The roof multiplies the footprint by the slope from a rise over 12. Waste is applied once after that. One square is 100 sq ft, and the bundle count uses 3 bundles a square as the example on this page.

Why this exists

A footprint of 2000 with a rise of 6 per 12 and 10 waste is 22.4 squares. With waste that is 24.6, and the bundle estimate is 74.

The roof multiplies the footprint by the slope from a rise over 12. Waste is applied once after that. One square is 100 sq ft, and the bundle count uses 3 bundles a square as the example on this page.

How this page works it out

A footprint of 2000 with a rise of 6 per 12 and 10 waste is 22.4 squares. With waste that is 24.6, and the bundle estimate is 74. 2236 sq ft. One square is 100 sq ft, and three bundles a square is the example on this page.

The pitch is a rise over a run of 12. The roof multiplies the footprint by that slope. Waste is added once to that area, and the bundles use 3 bundles for each 100 sq ft square.

The slope and the bundle count are the example on this page, not a building rule. The numbers stay in this browser.
