    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.
