Roof Pitch Calculator

How to Use the Roof Pitch Calculator

Using the Roof Pitch Calculator can help you determine important dimensions and metrics related to your roof design, such as the pitch ratio, pitch angle, pitch percentage, actual roof length, and roof area. Follow these steps for accurate calculations:

Step 1: Input Run Distance

Begin by entering the Run Distance. This is the horizontal distance in inches. Ensure that your input is between 1 and 1000, and specify the distance in increments of 0.25 inches for accuracy.

Step 2: Input Rise Distance

Next, input the Rise Distance, which is the vertical height in inches. Similar to the run distance, make sure your entry ranges from 1 to 1000 inches and conforms to the 0.25-inch step requirement.

Step 3: Input Roof Length

Proceed by providing the Roof Length in feet. Enter a value in the range of 1 to 1000 feet while ensuring your input is rounded to the nearest 0.1 foot.

Step 4: Input Roof Width

Finally, fill in the Roof Width in feet. The allowable range is from 1 to 1000 feet, and your input should be in 0.1-foot increments.

Step 5: Review Calculated Results

Once you have entered all the required input values, examine the following calculated results:

• Pitch Ratio: This indicates the ratio of rise to run distance, formatted as “Pitch is X:X”.
• Pitch Angle: The angle of the roof pitch in degrees, rounded to one decimal place and displayed with a degree symbol.
• Pitch Percentage: Provides the rise to run ratio as a percentage, calculated to one decimal place.
• Actual Roof Length: This is the actual roof length taking the pitch into account, calculated in feet and displayed to two decimal places.
• Roof Area: The total area of the roof in square feet, also calculated to two decimal places.

After reviewing the results, you can use these insights for your roofing project planning or any further analysis required.
