Real Estate Owners Commercial Property Insurance
Call Us: 603-766-3733
Owning commercial real estate in New Hampshire means contending with a set of risks that most generic insurance policies simply weren't designed for. Between ice storms that can collapse a roof overnight and century-old building codes that complicate reconstruction, the Granite State demands a more thoughtful approach to property coverage. Commercial property premiums statewide
increased by 15.1% from $118 million in 2023 to $135 million in 2024, reflecting both rising replacement costs and a growing awareness of regional exposures. If you own multi-family housing in Manchester, a retail strip in Nashua, or industrial space along the Merrimack River, the specifics of your policy matter far more than the price on the declarations page. This guide breaks down the specialized coverage, carrier dynamics, and claims realities that NH real estate owners need to understand before their next renewal.
New Hampshire's commercial real estate market sits in a unique position. The state benefits from no sales tax and no state income tax, which attracts businesses and keeps vacancy rates relatively low. But those advantages come with physical risks that are distinctly New England: harsh winters, aging building stock, and river systems that create flood exposure in places you might not expect. Understanding how these factors shape your insurance program is the first step toward building real protection.
Impact of Regional Weather Patterns on NH CRE Risk
The winters here aren't just cold; they're structurally punishing. A typical season brings 60 to 80 inches of snow in the southern tier and well over 100 inches in the White Mountains region. That snow accumulates on flat commercial roofs, and when a mid-winter thaw is followed by a hard freeze, ice dams form along parapets and drainage points. The result: interior water damage, sometimes catastrophic.
Wind events are another concern. Nor'easters can produce sustained winds above 60 mph, and microbursts during summer thunderstorms have caused significant damage to commercial properties in the Seacoast region. Carriers underwriting NH properties pay close attention to roof age, roof type, and snow removal protocols. If your building has a membrane roof older than 15 years, expect questions during the application process.
Key Differences Between Standard and Specialized NH Policies
A standard commercial property policy covers the basics: fire, wind, theft, and named perils. But standard forms often fall short for NH property owners in three critical areas: flood (always excluded), equipment breakdown (often excluded), and ordinance or law coverage (limited or absent).
| Coverage Feature | Standard Policy | Specialized NH Policy |
|---|---|---|
| Named Perils vs. Open Perils | Named perils only | Open perils (broader) |
| Flood/Surface Water | Excluded | Available via endorsement or separate policy |
| Ordinance or Law | $0 or minimal sublimit | Full replacement with code upgrade |
| Equipment Breakdown | Excluded | Included or available |
| Ice Dam / Snow Load | May be sublimited | Full coverage with loss control support |
| Business Income | 12-month limit typical | Extended to 18-24 months |
Specialized policies designed for NH real estate owners address these gaps head-on. An agency like Avery Insurance Agency, which has spent over 125 years working with New England property owners, will typically build a portfolio that layers these coverages based on the specific vulnerabilities of each asset.

Critical Coverage Components for Granite State Properties
Getting the right coverage isn't about buying the most expensive policy. It's about matching your exposures to the right endorsements and sublimits. Here are the three areas where NH property owners most commonly find themselves underinsured.
Ordinance or Law Coverage for Aging NH Infrastructure
A huge percentage of commercial buildings in New Hampshire were built before 1980. Many downtown properties in Concord, Keene, and Portsmouth date to the early 1900s. When one of these buildings suffers a major loss, rebuilding to current code can cost 30 to 50% more than the original structure's insured value.
Ordinance or law coverage pays for three things: the cost to demolish undamaged portions of a building that no longer meet code, the increased cost of construction to comply with current building codes, and the loss of value of the undamaged portion. Without this coverage, a partial loss can become a financial disaster. I've seen property owners face six-figure gaps between their insurance payout and actual reconstruction costs because they skipped this endorsement.
Flood and Surface Water Risks in NH River Valleys
The Merrimack, Connecticut, and Pemigewasset rivers all create flood exposure for commercial properties that may sit well outside FEMA-designated flood zones. The 2023 and 2024 storm seasons reminded many NH owners that surface water runoff, not just river overflow, can cause significant basement and ground-floor damage.
