The short answer

Roof Damage

High winds put enormous upward force on roofs, often lifting shingles, tiles, or metal panels. Once the outer layer tears away, rain soaks the sheathing and rafters below. You might notice water stains on ceilings or daylight showing through the roof deck.

Missing shingles or a torn underlayment can let water spread far from the original leak. The longer the water sits, the deeper it travels into the wood. If you see sagging or a dip in the roofline, do not walk on it. Wait for a structural check.

  • Lifted or missing shingles
  • Torn underlayment or flashing
  • Sagging roof deck or rafters
  • Cracked or displaced ridge caps
  • Water stains spreading across ceilings
  • Daylight visible through the roof

Window and Door Failure

Windows and doors are the weakest points in a home's outer shell. High winds create pressure differences that can pop out glass or push doors inward. Once a window breaks, wind and rain enter freely, worsening interior damage.

Check for cracked glass, bent frames, or doors that no longer latch. Even a small gap lets water seep into walls and floors. After a storm, you should board up broken openings to keep out more rain, but leave permanent repairs to the pros.

  • Cracked or shattered panes
  • Bent or warped door frames
  • Doors that stick or won't latch
  • Broken seals around windows
  • Water stains on interior walls near openings
  • Gaps where the frame meets the wall

Foundation and Sill Damage

Floodwater saturates the soil around your foundation, causing it to shift or settle unevenly. This can crack concrete, push up floors, or tilt the whole structure. Older homes with pier foundations are especially vulnerable to movement.

Look for new cracks in walls, uneven floors, or doors that no longer close. A sagging corner or a gap between the wall and the floor suggests the foundation has moved. Do not enter a home if you see large cracks or shifting; have a professional assess it first.

Wood Rot and Mold

Heavy rain soaks into framing lumber, especially around windows, doors, and roof edges. If the wood stays wet, rot can start within days. Mold grows even faster, often hidden inside walls. You might smell it before you see it.

Structural wood that has rotted loses strength and may need replacement. A water damage inspection can find hidden moisture using tools like moisture meters. If you feel unwell from mold exposure, see a doctor. The pros can dry out the structure and replace damaged wood.

  • Soft or crumbly wood near windows
  • Dark spots on drywall or wood surfaces
  • Musty odor inside rooms
  • Visible mold on baseboards or studs
  • Warped or buckled floorboards
  • Peeling paint that hides rot underneath

Interior Water Damage

Water that enters through the roof or windows soaks drywall, insulation, and flooring. Wet drywall sags and may collapse, while soaked insulation loses its R-value and can harbor mold. Even after the storm passes, trapped moisture keeps damaging your home.

You can remove wet carpets and cut away soaked drywall to help drying, but structural repairs often require a professional. A local water damage pro can dry the framing and assess what needs to be replaced. Act quickly to limit the spread of mold and rot.

Frequently asked questions

How soon should I inspect my home after a storm?

You can do a visual check from outside as soon as it is safe, but do not enter a damaged structure. Look for obvious signs like missing shingles or broken windows. Wait for a professional to check the roof and foundation before going inside.

Can I fix structural damage myself?

Small tasks like boarding up windows are fine, but replacing load-bearing walls or repairing a sagging roof is dangerous. You need the pros for that work. They have the tools and experience to handle structural repairs safely.

Will my insurance cover storm damage?

Policies vary, and your insurer decides what is covered. Flood damage is often separate from wind damage, so check your policy carefully. Document all damage with photos before any cleanup, and keep records of any temporary repairs you make.
