The short answer

Wind Damage to Roof and Siding

High winds during a hurricane can lift shingles, tear off siding, and loosen flashing around chimneys and vents. Once the roof covering is compromised, rain can enter the attic and soak insulation, drywall, and wooden rafters. You might not notice the leak until water stains appear on ceilings or walls, which can happen days after the storm.

Inspect your roof before hurricane season begins. Look for missing or cracked shingles, rusted flashing, and gaps around roof penetrations like pipes and skylights. If you spot damage, a roofer can make repairs. After a storm, check your attic for damp spots and call a water damage pro if you find any moisture.

Flooding from Storm Surge and Rain

Storm surge can push ocean water into low-lying areas, while heavy rain can overwhelm storm drains and cause street flooding. Even if your home is not in a flood zone, intense rainfall can pool around your foundation and seep into crawl spaces or lower levels. Water can enter through cracks in the foundation, window wells, or door thresholds.

If floodwater enters your home, it can soak carpets, drywall, and personal belongings. Floodwater may contain contaminants, so treat it with caution. Do not wade through standing water if you have open cuts, and see a doctor if you feel unwell after exposure. Local water damage pros can help with flood cleanup, but prioritize your safety first.

Water Intrusion Through Windows and Doors

Hurricane-force winds can drive rain horizontally, forcing water through window frames, door seals, and even brick walls. Older windows with worn caulking or single-pane glass are especially vulnerable. Water can collect inside walls, causing wood rot and peeling paint that may go unnoticed for weeks.

Before a storm, check that all windows and exterior doors close tightly and that weather stripping is intact. You can apply temporary sealant around frames if you find gaps. After the storm, look for dampness around windows and doors. If you notice any, dry the area and consider having a water damage pro inspect for hidden moisture.

Mold Growth After Moisture Exposure

Mold can start growing within 24 to 48 hours after water exposure. Damp drywall, carpet, and wood provide ideal conditions for mold spores to multiply. Mold can cause musty odors, trigger allergies, and damage building materials. You might see discolored patches on walls or a fuzzy texture on surfaces.

If you suspect mold, do not disturb it, as that can release spores into the air. A mold professional can assess the extent and recommend safe removal. For small areas, you can clean with soap and water, but for larger infestations, professional help is wise. Always wear protective gloves and a mask if you attempt any cleanup.

Structural Damage from Saturated Ground

Heavy rain can saturate the soil around your home, causing it to expand and shift. This can put pressure on foundation walls, leading to cracks or bowing. In extreme cases, saturated ground can cause a foundation to settle unevenly, which may affect doors, windows, and even the roof structure.

If you notice new cracks in your foundation, sticking doors, or uneven floors after a storm, these could be signs of structural movement. A structural engineer or a water damage pro can assess the situation. Do not ignore these signs, as they can worsen over time. Acting quickly can prevent more costly repairs later.

Frequently asked questions

What should I do first after my home gets wet from a hurricane?

Your first step is to ensure safety. Turn off electricity if water is near outlets or appliances, and avoid standing water if you suspect contamination. Then, remove as much water as possible using pumps or wet vacuums. Policies vary, and your insurer decides what is covered. Call your insurance company to report the damage and ask about coverage.

How can I tell if my roof has a leak after a storm?

Look for water stains on ceilings or walls, which often appear as brown or yellow circles. Check the attic for damp insulation, wet wood, or light coming through the roof deck. Also, inspect the roof from outside for missing shingles or damaged flashing. If you find any signs, contact a pro for an inspection.

Is mold a risk even if I dried everything quickly?

Yes, mold can still grow in hidden areas like inside walls, under flooring, or in insulation. Even if surfaces feel dry, moisture can remain. Use dehumidifiers and fans to speed drying, and consider a professional moisture inspection if you have any doubt. Mold can appear weeks later, so stay vigilant.
