The Challenge on Commercial Roofs

Edge protection often obstructs wall
cladding, gutters, and other finishing work
on the roof - even when that work isn’t
near the edge. To keep your project
moving, Edge Flag can be installed before
the edge protection is removed, allowing
tradespeople to safely complete tasks like
screwing off, flashing, and cladding.

  • 1. Loosen existing screw

  • 3. Insert pigtails

  • 4. Run Flag Line

Frequently asked questions

Is the Edge flag system WorkSafe compliant?

This edge flag system also known as a ‘Bump Rail’ is within Worksafe guidelines ‘Best practice guidelines for working at height in New Zealand

Can you use Edge Flag as your sole form of fall hazard control? Or only in specific situations?

Only in low-risk situations where workers stay 2m from the edge and the roof is under 10°. Not a substitute for edge protection on high-risk sites.

How is the bracket fixed to the roof - does it penetrate the membrane or iron?

Loosen the existing roof screws and slide the Edge Flag Brackets into place before retightening.

Can Edge Flag be installed on any roofing profile (e.g.trapezoidal, corrugated, membrane)?

Yes - suitable for most metal profiles (corrugated, trapezoidal). Not recommended for membrane roofs without special fixings.

How long does it take to install 100m of Edge Flag with two people?

Two people can install 100m in 30–45 minutes.

Do you need any special tools for installation? 

No - just a impact driver

Can it be installed by apprentices, or does it require a certified installer?

Yes - installation is simple and safe under supervision.

What is the maximum spacing before the flag line begins to sag?

5m max spacing. 3m is ideal for tight flag tension.

How does it perform in high wind conditions?

Performs well in strong winds. Flexible poles absorb gusts. Check tension regularly.

Is it safe to leave the system installed for multiple weeks or months?

Yes - made to remain in place for weeks during ongoing roof work.

How far back from the roof edge must Edge Flag be installed to remain compliant?

2 metres back from the roof edge, per WorkSafe guidelines.

Does Edge Flag replace the need for a fall arrest system or harness?

No - Edge Flag does not replace a fall arrest system or harness. It’s a visual warning system only, used to mark safe zones on low-risk roofs. Fall arrest gear is still required if workers are within 2 metres of the edge or working at height in high-risk situations.
