The first steps of this lesson

Step 1: Roofing Work Has Its Own Fall Rules

The general California fall protection rule for personal fall arrest is falls of more than 7 1/2 feet, and it also covers sloped roof surfaces steeper than 7:12 (Title 8 Section 1670(a)), but its Note 3 sends roofing operations to Section 1730 instead. Roofing is split into two rule sets: residential-type roofing activities in Section 1731, and all other roofing in Section 1730 (1730(a) says it does not apply to residential-type work). So the first question on any roof is: which section governs this job?

Step 2: Residential-Type Roofing (Section 1731)

Residential-type roofing means roofing and re-roofing, including tear-off, on single-family homes, townhouses, duplexes, and similar structures, covering loading and installing roofing materials, insulation, integral sheet metal, and vapor barrier, but not building the roof deck. On slopes 0:12 up to and including 7:12, employees must be protected when the fall distance is 6 feet or more; on slopes steeper than 7:12 they must be protected regardless of height. Allowed methods are personal fall protection systems, scaffolding, safety nets, or guardrails, or a fall protection plan with safety monitors and controlled access zones only where the employer demonstrates that conventional methods are infeasible (Sections 1671.1 and 1671.2).
