Review the calculated pitch in degrees or as a ratio.Visit a reputable online roof pitch calculator.Measure your roof's horizontal run and vertical rise, as described in the previous sections.Here are some steps to follow when using a roof pitch calculator: Simply enter the required measurements, and the calculator will give you the pitch in degrees or as a ratio. Roof pitch calculators are online tools that simplify the process of calculating roof pitch. How to Calculate Roof Pitch Using a Roof Pitch Calculator? The resulting ratio is typically expressed as X/12, where X is the rise for every 12 inches of run. Determine the ratio by dividing the rise by the run and multiplying by 12.To calculate roof pitch as a ratio, follow these steps: Use the formula: Angle = arctan (rise/run). Don't forget to convert the result from radians to degrees if needed.Ĭalculating roof pitch as a ratio is a simpler method often used in the construction industry. Use a scientific calculator to find the angle in degrees.Access the roof safely and measure the horizontal run (in inches).
Follow these steps to measure roof pitch in degrees: How to Determine Roof Pitch in Degrees?Ĭalculating roof pitch in degrees is a precise method that requires a few simple tools and a basic understanding of trigonometry. Now, divide the rise by the run, and multiply the result by 12 to express the roof pitch as a ratio of inches of rise per foot of run (e.g., 4/12, 6/12). Next, measure the vertical distance (in inches) from the roof's highest point to the same point used for the run measurement. Step 2: Measure the vertical distance (rise) Here's how: Step 1: Measure the horizontal distance (run)įrom the roof's edge, measure the horizontal distance (in inches) to a point directly below the roof's highest point. To calculate the roof pitch, you need to determine the rise and run of your roof. Understanding roof pitch is essential for various aspects of your roofing project, including material selection, drainage, insulation, and aesthetics. A higher pitch indicates a steeper roof, while a lower pitch denotes a more gradual slope. Roof pitch refers to the steepness or slope of a roof, which is expressed as a ratio of the vertical rise to the horizontal span.
