A sample is loaded to show the math. Replace it with your measured edge lengths.
Measure the eaves along the lower roof edges and the optional rakes along the gable edges, then enter each total below.
Measure all eave runs along the lower roof edges and add them together.
Optional: measure the sloped gable edges where starter strips will run. Enter 0 when rakes are not included.
Starter Strip Order Summary
This uses 100 linear ft per bundle and 10% waste. Compare that coverage with your package before you order.
Worked Examples
Gable roof
80 ft eaves + 60 ft rakes · 100 ft/bundle · 10% waste
Add the eaves and rakes first, then allow for waste. Two bundles give you 200 linear feet of labeled coverage.
Eaves only
120 ft eaves + 0 ft rakes · 120 ft/bundle · 10% waste
Even with a 120-foot bundle, 132 feet of waste-adjusted coverage means buying two bundles.
Small shed
40 ft eaves + 30 ft rakes · 100 ft/bundle · 10% waste
If your package lists a different linear-foot coverage, use that number in Advanced settings.
