Hurricane Isaias building damage
Wind and water leave different marks on a building after Hurricane Isaias. Wind damage starts high and at the edges: roof coverings, soffits, fascia, gable ends, windows and doors. Surge and flood damage starts low, with a water line, silt and debris on the lowest floors. A building can show both, and each leaves its own marks.

This guide explains how wind and water leave different marks, and how that distinction is made when a loss is disputed.

What I offer in Florida is damage documentation for commercial property owners and expert opinions for attorneys. Homeowners can use these guides or call me to talk it through. I do not hold a Florida or Alabama contractor license and offer no repair work; repairs go to a Florida-licensed contractor you choose, and you can verify any Florida license at myfloridalicense.com.
Florida law states:
The consumer is responsible for payment of any insurance deductible. It is insurance fraud punishable as a felony of the third degree for a contractor to knowingly or willfully, and with intent to injure, defraud, or deceive, pay, waive, or rebate all or part of an insurance deductible applicable to payment to the contractor for repairs to a property covered by a property insurance policy. It is insurance fraud punishable as a felony of the third degree to intentionally file an insurance claim containing any false, incomplete, or misleading information.

- Before landfall, Moody’s estimated nearly 32,000 commercial properties across coastal Alabama and the Florida Panhandle had a better than even chance of 50 mph or stronger winds, worth a combined $71.8 billion, with the largest concentrations in Mobile and Pensacola. That is exposure, not damage. Source: PropertyCasualty360
Reading high and reading low
Wind damage tends to start high and at the edges: roof coverings, ridges, soffits, fascia, gable ends, windows and doors. Surge and flood damage starts low: it leaves a water line, silt and debris on walls and fixtures, and it affects the lowest floors first. A building can have both, and each leaves its own marks.
In a dispute, that split is a technical question about the building, decided on evidence. It can call for an expert. See expert witness.
The walk around your own building
Roof
From the ground: missing coverings, debris, bent edges. See roof damage.
Walls
Siding, trim, soffit and fascia. See siding damage.
Openings
Window and door frames, glazing, garage doors and seals.
Interior
Ceilings, floors and walls, only if the building is safe to enter.
Water line
If water stood in the building, photograph the mark on the wall with a tape measure or a person beside it for scale.

Questions, answered plainly
How do wind damage and flood damage differ after Hurricane Isaias?
Wind and water leave different marks on a building after Hurricane Isaias. Wind damage starts high and at the edges: roof coverings, soffits, fascia, gable ends, windows and doors. Surge and flood damage starts low, with a water line, silt and debris on the lowest floors. A building can show both, and each leaves its own marks.
How can wind damage be told from flood damage?
By where and how the damage appears: height, pattern, water lines, silt and debris, and the condition of the components above and below.
Can you tell me if this is covered?
No. Coverage questions go to your insurer, the Florida Department of Financial Services consumer helpline, or an attorney.
Is it safe to go inside?
Follow local officials. Do not enter a building with structural damage, standing water near electrical service, or a sagging ceiling.
What does storm surge damage look like inside a building?
Surge and flood damage starts low. It leaves a water line, silt and debris on walls and fixtures, and it affects the lowest floors first. If water stood in the building, photograph the mark on the wall with a tape measure or a person beside it for scale.
Did Hurricane Isaias bring storm surge as well as wind?
Yes, per reporting. The Guardian described wind, rain and storm surge for the Panhandle. Source: The Guardian CNN reported that storm surge breached Destin and that winds ripped the roof off a hotel near Fort Walton Beach. Source: CNN
What should I check when I walk around my building?
Work in order: the roof from the ground, then walls, siding, trim, soffit and fascia, then window and door frames and seals. Check interior ceilings, floors and walls only if the building is safe to enter, and photograph any water line.
Safety first, always
Do not climb a damaged roof. Stay clear of downed power lines, standing water and unstable structures, and follow guidance from local officials and FEMA.
For commercial owners in Florida I document damage, and in disputes I give technical opinions. Coverage questions go to your insurer, the Florida Department of Financial Services consumer helpline, or an attorney. I am not an attorney.
