Roof Pitch Calculator

The roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12. If your roof pitch is greater than 3 your roof is considered pitched. Read more about roof pitch at Wikipedia.

This free roof pitch calculator will take your roof width (see the picture) and rise (the height of the roof) and will calculate the roof pitch both as numeric value and as a degree.

Optionally you can use it as roof cost calculator if you also happen to know the average cost per square foot in your area.
