Rise and Run Roof Calculator

What is a Rise and Run Roof Calculator?

A Rise and Run Roof Calculator is a web-based tool used to calculate the rise and run of a roof and determine the pitch or slope of the roof.

It helps establish the ratio between the vertical rise (the height of the roof) and the horizontal run (the distance along the roof) to understand the roof’s slope and construction requirements.

Why Use a Rise and Run Roof Calculator?

Rise and Run Roof Calculators are used for the following reasons:

1. Design and Construction: To determine the roof’s slope, which affects the roof’s appearance and how it sheds water and snow.
2. Building Codes: Compliance with building codes and regulations often requires specific pitch or slope requirements.
3. Roofing Material: Helps in selecting appropriate roofing materials based on the roof’s pitch.

How to Use a Rise and Run Roof Calculator:

1. Open the calculator webpage.
2. Enter the vertical rise in inches, which represents the height of the roof.
3. Enter the horizontal run in inches, which represents the distance along the roof.
4. Click the "Calculate Roof Pitch" button.
5. The calculator will display the roof pitch as a simplified ratio.

Example Calculation:

Suppose you have a roof with the following specifications:

• Vertical Rise: 24 inches
• Horizontal Run: 96 inches

1. Enter these values into the calculator.
2. Click "Calculate Roof Pitch."
3. The calculator will display the roof pitch is Nan.
