How to find the pitch of a roof?

The pitch of your roof is a determining factor when it comes to the cost of replacement and even the type of material that should be on your roof. For example, if your roof has a pitch that is too low then shingles might not be the way to go. You would likely need a material for flat roofs.

How do you find out the pitch?

The angle, or pitch, of a roof, is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally. For example, a roof that rises 6 inches for every 12 inches of the horizontal run has a 6-in-12 pitch. Here’s an easy, safe way to determine the pitch from inside your attic:
  1. To measure the roof pitch, you’ll need an 18- or 24-inch level, a tape measure, and a pencil.
  2. First, measure 12 inches from one end of the level and make a mark.
  3. Then, in the attic, place the end of the level against the bottom of a roof rafter and hold it perfectly level.
  4. Now measure vertically from the 12-inch mark on the level straight up to the underside of the rafter, as illustrated. That measurement is the number of inches the roof rises in 12 inches.
