Roof pitch angle calculator & slope factor chart showing different roof slopes and corresponding angles.

The roof pitch calculator calculates rise, run, slope, pitch, angle, and rafter length. Use the diagrams on this page when referring to the Input section and to interpret the calculated Results.

2024年7月31日 · Roof pitch is simply the slope created by the rafter. It can be assessed in two ways – either as the angle the rafter makes with the horizontal or the proportion between the …

2024年4月18日 · See our Roof Pitch Multiplier Chart for a much longer list of roof slope factors, including slope factors for roof pitches by the half-inch. We also explain the math behind the multiplier.

2022年1月5日 · Roof Pitch Calculator estimates roof slope from every possible angle. Calculate roof slope, area, rafters length and other dimensions. You can also convert roof pitch to Degrees (at the bottom). To estimate roof area, enter width and length (as shown in the measuring diagram below), and either Rise or Pitch – second value will auto-calculate.

2025年1月24日 · Calculate all aspects of your roof slope online. Output includes the angle, rise/run ratio, percentage and slope length with a simple form.

Calculate the roof pitch by entering the rise and the run. Our calculator will tell you what length rafters you need and will also convert the roof pitch to degrees and percents. Keep reading to learn even more about calculating roof pitch.

2023年10月31日 · Need to find your roof’s pitch for a project? This roof pitch calculator will do the math for you! We’ll also teach you to find your roof’s rise and run.

2023年8月21日 · Utilize our online tool to compute the roof angle. Find the angle, run, and roof pitch by inputting rise and slope values. Perfect for framing and construction.

The Roof Angle Calculator allows you to calculate the angle of a roof by entering the rise and slope of the roof to ensure you have a sufficient pitch to provide good rain water clearance from the roof.
