Your home shields you from Bellingham's famous rain, howling coastal winds, and everything else Mother Nature throws our way. But who's looking out for your home? Whether you've just moved in or been here for decades, knowing how to inspect your home's exterior isn't just about maintenance – it's about protecting your piece of the Pacific Northwest.

Roof and Gutters

Your first line of defense is your roof, which takes the brunt of every storm, scorching sun, and winter freeze. Scan for missing or damaged shingles—they might look curled, cracked, or darker than surrounding areas. Check your gutters, too—they're not just leaf collectors. Properly functioning gutters prevent water damage to your foundation.

Siding and Trim

Run your hand along your siding. Do you feel any soft spots? That's a red flag for water damage. Look for warping, cracks, or areas where the siding has pulled away from the house. Pay special attention to corners and joints - these vulnerable spots often show the first signs of trouble.

Windows and Doors

Press your hand against your window frames. Do you feel a draft? That's money slipping through the cracks. Inspect the caulking and weatherstripping around all windows and doors. Cracked caulk might seem minor, but it can let moisture seep in, leading to hidden structural damage.

Foundation

The bedrock of your home walks your foundation's perimeter, looking for cracks larger than a credit card. Note any areas where soil has pulled away from the foundation—this could signal drainage issues. Keep an eye on areas where downspouts deposit water—proper drainage is crucial for foundation health.

Landscaping

Keep tree branches at least 6 feet from your roof—they're highways for squirrels and other critters looking for a way in. Check that the soil slopes away from your foundation, about 6 inches down for every 10 feet out.

Essential Inspection Tips

  • Pick a clear, sunny day for your inspection
  • Bring a flashlight to check dark corners
  • Take photos to track changes over time
  • Keep a maintenance log
  • Mark your calendar for seasonal checks

Red Flags That Need Immediate Attention

  • Water stains on siding or around windows
  • Sagging gutters or roof lines
  • Cracks in the foundation wider than ¼ inch
  • Doors that suddenly stick or won't close properly
  • Mulch or soil touching your siding

Regular Checks, Lasting Protection

Regular inspections help you catch minor problems before they become expensive headaches. Make these inspections part of your seasonal routine, like spring cleaning or fall yard work. Your home is your most significant investment - giving it regular checkups is one of the smartest moves you can make as a homeowner.
