How to Find the Pitch of a Roof

What is roof pitch?

A: Roof pitch (or slope) is the angle of a roof, expressed as a ratio of vertical rise to horizontal run (e.g., 4:12 = 4 inches of rise per 12 inches of run).

Q: How do I measure roof pitch?

Method 1: Using a Level & Tape Measure

  1. Place a 12-inch level horizontally on the roof.
  2. Measure vertically from the level’s end to the roof (e.g., 6 inches = 6:12 pitch).

Method 2: Online Pitch Calculator

  • Upload a roof photo to apps like RoofSnap or Pitch Gauge.

Why is roof pitch important?

A: It determines:

  • Drainage efficiency (steeper = better water runoff)
  • Material compatibility (e.g., shingles need at least 2:12 pitch)
  • Snow load capacity (low-pitch roofs hold more snow)

What’s the best pitch for a metal roof?

  • Minimum: ¼:12 (for standing seam)
  • Ideal: 3:12 or steeper for optimal performance.
