Study Notes
Pitched Roofs Overview
- Pitched roofs feature steep angles, allowing for effective water and snow shedding.
- Typically constructed with slick roofing materials to enhance drainage and prevent build-up.
- Hazards associated with pitched roofs include:
- Steepness leading to unstable footing for workers.
- Increased risk of slipping when wet or icy.
- Potential for loose or granular surfaces that might collapse underfoot.
- Loose or broken tiles can pose dangers to individuals below.
Types of Slope Roofs
-
Low Slope Roofs
- Defined as having slopes up to 3/12 (3 units vertical rise for every 12 units horizontal run).
-
Medium to High Slope Roofs
- Characterized by slopes ranging from 4/12 to 12/12.
- A slope of 12/12 corresponds to a 45-degree angle.
- Roofs exceeding an 18/12 slope are deemed too steep for safe access via roof ladders; alternative methods such as aerial apparatus or ground ladders are recommended for safety.
Types of Pitched Roof
-
Shed Roof
- The simplest design among pitched roofs, featuring a single sloping surface.
-
Gable Roof
- Composed of two inclined surfaces that converge at the highest point, forming a ridge.
