How to Prepare Your Siding for Hurricane Season in New Orleans

Written by Turnkey Siding

How do you prepare siding for hurricane season in New Orleans?

Quick Answer: To prepare siding for hurricane season, inspect every wall for loose or cracked panels and refasten them, seal and re-caulk gaps around windows, doors, and penetrations, clear gutters and downspouts so water drains away from the house, trim branches that could strike the walls, secure loose yard items that can become projectiles, and photograph the siding’s current condition for your records. The goal is simple: close every gap where wind-driven rain can get behind the panels before a storm arrives.

Why hurricane prep matters for New Orleans siding

New Orleans homes take a beating that has little to do with salt air. The real drivers here are heat, heavy humidity, and wind-driven rain. When a tropical system pushes water sideways at 30 or 40 degrees, it finds any seam, nail pop, or dried-out caulk line you’ve been ignoring. Storms like Hurricane Katrina in 2005 and Hurricane Ida in 2021 showed how fast a small weakness in the building envelope turns into water inside the wall.

Good news: most of this prep is work you can do yourself in a weekend or two. The point isn’t to rebuild anything. It’s to ready your siding for a storm by tightening up what’s already on the house. If your inspection turns up real damage, that’s a repair job, and you’ll find more on that in our guide to siding repair in New Orleans.

Your pre-hurricane siding checklist

Run through these steps in order. Early in the season, do the full inspection. Then, when a named storm enters the Gulf, do a fast second pass on the quick items.

1. Inspect every wall for loose or cracked panels

Walk the full perimeter on a dry day. Look for panels that rattle, bow out, or have pulled away at the bottom edge. Press gently along the courses; anything that flexes or clicks is loose. Check for cracks, splits in wood siding, and chips in fiber cement or stucco. Pay extra attention to corners, the bottom row, and any spot near a downspout, since those areas catch the most water.

• Loose panels that lift or flap in wind let rain blow straight behind the siding.
• Cracks and splits widen under pressure and let moisture into the wall cavity.
• Missing or backed-out nails leave a panel free to peel off in a gust.

2. Secure and refasten anything loose

Re-nail or re-clip loose courses according to how your siding type fastens. Vinyl needs room to expand, so don’t drive nails tight; let the panel float. Wood, fiber cement, and metal each fasten differently, so match the method to the material. If a panel is cracked through or a section is rotted soft, that’s beyond a quick refasten and needs a proper repair before the storm, not a patch of tape.

3. Seal gaps and re-caulk penetrations

This is where most storm leaks start. Inspect the caulk lines around every window, door, hose bib, dryer vent, electrical box, and pipe that passes through the wall. Old caulk shrinks, cracks, and pulls away in the New Orleans heat. Scrape out the failed beads and lay down fresh exterior-grade sealant. Don’t seal the bottom weep edges of vinyl or the drainage points the system needs; those let trapped water escape on purpose.

• Windows and doors: seal the trim-to-siding joint, not the weep holes.
• Penetrations: vents, spigots, cable, and conduit all need a tight collar of sealant.
• Trim and corners: re-caulk where boards meet so wind-driven rain can’t track in.

4. Clear gutters, downspouts, and drainage

Clogged gutters overflow and dump water down the wall, soaking the siding from the top edge in. Clean out leaves and grit, flush the runs, and confirm downspouts carry water several feet away from the foundation. On our alluvial delta soil, water needs to move away from the house fast. Check that the grade slopes away from the walls and that splash blocks are in place.

5. Trim overhanging branches

Limbs that hang over or brush the house become battering rams in hurricane wind. Cut back branches that touch or reach over the roofline and walls. Even small twigs scrape paint and finish off in a sustained blow. This single step prevents some of the worst siding gouges we see after a storm.

6. Secure loose items that can become projectiles

When a named storm is forecast, walk the yard. Patio furniture, grills, planters, trash cans, garden tools, and kids’ toys all turn into missiles at hurricane wind speed, and they hit siding hard. Bring them inside, into the garage, or strap them down. A flying chair does far more damage to a wall than the rain does.

7. Photo-document the siding’s condition

Before the storm, take clear, dated photos of all four sides of the house, plus close-ups of any existing wear. Store them in the cloud or email them to yourself so they survive a power loss. If wind or debris damages the siding, these before photos prove the condition you started in. They make a real difference if you ever need to file a siding insurance claim after a Louisiana storm.

A note on materials and codes

This checklist is about protecting the siding you already have. If your home is older, took damage in a past storm, or you’re planning to replace siding anyway, the bigger question is what to install next. We cover that separately in our breakdown of storm-resistant and hurricane-proof siding materials for Louisiana, and the local rules in our guide to wind-rated siding and Jefferson Parish codes. Turnkey Siding installs all 8 siding types, from vinyl and fiber cement to metal, brick, and stucco, and our own crews handle every job; we never subcontract the work out.

Frequently Asked Questions

When should I start preparing my siding for hurricane season?

Start before June, when Atlantic hurricane season opens. An early inspection gives you time to schedule any real repairs while the weather is calm, instead of scrambling when a storm is already in the Gulf. Then keep a short checklist ready for fast prep whenever a named system threatens the New Orleans metro.

Can I refasten loose siding myself, or should I call someone?

Tightening a few loose clips or nails on the lower courses is reasonable for a handy homeowner who knows their siding type. But cracked panels, soft or rotted spots, high sections, and anything structural call for trained hands. If you’re unsure whether something is cosmetic or a real weak point, a free inspection settles it fast.

Does salt air damage New Orleans siding?

Salt air gets blamed a lot, but it’s not the main culprit here. The Gulf sits 40 to 50 miles south, and Lake Pontchartrain is brackish, not ocean salt water. The forces that actually wear siding in this area are heat, heavy humidity, and wind-driven rain. That’s why sealing gaps and managing drainage matter so much for storm prep.

What should I check first after a storm passes?

Once it’s safe, compare the house to your before photos. Look for cracked, loose, or missing panels, water staining along seams, and debris strikes. Note anything new and photograph it right away. Then have any suspected damage inspected so small problems get fixed before the next system, instead of after they’ve let water into the wall.
