This roof shingle calculator requires four basic inputs.
Roof length measured in feet roof width measured in feet roof pitch.
The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.

The most common widths are 24 and 36 exposed but the actual width of the panel.
Things you will need steel tape measure.
