Do I Need A New Roof?

Evaluating Key Danger Signals

Does your roof need repair or replacement? Look carefully for the following signs of a failing roof, like:

  • Leakage in the attic after wind-driven rain or ice build-up
  • Blistering and peeling of interior and/or exterior paint
  • Stains, mold, or mildew growth on interior ceilings and walls
  • Exterior decay of sheathing and/or siding
  • Missing, cracked, or curled shingles

View examples of these conditions.

How To Inspect For Damage

It is a good idea to inspect your roof regularly, particularly if you live in areas of the country that experience extreme weather. You can inspect your roof yourself, either by climbing on your roof or by using binoculars from the ground.

If you choose to go up on the roof yourself, remember to always utilize proper safety equipment to prevent falls or injury. See our Safety section for more details.

Here are just some of the ways to inspect for damage:

  • Check flashing for damage or for inadequate coverage
  • Look under eaves and overhangs for damage that might mean water leakage
  • Examine shingles for any that are missing, cracked, curled, torn, or warped
  • Look for any open seams or joints that could lead to leaking
  • Look for popped or rusted nails, or stains around nails
  • Check for unevenness, sagging, or unsound areas
  • Inspect your sources of roof ventilation—are they clogged, do you have ventilation, is there enough ventilation?
  • Inspect gutters for sagging, signs of leaks, and accumulation of granules
  • Check for dark patches or growth
  • Check around pipes and roof penetrations to make sure they are sealed and in good shape
  • Look inside the attic for signs of leaks, dark spots, holes, or sagging sheathing

For those who are uncomfortable with the idea of walking around their roof, the safest and most thorough option is to contact a professional roofing contractor to do the inspection.
