# Roof - Sheathing cost

The **Roof Sheathing Cost** calculator computes the approximate cost of 4x8 sheets to cover the area of a roof based on the length and width of the area covered by the roof, the pitch of the roof and the unit price of 4x8 sheets (e.g. plywood or OSB).

**INSTRUCTIONS:** Choose your preferred units and enter the following:

- (
**W**) Width of the area covered by the roof. - (
**L**) Length of area covered by the roof. - (
**P**) The pitch of the roof. - (
**uP**) The unit price of the roof sheathing boards (see Unit Pricing below)

**Total Sheathing Board Cost:** The calculator returns the total price of sheathing boards in U.S. dollars. However, this can be automatically converted into other currency units via the pull-down menu.

#### General Information

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 ( roof - area (one side) ) separately.

### Unit Pricing

One should always use the local pricing available for constructions. However, for convenience a survey is periodically made for material costs. The following was identified for the price of 4x8 boards.

- The price of a 5/8" 4x8 plywood board was observed at $Error processing constant: [Could not locate page KurtHeckman.PRICE plywood 4x8 5/8 inch 4ply cdx].
- The price of a 1/2" 4x8 plywood board was observed at $25.05 USD.
