Ski Home and High-Value Home Insurance in the White Mountains, NH

By Jon Merwin, Founder and CEO, Licensed Insurance Advisor. Updated October 30, 2026.

What does a ski house or high-value home in the White Mountains need from its insurance? A dwelling limit that reflects what it costs to rebuild on a mountain lot, coverage that holds up under a heavy snow year, clear terms for a house that sits empty between weekends, and a flood plan for homes near the Saco, the Pemigewasset and their brooks. We’re Portsmouth Atlantic Insurance, a family-owned independent agency founded in 2005, and we put 40+ carriers to work for ski houses, second homes and larger primary homes from North Conway and Jackson to Lincoln and Waterville Valley. Phone (603) 431-4020 to have the house, the umbrella and the sleds looked at as one household.

Which White Mountains homes count as high-value?

Up north, a house earns that label less from its sale value than from what it would take to build again on the same lot. Typical examples are timber-frame and post-and-beam houses near the ski areas, slopeside and ski-in homes, larger houses on view lots above North Conway and Jackson, and family compounds with a main house, a guest house and a barn or garage. Many are second homes. A growing number are lived in year-round by owners who now work remotely.

Two things make these houses different to insure from a Seacoast or southern New Hampshire home. They often sit at the end of long, steep driveways, some distance from a fire station and hydrant. And they are built with heavier timber, custom stone and big glass, which costs more to replace and takes longer to source after a loss. Both affect which carriers will write the house and at what terms.

The White Mountains, area by area

Snow, ice dams and roof collapse

Snow is the hazard that separates a mountain house from almost any other New Hampshire home. Conway’s hazard mitigation plan describes the winter of 2008, when heavy accumulation led to several building collapses in town, and an April 2007 Nor’easter that brought heavy wet snow and a few roof collapses. Ice storms are noted as a particular risk above about 1,500 feet.

Most homeowners policies we see treat the weight of snow and ice as a covered cause of collapse, but the details matter. Ice dams can push meltwater under shingles and into ceilings and walls. Deductibles differ, and some policies treat certain outbuildings, decks or awnings differently from the house. We read each carrier’s collapse and water-damage wording side by side, and we will ask who clears the roof and the decks when you are not there. Our post on snow and ice damage insurance in the Northeast walks through how these claims usually play out.

For new construction and big additions, the snow load your engineer designs to now comes from ASCE 7-22 under the 2024 code. Structural Engineers of New Hampshire points out that not every New Hampshire town has a local code enforcement officer, and that the State Fire Marshal’s Office enforces the code where there is none. Keep your engineer’s letter and permits with your policy papers. Underwriters sometimes ask for them on custom or timber-frame homes.

Rivers, brooks and spring flooding

Mountain flooding looks different from coastal flooding. It comes fast, from heavy rain on snowpack, overwhelmed culverts and ice jams. Conway’s plan calls the March 1953 flood on the Saco the largest in over 100 years, caused by snowmelt and heavy rain. It records Tropical Storm Irene in 2011 as a federal disaster that caused significant damage in Transvale Acres, evacuations and a shelter that stayed open for 10 days, after which the town bought out 13 properties there. It also notes a 2011 ice jam at Abenaki Drive that raised the Saco 20 feet above its normal level.

Rising water is excluded from homeowners coverage, so flood is a separate decision. When we place a new NFIP policy, it is written through Selective. FloodSmart lists the federal program’s maximums as $250,000 for the building and $100,000 for contents, with a standard 30-day wait before a new policy starts unless a loan closing triggers it. That ceiling is low for a custom mountain house near a river, so we also look at private flood from Neptune, Flow Flood, Aon Edge, Beyond Floods, CatCoverage and TFIA (The Flood Insurance Agency). Look up the zone for your address on the FEMA Flood Map Service Center. Our flood insurance page explains the basics.

Distance to fire protection and wildfire

Many view lots and ski homes sit up long private roads, some distance from the nearest station. Carriers look closely at how far the house is from a fire station and a hydrant or other water source, whether the driveway is plowed and passable for an engine, and whether the alarms are monitored. Conway’s plan also maps the slopes of its mountains as the areas most prone to wildfire and structure fire, especially where homes meet wooded land.

Monitored fire and low-temperature alarms, a cleared defensible space, a plowing contract and a chimney sweep record for wood stoves and fireplaces all widen the carrier list. If the house is hard to reach in winter, tell us up front. It is better to match the house with the right carrier from the start than to learn about an eligibility problem after a claim.

Weekend use, empty weeks and rentals

A ski house is often used on weekends and holiday weeks and closed the rest of the time. That is a normal second-home risk, but frozen pipes are the most common big claim on these houses. Carriers will ask how the heat stays on, whether there is a low-temperature alarm and automatic water shutoff, and who checks the house after a storm or a power outage. Vacancy and unoccupancy wording is where many ski-house claims get decided; the vacant home insurance post explains the difference, and our New Hampshire second home insurance guide covers seasonal houses statewide.

Renting the house during ski season or foliage weekends changes the policy. Before the first booking, let us know the number of rental nights, the booking site and who meets guests and clears snow. A few carriers will add limited rental to a homeowners policy by endorsement; others move the house to a dwelling or short-term rental form. If you own a ski house across the river in Vermont too, our Vermont ski house insurance page covers that state.

Snowmobiles, trucks, collector cars and umbrella liability

A mountain household usually has more than a house to insure. Snowmobiles and ATVs ridden on trails need their own policies, which we explain on our New Hampshire snowmobile insurance and New Hampshire ATV insurance pages. A hot tub on the deck, a pond, icy steps and a steady rotation of ski friends or renters are the reasons we usually suggest a personal umbrella over the home and autos; New Hampshire umbrella insurance shows how it sits on top. Hagerty is part of our comparison for a collector car stored in a mountain garage, and the collector car and high-value auto pages for New Hampshire go deeper.

Carriers we compare for White Mountains homes

For a mountain house, the shortlist depends on the rebuild figure, how the house is used and how far it sits from fire protection. Andover is an option for many New Hampshire homes, with a lower limit in areas with limited fire protection. Hanover tops out at $2 million. Openly writes New Hampshire homes up to $5 million, and National General is another option for bigger houses. Chubb and Cincinnati have no dwelling ceiling. Second-home rules, rental rules, wood stove questions and fire-station distance all vary from one carrier to the next, which is why we confirm eligibility on your specific address first. Our Chubb review and the carrier selection page explain how we narrow the list.

How we quote a White Mountains home

• Start with the basics: address, the year it was built, size, construction (timber frame, log, stick-built) and the age of the roof.
• Describe the use pattern, such as full-time, ski weekends and holidays, or nights rented out.
• Tell us about heat, alarms, water shutoff, wood stoves and who checks the house and clears the roof.
• If a river or brook runs nearby, include the flood zone and any flood policy you already carry.
• We line up the home and flood options, then fit the umbrella, sleds, vehicles and valuables around them.

Base the dwelling limit on rebuild cost, using an appraisal or our replacement cost estimator, rather than the sale figure or the town’s assessment. Custom timber, stone and glass in a remote location usually cost more to replace than the market value suggests.
