How to Use This Tool

For Roofing Contractors: Use this tool to convert between pitch and angle formats quickly. The slope factor is essential for calculating material quantities, and rafter length helps with framing calculations.

Key Metrics: Slope factor multiplies by roof area to get actual surface area. Rafter length per foot run helps calculate total rafter length.
