New Hampshire home risk profile

You're signing closing papers in January on a house outside Concord, and the inspection report mentions "past ice damming at the north eave." That's not a nitpick. Winter storms are the top hazard in New Hampshire, rated 5 out of 5 in this profile, and they cause more damage here than anything else on the list — snow load on roofs, ice dams, limbs taking out power for days, and the freeze that follows.

Flooding comes in second at 3 out of 5, and it's the one buyers underestimate. In New Hampshire, flooding usually isn't a hurricane story. It's a January thaw, a spring melt, or a stalled storm dropping several inches on ground that can't take it. Small rivers and culverts back up fast, and a basement that stayed dry for a decade can still take on water twice in one spring. Pull the FEMA flood map for the parcel before you waive anything, and price an NFIP policy through FloodSmart even if your lender doesn't require it.

The rest of the list runs low. Wildfire, earthquakes, hurricanes, drought, landslides, and severe storms each sit at 2 out of 5. Tornadoes and extreme heat sit at 1 out of 5. New Hampshire isn't a state where you brace for one catastrophic event. It's a state where the same winter shows up every year, plus a scattering of towns with real river flood history. For county-level detail, start with the New Hampshire Department of Safety, Homeland Security and Emergency Management.

If you have one weekend and one budget, I'd pull the flood map first, then ask the seller for three years of plowing, heating, and water-in-the-basement history. Roof snow load, attic insulation, and drainage matter more here than anything seismic or tropical. Read your winter-damage deductible as closely as your premium.
