Understanding Roof Slope
Roof slope is a critical measurement that affects drainage, materials, and overall roof performance.
- Slope Angle The angle between the roof surface and horizontal plane.
- Pitch Ratio Rise in inches per 12 inches of horizontal run.
- Rise per Foot Vertical rise for each foot of horizontal distance.
Design Considerations
Climate Factors
Steeper slopes for snow and heavy rain areas.
Material Choice
Different materials require minimum slopes.
Drainage
Proper slope ensures effective water runoff.
Building Codes
Local requirements for minimum slope.
