The short answer

Inspect Roof and Gutters

Your roof and gutters are your home's first defense against water intrusion. Twice a year, ideally in spring and fall, look for missing or damaged shingles, rusted flashing, and cracked sealant around chimneys and vents. Clear leaves and debris from gutters and downspouts so rainwater flows away from the foundation.

If you live in a hot, dry climate, your roof takes a beating from sun and heat. Cracks in the roof membrane or dried-out seals can appear quickly. A simple walk-around with a ladder and a hose test can reveal leaks before they become major problems.

  • Check for curled or missing shingles
  • Clean gutters and downspouts
  • Seal gaps around vents and chimneys
  • Trim tree branches overhanging the roof
  • Look for water stains on ceiling and attic
  • Test roof flashing after heavy rain

Check Plumbing and Water Heater

Plumbing failures are a leading cause of water damage. Inspect visible pipes under sinks, behind toilets, and around the water heater for corrosion, dampness, or small drips. Pay attention to the water heater's age and the condition of its connections, as these often fail without warning.

Know where your main water shutoff valve is located and make sure it works. If a pipe bursts, turning off the water quickly can limit the damage. If you live in Fresno, keep the shutoff valve location written down and share it with everyone in your household.

  • Look for rust or moisture on pipes
  • Test shutoff valves twice a year
  • Check water heater for leaks and sediment
  • Replace worn washers in faucets
  • Inspect washing machine hoses for bulges
  • Listen for hissing sounds near pipes

Seal Windows and Doors

Windows and doors are common entry points for water, especially during storms. Inspect caulking and weatherstripping around every window and exterior door. Replace any cracked or missing sealant to keep rain from seeping into walls and framing.

Water that gets behind siding or under thresholds can rot wood and attract mold. A simple bead of fresh caulk can save you from expensive wall repairs. Reapply sealant every few years, or whenever you notice drafts or water streaks on interior glass.

  • Replace cracked caulk around windows
  • Check weatherstripping on doors
  • Look for gaps in exterior siding
  • Test door thresholds for water entry
  • Inspect window frames for rot or staining

Maintain Landscaping and Drainage

The ground around your home directs water either away from or toward your foundation. Ensure soil slopes away from the house for at least six feet. Clean and extend downspouts so they discharge well clear of the foundation, and consider adding a rain barrel or French drain if water pools near the slab.

Overgrown plants and tree roots can clog drainage and push against walls. Trim bushes to allow airflow and keep soil from touching siding, which invites termites and rot. A dry, well-drained perimeter is one of the simplest ways to prevent crawlspace moisture.

  • Grade soil away from foundation
  • Extend downspouts at least five feet
  • Clean French drains and catch basins
  • Trim shrubs to avoid siding contact
  • Remove leaves from window wells
  • Inspect irrigation for leaks near walls

Prepare for Storm Season

Before the rainy season, inspect your roof, gutters, and yard for anything that could cause water to back up. Clear storm drains and make sure any drainage pumps, if you have them, are working. Stock sandbags or a portable pump if your area is prone to flooding.

If a storm does cause water intrusion, act quickly. Move belongings to a dry area, and document the damage for your insurance records. Policies vary, and your insurer decides what is covered. For thorough help, consider a water damage inspection to identify hidden moisture and prevent mold growth.

  • Test drainage pump before heavy rain
  • Clear storm drain covers
  • Store sandbags for flood-prone areas
  • Check roof flashing and seals
  • Move valuables to upper floors
  • Document any water intrusion with photos

Frequently asked questions

How often should I inspect my roof and gutters?

Inspect your roof and gutters at least twice a year, in spring and fall. After major storms, do a quick visual check for damage. Clear debris promptly to keep water flowing away from your home.

What should I do if I find a small leak?

If you find a small leak, fix it right away. Dry the area, remove any damaged material, and apply sealant or patch the roof. If the leak is extensive, contact a water damage pro to assess and dry the area to prevent mold.

Can seasonal maintenance really prevent major water damage?

Yes, regular maintenance catches small issues before they become big ones. Checking seals, plumbing, and drainage can stop water from entering your home. This reduces the need for costly repairs and keeps your home safer.
