Falls account for over 36% of all construction fatalities. This detailed guide covers harness selection, anchor points, the 4:1 ladder rule, and how to run a fall protection pre-task plan before every shift.
Falls are the number one killer in construction — and roofing is the most dangerous trade of all. In 2023, falls accounted for 36.4% of all construction fatalities. Every single one of them was preventable. This guide covers everything a roofing contractor needs to build a real, effective fall protection program.
Understanding Your Fall Protection Options
OSHA allows roofing contractors to choose between three main fall protection systems: guardrail systems, personal fall arrest systems (PFAS), or safety net systems. For most residential and commercial roofing work, PFAS is the most practical choice.
Selecting the Right Harness
- 1Full-body harnesses are required — chest harnesses are not acceptable
- 2Harness must be ANSI Z359.11 compliant
- 3D-ring must be positioned at center of back between shoulder blades
- 4Inspect every harness before each use for cuts, burns, fraying, or deformation
- 5Replace harnesses that have been in a fall arrest event — they cannot be reused
Anchor Points: The Most Overlooked Element
An anchor point must support at least 5,000 lbs per attached worker — or be designed by a qualified person as part of a complete fall arrest system. Nailing a 2x4 to a truss is not an anchor point. Common compliant options include roof brackets, ridge anchors, and engineered temporary anchor devices.
Tip: Pre-Task Planning: Before any work above 6 feet, hold a 5-minute fall protection talk. Identify every leading edge, skylight, and opening. Assign each hazard a control method and confirm every worker is wearing their harness before climbing.
