Roof inspection checklist

Even though it’s always right above you, you probably don’t give a lot of thought to the roof on your home until it starts to leak. And by the time that happens, it could be too late to stop the water damage that can occur. An annual roof inspection can help prevent unwelcome surprises and help your roof last for many years to come.

While you can do your roof inspection on your own if you know what to look for, it’s always a good idea to enlist the help of a professional roofing contractor.

We’ve put together a helpful checklist to help you determine whether or not your roof needs to be repaired or replaced:


Your roof is composed of a number parts, all of which should be included in your inspection.

  • At a glance, are there any obvious signs of damage?
    • Visible structural damage
    • Standing water
    • Gutter blockage
    • Broken gutters
    • Dirt and debris
    • Damaged eaves
    • Rotting wood
  • Shingles that are curled, buckled, cracked, broken or blistered
  • Missing shingles
  • Rusting of flashing (this is the metal material that’s used to cover the joints in the roof)
  • Cracks in chimney or damage to mortar or flashing
  • Vents that are dirty, peeling, rusting or covered with moss
  • Clogged drains
  • Fascia (the board that runs along the roofline and holds gutters in place)
  • Skylights that are dirty, peeling, rusting or covered with moss
  • Loose or exposed nails
  • Sagging areas
  • Mold, moss or rot (can be a sign of decay or water damage)
  • Missing or cracked caulking (used to seal flashings)
  • Large amount of shingle granules in the gutters (indicating shingles are decaying)

Damage can also occur to the inside part of your roof. Look for:

  • Roof sheathing damage (the flat panels underneath the shingles that provide support for the rest of the roof)
  • Sagging between rafters
  • Ventilation issues
  • Light coming through cracks
  • Water staining or leaks on ceilings or interior walls
  • Mold caused by moisture
  • Peeling wall paper
  • Cracked wall or ceiling paint

If you find roof damage, be sure to act on it right away and have it repaired by a professional roofing contractor.
