Hurricane Season Prep: How to Protect Your Long Island Home

Long Island sits right in the path of the Atlantic hurricane season, and every year homeowners are reminded that a storm doesn't have to make landfall as a major hurricane to do serious damage. Tropical storms, their remnants, and even strong coastal Nor'easters regularly bring the wind, rain, and flooding that lead to roof damage, basement flooding, and downed trees across Nassau and Suffolk. The good news: most storm damage is far easier and cheaper to prevent than to repair. Here's how to get your home ready before the next storm is on the radar.

Know Your Risk on Long Island

The Atlantic hurricane season runs from June 1 through November 30, with activity usually peaking between mid-August and late October. Long Island's biggest vulnerabilities are wind (which lifts shingles and brings down aging trees and limbs), heavy rain (which overwhelms drainage and floods basements), and coastal storm surge in low-lying and waterfront areas. Knowing whether you're in or near a flood zone, and how water moves around your property, tells you where to focus.

Before the Storm: Your Home Prep Checklist

Roof & Exterior

Your roof is your first line of defense, and it takes the brunt of hurricane-force wind. Well before a storm:

• Have loose, lifted, or missing shingles repaired — wind gets under damaged shingles and peels them back.
• Check that flashing around chimneys, vents, and skylights is sealed and secure.
• Clear gutters and downspouts so heavy rain can actually drain instead of backing up under the roof edge.
• Secure or store loose outdoor items — furniture, grills, trash cans, and decorations become projectiles in high wind.

If your roof is older or you're unsure of its condition, a pre-season inspection is worth it. Our guide on roof replacement cost on Long Island covers what to look for and what a legitimate roofing estimate should include.

Trees & Landscaping

Falling trees and limbs are one of the leading causes of hurricane damage and power outages on Long Island. Trim back dead or overhanging branches, especially any near the house, driveway, or power lines, and remove clearly dying trees before the wind does it for you.

Windows & Doors

Wind-driven debris breaks windows, and once wind gets inside a home it can lift the roof from within. Install storm shutters or keep pre-cut plywood on hand for large windows and glass doors, make sure doors seal tightly, and consider bracing a lightweight garage door, which is often the most vulnerable large opening on the house.

Drainage & Basement

Basement flooding is the single most common storm claim we see, and much of it is preventable:

• Test your sump pump before the season and add a battery backup — pumps fail exactly when the power goes out during a storm.
• Clear yard drains, window wells, and catch basins so water has somewhere to go.
• Extend downspouts so roof runoff discharges well away from the foundation.
• Seal foundation and basement wall cracks where water works its way in.
• Move valuables, electronics, and important items off the basement floor.

Emergency Kit & Documents

Put together a kit with several days of water and non-perishable food, flashlights, batteries, a portable charger, a first-aid kit, and any essential medications. Keep important documents — insurance policies, IDs, property records — in a waterproof container or backed up digitally.

Check Your Insurance Before the Storm

The worst time to learn what your policy actually covers is after the water is already in your basement. Review your coverage now, while you still have options.

• Wind vs. flood are different things. A standard homeowners policy usually covers wind damage, but it does not cover flood damage. Flooding requires a separate flood insurance policy.
• Flood policies have a waiting period. New flood insurance typically takes 30 days to take effect, so it can't be bought once a storm is approaching. If you're in or near a flood-prone area, handle this early.
• Know your deductible. Many coastal New York policies carry a separate hurricane or windstorm deductible — often a percentage of your home's value rather than a flat dollar amount — that applies when a storm is officially named.
• Document your home now. Photograph or video every room and the exterior while everything is intact. That "before" record makes any future claim dramatically easier.

When a storm does hit, thorough documentation is what protects your claim. Our step-by-step guide on how to document storm damage for an insurance claim walks through exactly what to capture.

During the Storm

Once the storm arrives, stay inside and away from windows and glass doors. Keep clear of any candles near flammable items, and never run a generator indoors or in an attached garage — carbon monoxide is a serious risk. If flooding begins to threaten, move to a higher floor, and if you lose power, leave one light switched on so you'll know when it returns.

After the Storm

When conditions clear, safety comes first: stay away from downed power lines, standing water (which can be electrified or contaminated), and any structural damage. Then move quickly on these three steps:

1. Document the damage — photos and video of everything, before you move or clean anything.
2. Prevent further damage — tarp roof openings, board broken windows, and start removing standing water where it's safe to do so. Insurers expect you to mitigate.
3. Call a restoration contractor — the faster water is extracted and drying begins, the less likely you'll face mold on top of the storm damage.

Speed matters most with water. If your basement or home took on water, our guide on how long water damage restoration takes explains the drying and rebuild timeline, and our water damage restoration crews respond 24/7.

Hurricane Prep: Frequently Asked Questions

When is hurricane season on Long Island?

The Atlantic hurricane season runs June 1 through November 30, with the highest activity typically from mid-August through October. On Long Island, tropical storms and their remnants are the most common threat, but direct hurricane impacts do occur, so it's best to prepare early in the season rather than when a storm is already named.

Does homeowners insurance cover hurricane damage?

Wind damage from a hurricane is usually covered by a standard homeowners policy, though many coastal New York policies apply a separate, percentage-based hurricane or windstorm deductible for named storms. Flood damage is not covered by a standard homeowners policy and requires a separate flood insurance policy. Always confirm the specifics with your own insurer.

Do I need flood insurance on Long Island?

If your home is in a designated flood zone, your mortgage lender likely requires it — but flooding can happen outside mapped flood zones too. Standard homeowners insurance doesn't cover flood damage, and new flood policies usually have a 30-day waiting period before they take effect, so it can't be purchased at the last minute before a storm.

What should I do first after storm damage to my home?

Make sure everyone is safe and avoid downed power lines and standing water. Then document all damage with photos and video before you clean up, take reasonable steps to prevent further damage such as tarping or board-up, and contact a licensed restoration contractor.
