How Can I Prevent Storm Damage During Rainy Season?
Last updated October 20, 2026
The short answer
Maintain Your Roof and Gutters
Inspect your roof before the rainy season begins. Look for missing, cracked, or curling shingles that could allow water to seep underneath. Check for damaged flashing around chimneys, vents, and skylights. A small defect can become a major leak during heavy wind-driven rain.
Clean your gutters and downspouts thoroughly. Clogged gutters cause water to overflow, potentially damaging your roof, siding, and foundation. Ensure downspouts extend at least five feet away from your home's base. This simple step keeps pooling water from seeping into your basement or crawlspace.
Seal Windows and Doors
Check the caulking and weatherstripping around all windows and exterior doors. Old, brittle, or missing sealant lets rainwater infiltrate walls and floors. Reapply a quality exterior-grade caulk to any gaps you find. This creates a watertight barrier against the elements.
Consider installing storm shutters or using pre-cut plywood for your windows if high winds are forecast. This protects against broken glass and significant water entry. Reinforce garage doors, as they can fail under pressure, allowing wind and rain to enter and cause structural issues.
Improve Yard Drainage
Grade your soil so it slopes away from your foundation. Over time, soil can settle and create depressions that channel water toward your home. Adding soil to create a gentle slope is a critical defense against basement flooding and foundation cracks.
Install French drains or dry creek beds in areas where water consistently pools. Keep storm drains on your property clear of leaves and mud. If you live in San Antonio, be aware that sudden, intense downpours can overwhelm poor drainage quickly, making these preparations vital.
- Clear debris from yard drains and culverts.
- Direct downspout runoff toward the street or a dry well.
- Use rain barrels to capture roof runoff.
- Plant native, water-tolerant vegetation in soggy areas.
- Avoid piling mulch too high against your home's siding.
- Check that your sump pump is operational if you have one.
Secure Outdoor Items and Trim Trees
Anchor or store lightweight outdoor furniture, grills, trash cans, and decor. These items can become dangerous projectiles in strong winds, breaking windows or damaging siding. Secure sheds, play sets, and gazebos according to the manufacturer's instructions to prevent them from tipping over.
Trim tree branches that hang over your roof or near power lines. Dead or weak limbs are likely to break and fall. Remove any trees that are rotted or unstable. Keeping trees healthy and properly pruned reduces the risk of them falling onto your house during a storm.
Prepare an Emergency Plan
Know the location of your main water shutoff valve and your electrical panel. If a pipe bursts or flooding begins, turning off the utilities can prevent further damage. Keep the necessary tools, like a wrench, nearby and ensure all family members know what to do.
Assemble a basic emergency kit with flashlights, batteries, a radio, and important documents in a waterproof container. Identify a safe room in your home, such as a basement or interior room without windows. Having a plan helps you act quickly and safely when severe weather strikes.

What should I do if water gets in during a storm?
If it is safe, try to contain the water with towels and move valuables to a dry area. Once the storm passes, contact local water damage pros. They have the equipment to extract water, dry the structure properly, and help prevent mold.
Does homeowners insurance cover storm damage?
Many policies cover sudden, accidental 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 agent to understand your specific coverage before storm season.
How can I tell if my roof is damaged after a storm?
Look for missing shingles, granule loss in gutters, or visible water stains on ceilings inside your home. For a thorough inspection, especially after hail, hire a qualified roofer. They can identify subtle damage you might miss, which could lead to leaks later.
