Tips: Water can enter your home in more ways than most homeowners realize—through small cracks in the foundation, deteriorating siding, clogged gutters, poorly sealed windows, or improper grading around the property. Over time, even minor water intrusion can weaken structural materials, damage the foundation, promote mold growth, and lead to expensive repairs. The key to protecting your home isn’t waiting until damage is visible—it’s taking proactive, preventative measures before moisture has a chance to take hold. By focusing on your home’s exterior first line of defense, you can manage how water flows, where it drains, and how effectively it’s kept out. The following essential tips are designed to help safeguard your home’s exterior, preserve its structural integrity, and reduce the risk of long-term water damage.
Here are some tips for you!
Roof
- Check your roof to ensure the shingles, flashings or tiles aren’t missing, broken, cracked, curled or damaged in other ways.
- Make sure the vents, flues, chimneys, air conditioners, and evaporative coolers are properly installed and in good shape.
- Check for leaks around rooftop air-conditioning units, vents for exhaust or plumbing, or other specialized equipment.
- Cut tree limbs that hang above your roof so they don’t cling to shingles and trap moisture. Leaves or twigs can also clog your gutters.
Gutters and Downspouts
- Ensure these are clean, free from debris, and in good condition so that water can flow freely.
- Install metal screens to prevent leaves, twigs, silt and other debris from clogging the gutters and drainage holes.
- Ensure downspouts direct water at least five feet away from your home’s foundation. Install downspout extensions if needed.
Doors and Windows
- Check for leaks near the corners of your doors and windows. Signs of leaks include peeling paint, paint discoloration or swollen fram.
- Protect exterior doors and windows from the sun, rain, and snow by installing overhangs above them.
- Close your doors and windows to check for a tight fit. Look for cracks between the sash and frame of your windows.
- Repair or replace damaged flashing or weather-stripping around windows.
Walls
- Check and repair cracked or broken siding boards, bricks, stone or other masonry, as well as structural sheathing.
- Seal any openings from wiring, plumbing, phone, cable, and heating and air conditioning lines with foam or caulk. Repair any damaged or unpainted wood surrounding these openings.
- Check for signs of termite activity on the walls and the wooden structures around your foundation. Termites can eat wood, plaster, and even metal siding.
- Ensure that the exhaust vent doors properly open and close.
- Remove any shrubs and other landscaping features from along the walls.
- When irrigating the garden, avoid directing water towards the house to prevent excessive water near the foundation.

Water damage to home exteriors often starts small—clogged gutters, cracked siding, poor drainage—but over time it can lead to structural damage, mold growth, and expensive repairs. Proactive maintenance like directing water away from the foundation, sealing gaps, inspecting roofing and flashing, and managing landscaping drainage helps prevent moisture intrusion before it becomes a serious problem. According to FEMA, proper exterior drainage and routine inspections are key to reducing long-term water damage risk and protecting the integrity of your home.
