Roofing Basics
A roofing square equals 100 square feet. Three bundles of standard shingles cover one square. Roof pitch affects total area and material quantity.
Roofing Materials
Common materials include asphalt shingles (most popular), metal, tile, and slate. Each has different lifespans, costs, and installation requirements.
Understanding Pitch
Pitch is expressed as rise over run (e.g., 6:12 means 6 inches of rise per 12 inches of horizontal run). Steeper pitches require more materials and careful installation.
