Roof Slope Formula:
| From: | To: |
The Roof Slope To Degrees Calculator converts roof pitch measurements from rise/run format to degrees. This conversion is essential for construction, roofing projects, and architectural design to determine the exact angle of roof inclination.
The calculator uses the trigonometric formula:
Where:
Explanation: The formula calculates the angle by finding the arctangent of the slope ratio (rise divided by run) and converting from radians to degrees.
Details: Accurate roof slope calculation is crucial for proper drainage, material selection, structural integrity, and compliance with building codes. Different roofing materials have specific slope requirements.
Tips: Enter rise and run measurements in inches. Both values must be positive numbers. The calculator will output the roof angle in degrees.
Q1: What is the difference between roof slope and roof pitch?
A: Roof slope is typically expressed as a ratio (rise:run), while roof pitch is often expressed as a fraction (rise/run). Both describe the steepness of a roof.
Q2: What are common roof slope angles?
A: Common residential roof slopes range from 4:12 (18.43°) to 12:12 (45°). Flat roofs are typically 2:12 (9.46°) or less.
Q3: Why convert slope to degrees?
A: Degrees provide a more intuitive understanding of roof steepness and are often required for engineering calculations and material specifications.
Q4: Can I use different units of measurement?
A: The calculator uses inches, but you can use any unit as long as both rise and run are in the same unit (feet, meters, etc.).
Q5: What is the maximum roof slope this calculator can handle?
A: The calculator can handle any positive values, but typical roof slopes range from 0° to 60°. Very steep slopes may require specialized construction techniques.
