The short answer

Roof and Flashing

Your roof takes the first hit from wind, hail, and rain. Loose or missing shingles, cracked flashing, and worn sealant around vents or chimneys allow water to seep into the attic and walls. Even a small leak can lead to rot and mold if left untreated.

After a storm, check your roof from the ground for visible damage, such as lifted shingles or exposed underlayment. If you see problems, contact local water damage pros for a professional inspection. They can identify hidden damage and help you plan repairs.

Windows and Doors

Windows and doors are common entry points for wind-driven rain. Cracked seals, worn weatherstripping, or improperly installed frames can let water run down interior walls. High winds can also break glass, allowing rain to pour in.

Inspect the caulking around window and door frames before storm season. If you notice gaps or damage, reseal them. After a storm, check for water stains on walls or ceilings near these openings. If water has entered, you may need professional drying and repair.

  • Check seals and weatherstripping
  • Look for cracked or missing caulk
  • Ensure windows close and latch tightly
  • Clear debris from door tracks
  • Inspect basement window wells for water

Foundation and Basement

Basements and crawl spaces are prone to flooding when heavy rain saturates the ground. Cracks in the foundation, poor drainage, or a failing sump pump can allow water to seep through walls and floors. This can damage belongings and create a damp environment.

Make sure gutters and downspouts direct water away from your home's foundation. If your basement has ever leaked, consider waterproofing measures. After a storm, check for standing water, damp spots, or musty odors. If water is present, act quickly to remove it and dry the area.

Siding and Exterior Walls

Siding, stucco, and brick veneer protect your home's structure from the elements. Storm damage can crack, chip, or loosen these materials, allowing moisture to penetrate the wall cavity. Over time, this can lead to wood rot and mold growth.

Inspect your exterior walls for cracks, gaps, or peeling paint. Pay special attention to areas where different materials meet, such as where siding meets a chimney or porch. If you find damage, repair it promptly. For extensive water intrusion, professional drying may be necessary.

Attic and Vents

Your attic is a hidden area where storm damage can go unnoticed. Wind-driven rain can enter through ridge vents, roof fans, or plumbing vents. If these openings lack proper flashing or seals, water can drip into insulation and ceiling drywall.

After a storm, look for wet insulation, dark stains on rafters, or dripping water in the attic. If you find moisture, have it addressed quickly to prevent mold. A water damage inspection can help you identify all entry points and plan effective repairs.

  • Check attic for wet insulation
  • Inspect vent boots and seals
  • Look for light coming through roof boards
  • Feel for damp spots on rafters
  • Monitor for musty odors

Frequently asked questions

What should I do right after a storm hits my home?

First, check for any immediate safety hazards like downed power lines or gas leaks. If you see damage, take photos for your records. If water is entering, try to stop it with buckets or tarps. Then contact local water damage pros to assess the situation.

Can I fix storm damage myself?

Small issues like a cracked window seal or a few missing shingles may be DIY projects. However, if water has soaked into walls, insulation, or drywall, you may need professional help to dry the structure and prevent mold. Always prioritize safety and call a pro for large or complex jobs.

How can I prevent storm damage to my home?

Regular maintenance is key. Keep gutters clean, trim tree branches near your roof, and inspect seals around windows and doors. If you live in Columbus, consider reinforcing your roof and foundation. After any storm, do a quick check of vulnerable areas.
