1. What is the Shed Rafter Calculation?

The shed rafter calculation uses the Pythagorean theorem to determine the length of a rafter for a shed roof with a specific pitch. This calculation is essential for proper roof construction and material estimation.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

Where:

• Rise — The vertical height of the roof (meters)
• Run — The horizontal distance of the roof (meters)

Explanation: This formula calculates the hypotenuse of a right triangle, which represents the rafter length needed for a shed roof with the given pitch.

3. Importance of Shed Rafter Calculation

Details: Accurate rafter calculation is crucial for proper roof construction, ensuring structural integrity, and estimating material requirements correctly.

4. Using the Calculator

Tips: Enter the rise and run measurements in meters. Both values must be positive numbers. The calculator will compute the rafter length needed for your shed roof.

5. Frequently Asked Questions (FAQ)

Q1: What is roof pitch?
A: Roof pitch is the slope of a roof expressed as a ratio of vertical rise to horizontal run.

Q2: How accurate is this calculation?
A: This calculation provides the theoretical rafter length. In practice, you may need to add extra length for overhangs and cuts.

Q3: Can I use different units of measurement?
A: This calculator uses meters, but you can convert from other units before entering values (1 foot = 0.3048 meters).

Q4: Does this work for all roof types?
A: This calculation is specifically for simple shed roofs with a single slope.

Q5: Should I add a safety margin?
A: It's recommended to add a small margin (5-10%) to account for cutting waste and installation requirements.
