How to Prevent Storm Water Damage

Storms can bring heavy rain, wind, and flooding that cause significant damage to your home. Taking proactive steps to prepare and protect your home can prevent costly water damage and keep your family safe during severe weather.

Exterior Protection

Roof Maintenance

Critical preparation:

• Inspect your roof for missing, cracked, or damaged shingles
• Check flashing around chimneys, vents, and skylights for damage or gaps
• Look for signs of previous leaks in your attic
• Clear debris from roof valleys and around roof penetrations
• Trim tree branches that overhang or could fall on your roof
• Ensure roof vents and exhaust fans are properly sealed
• Check that gutters are properly attached and functioning

When to call a professional:

• If you notice significant damage or missing shingles
• If you see signs of active leaks
• If your roof is more than 20 years old and hasn't been inspected recently
• If you're not comfortable inspecting the roof yourself
• If you notice sagging or structural concerns

Gutter and Downspout System

Essential maintenance:

• Clean all gutters thoroughly (remove leaves, twigs, and debris)
• Check for loose, damaged, or sagging gutter sections
• Ensure gutters are properly sloped (1/4 inch per 10 feet toward downspouts)
• Test gutter flow with a garden hose
• Check that downspouts are clear and unobstructed
• Extend downspouts at least 5-10 feet away from your foundation
• Consider installing gutter guards to reduce maintenance
• Install downspout extensions if yours are too short
• Ensure downspouts direct water to appropriate drainage areas

Why this matters: Clogged or improperly functioning gutters can cause water to overflow and pool around your foundation, leading to basement flooding and foundation damage during storms.

Foundation and Drainage

Improve water management:

• Inspect your foundation for cracks (monitor existing ones, repair new ones)
• Ensure the ground slopes away from your foundation (at least 6 inches over 10 feet)
• Clear debris from foundation drains and window wells
• Check that window wells have covers and are properly drained
• Install French drains or surface drains if you have persistent water issues
• Ensure sump pump is working (if you have one)
• Check that drainage systems are clear and functioning

Grading improvements:

• Add soil around your foundation to create proper slope (use compacted soil, not loose fill)
• Consider installing a swale (shallow ditch) to direct water away from your home
• Ensure driveways and walkways slope away from the house
• Create berms or raised areas to divert water flow
• Install catch basins or dry wells for downspout water

Siding and Exterior Walls

Seal potential entry points:

• Check for cracks or gaps in siding, brick, or stucco
• Inspect and repair caulk around windows and doors
• Look for signs of water damage or rot
• Ensure exterior walls are properly sealed
• Check that vents and penetrations are properly sealed
• Repair any damage before storms arrive

Interior Protection

Basement and Crawl Space

Protect below-grade areas:

• Inspect basement walls and floors for cracks or signs of water intrusion
• Check for musty odors or signs of mold (indicates previous moisture issues)
• Ensure sump pump is working (test it by pouring water into the sump pit)
• Clear area around sump pump (ensure it can operate freely)
• Install a battery backup for your sump pump if you don't have one
• Check that basement windows are properly sealed
• Ensure window wells are clear and have covers
• Consider installing a water alarm to alert you to flooding

Waterproofing measures:

• Apply waterproofing sealant to interior basement walls if needed
• Install a dehumidifier to control moisture levels
• Ensure proper ventilation in crawl spaces
• Consider installing a French drain or interior drainage system if you have recurring issues
• Seal any cracks in basement walls or floors

Plumbing and Electrical

Safety preparations:

• Know where your main water shutoff valve is located
• Test that the shutoff valve works (turn it off and on)
• Check for leaks in plumbing fixtures and pipes
• Ensure electrical outlets in basements are GFCI protected
• Consider raising electrical panels and outlets if your basement floods frequently
• Keep important documents and valuables in waterproof containers or on upper floors
• Install water alarms near water heater, washing machine, and sump pump

Attic Inspection

Check for vulnerabilities:

• Inspect for signs of roof leaks (stains, water marks, mold)
• Ensure attic ventilation is adequate (prevents moisture buildup)
• Check insulation for signs of water damage
• Look for gaps or openings that could allow water entry
• Ensure attic access door is properly sealed
• Check that roof penetrations are properly sealed

Emergency Preparedness

Create an Emergency Kit

Essential supplies:

• Flashlights and extra batteries
• Battery-powered or hand-crank radio
• Non-perishable food and water (3-day supply)
• First aid kit
• Emergency contact numbers
• Waterproof containers for important documents
• Sandbags (if you're in a flood-prone area)
• Sump pump backup (battery-powered or water-powered)
• Water alarm or sensor
• Emergency tools (shovel, bucket, etc.)

Know Your Systems

Important information:

• Location of main water shutoff valve
• Location of electrical panel and how to reset breakers
• Location of gas shutoff valve (if applicable)
• How to operate your sump pump manually
• Emergency contact numbers (plumber, electrician, water damage restoration)
• Location of storm drains and drainage systems

Insurance and Documentation

Protect your assets:

• Review your homeowner's insurance policy (understand flood coverage)
• Consider flood insurance if you're in a flood-prone area (standard policies don't cover flooding)
• Document your home's condition with photos or video
• Keep important documents in waterproof containers or safe deposit box
• Create an inventory of valuable items (for insurance claims)
• Know your policy limits and deductibles

During a Storm

Monitoring

Stay vigilant:

• Monitor weather forecasts and warnings
• Check your sump pump regularly (if you have one)
• Inspect your basement and crawl space for signs of water
• Monitor gutters and downspouts (ensure they're flowing properly)
• Watch for water pooling around your foundation
• Check that water is flowing away from your home
• Listen for unusual sounds (may indicate water entering)

Immediate Actions

If water starts entering:

• Move valuables to higher ground immediately
• Turn off electricity in affected areas if safe to do so (never stand in water)
• Contact a plumber or water damage restoration company
• Document damage with photos for insurance
• Don't enter flooded basements if water is near electrical outlets or panels
• Use sandbags to divert water if possible
• Ensure sump pump is operating if you have one

Safety Precautions

Stay safe:

• Never drive through flooded areas
• Avoid walking through standing water (may be contaminated or hide hazards)
• Don't use electrical appliances in wet areas
• Keep children and pets away from floodwaters
• Evacuate if authorities recommend it
• Don't attempt to enter flooded basements with electrical hazards

After a Storm

Inspection and Assessment

Check for damage:

• Inspect your roof for leaks or damage
• Check gutters and downspouts for damage or blockages
• Examine foundation for new cracks or signs of water intrusion
• Inspect basement and crawl space for water damage
• Look for signs of mold or mildew (can develop within 24-48 hours)
• Check exterior walls and siding for damage
• Test all systems (electrical, plumbing, HVAC)

Cleanup and Repairs

Address issues promptly:

• Remove standing water as soon as possible
• Dry out affected areas (use fans and dehumidifiers)
• Clean and disinfect areas that were flooded
• Repair any damage to prevent future issues
• Replace damaged insulation or drywall
• Address mold issues immediately
• Document all damage for insurance

Prevent Future Issues

Learn from the experience:
