DIY inspection · Checklist

The 47-point homeowner roof inspection checklist.

Go through this list once a season. If anything is checked, document with a photo and note the date. After two consecutive seasons of unresolved findings, get a professional opinion.

Roof surface (run binoculars across each slope)

Look for these 12 items on every slope:

  • Missing shingles
  • Lifted or curled shingle edges
  • Cracked or split shingles
  • Bald patches where granules are gone
  • Color variation indicating prior repairs or moisture damage
  • Moss or algae streaks (note coverage percentage)
  • Cupping or clawing (middle of shingle bowing up)
  • Visible nails or staples sticking up
  • Gaps in shingle alignment
  • Sagging between rafters (visible undulation)
  • Punctures from fallen branches or debris
  • Bird, squirrel, or raccoon damage near eaves

Penetrations (each chimney, vent, skylight)

For each penetration, check 8 items:

  • Flashing intact and properly layered into shingles
  • Step flashing visible on chimney sides (not just caulk)
  • Counter-flashing into chimney mortar joint
  • Rubber pipe boots intact (no cracks or tears)
  • Plumbing vent caps in place
  • Attic vent screens intact (rodent/insect prevention)
  • Skylight seals visible and uncracked
  • Pitch pans (square boxes around posts/poles) filled and not pooling water

Edges and trim (around the perimeter)

9 items to verify on the perimeter:

  • Drip edge present and not corroded
  • Starter shingles visible at bottom edge
  • Gable rake trim secure and not bowing
  • Ridge cap shingles intact and aligned
  • Hip cap shingles intact (where two slopes meet at angle)
  • Valleys clean (closed-cut or open metal — no debris)
  • Eave overhang straight, not sagging
  • Fascia board solid (no rot, no peeling paint indicating moisture)
  • Soffit ventilation slots or vents unobstructed

Gutters and drainage

8 items along the gutter system:

  • Gutter properly pitched toward downspouts (no standing water)
  • Gutter not pulling away from fascia
  • Hangers visible every 24-32 inches
  • Joints sealed and not leaking
  • End caps in place and sealed
  • Downspouts secured and connected to extensions
  • Splash blocks or extensions directing water 3+ feet from foundation
  • Granules or shingle debris collecting in gutter (note quantity)

Interior signs (attic and ceilings)

6 items to check from inside:

  • No water stains on top-floor ceilings
  • No water stains on upper exterior walls (interior side)
  • Attic deck wood looks dry, no dark stains
  • No daylight visible through attic deck
  • Insulation dry to touch (especially around penetrations)
  • No mold or musty smell in attic

Documentation

4 items to complete the inspection:

  • Photographs of every concern, with timestamp
  • Notes on coverage percentages for moss/algae
  • Comparison photos to prior inspection (if available)
  • Calendar reminder set for next inspection (6 months)

FAQ Common questions

Frequently asked.

How long does a DIY inspection take?
First time, plan 45-60 minutes — you'll be slow on the first pass. After that, 20-30 minutes is plenty. Adding the attic check adds another 10 minutes. Total time investment: 30 minutes twice a year to potentially save thousands in deferred-maintenance damage.
What should I do with my inspection findings?
Photo + date everything, even if it's nothing. A multi-year photo archive is the single most powerful document you can have if you ever need to prove storm damage occurred (vs. pre-existing wear) for an insurance claim. If you find active leaks, structural sagging, or daylight through the deck, call a roofer this week.
