What Types of Damage Does a Hurricane Cause to Homes?
Last updated October 26, 2026
The short answer
Wind Damage to Roofs and Siding
Hurricane-force winds can lift shingles, tear flashing, and even peel back sections of roofing. Once the roof covering is damaged, rain finds its way into the attic and then into ceilings and walls. Siding on the outside of your home can also crack or blow off, leaving the wall structure exposed to the elements.
Wind can push debris like branches or loose objects into windows, doors, and exterior walls. A broken window lets rain and wind straight into your living space. After a hurricane, check your roof and exterior for visible damage, but be careful walking on wet or unstable surfaces. Local water damage pros can inspect for hidden issues.
- Check for missing or lifted shingles
- Look for cracked or broken windows
- Inspect siding for dents or gaps
- Note any debris that hit the house
- Take photos of damage for your records
Water Intrusion from Heavy Rain
Hurricanes bring torrential rain that can overwhelm gutters, downspouts, and drainage systems. Water may pool on flat roofs, seep under door thresholds, or flow through foundation cracks. Inside, you might see wet carpets, soaked drywall, or water stains on ceilings that indicate a leak from above.
Even a small amount of water can cause big problems if it sits for long. Drywall becomes soft and swollen, wood floors can warp, and insulation loses its ability to keep your home comfortable. Acting quickly to remove standing water and dry out affected areas reduces the chance of long-term damage.
If you live in Oakland, keep your shutoff valve location written down so you can stop water flow if a pipe bursts during a storm.
- Clear gutters before the storm
- Move valuables off the floor
- Use sandbags if flooding is likely
- Turn off electricity if water reaches outlets
- Document water levels with photos
Storm Surge and Flooding
In coastal areas, storm surge pushes ocean water inland, flooding homes with saltwater. Saltwater is especially damaging because it corrodes metal, ruins electrical systems, and leaves behind residue that attracts moisture. Even a few inches of floodwater can ruin flooring, furniture, and appliances.
Floodwater is often contaminated with sewage, chemicals, or debris, so avoid direct contact. Wear rubber boots and gloves if you must enter a flooded area, and wash your hands thoroughly afterward. See a doctor if you feel unwell after exposure. A professional flood cleanup can handle the dirty work safely.
Policies vary, and your insurer decides what is covered. Check your policy to understand what types of flooding are included.
- Do not walk in moving water
- Turn off gas if you smell a leak
- Remove wet items to dry them
- Open windows for ventilation if safe
- Do not use electrical appliances in wet areas
Structural Damage from High Winds
Strong winds can push against walls, causing them to shift or crack. In severe cases, roofs can partially collapse or entire sections of a home can be lifted. The force of wind entering through a broken window or door can also pressurize the inside, blowing out other parts of the structure.
Structural damage is not always obvious from the outside. You might notice doors that stick, cracks in drywall, or a ceiling that sags. These signs can mean load-bearing elements are compromised. A structural inspection by a qualified professional is wise before you re-enter a badly damaged home.
Water damage assessment helps identify which parts of your home are safe and which need repair.
- Look for cracks in walls or ceilings
- Check if doors and windows stick
- Inspect the foundation for gaps
- Watch for sagging rooflines
- Stay out if the structure looks unsafe
Mold Growth After Moisture
Hurricanes leave behind a lot of moisture, and mold can start growing within a day or two on wet surfaces. Mold thrives on drywall, wood, carpet, and fabric. You might notice a musty smell, dark spots on walls, or allergy-like symptoms such as sneezing and itchy eyes.
Drying out your home is the key to preventing mold. Remove soaked carpets and padding, open cabinets to let air circulate, and use fans or dehumidifiers if you have power. If mold covers a large area or you have health concerns, a mold professional can test and remove it safely.
- Dry wet areas within 24 to 48 hours
- Throw out porous items that soaked up water
- Wipe hard surfaces with a mild detergent
- Use a dehumidifier if available
- Wear a mask if cleaning moldy areas
Water damage does not wait
Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

How soon after a hurricane should I start drying my home?
Start as soon as it is safe to enter. The longer moisture sits, the more damage it does. Remove standing water and open windows if the weather allows. Run fans or dehumidifiers if you have power. Quick action reduces the chance of mold and structural rot.
Can I clean up floodwater myself?
Small, clean water spills can be handled with towels and a mop. But floodwater from outside may contain sewage or chemicals, so it is safer to let pros handle it. They have proper gear and equipment to remove contaminated water and dry your home thoroughly.
What should I document before cleanup starts?
Take photos and videos of all damage, including wet areas, broken items, and water levels. Keep receipts for any supplies you buy. Write down a list of damaged belongings. This documentation helps with insurance claims and lets pros understand what happened.
