Shed Roof Slope Angle

Often you express roof pitch as the ratio between the rise and the run in the form of x 12.

Shed roof slope angle.

Acceptable flat roof coverings include tin roof sheets and pre fabricated plastic sheets. That is the way that my engineering mind works. Easy rafters is designed to calculate shed roofs that are framed to a ledger board nailed against a vertical wall not freestanding shed roofs supported by walls at both ends.
