The short answer

Maintain Your Roof and Gutters

A sound roof is your first defense against storm water. You should inspect shingles for cracks, curling, or missing pieces each season. Replace damaged sections promptly to prevent leaks. Clean gutters and downspouts ensure rainwater flows away from your foundation. Blocked gutters can cause overflow, leading to siding damage or basement flooding during heavy rain.

Check the flashing around chimneys, vents, and skylights for gaps or corrosion. Use roofing cement to seal minor issues. Consider having a professional roofer inspect your roof every few years if you are not comfortable on a ladder. They can spot hidden problems like soft spots or worn underlayment that you might miss.

Secure Windows and Doors

Strong winds can turn loose windows and doors into entry points for rain and debris. Check that all window and door frames are properly caulked and sealed. Install storm shutters or pre-cut plywood covers to protect glass during severe weather. In humid climates, wood frames can swell and shrink with seasonal changes, which may affect seals over time.

Examine weatherstripping around doors for wear and tear, replacing it if it's brittle or compressed. Ensure deadbolts and locking mechanisms are secure, as they help keep doors tightly closed. Reinforcing garage doors is also important, as they are often a weak point. A garage door reinforcement kit can prevent it from buckling under pressure.

  • Install impact-resistant windows or storm shutters.
  • Apply fresh exterior-grade caulk around all window and door frames.
  • Use security film on windows to hold shattered glass.
  • Check and replace worn weatherstripping on doors.
  • Install a garage door bracing kit for wind resistance.
  • Ensure all entry doors have at least three hinges and a deadbolt.

Manage Your Landscape and Drainage

Your yard's layout can direct water toward or away from your home. Grade the soil so it slopes away from your foundation at a minimum of six inches over ten feet. This prevents pooling and seepage into basements or crawl spaces. Extend downspouts at least five feet away from the house, using splash blocks or buried drain pipes to carry water further.

Trim tree branches that hang over your roof or near power lines. Remove dead or weak trees entirely, as they can topple in high winds. Secure or store lightweight outdoor furniture, grills, and decorations before a storm. These items can become projectiles that damage siding, windows, or neighboring properties.

Inspect Your Home's Exterior

Walk around your home's perimeter to look for cracks in the siding, brick, or stucco. Seal any gaps with appropriate exterior-grade sealant to keep wind-driven rain out. Pay special attention to where different materials meet, like where wood siding meets a brick chimney. These junctions are common leak sources. Also, check that all exterior vents have covers to prevent water intrusion.

Examine your foundation for cracks, no matter how small. Use hydraulic cement or a masonry sealer to fill them. Ensure window wells have covers to keep rainwater out. If you have a sump pump, test it regularly by pouring water into the pit. A working sump pump is critical for preventing basement flooding during torrential downpours.

  • Seal cracks in siding, brick, and foundation walls.
  • Install covers on all exterior vents (dryer, bathroom, kitchen).
  • Place covers on basement window wells.
  • Test your sump pump every few months.
  • Check that all exterior light fixtures are sealed and secure.
  • Inspect and repair any loose or damaged siding panels.

Prepare Your Home Systems

Your electrical and plumbing systems need protection too. Install ground fault circuit interrupter (GFCI) outlets in areas prone to moisture, like basements and exteriors. This helps prevent shocks if water gets inside. Know the location of your main water shutoff valve and ensure it turns easily. If a pipe bursts during a storm, quickly shutting off the water limits damage.

Consider installing a backwater valve in your main sewer line to prevent sewage backup during flooding. An electrician can elevate outlets in flood-prone areas of your home. If you have a generator for power outages, ensure it is installed with a proper transfer switch. This prevents back-feeding into power lines, which is a safety hazard.

Frequently asked questions

How often should I clean my gutters?

You should clean gutters at least twice a year, typically in late spring and early fall. If you have many overhanging trees, check them more often. Clogged gutters cause water to overflow, damaging your roof, siding, and foundation.

What should I do if I find roof damage?

If you spot missing shingles or leaks, cover the area temporarily with a tarp to prevent water entry. Then, contact a professional roofer for a permanent repair. Delaying fixes can lead to more extensive water damage inside your home.

Does home insurance cover storm damage?

Most standard policies cover sudden damage from wind or hail, but flooding often requires separate flood insurance. Policies vary, and your insurer decides what is covered. Review your policy and speak with your insurance agent to understand your specific coverage.
