The short answer

Check Your Roof and Gutters

Your roof and gutters are your first defense against winter rain. Look for missing or damaged shingles, and clear leaves and debris from gutters and downspouts. Clogged gutters can cause water to back up under your roof, leading to leaks and water damage inside your home.

If you live in a mild coastal climate, wet winters mean keeping your roof and gutters clear is key. While you can inspect from the ground, a professional roofer can check for hidden issues. Addressing small problems now prevents larger, more expensive repairs later.

Protect Your Pipes from Freezing

Even in mild climates, a sudden cold snap can freeze pipes. Insulate pipes in unheated areas like garages, attics, and crawl spaces. Let a faucet drip during very cold nights to keep water moving. Know where your main water shutoff valve is and how to turn it off in an emergency.

If a pipe does freeze, turn off the water immediately and call a plumber. Never use an open flame to thaw a pipe, as that can cause a fire. Taking these steps helps prevent burst pipes, which can cause significant water damage to your home.

  • Insulate exposed pipes with foam sleeves
  • Disconnect outdoor hoses and shut off outdoor faucets
  • Keep garage doors closed to protect pipes inside
  • Locate and label your main water shutoff valve
  • Drip faucets during freezing temperatures

Inspect Your Sump Pump and Drainage

A sump pump is your basement's right companion during heavy winter rains. Test it by pouring water into the sump pit to make sure it turns on and drains properly. Check the discharge pipe for clogs and make sure it directs water away from your foundation.

Also inspect your yard's grading. The ground should slope away from your house so rainwater doesn't pool near the foundation. If you have a crawl space, check for standing water. Good drainage prevents water from seeping into your home and causing structural issues.

  • Test your sump pump with a bucket of water
  • Clear debris from the sump pit and discharge line
  • Ensure downspouts extend at least 3 feet from your foundation
  • Check that yard slopes away from your house
  • Install a battery backup for your sump pump

Seal Gaps and Cracks

Small gaps and cracks around windows, doors, and utility lines let cold air in and water in too. Use caulk to seal gaps on exterior walls and around window frames. Check door sweeps and replace them if they are worn. This helps keep your home dry and energy-efficient.

Pay special attention to areas where pipes or wires enter your home. Seal these openings with expanding foam or caulk. Not only does this prevent water intrusion, but it also keeps out pests. A quick walk around your home with a caulk gun can prevent winter damage.

Know What to Do After a Leak

Even with maintenance, leaks can happen. Act quickly to minimize damage. Move furniture away from the leak, place a bucket under it, and turn off the water if you can. Dry the area with towels and a fan if possible. The faster you respond, the less damage occurs.

If water damage is significant, contact local water damage pros for a water damage inspection. They can assess the extent of the damage and help with water damage cleanup. Document the damage with photos for your insurance claim. Policies vary, and your insurer decides what is covered.

Frequently asked questions

How often should I clean my gutters?

Clean your gutters at least twice a year, especially before winter. If you have many trees nearby, you may need to clean them more often. Clogged gutters can cause water to overflow and damage your roof and foundation.

What temperature should I keep my house in winter?

Keep your thermostat at 55 degrees Fahrenheit or higher, even when you are away. This helps prevent pipes from freezing. If you leave for an extended period, shut off the main water supply and drain the pipes.

Can I prevent all winter water damage?

No, you cannot prevent every possible leak or storm. But regular maintenance greatly reduces the risk. If damage occurs, quick action and professional help can minimize the impact and cost.
