Shed Pitch Formula:
From: | To: |
Shed pitch is the ratio of vertical rise to horizontal run of a shed roof. It determines the steepness of the roof and is typically expressed as a unitless ratio or sometimes as a fraction.
The calculator uses the simple pitch formula:
Where:
Explanation: The formula calculates the roof slope by dividing the vertical rise by the horizontal run.
Details: Proper roof pitch is essential for water drainage, structural integrity, and selecting appropriate roofing materials for your shed.
Tips: Enter both rise and run measurements in meters. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is a typical pitch for a shed roof?
A: Shed roofs typically have a pitch between 1:12 and 4:12 (rise:run), but this can vary based on climate and intended use.
Q2: How do I convert pitch ratio to degrees?
A: To convert pitch to degrees, use the formula: degrees = arctan(pitch). Most pitch ratios correspond to specific angle measurements.
Q3: Why is proper roof pitch important?
A: Proper pitch ensures water drainage, prevents leaks, provides adequate headroom, and meets local building code requirements.
Q4: Can I use different units of measurement?
A: Yes, as long as you use the same units for both rise and run, the pitch ratio will be the same regardless of the unit system.
Q5: What's the minimum pitch for different roofing materials?
A: Minimum pitches vary: asphalt shingles typically need 4:12, metal roofing can work with 3:12, while built-up roofs may require only 1:4:12.
