What is Roof Pitch Calculator ?

It is used to calculate the roof rafter length, pitch, slope, and angle of your roof based on the rise and run. The online free tool combines a roof slope calculator, a rafter calculator, and an angle calculator so that you can quickly calculate the needs for your roof constructions all in one place.

Examples of Roof Pitch Calculator

Following are the formulas on how to calculate roof pitch in degrees, angle,s and slopes.

Roof Slope = Rise / Run * 12

Roof Angle = Inverse Tangent(Rise / Run) in degrees

Rafter Length = Square Roof of (Rise2 + Run2)

Roof Pitch = Rise/Run *100

Given that,

Rise = 45 and Run = 5

Thus Roof Slope = 45 / 5 * 12

Roof Slope = 108.0

Thus Roof Angle = tan -1 (45 / 5)

Roof Angle = 83.6598082540901

Thus Rafter Length =Square Roof of (452 + 52)

Rafter Length = 45.277

Thus Roof Pitch = 45/5*100

Roof Pitch=900.0 %
