Rafter Rise Calculator

What is a Rafter Rise Calculator?

A Rafter Rise Calculator is a tool that calculates the vertical rise or height of a roof rafter.

It considers two key factors: the roof span (horizontal distance between the eaves and the ridge) and the roof pitch (the slope of the roof).

Why Use a Rafter Rise Calculator?

A Rafter Rise Calculator is useful for several reasons:

1. Accuracy: It provides an accurate estimation of the rafter rise, which is essential for precise rafter construction and installation.
2. Efficiency: It saves time by quickly determining the rafter rise without manual calculations.
3. Avoids Errors: It helps prevent mistakes in rafter height, ensuring that rafters fit the roof structure correctly.

How to Use a Rafter Rise Calculator:

1. Open the calculator webpage.
2. Enter the roof span in feet in the "Roof Span" input field. This is the horizontal distance between the eaves and the ridge.
3. Enter the roof pitch as a fraction (e.g., 4/12 for a 4-in-12 pitch) in the "Roof Pitch" input field. The pitch represents the slope of the roof.
4. Click the "Calculate Rafter Rise" button.
5. The calculator will display the estimated rafter rise in feet.

Example Calculation:

Suppose you have a roof with a span of 24 feet and a pitch of 6/12.

You want to calculate the vertical rise of a rafter for this roof.

1. Enter "24" in the "Roof Span" input field.
2. Enter "6/12" in the "Roof Pitch" input field.
3. Click "Calculate Rafter Rise."
4. The calculator will display the estimated rafter rise 12 feet.
