Understanding Roof Pitch
Low Pitch (1:12 - 3:12)
Requires special roofing materials. Common for flat or low-slope roofs.
Medium Pitch (4:12 - 6:12)
Most common residential roofs. Works with standard shingles.
Steep Pitch (7:12+)
Requires additional safety measures. More material needed.
Roofing Tips
- • Always order 10-15% extra material for waste and future repairs
- • Check local building codes for required underlayment and ventilation
- • Ice and water shield is recommended in cold climates
- • Hip roofs require more ridge cap than gable roofs
- • Consider roof color for energy efficiency in your climate