Standard commercial property policies exclude flood entirely. You'll need either a National Flood Insurance Program policy or a private flood policy, and the difference in coverage limits and pricing can be substantial. Private flood markets have expanded in New Hampshire, and for properties valued above $1.5 million, private options often provide better terms than NFIP.
Equipment Breakdown and Severe Winter Climate Protection
Boiler failures in January aren't hypothetical in New Hampshire; they're a regular occurrence. When a heating system fails in a multi-family building during a cold snap, the resulting pipe bursts and water damage can exceed the cost of the boiler itself by a factor of ten.
Equipment breakdown coverage (sometimes called boiler and machinery) covers the repair or replacement of mechanical and electrical equipment, plus the resulting property damage and lost rental income. For any NH property with a boiler, commercial HVAC system, or elevator, this coverage is essential, not optional.
Carrier Appetite and Market Trends in New England
The insurance market for NH commercial property is more competitive than you might assume. The overall combined ratio for commercial property in New Hampshire was 78% in 2023 and 86% in 2024, meaning carriers are making money here. That profitability attracts competition.
Preferred Asset Classes: Multi-Family, Industrial, and Retail
Carriers writing in New Hampshire tend to favor well-maintained multi-family properties, light industrial buildings, and neighborhood retail. These asset classes have predictable loss histories and stable occupancy. The top five insurance groups write about 36% of total commercial property premium, with the largest single carrier holding just 6.8% market share. That fragmentation is good news for buyers: it means no single carrier dominates, and there's real competition for desirable accounts.
Properties that carriers find less attractive include older wood-frame buildings with deferred maintenance, mixed-use properties with restaurant tenants (fire risk), and anything within a high-hazard flood zone without mitigation measures. If your property falls into one of these categories, working with a consultative agency that knows which markets have appetite for tougher risks makes a real difference.
Impact of Valuation and Replacement Costs in the Current Market
Construction costs in New Hampshire have risen sharply since 2021. Labor shortages and material costs mean that a building insured for $200 per square foot two years ago may now cost $260 or more to replace. Underinsurance is the single most common mistake I see among NH commercial property owners.
More than 30 new insurance companies entered the New Hampshire market in 2025, which has created more options for well-valued properties. But carriers are also scrutinizing valuations more carefully. If your stated replacement cost looks low relative to the building's age and construction type, expect the underwriter to push back or impose a coinsurance penalty.
Claims Considerations and Localized Risk Mitigation
Filing a claim is where your policy either proves its worth or reveals its gaps. NH property claims have distinct patterns that every owner should understand.
Managing Ice Dam and Snow Load Claims
Ice dam claims are among the most frequent and frustrating for NH property owners. The damage often starts small: a leak in a ceiling tile, a water stain on a wall. By the time the full extent is discovered, mold may have developed behind walls, and the claim has grown from a few thousand dollars to tens of thousands.
The key to managing these claims is documentation and speed. Photograph the exterior ice formation and interior damage immediately. Hire a snow removal contractor before accumulation exceeds your roof's load rating (typically 30 to 40 pounds per square foot for commercial flat roofs). Keep receipts for all mitigation efforts, as these costs are generally covered under your policy.
Best Practices for Property Maintenance and Loss Control
Carriers reward proactive maintenance with better pricing and fewer claim disputes. A solid loss control program for NH commercial property includes seasonal roof inspections (fall and spring at minimum), heat trace cable on vulnerable roof edges and gutters, annual boiler and HVAC servicing with documented records, and a written snow removal plan with a contracted vendor.
The New Hampshire Insurance Department reported
$633,196 in recoveries for consumers from property and casualty cases in 2025, a reminder that disputes do happen and that proper documentation protects you on both sides of a claim.
Strategic Insurance Procurement for NH Real Estate Owners
The NH market is considered more stable, competitive, and healthy compared to many other states, even during a period of rising premiums nationally. That stability creates opportunity for owners who approach their insurance strategically rather than reactively.
