Study Notes
Flat Roofs
- Found on various buildings such as warehouses, factories, shopping centers, and schools.
- Fully horizontal roofs pose drainage issues, leading to water accumulation and deterioration.
- Most flat roofs are built with a slight slope to ensure proper drainage towards central drains.
- Heavy rainfall or master streams may overload flat roofs, increasing the risk of structural collapse.
- Flat roofs are easier for firefighters to work on, but they have hidden dangers, especially in low visibility conditions.
- Risks include accidental stepping off edges, stumbling over parapets, or falling through openings like hatches or skylights.
Pitched Roofs
- Designed primarily to shed water and snow, presenting unique challenges for firefighters.
- Steep pitch reduces secure footing; risk increases when roofs are wet, icy, or have loose textures.
- Dangers include falling debris like loose roof tiles that may slide off and create hazards below.
- Pitched roofs are categorized into low slope (up to 3/12) and medium to high slope (4/12 to 12/12).
- Roofs with slopes greater than 12/12 (45 degrees) are often too steep for roof ladders; aerial or ground ladders are safer options.
Common Pitched Roof Types
- Roof design is influenced by climate, function, and aesthetics, with several common styles:
- Hip Roof: Slopes in four directions, maintaining a similar slope to a gable roof.
- Gambrel Roof: Slopes in two directions with breaks in the slope, often used for attic or living space.
- Mansard Roof: Features breaks in the slope on all sides, can conceal fire hazards within the roof space.
Roof Types
- Gable Roofs: Comprised of two inclined surfaces meeting at a ridge, a very common design.
- Hip Roofs: Similar to gable roofs but slopes in four directions.
- Gambrel Roofs: Two sloping sides with breaks; provides usable attic space.
- Mansard Roofs: Characterized by breaks in the slope on all four sides, can create concealed fire travels.
- False mansard fronts may be added for aesthetic reasons, but can pose dangers, as they may collapse under fire conditions.
