# Hip Roof Sheathing

The Hip Roof Sheathing Calculator (Imperial) is essential for accurately estimating the number of plywood (or OSB) sheets required for your hip roof project. This calculator considers hip roofs' unique characteristics, ensuring precise measurements and quantities. By inputting your building dimensions, eave overhang, roof pitch, and waste percentage, you can quickly determine the total plywood needed, including adjustments for waste.

Note: The calculation is based on 4' x 8' sheets = 32 square feet each.

#### Calculation

1. enter the length of the building in feet and inches
2. the width of the building in feet and inches
3. the eave overhang in inches
4. the roof pitch as a ratio (e.g., 6 for a 6/12 pitch)
5. enter the waste percentage to account for cutting and fitting

#### The Results

1. the total area of the roof in square feet
2. the number of plywood sheets needed
3. additional sheets of plywood needed to account for waste
4. the total number of plywood sheets required for the project

Using this calculator, homeowners, contractors, and DIY enthusiasts can effectively plan their sheathing projects, avoiding the pitfalls of over or under-buying materials. The detailed results help ensure you have all the necessary materials to complete your hip roof with precision and efficiency.
