How a non-penetrating guardrail works

BALLAST · BASE · RAIL · REPEAT

  1. 01

    Weighted base, no holes

    Each upright sits in a heavy steel or composite base that holds the rail upright by ballast alone — nothing is drilled into the roof, so the membrane and warranty stay intact.

  2. 02

    Modular rails clip in

    Top rail and mid rail sections drop between uprights and lock in. Runs are built to length and turn corners, so the system follows the actual roof edge.

  3. 03

    Collective protection

    A guardrail protects everyone inside it at once with no harness, lanyard or training to don — the highest tier of the fall-protection hierarchy for crews working near an edge.

  4. 04

    Reuse & relocate

    Break it down, stack the bases, move to the next roof. The same kit serves many jobs, which is why guardrail beats single-use roof anchors for repeat flat-roof work.

Why a non-penetrating guardrail

NO HOLES IN THE ROOF

Weighted bases hold the rail up by ballast, so there's nothing to drill, flash or seal — the membrane stays watertight and the roof warranty stays valid.

PROTECTS THE WHOLE CREW

Guardrail is collective protection: everyone inside the rail is protected at once, with no harness to fit or fall-clearance math to run. It sits at the top of the OHS control hierarchy.

Temporary roof guardrail for Canadian flat roofs

A non-penetrating guardrail is the simplest way to make a flat-roof edge safe without touching the membrane. Frontline's GUS guardrail kits use weighted bases and modular rail sections to build a continuous railing along the edge — no drilling, no anchors, no harnesses for the people working inside it. Because guardrail is collective protection, it sits at the top of the fall-protection hierarchy and is often the fastest way to get a crew compliant on a roof with HVAC service, inspection or repeat maintenance work.

Guardrail isn't always the right tool — tight edges, sloped roofs and single-point work still call for roof anchors and personal fall arrest. Many jobs use both. Pair a guardrail run with a complete kit and harnesses for the corners a rail can't cover, or compare the full Frontline range. Not sure how many feet you need?

Guardrail systems — common questions

ANSWERS YOU CAN CITE

01

Does a non-penetrating guardrail damage the roof?
No. Frontline GUS systems are held upright by weighted (ballasted) bases that simply sit on the roof surface — nothing is drilled, fastened or sealed. The membrane stays intact and the roof warranty isn't affected, which is why these kits are popular for finished and warrantied flat roofs.
02

How much guardrail do I need?
Measure the linear feet of exposed edge you need to protect, plus any returns around corners. The GUS75 covers about 75′ and the GUS10 covers about 100′; runs combine, so you can build longer perimeters from multiple kits. Call 437-475-2066 with your edge length and we'll spec the base and rail count.
03

Guardrail or a roof anchor — which do I need?
Guardrail is collective protection: it guards everyone inside the rail with no harness, so it's ideal for flat roofs, repeat maintenance and larger crews. Roof anchors with a harness and lanyard suit tight edges, slopes and single-point work. Many jobs use both — guardrail along the main edge and personal fall arrest for the corners a rail can't reach.
04

Where do Frontline guardrail kits ship from?
From Fall Protection Canada's warehouse in Paris, Ontario, to every province and territory — priced in CAD with no cross-border duties or brokerage fees. Call 437-475-2066 for a 24-hour quote on the footage and configuration you need.
