Definition :
- Roof pitch is the steepness of a roof expressed as rise over horizontal run.
- A flat roof has zero pitch, while all other roofs are pitched.
- Pitch is commonly expressed as inches of rise per 12 inches of run.
- For example, a 6-in-12 roof rises 6 inches for every 12 inches of run.
- Pitched roofs provide better drainage during heavy rain.
- They prevent water accumulation and reduce structural stress.
- Pitched roofs are commonly used in factories, warehouses, and hilly regions.
- Roof pitch depends on climate, roofing material, and building span.
Uses :
- Redirects rainwater and snow effectively.
- Provides protection from environmental elements.
- Helps in insulation and thermal control.
- Improves roof durability and lifespan.
- Supports use of different roofing materials.
Formula :
- Result = Rise / (Run / 12)
- Slope (%) = (Rise / Run) × 100
- Angle (Degree) = tan⁻¹ (Rise / Run)
