Roof Tarp Size Calculator calculator can be used to determine the appropriate size of a tarp needed to cover a roof based on its length and width.
Learn how to use the Roof Tarp Size Calculator calculator and its working principles
If your roof is 20 feet long and 15 feet wide, the calculator will determine that you need a tarp that is 22 feet long and 17 feet wide.
The calculator adds 2 feet to both the length and width of the roof to ensure that the tarp fully covers the roof and has enough overlap to secure it properly.
