Fall Protection Engineering Works

A modular free standing roof edge protection system that does not penetrate the roof membrane.

Safe environment for all working on a roof

One of the HSE recommendations in reducing risk taken by people working on a roof is to select and use the right rooftop safety equipment. For contractors and engineers accessing flat roofs to carry out essential building, repair and maintenance work, safety guardrailing afforded by collective roof edge protection system can make a major contribution to minimising danger. The collective system that is selected must meet the highest safety standards. Our KeeGuard® rooftop guardrail system is fully tested and meets or exceeds current rooftop safety requirements. Not all free standing roof edge protection systems offer this level of security of rooftop areas.

KeeGuard® is a modular free standing rooftop guardrail system which does not penetrate the roof membrane. The system works on a proven counterweight system, recycled PVC weights provide high visibility, non-slip secure base that does not penetrate the roof membrane. Galvanised fittings and tube deliver collective protection which ensures a safe working environment for anyone working on a roof.

The KeeGuard® roof edge protection system offers maximum flexibility for most rooftop configurations, almost any flat roof up to 3 degrees can be accommodated. The system is available for different roof types, either for use where a restraining wall such as a parapet is in place or where the rooftop is completely open around the perimeter. The KeeGuard® rooftop guardrail system can be used for retrofitting to older buildings as well as for new constructions.

The KeeGuard® systems is also available in a lightweight aluminium version.

There is also available a newly launched KeeGuard® Foldshield folding version and a unique, fixed roof edge protection system named KeeGuard® Topfix especially designed for standing seam metal roofs.

General Questions

Are toeboards available on the KeeGuard system?

Yes, a toeboard can be supplied at the customer’s request.

Can KeeGuard be used as an anchor?

The KeeGuard system is not intended as an anchor and cannot be used as an anchor or tie off point to support any workers or equipment suspended off the roof.

Can the KeeGuard system be painted?

KeeGuard components can be painted by the customer before or after installation. KeeGuard components are also available powder coated in any RAL color at the customer’s request (extra charges apply for powder coating). Powder coating takes place prior to shipment.

Can the KeeGuard system be used to protect snow removal workers on rooftops in cold climates?

The design of the system allows for protection of the worker while allowing snow to be shoveled over the mid rail and off the roof.

Does KeeGuard need to be inspected or maintained after installation?

Once properly installed, the KeeGuard system is considered a permanent installation. We recommend that any fall protection system be inspected on a routine basis for maximum liability protection for the building owner.

Does the KeeGuard system comply with the current UK safety regulations?

The KeeGuard system has been tested to comply with all EU norms.

Does the KeeGuard system offer advantages over a horizontal life line system or harness system?

Yes. KeeGuard Roof Edge Fall Protection Railing System is a passive, collective fall protection system which is preferred by safety consultants. Lives have been lost in work related falls resulting from workers not using harnesses properly. The KeeGuard system removes the potential of that risk. Harness systems require training and proper and regular use. The embedded anchor for a harness system could later leak and cause costly water damage. The worry of not enough harnesses for rooftop workers is eliminated.

How do I buy the KeeGuard system?

Each KeeGuard System is individually engineered for your premises. For further information, call 0118 931 1022 to speak to our KeeGuard sales desk.

How does the KeeGuard system stay on the roof if it isn’t bolted through the roof membrane?

The system employs a tested and proven counterbalance system, the KeeGuard system(Patents in effect) is a roof edge railing fall protection system that keeps the workers on the roof without endangering the roof membrane itself.

How long does it take to install KeeGuard? Are special skills or tools required?

With the use of the new KeeGuard open style fitting (standard), two workers with minimal experience and simple hand tools can be installed up to twice as fast as most other systems. All materials should be delivered to the rooftop using a hoist, crane or other mechanical method. No power tools are required.

Is KeeGuard intended for temporary or permanent installation?

The system is intended as a permanent fall protection solution, however since it is a modular system, the system can be disassembled and moved if needed or for maintenance tasks.

Is KeeGuard more expensive than using a Harness/Tie Off system?

The installed cost of KeeGuard is competitive with horizontal life line systems.

Will installation of KeeGuard reduce insurance premiums?

Insurance premiums are often impacted by steps taken by the building owner to reduce hazards to their workers. More importantly, building owners’ liability will be strictly examined if an industrial accident occurs and preventative measures (such as KeeGuard) were not taken.

Installation Questions

Are all the materials used in the KeeGuard system protected from corrosion?

Galvanised, tube is used for vertical, horizontal and counterbalance supports and Kee Klamp components are all galvanized at our factory. The grub screws used to assemble the components and pipes together are all protected by Kee Koat® which is a special corrosion resistant coating. KeeGuard fall protection system is engineered using special components and is designed to withstand a full range of outdoor conditions.

Technical Questions

Can the KeeGuard system be installed on a sloped roof?

The system can be used on any style of flat roof with a slope up to 10 degrees.
