How to Inspect Your Roof

According to the National Roofing Contractors Association (NRCA), you should inspect your roof at least twice a year – once in the spring and once in the fall. But when it comes to inspecting your roof, many homeowners wonder where they should start.

Interior Check

The best place to begin is inside your house – specifically your attic. Here are four things to look for on your attic ceiling (don’t forget to use your flashlight):

  1. Dark spots and/or trails
  2. Signs of water damage and/or leaking
  3. Sagging along the roof deck
  4. Places where outside light is showing through

Exterior Check

You’ll also need to check the exterior of your roof. When you do, look for things like damaged flashing, curling, blistering, rotting, buckling, and mold or algae growth (which looks like dark or greenish stains and is usually found in humid climates).

Exterior Roof Check

While inspecting, you should also:

  1. Inspect your roof for cracked, ripped, or missing shingles.
  2. Scan the roof for loose materials.
  3. Look for wear around chimneys, vents, or pipes.
  4. Inspect the gutters for shingle granules (which look like large grains of sand). If there is an excessive amount, it means your roof is over-worn.
  5. Check for signs of moisture, mold, and/or rot. (Wet spots may not be directly under shingles – it can travel down to its lowest spot before it drips.)
