DIY Roof Inspection Checklist

Use this simple roof inspection checklist to spot shingle damage, flashing issues, leaks, and gutter problems early.

Published by TheSiteMath for U.S. contractors and homeowners. Use this page for planning and estimating, then confirm final requirements with local code officials and qualified professionals.

Why Regular Roof Inspections Matter

Most roof problems start small and stay cheap only if you catch them early. Use this checklist to inspect the roof, note damage, and decide when to call a roofer.

  • Water stains often start with one missed detail
  • Small flashing gaps can turn into active leaks
  • Clogged gutters can back water under the roof edge
  • Storm damage is easier to document right away

A simple rule: Check the roof in spring, in fall, and after major storms.

Safety First

Before You Climb

Do NOT go on your roof if:

  • Roof is wet, icy, or covered in debris
  • Wind exceeds 15 mph
  • You’re uncomfortable with heights
  • Roof pitch exceeds 6/12
  • You’re working alone

Safety equipment needed:

  • Rubber-soled shoes (no flip-flops)
  • Safety harness for steep roofs
  • Sturdy extension ladder
  • Helper on the ground
  • Fully charged phone

Alternative: Many items can be inspected from the ground with binoculars or from an attic inspection.

Ground-Level Inspection

What to Look For From the Ground

Roof Surface:

  • Missing or curling shingles
  • Obvious sagging areas
  • Debris accumulation
  • Moss or algae growth (dark streaks)
  • Visible damage from storms

Gutters and Downspouts:

  • Gutters attached securely
  • No sagging sections
  • Downspouts directing water away from foundation
  • Shingle granules in gutters (sign of wear)

Flashings (Use Binoculars):

  • Metal around chimneys intact
  • Vent pipe boots not cracked
  • Valley flashing visible and straight
  • No rust or corrosion

Soffits and Fascia:

  • Paint not peeling
  • No visible rot
  • Vent openings clear
  • No animal entry points

Attic Inspection

Before Climbing on the Roof, Check Inside

Light and Ventilation:

  • No daylight visible through roof boards
  • Soffit vents unblocked
  • Ridge vents open
  • Attic fan working (if equipped)

Signs of Moisture:

  • No water stains on rafters or decking
  • No mold or mildew smell
  • Insulation is dry
  • No condensation on roof deck

Structural Elements:

  • Rafters straight and solid
  • No sagging between supports
  • Decking feels solid (no soft spots)
  • Chimney structure intact

Pro tip: Do attic inspection on a sunny day - you’ll see light leaks more easily.
