Skillion Roof Pitch Formula:
| From: | To: |
A skillion roof, also known as a shed roof or mono-pitched roof, is a single sloping roof surface. The pitch is the angle of the roof slope, typically measured in degrees. The minimum recommended pitch is 2.5° to ensure proper water drainage.
The calculator uses the trigonometric formula:
Where:
Explanation: The formula calculates the angle of the roof slope based on the ratio of vertical rise to horizontal run.
Details: Proper roof pitch is crucial for water drainage, structural integrity, and compliance with building codes. A minimum pitch of 2.5° is recommended for skillion roofs to prevent water pooling and leakage.
Tips: Enter the vertical rise and horizontal run measurements in consistent units (inches, feet, meters, etc.). Both values must be positive numbers with run greater than zero.
Q1: What is the minimum pitch for a skillion roof?
A: The minimum recommended pitch is 2.5 degrees to ensure proper water drainage and prevent leakage.
Q2: Can I use different units for rise and run?
A: No, both measurements must be in the same units (both in feet, both in meters, etc.) for accurate calculation.
Q3: What materials work best for low-pitch skillion roofs?
A: For pitches接近 minimum, use specialized roofing materials designed for low slopes, such as membrane roofing or standing seam metal roofing with proper sealing.
Q4: How does roof pitch affect drainage?
A: Steeper pitches allow water to drain more quickly, reducing the risk of water pooling and leakage. The minimum 2.5° pitch provides adequate drainage for most climates.
Q5: Do building codes specify minimum pitch requirements?
A: Yes, local building codes often specify minimum pitch requirements based on roofing material and climate conditions. Always check local regulations before construction.
