Shed Roof Square Metres and Perimeter

Calculate the square footage of a Shed style roof using imperial measurements.

The Shed Roof Area and Perimeter Calculator will help you accurately calculate the roof area in square metres and the perimeter of a shed roof in lineal metres using metric units. It considers various inputs, including building dimensions and roof slope, to provide precise calculations for roof area and perimeter.

Length B has to be the wall that slopes for this calculator to work.

Calculator

1. length A of the building in metres
2. length B of the building in metres
3. the overhang on the sides of the building in millimetres
4. the overhang at the front of the building in millimetres
5. the overhang at the rear of the building in millimetres
6. the roof angle in degrees

Results

1. the area of the roof in square metres
2. the perimeter of the roof in lineal metres
3. the length of the two sloped sides of the roof in metres
4. the slope of the roof in a rise-over-run ratio (rise in 12)
5. the slope of the upper roof as a percentage
