1. What is Skillion Pitch?

Skillion pitch refers to the slope of a mono-pitch roof, calculated as the ratio of vertical rise to horizontal run. It is a dimensionless value that determines the steepness of a single-plane roof structure.

2. How Does the Calculator Work?

The calculator uses the simple pitch formula:

Where:

• \( Rise \) — Vertical height difference (meters)
• \( Run \) — Horizontal distance (meters)

Explanation: The pitch represents how many meters the roof rises per meter of horizontal run. A pitch of 0.25 means the roof rises 25 cm for every meter of run.

3. Importance of Pitch Calculation

Details: Accurate pitch calculation is crucial for proper water drainage, structural integrity, material selection, and compliance with building codes for skillion roofs.

4. Using the Calculator

Tips: Enter rise and run values in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical skillion roof pitch?
A: Typical pitches range from 0.1 to 0.3 (10-30% slope), depending on climate, roofing material, and architectural design.

Q2: How does pitch affect water drainage?
A: Higher pitches provide better water runoff and reduce the risk of leaks, while lower pitches may require special waterproofing measures.

Q3: Can I use different units for rise and run?
A: The calculator uses meters, but you can use any consistent unit as long as both rise and run are in the same units (the pitch ratio remains the same).

Q4: What's the minimum pitch for different roofing materials?
A: Minimum pitches vary: metal roofing (0.03-0.05), asphalt shingles (0.17), clay/concrete tiles (0.25-0.33).

Q5: How does pitch affect snow load?
A: Steeper pitches allow snow to slide off more easily, reducing snow accumulation and structural load on the roof.
