Kee Step® stepover platforms
Sized to the obstacle, so a walkway can carry on over pipework, ducting and plant instead of stopping at it.

Roof walkways
Kee Walk® Rooftop Walkway System
Roof surfaces are hazardous, particularly in bad weather. Irregular surfaces, changes of level and obstructions all have to be navigated. Kee Walk® is an anti-slip platform that gives a safe, level route across the roof, taking obstructions and irregularities with it.

Features and benefits of Kee Walk®
- Controlled rooftop access — keeps people away from hazards and roof edges
- CE approved to EN 516 Class 1-C
- Glass-reinforced nylon treads with excellent UV stability — they do not go brittle in sunlight
- Treads fire-rated to Class HB of UL94
- Longitudinal sections under 9kg/m — handled by two workers
- CE marked under European Construction Products Regulation 305/2011
-
Tread construction and stepped sections, which let one run follow a change of level without a break.
Two tread options
Both grades withstand heavy use, so a team can move around confidently on any compatible roof surface.
- Nylon treads — raised and roughened sections for a secure anti-slip surface, with excellent UV stability
- Aluminium treads — just as durable, with a sleek modern appearance where the building demands it

Kee Walk with Guardrail: a protected route across the roof
Combine with guardrails for complete fall protection
The Kee Walk® with Guardrail system pairs the walkway with a guardrail, so the route across the roof is protected as well as level. It installs on many roofing surfaces, giving quick access to elevated areas without compromising safety.
- The combination complies with guardrail protection standards and removes the fall hazards normally associated with unprotected roof edges — useful where a walkway has to run close to the perimeter.

Need a safe route across your roof?
Tell us the roof type and where people need to get to, and we will design the run — including any stepovers and guardrail it needs.
How it works
From survey to handover
-
01 · SURVEY
FreeRoof route and traffic assessment
A surveyor walks the route people actually use, checks the roof profile and pitch, and sets where the walkway runs and whether it needs guardrail alongside it.
-
02 · QUOTE
Fixed priceA fixed price for the run
The measured route gives the exact tread count and fixing configuration, so the quotation covers the full run rather than a rate per metre.
-
03 · INSTALL
No hot workModular and non-penetrative
Kee Walk sits on the roof surface without penetrating the membrane. A typical run installs in a day or two, with no disruption below.
-
04 · HANDOVER
Audit-readyCertification and the paperwork
You receive certification to EN 516, the route drawing, a competent-person handover and the annual inspection date.

Is a walkway the right answer?
A good fit when
- People follow the same route across the roof regularly
- The surface is irregular, fragile underfoot or slippery in bad weather
- The route crosses changes of level or obstructions
- You want to keep foot traffic off the roof covering itself
Consider instead
- Kee Step® stepover platforms — a single pipe run or duct to cross, rather than a whole route
- Kee Guard® rooftop guardrail — the hazard is the edge, not the surface
- Fragile roof protection — rooflights and fragile panels need covering, not just avoiding

Walkways take daily foot traffic, and fixings, treads and stepover platforms all need checking on a cycle. Mantech runs scheduled inspection, testing and recertification contracts covering walkways alongside the rest of a building's fall protection, booking the next visit during the current one.
FAQs
Questions about rooftop walkways
The standard a walkway meets, whether it penetrates the roof, and crossing pipework.
What standard do rooftop walkways need to meet?
Kee Walk is approved to EN 516 Class 1-C and CE marked under the Construction Products Regulation 305/2011.
Does Kee Walk penetrate the roof?
No. It is modular and non-penetrative, sitting on the roof surface without piercing the membrane.
Can a walkway cross pipes and ducts?
Yes. Walkways drop into Kee Step® stepovers wherever the route meets pipework or plant.
How often should walkways be inspected?
Annually by a competent person. Mantech runs scheduled inspections of walkways alongside the rest of your fall protection.
