Roofing Materials Guide

Roofing is measured in "squares" where 1 square = 100 square feet. Shingles are sold in bundles, with 3 bundles typically covering 1 square.

Understanding Roof Pitch

  • Low pitch (2-4/12): Nearly flat, requires special materials
  • Medium pitch (5-8/12): Most common, easy to walk on
  • Steep pitch (9-12/12): Harder to work on, sheds water quickly
