Roof slope conversion table.

Finding the best roof slope conversion chart. Example slope as grade. Finding the calculations needed to take things a step further with the roof conversion or development is going to take a lot of time and you need to have access to the best charts and software possible.

To obtain an accurate roof pitch measurement properly measure the rise and run. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.
