The Sheeting for a Roof calculator computes the number of 4x8 sheets (plywood or OSB) needed to cover a roof based on the length and width of the area covered and the pitch. The formula works for gabled roofs (two sided) and single sided roofs (see diagram).  For gabled roofs, this formula is only accurate if the both gables have the same pitch, which puts the ridge in the middle. For roofs with different pitches, calculate each side separately.

### Instructions

To use this calculator, enter the following:   Single and Double sided Gabled Roofs

• length of the area covered in standard units with feet as the  default.
• width of the area covered in standard units with feet as the  default.
• pitch in rise over run

### Outputs

This calculator computes:

• The number of 4x8s needed to cover the roof area.
