Porch Roof Slope Calculator

What is a Porch Roof Slope Calculator?

A Porch Roof Slope Calculator is a tool used to determine the slope (pitch) of a porch roof based on the rise (vertical height) and run (horizontal distance) measurements.

The result is typically expressed as a ratio like “1:X,” where X is the number of inches of rise for every 12 inches of run.

Why Use a Porch Roof Slope Calculator?

This calculator is useful for homeowners, builders, and designers to ensure that the porch roof has the desired pitch for aesthetic and functional reasons.

It helps in planning and construction, particularly when considering factors like drainage and snow load.

How to Use a Porch Roof Slope Calculator:

1. Enter the rise measurement in inches (vertical height of the porch roof).
2. Enter the run measurement in feet (horizontal distance along the porch roof).
3. Click the "Calculate Roof Slope" button.
4. The calculator will display the porch roof slope in the format of "1:X."

Example Calculation:

• Rise: 6 inches
• Run: 8 feet

Porch Roof Slope = (6 inches / (8 feet * 12 inches per foot)) ≈ 1:20

In this example, the porch roof has a slope of approximately 1:20, meaning for every 12 inches of horizontal run, the roof rises by 1 inch.
