What Construction Projects Need to Know
A half-built home has no roof to speak of. A commercial frame in progress has open walls and exposed materials sitting on-site for weeks. When a storm rolls through, there is nothing between a construction project and serious financial damage. That is why wind, hail, and hurricane coverage within a builders risk policy matters so much, and why contractors and developers across the country are asking sharper questions about what their policy actually covers before they break ground.
Farmer Brown Insurance Services has been writing builders risk coverage across all 50 states since 1996. Contractors and developers can request same-day quotes at farmerbrown.com.
What Wind, Hail, and Hurricane Perils Mean in a Builders Risk Policy
A standard builders risk policy is a property insurance product. It covers structures under construction, renovation, or installation against physical loss or damage. Most policies are written on an open perils basis, meaning they cover everything unless specifically excluded.
Wind, hail, and hurricanes are named perils within that framework. In practical terms:
Wind damage
Wind damage covers physical loss caused by high-velocity wind, including straight-line winds, thunderstorm downbursts, and tornadoes. This includes blown-off framing, damaged roofing materials, fallen scaffolding, and debris impact.
Hail damage
Hail damage covers impact damage from hailstones. On a construction site, that often means dented metal roofing, broken skylights, cracked siding, or compromised membrane materials before they are even installed.
Hurricane coverage
Hurricane coverage refers to tropical cyclone-related loss, including wind damage and flying debris. Some policies also address storm surge, but that depends entirely on the policy language.
Wind and hurricane are sometimes written as two separate line items, each with a different deductible structure. Reading the declarations page carefully is not optional.
Construction Insurance for Advertising Injury Claims
A completed structure has insulation, finished walls, a sealed roof, and drainage. A building under construction often has none of those things. That gap creates a significantly different risk profile.
Open wall cavities can funnel wind forces through a structure and multiply pressure on the framing. Loose materials, lumber stacks, and temporary staging are potential projectiles. A tarp over an unfinished roof offers almost no real protection in a hurricane.
Most standard homeowner’s policies do not cover homes under construction at all. That makes builders risk insurance a necessity for anyone breaking ground or undertaking major renovations, not just a precaution.
Insurers factor storm exposure into their underwriting. Projects in coastal states, tornado-prone corridors, and hail belt regions often require more documentation, higher deductibles for wind-specific claims, or additional endorsements to maintain full coverage. Ninety-three percent of hurricane landfalls along the U.S. Gulf and East coasts occur between August and October, making that window particularly critical for active construction projects.
What Builders Risk Wind and Hail Coverage Costs
For new construction, builders risk insurance rates at Farmer Brown run approximately 30 cents per $100,000 of insured value. A $500,000 new construction project carries a premium around $1,500 for the policy term.
Renovation and rehab projects carry higher risk and a higher price. Those projects run approximately 65 cents per $100,000 of insured value, reflecting the exposure that comes with partially demolished structures and mixed-use materials.
Wind and hail exposure can push premiums upward depending on project location. A new construction project in Miami-Dade County is rated differently than the same project in Denver. Coastal surcharges, named storm exclusions, and wind deductible endorsements all affect the final cost and coverage structure.
Highest-Risk States and Regions for Wind and Hail Claims
Several regions carry significantly elevated wind and hail risk on construction projects:
Florida and the Gulf Coast
Florida and the Gulf Coast face the most concentrated hurricane exposure in the country. Florida projects often require wind mitigation documentation and may be subject to named storm deductibles on every policy.
Texas
Texas combines Gulf Coast hurricane risk in the south with a severe hail corridor running through Dallas, Fort Worth, San Antonio, and Austin. Hail events in North Texas have produced some of the largest insured losses in the construction market over the past decade.
The Carolinas
The Carolinas sit in the path of Atlantic hurricane tracks. Coastal construction in North and South Carolina is subject to both wind and named storm deductible provisions.
The Midwest hail belt
The Midwest hail belt, running roughly from Nebraska through Kansas, Oklahoma, and into Missouri, produces frequent large-hail events from spring through early fall. Projects in this corridor need specific attention to hail deductible structures.
What the Policy Covers Beyond the Structure Itself
Builders’ risk policies with wind and hail coverage generally extend beyond the building frame. Materials stored on-site are typically included. That means lumber, roofing materials, windows, and equipment waiting for installation are covered if a storm damages them before they go in.
Coverage limits and conditions for stored materials vary by policy. Some carriers cap coverage on materials at a percentage of the total insured value. Others require materials to be secured or enclosed to qualify. Reviewing those conditions before a storm season starts is worth the time.
What Is Typically Excluded and How Endorsements Fill the Gaps
Even on open perils builders risk policies, certain losses may be excluded or limited:
Flood from storm surge
Flood from storm surge is commonly excluded from standard builders risk policies, even when a hurricane causes it. A separate flood endorsement or a National Flood Insurance Program policy may be required.
Soft costs
Soft costs such as project delays, additional interest charges, or architect fees caused by a storm event may require a soft cost endorsement to be covered.
Earth movement
Earth movement caused by storm-related soil saturation is often excluded.
Materials stored off-site
Materials stored off-site may have limited coverage or require a separate inland marine floater.
Endorsements exist to address most of these gaps. Identifying them before a loss occurs is what separates a well-structured policy from one that surprises the contractor at the worst possible moment.
