The short answer

Inspect Roof and Gutters

Start with the roof and gutters, since they handle most rain and snow. Look for missing, cracked, or curling shingles. Check for rust on flashing and any gaps where water could seep in. Clear leaves and debris from gutters and downspouts, and make sure downspouts direct water at least three feet away from your foundation.

A clogged gutter can cause ice dams in winter or overflow during heavy rain, leading to roof leaks and foundation saturation. If you cannot safely reach the roof, use binoculars from the ground or ask a pro for a roof inspection. Fix small issues now to avoid interior damage later.

Check Foundation and Drainage

Walk around your home and examine the foundation for cracks or gaps. Seal any openings with exterior caulk or concrete patch. Ensure the soil slopes away from the house so water does not pool against the walls. Check that downspout extensions are in place and not disconnected.

Poor drainage is a leading cause of basement and crawlspace moisture. If you notice standing water near the foundation after rain, adjust the grading or add a downspout extension. For persistent issues, a water damage inspection can identify hidden problems and recommend solutions.

  • Inspect for cracks wider than 1/8 inch
  • Clean and test sump pump if you have one
  • Verify window well drains are clear
  • Check that exterior faucets are shut off and drained before winter

Review Plumbing and Appliances

Look under sinks, behind toilets, and around water heaters for signs of moisture, rust, or dripping. Check appliance hoses for bulges or cracks, especially on washing machines and dishwashers. Replace any worn hoses before they burst. Know where your main shutoff valve is and test it once a year.

Slow leaks often go unnoticed until they cause drywall or flooring damage. If you find water stains or soft spots, address the source immediately. A plumber can fix pipe issues, and if water damage has already occurred, the pros can help with drying and repairs.

  • Tighten loose toilet handle to stop running water
  • Replace washing machine hose every 5 years
  • Insulate pipes in unheated areas
  • Check water heater for corrosion or leaks
  • Test water pressure to avoid strain on pipes

Inspect Attic and Crawlspace

During or after heavy rain, check your attic for water stains, damp insulation, or daylight coming through the roof. Look for mold or musty odors, which indicate persistent moisture. In crawlspaces, check for standing water, damp soil, or condensation on pipes. Ensure vents are open and not blocked.

These areas are prone to hidden leaks that can go unnoticed for months. If you find mold or significant water damage, do not disturb it. A mold professional can assess health risks, and water damage pros can dry and clean the space safely.

Maintain Doors and Windows

Check caulking and weatherstripping around doors and windows. Replace cracked or missing sealant to prevent wind-driven rain from entering. Look for gaps between the frame and wall, and ensure thresholds are properly sealed. In winter, condensation on glass can indicate high humidity or poor sealing.

Water intrusion around windows can lead to rot in the frame and wall. If you see staining on the interior sill, the exterior seal has likely failed. Reapply caulk as needed. For older homes, consider a professional inspection to catch issues that are not visible from the ground.

Frequently asked questions

How often should I do a seasonal inspection?

Aim for at least twice a year, ideally in spring and fall, before the wet season. After severe storms, do a quick walk-around to check for damage. More frequent checks are wise if you have an older home or a history of leaks.

What should I do if I find water damage during my inspection?

Stop the source of water first, such as turning off the valve or patching a small leak. Then dry the area thoroughly to prevent mold. For significant damage, contact water damage pros who can extract water, dry materials, and repair affected areas.

Can I prevent all water damage with regular inspections?

No inspection can prevent every issue, but regular checks catch most problems early. Sudden pipe failures or extreme weather can still happen. Inspections lower your risk and help you act quickly when issues arise.
