4x8s for Shed Roof (TL): The calculator returns the number of 4x8s for the roof. The calculator also returns the square feet of the roof.
A Shed Roof is a roof with a single slope (see picture). Shed Roofs are used in simple agriculture buildings and state of the art modern buildings. The 4x8s for a Shed Roof calculator is meant to help with material estimates for a roof. The rafter length uses the pitch (rise over run) and the span, which is the width plus the two overhangs (front and back).
In all cases, confirm your estimates with a professional estimate and adhering to local building codes.
