Knowing what to do after a hurricane hits your house is one of the most important things a Jacksonville homeowner can learn, and yet most guides you find online skip the part that matters most for your home. They focus on paperwork and safety, both of which matter, but they leave out what your roof, siding, and driveway are doing in the hours after the storm passes. That is where the real damage often begins.
At Hydro Wash 360, we have walked through countless Jacksonville yards in the days after a storm. So we wrote this guide from a neighbor’s perspective, not a government pamphlet’s. Here is what to do, in the order that actually protects your home.
What Should I Do First After a Hurricane Hits My House?
The first thing to do after a hurricane hits your house is make sure every person you love is safe before you inspect a single square foot of your property. Downed power lines, broken glass, and unsteady branches can turn a driveway into a hazard zone within seconds. If you evacuated, wait for local officials to give the all-clear before you drive back. If you sheltered in place, stay inside until you know the winds have fully calmed.
Once you step outside, look up before you look around. Watch for hanging tree limbs, damaged eaves, and any wires you do not recognize. If you smell gas or see sparking, walk away and call your utility company. Your home can wait. Your family cannot.
How Do I Document Hurricane Damage?
Document hurricane damage by taking as many photos as you possibly can before you move a single piece of furniture or drag one branch off your driveway. Your camera phone is the most important tool you have in the first hour after the storm passes.
Walk the whole property and capture:
- Every angle of your roof from the ground
- Any water lines or debris on your siding
- Standing water in your yard or garage
- Damaged fencing, screens, or pool enclosures
- Fallen branches touching or leaning on your home
- Any interior damage, even if it looks small
Insurance adjusters will need this record. So will you, later on, when the memory of what things looked like has already faded. Take more photos than you think you need, and back them up to the cloud before anything else.
When Should I Call My Insurance Company?
Call your insurance company as soon as reasonably possible after the storm passes, because most policies require prompt notice after a loss. Have your policy number ready and describe the damage in plain terms. If you spend money on emergency supplies, tarps, or a hotel stay, keep every receipt. Those often get reimbursed as part of the claim.
Do not make permanent repairs yet. Cover exposed areas with a tarp if you can safely do so, but leave the real work until the adjuster has seen the damage in person.
What to Do After a Hurricane Hits Your House on the Outside
Here is the part almost every online guide forgets. The outside of your home is where the fastest, most preventable damage happens after a storm, and Jacksonville’s climate makes it worse than nearly anywhere else in the country. Once the insurance basics are handled, turn your attention to the exterior. You have about 72 hours before the real problems set in.
The 72-Hour Mold and Algae Window Nobody Talks About
Mold and algae can begin growing on wet exterior surfaces within 24 to 48 hours of the storm passing, according to the Centers for Disease Control and Prevention. In Jacksonville’s heat and humidity, that clock runs even faster. Your siding, soffits, fences, and painted surfaces all get soaked during a hurricane, and once the sun comes back out, the warm damp surface becomes a perfect place for mold to grow.
A professional soft wash house cleaning within that first week removes the moisture, kills the mold at the root, and stops the bloom before it spreads into your paint and behind your siding. Waiting until you see green streaks means you have already lost weeks of work to a problem that could have been prevented in one visit.
Storm Debris and Algae on Your Roof
Your roof takes the worst beating of any surface on your home during a hurricane. Wind drives leaves, twigs, and dirt into the crevices between shingles, and rain forces moisture into places it should never sit. Left alone, that organic debris feeds algae growth, holds moisture against your shingles, and shortens the life of your roof by years.
Our team never uses high pressure on a roof. We use a soft wash method that follows the guidelines from the Asphalt Roofing Manufacturers Association, which keeps your shingle warranty intact. If your roof took visible damage from the storm, get a professional inspection first. If it looks clean but you know debris got driven into it, a professional roof cleaning is what protects the rest of its life.
Salt Residue, Gutters, Driveways, and Pavers
If your Jacksonville home sits anywhere near the coast, storm surge and wind carry salt spray far inland. Salt residue does not just look bad. It eats into paint, corrodes metal, and etches windows if it is left in place. A gentle rinse with fresh water within a few days of the storm is the difference between a home that ages gracefully and one that shows its salt scars for years.
Your gutters need attention too. They are almost certainly full of leaves and organic matter, and that mix holds water against your fascia and starts growing mold within days. Your driveway and pavers take on the same problem, especially where storm runoff pushes leaves and mulch into cracks and joints. Those stains set in fast if they are not cleaned within a week.
Why Jacksonville Homes Get Hit Harder
Jacksonville sits in a spot that gets hurt by hurricanes in ways other Florida cities do not. Our humidity averages over 70 percent even outside of storms. Our oak canopies dump thousands of pounds of debris on roofs. And our coastal proximity means salt makes its way into every neighborhood, not just the beaches. Our guide on how hurricane season affects your home’s exterior walks through the local science if you want to go deeper.
If you are reading this before the next storm, our pre-hurricane exterior checklist is the companion piece to this one. Together they cover the full season, from prep through recovery.
How Do I Stop Mold and Algae From Coming Back?
Stop mold and algae from coming back by removing them properly the first time, then adding a protective layer that slows their return. Our HydroGuard Exterior Protection treatment goes on right after the house wash and doubles the time before mold and algae grow back. In Jacksonville’s climate, that is the difference between washing your home once a year versus twice.
Think of it like sunscreen for your siding. It does not stop the sun, but it slows the damage down enough to matter.
What About Business Owners and HOAs?
Business owners and property managers face the same 72-hour window, only across more buildings and with more people watching. Storm-damaged storefronts, dirty breezeways, and streaked HOA entrances lose curb appeal and can pull down foot traffic before you even notice the damage. Our team works with property managers across Jacksonville to schedule fast post-storm cleanups that keep communities looking cared for, even when everyone is exhausted.
