OSB Roof Sheathing Costs
Construction Item Description
Construction unit cost for installation of Oriented Strand Board (OSB) roof sheathing.
NOTE-- This unit cost handles any thickness of roof sheathing. It gets the thickness from the Structural Dimensions screen.
One square foot of roof sheathing area.
We figure that a carpenter can install about 80 square feet of sheathing per hour, with a little help from an unskilled worker.
One sheet covers 32 square feet, with 10% waste factor.
NOTE-- This waste factor is reasonable for remodeling and smaller projects. You may want to reduce it to 5% for new construction, where there is less cutting loss.
Goldenseal uses the calculated roof framing that it gets from the Roof Dimensions screen.
