The short answer

Roof Weak Points

Your roof takes the first hit from wind, hail, and heavy rain. Missing shingles, cracked flashing, or worn seals around vents and chimneys let water seep into the attic and walls. Overhanging tree branches can scrape or puncture roofing material during high winds.

Check for loose or curling shingles, rusted flashing, and any visible daylight through the roof deck. Clean gutters and downspouts so water flows away from the roofline. If you spot damage, a local water damage pro can assess the extent and help you plan repairs.

  • Missing or cracked shingles
  • Damaged flashing around chimneys and vents
  • Clogged gutters and downspouts
  • Overhanging tree branches
  • Worn seals around roof penetrations

Windows and Doors

Windows and doors are entry points for wind-driven rain. Old caulking, cracked frames, or missing weatherstripping allow water to leak into walls and floors. During a storm, high pressure can push water through even small gaps.

Inspect the sealant around window and door frames, and replace any that is brittle or cracked. Ensure exterior doors have proper thresholds and sweeps. If water has already entered, a water damage inspection can reveal hidden moisture in the surrounding structure.

Foundation and Basement

Heavy rain can saturate the soil around your foundation, creating hydrostatic pressure that forces water through cracks in basement walls or floors. Poor drainage, such as downspouts emptying too close to the house, makes this worse.

Look for hairline cracks, efflorescence, or damp spots on basement walls. Make sure the ground slopes away from the foundation. If you notice standing water or musty odors, this may indicate a drainage issue that needs professional attention.

Attic and Roof Vents

Attics are vulnerable when roof flashing fails or when vents and exhaust pipes lack proper seals. During a storm, wind can drive rain into these openings, leading to soaked insulation and wood rot. Attic moisture often goes unnoticed until stains appear on ceilings.

Check attic insulation for dampness and look for water stains on rafters or the underside of the roof deck. Ensure that vents, such as bathroom or kitchen exhausts, are sealed and covered. If you find leaks, document the damage and consider a water damage assessment.

Gutters and Downspouts

Gutters and downspouts direct stormwater away from your home. When they are clogged with leaves or debris, water backs up and spills over the roofline, soaking the fascia, soffit, and walls. Ice dams in winter can cause similar issues.

Clean gutters at least twice a year, and inspect them for sagging or leaks. Make sure downspouts extend at least a few feet from the foundation. If water has damaged your soffit or fascia, wall water damage repair may be needed.

  • Clogged with leaves and debris
  • Sagging or detached sections
  • Leaking joints or seams
  • Downspouts discharging too close to the foundation
  • Ice dams in cold weather

Frequently asked questions

How do I know if my roof is at risk?

Look for missing or curled shingles, rusted flashing, and any signs of water stains on ceilings. Also check the attic for damp insulation or daylight through the roof deck. If you see any issues, a pro can inspect for hidden damage.

What should I do if water enters through windows?

Move valuables away from the area and dry the surfaces as soon as it is safe. Check the caulking and weatherstripping around the window for gaps. If water has soaked into the walls, a water damage inspection can identify the extent.

Can basement flooding be prevented?

Ensure gutters and downspouts direct water away from the foundation, and grade soil so it slopes outward. Seal visible cracks in basement walls, but note that serious flooding may require a professional evaluation. Act quickly to dry any wet areas to prevent mold.
