Gargoyle Warning Lines
Rooftop warning line systems are designed for accessing areas of a flat rooftop that are nearing the roof edge (but not within 2m) to provide a visual warning to workers that are approaching a hazard. The system is freestanding, eliminating the need to pierce the roofing membrane which exposes your rooftop to potential leaks.
When a work area is enclosed by properly installed and maintained warning lines, work inside the area can be done without additional fall protection measures.
All products are customizable depending on rooftop layout
and applications and include:
- 30″ x 30″ Rubber mats to protect roof membrane
- Baseplates – X shaped galvanized steel flat bar
- Posts – 42″ Aluminum post secured to baseplates to support cable and flags
- Coated galvanized steel cable – 500 lbs breaking strength
- Flags – Powder coated metal flags
- Dimensions: L101” x W31” x H66” (257 x 79 x 168 cm)
- Designed to be a temporary warning line system
- Quick set-up, modular, free-standing
- Cost effective systems for interior or exterior demarcation
- Durable galvanized components and uprights
- Requires NO penetration of the roof membrane, therefore no leaks
- “Passive” fall protection system
- Provides site-specific coverage or provides full or partial perimeter coverage on a rooftop
- Can be utilized on a variety of applications from warning about upcoming roof edges to skylights

The Hierarchy of Fall Protection Solutions
Elimination of Hazards
- Whenever possible, remove the fall hazard itself.
- If there is no fall hazard, there’s no fall.
Passive Systems
- Do not require the use of Personal Protective Equipment or active participation from the worker.
- Include Guardrails or Netting Systems.
- A preferred choice for its ease of use without the need for additional training and PPE.
Fall Restraint
- Uses personal fall arrest equipment (harness, lanyard, a. anchor point) to stop the user from reaching the edge.
- This type of ttying-offi p the user from falling in the first place.
Fall Arrest
- When all other solutions are infeasible.
- Fall arrest uses the same equipment as fall restraint but the fall protection equipment engages after the fall happens
- When it engages, the equipment slows the workers descent, bringing them to a safe stop.
