How often to inspect your roof

Missing, cracked or curling shingles Lifted shingles let water in. Flashing Rusted or loose metal around chimneys, vents and skylights. Gutters Sagging or pulling away. Check from the ground with binoculars, and from the attic (water stains, damp spots, daylight through the roof deck). Leave the roof itself to a roofer.
What to look for from the ground and the attic. Leave climbing on the roof to a professional.

Inspect your roof at least twice a year, generally in spring and fall, and again after any high-wind storm. That's FEMA's recommendation for sloped roofs, and it adds that repairs should be made quickly once you find a problem.

The table below shows the spring and fall inspection months for your zone: spring after the thaw, fall before winter storms. Add a quick look after every major storm.

Why roof inspections matter

Your roof is the first line of defense against water getting into the house. Small problems like a lifted shingle or loose flashing can let water reach the roof deck, insulation and ceilings.

Storms make this more urgent. FORTIFIED, the roofing program of the Insurance Institute for Business & Home Safety (IBHS), reports that between 70% and 90% of insurance claims after severe weather include roof damage.

Roofs also wear out with age. FORTIFIED notes that roofs may need replacing every 15 to 20 years, sooner after harsh weather. Lifespan depends on the material, so ask a roofer what to expect from yours.

Spring and fall, zone by zone

In cold zones, the spring inspection comes later in the year, once snow and ice are gone. That's when you can see what winter did to shingles, flashing and gutters.

In hot and humid zones, the spring check gets the roof ready for summer storms and hurricane season. In every zone, inspect again after high winds, hail or a heavy storm.

See the table above for both months in your zone, and add your other seasonal tasks with the home maintenance calendar.

What to look for

You can spot most problems from the ground with binoculars, or from a window that looks onto the roof. FORTIFIED lists these warning signs:

Also look for sagging areas and for water pooling on the roof.

The attic view

Some roof leaks show up indoors before you can see them outside. FORTIFIED points to water stains on the ceiling of your home's top floor as a sign to get the roof checked.

If you have an attic you can enter safely, look at the underside of the roof deck with a flashlight. Signs to note:

Step only on framing members or a solid walkway. Ceiling drywall between the joists won't hold your weight.

How to inspect your roof, step by step

  1. Pick a clear, dry day with good light.
  2. Walk around the house and look at each roof slope with binoculars.
  3. Check shingles, flashing, vents and the chimney for the warning signs above.
  4. Look at the gutters and downspouts for loose sections and debris.
  5. Note any tree limbs that hang over the roof. FEMA recommends trimming them back.
  6. Check the attic and top-floor ceilings for stains or damp spots.
  7. Take photos of anything that looks wrong, with the date. They help when you talk to a roofer or your insurer.
  8. Schedule repairs quickly. Small fixes are easier than replacing a wet roof deck.

Ladder and roof safety

You don't need to walk on the roof to inspect it. Ground-level and attic checks are safer and catch most problems.

If you do use a ladder, follow OSHA, NIOSH and CPSC basics:

Never go on a roof that is wet, icy, mossy or steep. Stay off the roof right after a storm, when loose materials and hidden damage make footing unpredictable.

When it's a roofer's job

Call a roofer for anything you can't check safely from the ground, the attic or the bottom of a ladder. That includes steep roofs, roofs on two-story or taller homes, and roofs with tile or slate, which can break underfoot.

Also call a pro after storm damage, for any active leak or for flashing problems around chimneys and skylights. If your roof is near the end of its expected life, a professional inspection can help you plan ahead.

Clean gutters keep water moving off the roof and away from the house. See when to clean your gutters for the schedule in your zone.

If you have a fireplace, the chimney needs its own yearly inspection. See when to clean your chimney.
