Roof Edge Protection: Guardrail & Warning Line Systems

Passive fall protection for flat and low-slope roofs — non-penetrating guardrail bases, posts, rails and warning line stanchions that keep crews back from the edge without tying anyone off.

Guardrail or warning line — which does my roof need?

Guardrail physically stops a worker at the edge; a warning line marks a boundary and is typically paired with a safety monitor or other controls under provincial OHS rules. Working inside the line on a pitched roof? Look at roof anchors and roofing fall protection kits instead.
