Firstly, measure the height and the length of your roof. The length of your roof is measure from one end to another end vertically to the side of your roof.

For the width, use a rope over the ridge of the opposite eave and mark the rope at both eaves. Divide the eaves in half and it equals the one side’s width of your roof. For the slope of your roofing, measure how high your roof raises vertically for example in a 12 inches horizontal, your slope would be 4 in 12 inches.
