Carport Roof Pitch Calculator. Find the inverse tangent of the pitch to find the angle in degrees. Check your results with the omni roof pitch calculator.
For example, if you measure 4 inches, the pitch of your roof is 4:12. Roof pitch calculator results explained. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
Cover width entry in meters eg.
This means that the rise of the slope goes up or down 8 inches for every 12 inches. To put it in perspective, the angle of this slope would be around 30 degrees. Roof pitch expressed in degrees: The minimum pitch for a roof is 1/4:12, which translates to 1/4 inch rise to 12 inches of run.
