Practical Example: Planning a 10×12 Shed Roof

Imagine you are building a 10 ft wide by 12 ft long shed with a roof rise of 3 ft and a 1 ft overhang.

1. Enter the dimensions: Width = 10 ft, Length = 12 ft, Roof Rise = 3 ft, Overhang = 1 ft.
2. Click Calculate Roof.
3. The results might show:
   • Slope: 0.60 (rise/run ratio)
   • Rafter Length: 5.39 ft
   • Roof Area: 145.36 sq ft

This instant calculation helps you estimate the required roofing materials and ensures your rafters fit perfectly.
