Defender Roof Edge Protection® is a cost effective free standing roof top safety railings system. The system can be used on flat roofs up to a 5° slope*. Defender will provide collective fall protection ensuring safety of all workers who need access to the roof area.
The Defender Roof Edge Protection® system utilises recycled PVC weights to support a freestanding counterbalance system which does not penetrate the roof surface. The system complies fully with the requirements of BS EN 13374, BS EN 14122 and BS 13700.
*Defender installed to BS13700 or EN14122 – max roof pitch 3 degrees. Defender installed to EN13374 – max roof pitch 5 degrees.
Non-penetrating roof guardrails with no requirement for fixings or drilling and subsequently no repair to the roof membrane, thereby preserving your roof warranty. The PVC counterweights provide necessary protection without causing water leaking or roof damage.
The system is quick and simple to install and its modular form allows the flexibility to cope with even the most demanding roof shapes. Two workers without specialised training can install about 9 linear meters of the system in 30 min.
Defender Roof Edge protection has been tested to meet current industry standards such as BS EN 13374 Class A and BS EN ISO 14122 part 3. Installations are wind speed calculated to ensure compliance with the BS 13700 standard.
The Defender Roof Edge Protection System operates on a counterbalance principle using curved PVC counterweights as the main component. The system features 1100mm tall factory pre-assembled uprights that include open cradle fittings allowing the handrail tube to be quickly dropped into place, instead of the time consuming process of being fed through several fittings as required with other systems. The cradle fittings speeds up assembly and saves cost.
Defender Roof Edge Protection is designed to withstand a maximum horizontal load applied perpendicular to the top rail of 300Nm or a single point load of 600Nm.
The BS 13700 standard, published in 2021, provides guidance for the design, performance, testing, and inspection of Permanent Counterweighted Guardrail Systems (PCGS). Any permanent free standing guardrail installed after July 2021 should be compliant with BS 13700. This means you need to take into account location, height of building and exposure level.
We offer a FREE wind calculation to the new BS 13700 standard and issues the FREE report upon purchase of a Defender Roof Edge Protection System.

Defender is the answer when a flat or low slope roof needs a permanent guardrail and nothing may be fixed through the membrane. The counterweights hold it down; nothing penetrates the roof. That makes it the usual choice for the buildings where the roof warranty matters and the roof is visited regularly for plant maintenance.
The three options above use the same uprights, rail and fittings. What changes is how much room the counterweight needs behind the rail and how the system looks. Economy is the straight line along a clear roof edge. Standard uses the shorter counterweight where plant, ducting or a kerb sits close behind the edge. Plus is for the roof that is seen, with curved uprights and a third rail. Send a roof plan and we will say which fits; often a roof uses more than one.
Defender is for membrane roofs. On trapezoidal sheet or standing seam, use the metal roof edge protection system, which fixes to a baseplate instead of using counterweights.
Every Defender installation is laid out for its own roof. To quote we need a roof plan with the protected edges marked, the building height, the site postcode for exposure, the roof pitch, and the roof build up (mineral felt, asphalt or sheet) so the correct pads are supplied. From that the technical team produces the layout, the wind calculation and the parts list. Defender is held in stock and supplied through UK distributors. Contact the technical team to start, or read six benefits of modular roof edge protection for the background.
No. Defender is a free standing system held in place by recycled PVC counterweights on a counterbalance arm. Nothing penetrates the roof membrane.
Defender is designed for flat and low slope membrane roofs. For trapezoidal sheet and standing seam roofs FastClamp supplies a fixed baseplate system instead; see edge protection for metal roofs.
Defender is supplied as a permanent free standing guardrail. Each installation is laid out and wind speed calculated for its own roof and location, and the calculation report is issued with the system.
The uprights arrive factory pre assembled and the rail drops into open cradle fittings, so a straight run goes up quickly with two people and a hex key. There is no welding, drilling or hot work.
