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:
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.
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.
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.
