Study Notes
Roof Sector Responsibilities
- Establish a Roof Sector during offensive fire operations to evaluate roof conditions and complete vertical ventilation
- Roof Sector officer must supervise crews and ensure safe operations
- Crews must enter the roof from an established safe area and have a secondary means to escape or reach a safe refuge on an unexposed and structurally sound roof surface
Roof Conditions Evaluation
- Evaluate roof conditions to assure structural soundness before attempting to work on it
- Consider the degree and extent of any signs of weakness before committing personnel above the fire
- Constantly re-evaluate roof safety throughout roof operations
Roof Sector Objectives
- Determine a safe working surface
- Complete ventilation cuts to achieve effective ventilation
- Coordinate/Communicate roof (vertical) ventilation with interior crews
- Coordinate roof fire control operations as directed by Command
- Maintain roof-top monitoring of roof structure and fire conditions
Commercial vs. Residential Roof Systems
- Distinct differences in construction design between commercial and residential roof systems
- Aware of differences that potentially impact roof operations
Special Roof Types
- Bowstring Roofs: no firefighter shall operate on or under a bowstring roof if the fire has penetrated the attic, involves the trusses, or the structure
- Metal Roofs: evaluate the pitch of the roof to determine if it is too steep to safely operate on
- Residential Tile Roofs: no firefighter shall operate on the roof of a residential structure fire covered with concrete roof tiles
- Commercial Tile Roofs: follow CALSSRC's standard operation for safe and efficient vertical ventilation operations
Roof Sector Duties
- Report to Command on roof design and construction, decking material, structural conditions, smoke/fire conditions, locations of fire walls and skylights, and heavy objects affected by fire conditions
- Provide progress reports to Command, including presence or absence of fire in the attic, smoke conditions, and changes in roof conditions and/or structural stability
