Roofing Material Guidelines

Roofing Terminology:

• Square: 100 square feet of roof area
• Bundle: Typically 1/3 of a square (3 bundles = 1 square)
• Pitch: Roof slope expressed as rise over run (e.g., 6:12)

Common Roof Pitches:

• Low pitch (1:12 to 4:12): May require special underlayment
• Medium pitch (5:12 to 8:12): Most common residential
• Steep pitch (9:12+): More material and labor intensive

Important Tips:

• Always add 10-15% waste for cuts and overlaps
• Hip roofs require more material than gable roofs
• Include ridge cap shingles in your estimate
• Consider underlayment, drip edge, and ventilation
• Steeper pitches require more materials due to increased area
