The nor’easter wind versus flood problem
The nor’easter wind versus flood question is the heart of most coastal storm claims in Maine. A big nor’easter brings three forces at once: sustained wind, wind-driven rain and coastal surge. The January 10 and 13, 2024 storms showed this clearly, with a record tide at the Portland gauge, flooded waterfronts from Camp Ellis to Rockland and wind damage well inland.
Homeowners policies generally cover wind and exclude flood. When both hit the same building, the carrier has to decide which damage came from which source, and that decision drives the check.
What the flood exclusion usually says
Standard homeowners policies exclude flood, surface water, waves, tidal water and storm surge, whether or not driven by wind. Many include anti-concurrent causation language that tries to exclude damage when an excluded cause like flood combines with a covered cause like wind. How courts read that language varies, and it is a legal question for a Maine attorney.
Flood coverage comes from a separate National Flood Insurance Program policy or a private flood policy. If you have one, you may have two claims, two adjusters and two sets of rules for the same storm.
What wind damage typically looks like
Wind damage tends to show up high on the building and in patterns tied to wind direction.
- Missing or creased shingles, lifted ridge caps and torn underlayment
- Siding and trim pulled off on the windward side
- Broken windows and doors from debris
- Fallen trees and limbs on roofs, decks and outbuildings
- Interior water stains from rain entering through wind-created openings
Wind-driven rain
Many policies only cover rain damage inside the house if wind or hail first created an opening in the roof or walls. Rain pushed through an intact window frame may be treated differently. That distinction matters a lot after a long nor’easter with hours of sideways rain.
Separating wind from flood on paper
Clear evidence is the best tool for keeping wind damage from being folded into an excluded flood loss.
- Photograph the high-water line inside and outside, with a tape measure for scale.
- Photograph roof, siding and window damage above that line separately.
- Note the time water rose and the time wind damage happened, if you saw either.
- Keep weather reports, tide gauge data and local news coverage of the storm.
- Ask contractors to separate wind items from flood items in their estimates.
If you carry flood coverage, keep separate folders, photos and estimates for each policy. Overlap is where payments get delayed, and a clean split helps both adjusters do their jobs.
Where wind estimates fall short after a nor’easter
Even when the carrier accepts wind damage, the estimate often understates it. Common gaps include roof sections priced as patches when the shingles cannot be matched, siding on one elevation priced without matching the rest, and interior water damage assigned to flood when it came through the roof.
After a big storm, Maine contractor availability also matters. Roofers along the coast can be booked for months, and prices climb with demand. An estimate written with pre-storm pricing may not reflect what it costs to get the work done that season.
Illustrative example: an oceanfront cottage in York takes on two feet of surge in the basement and loses a large section of roof shingles and a band of cedar siding. The homeowners carrier estimates the wind damage at $11,000, attributing interior ceiling stains to flood. The owner’s contractor estimates $27,500, separating the roof leak damage from the basement flooding and adding matching for the siding. The numbers are invented for illustration only.
When the dispute is over amount, appraisal can help
Appraisal works when the carrier accepts that wind caused some damage and the disagreement is over how much. The panel can sort line items and decide what the wind repairs cost. Whether the flood exclusion or anti-concurrent causation language bars part of the loss is a coverage question, and some panels and courts treat causation disputes differently, so get a Maine attorney’s view on that piece.
