The short answer
Start with a Ground Check
Stand back from your house and scan the entire roofline with binoculars. Look for missing, cracked, or curling shingles, as well as rusted flashing around chimneys and vents. Note any areas where the roofline sags, which can signal underlying structural issues.
After a storm, check for debris like branches or leaves that might have damaged the surface. If you see granules from asphalt shingles in the gutters, that suggests the shingles are aging. These clues tell you where to focus your closer inspection.
- Look for lifted or buckled shingles
- Check for rust spots on flashing or gutters
- Inspect for moss or algae growth on the roof surface
- Note any visible daylight through gaps
- Watch for granule loss in gutters
Inspect the Attic Thoroughly
Go into your attic on a sunny day, or use a flashlight to look for signs of water entry. Check the underside of the roof deck for dark stains, wet spots, or streaks that indicate leaks. Also look for mold or mildew, which often grows in damp, hidden corners.
Examine the areas around vents, pipes, and chimneys where the roof penetrates. Those are common leak points because the flashing can fail over time. If you notice any daylight coming through the deck, that's a clear sign the roof needs attention.
- Look for water stains on rafters or sheathing
- Check for mold or mildew growth
- Inspect around pipes, vents, and chimneys
- Feel for damp insulation or wood
- Look for rusted nails or fasteners
Check Seals and Flashings
The most vulnerable parts of a roof are the seals around projections like skylights, plumbing vents, and chimneys. Inspect the rubber boots and metal flashing for cracks, gaps, or separation. Even a small gap can let water in over time.
Look at the ridge cap and the valleys where two roof slopes meet. These areas take heavy runoff and often wear out first. If you see dried or cracked sealant, it's worth having a professional evaluate the condition. The wet winters in your area make these checks especially important.
Look for Interior Signs
Inside your home, check ceilings and walls for discoloration, bubbling paint, or soft spots. These often appear long before a full leak becomes obvious. Also feel the walls near windows and doors for dampness, which can indicate a roof issue that's traveling down.
Check the attic insulation for wet spots, and look for rust on nails or metal components. If you have a finished attic, examine the ceiling and any exposed wood. Catching these signs early helps prevent larger water damage.
Know When to Call the Pros
If you find signs of a leak, or if you're uncomfortable walking on a steep roof, contact local water damage pros for a thorough inspection. They have the training and equipment to spot subtle issues that you might miss. They can also help with repairs and water damage mitigation.
A professional inspection is especially useful after major storms or if your roof is older. With a mild marine climate that brings wet winters and dry summers, roofs take a beating during the rainy season. A yearly check, whether you do it yourself or hire help, can save you from costly repairs.
Water damage does not wait
Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

How often should I check my roof?
Aim for at least twice a year, once in spring and once in fall, and after any severe storm. The fall check is key before the rainy season starts. More frequent checks help you catch small problems early.
What tools do I need for a roof inspection?
You'll need binoculars, a flashlight, a screwdriver to test for soft wood, and a notepad. For attic checks, a moisture meter can help, but it's not essential. Always prioritize safety, so use a ladder with a spotter if you need to get close.
Can I repair a roof leak myself?
Small fixes like replacing a single shingle or sealing a small gap might be DIY. But if the leak is large, or if you can't find the source, call the pros. They have the skills to address the root cause and prevent further damage.