Start your renewal process 90 to 120 days before expiration. Update your property valuations annually using local construction cost data, not national averages. And work with an agency that understands NH-specific exposures. Avery Insurance Agency's consultative approach is built around uncovering the vulnerabilities that generic policies miss, giving property owners the confidence to focus on their investments rather than worrying about what happens when the next storm hits.
Frequently Asked Questions
Does my commercial property policy cover flood damage in New Hampshire? No. Flood is always excluded from standard commercial property policies. You need a separate flood policy through NFIP or a private flood insurer.
How often should I update my building's replacement cost valuation? Annually. Construction costs in NH have risen 20 to 30% in recent years, and an outdated valuation can trigger coinsurance penalties that reduce your claim payout.
Are ice dam claims covered under commercial property insurance? Yes, the resulting water damage is typically covered under an open-perils policy. The ice dam itself isn't "damage," but the interior water intrusion it causes is a covered loss.
What is ordinance or law coverage, and do I need it? It pays the extra cost to rebuild to current building codes after a loss. If your building is more than 30 years old, you almost certainly need it.
How many carriers write commercial property insurance in New Hampshire? The market is fragmented, with dozens of carriers competing. The top five groups hold only 36% of premium, which means plenty of options for well-maintained properties.

Got Questions? We’ve Got Answers.
Straight Answers From the Advisors Who Know This State Best
What does it mean that Avery is an independent insurance agency?
An independent agency like Avery is not tied to any single insurance company. We represent multiple top-rated carriers, which means we can shop the market on your behalf and recommend the coverage that truly fits your needs — not the one that benefits any single insurer.
This independence gives you access to more options and unbiased advice. Our advisors are compensated to serve your interests, not to push a specific product. That is a significant advantage over captive agents who can only offer one carrier’s policies.
How much does it cost to work with an Avery advisor?
There is no direct cost to you for working with an Avery advisor. Independent agents are compensated through commissions paid by the insurance carriers when a policy is placed. You receive expert guidance, market comparisons, and ongoing service at no extra charge.
In fact, many clients find that working with Avery saves them money. Our advisors know how to identify the right coverage levels so you are not paying for protection you do not need, and you are not left exposed where you do.
Does Avery help with claims?
Yes — and this is one of the most important things that sets Avery apart. When you have a claim, our in-house claims advisors go to work for you. We guide you through the process, communicate with the insurance company, and advocate for a fair and timely outcome.
Several of our team members hold professional claims designations, including AIC and AINS. We do not just help you file paperwork — we actively represent your interests to make sure you receive the full benefit your policy provides.
Where in New Hampshire does Avery provide coverage?
Avery serves clients throughout the state of New Hampshire from our offices in Wolfeboro and Portsmouth. Whether you live in the Lakes Region, the Seacoast, the White Mountains, or the Merrimack Valley, an Avery advisor is ready to help you find the right coverage.
Our advisors understand the specific risks that come with living and doing business in New Hampshire — from harsh winter weather to seasonal watercraft exposure. We apply that local knowledge to every coverage recommendation we make.
How does Avery handle high-value homes and assets?
Avery offers a dedicated Premier Client Services program for clients with homes valued over .5 million, significant investment portfolios, fine art collections, jewelry, yachts, and other complex assets. This program pairs you with a specialist who understands the unique risks of high-net-worth households.
Through carriers that specialize in high-value personal lines, we provide guaranteed replacement cost coverage, agreed value policies, and comprehensive risk management strategies. Your advisor will conduct a detailed review of your full asset portfolio to make sure nothing is overlooked or underinsured.
How often should I review my insurance coverage?
Avery recommends a full coverage review at least once a year. Major life events — buying a home, starting a business, adding a vehicle, getting married, or making significant home improvements — are all good triggers for an immediate review outside your annual cycle.
Insurance needs change over time, and policies that were right for you a few years ago may leave gaps today. Avery advisors proactively reach out to clients for annual reviews and keep up with changes in the insurance market that could affect your coverage or premium. Our goal is to make sure you are always protected and never paying for coverage that no longer fits.
