/IBC 1612 where adopted, and ASCE 24 guidance at https://www.fema.gov/node/american-society-civil-engineers-flood-resistant-design-and-construction.
Straight-line wind storms
Risk profile
New Hampshire windstorms come from nor'easters, coastal lows, mountain gap winds, and saturated soils that make tree strikes a major home risk.
Home prep before the event
Before high-wind season, inspect roof edges, soffits, gutters, fences, trees, garage doors, and overhead service masts. Move loose furniture, grills, and trampolines before warnings arrive, and photograph exterior conditions so insurance adjusters can distinguish new storm damage from older wear.
During-event safety
During high wind, stay inside and away from windows, skylights, and rooms under large trees. Do not touch downed lines, and avoid opening garage doors or exterior doors while peak gusts are hitting the house.
Post-event recovery
After a windstorm, photograph roof slopes, gutters, siding, fences, tree impacts, and damaged service equipment before cleanup. Use emergency tarps only when safe, keep tree-removal receipts, and have electrical service masts or weatherheads inspected before reconnect. Use FEMA's NH page at https://www.fema.gov/locations/new%20hampshire if a federal disaster is declared, and monitor New Hampshire Homeland Security and Emergency Management at https://www.hsem.dos.nh.gov/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: high-wind repairs normally use the adopted IBC/IRC, ASCE 7 wind loads, manufacturer installation instructions, and local reroof or siding permit rules. Structural roof sheathing, garage doors, service masts, and connectors should be inspected before replacement.
Plan the repair before the next warning
Use this guide to prioritize inspections, then compare licensed local contractors before the emergency queue fills after the next storm, freeze, heat wave, flood, or fire.
