Parapet Guardrails
Many parapet walls look like a barrier but aren't high enough to stop a fall. A parapet guardrail closes that gap with permanent protection for everyone on the roof.
- 1,100mm min. barrier height
- Galvanised steel
- Non-penetrative options
Turn a low parapet into real fall protection
A parapet guardrail is a permanent railing fitted on top of, or against the face of, an existing parapet wall to bring it up to a safe height.
They are typically specified where a parapet is too low, was never intended as a safety barrier, or varies in height around the roof. As collective protection, a parapet guardrail protects everyone who steps onto the roof, with no individual equipment or training needed.
Prevention comes before PPE
UK regulations follow a clear hierarchy: avoid work at height, then prevent falls with collective protection, and only then rely on personal equipment. A parapet guardrail sits at the prevention stage.
- Immediate roof edge safety for everyone on the roof
- No harnesses or training needed
- Always-on, passive protection
- Low maintenance and a long working life
- Improves compliance and reduces liability
- Keeps the parapet working as a firebreak between buildings
Types of parapet guardrail
Top-fixed
Bolted to the top of the parapet. Minimal roof footprint and a clean, discreet profile, ideal where space is tight.
Side-fixed
Anchored to the face of the wall, leaving the top clear. Keeps edge access and drainage routes open and suits narrow or irregular parapets.
Clamp-on / non-penetrative
Secured with adjustable clamps rather than bolts: no membrane penetration, no welding, quick to install.
Fold-down
Lowers out of sight when not in use, then locks upright for access. Suits hotels, offices and heritage buildings.
Where parapet guardrails are used
Anywhere an existing parapet doesn't meet current height or strength requirements.
Parapet guardrail or freestanding guardrail?
Both are permanent systems, but they suit different roofs.
Choose a parapet guardrail when…
You already have a parapet wall that simply isn't tall enough.
- A parapet exists but is below the required height
- A consistent look along the roof edge matters
Choose a freestanding guardrail when…
There is no parapet, or the roof must not be penetrated at all.
- No parapet wall exists
- Roof penetration must be avoided entirely — see Kee Guard
Parapet guardrail installations
Permanent roof edge protection on commercial, industrial and public buildings.
Standards that apply
A parapet can only act as a guardrail if it already meets the required height and load. Most low parapets need a guardrail added to close the gap.
We survey parapet height, wall condition and access frequency, then specify galvanised steel systems, powder coated to match your building where needed.
| Duty to prevent falls | Work at Height Regulations 2005 |
|---|---|
| Barrier height & loading | BS 6180 (generally 1,100mm min. at roof edges) |
| Freestanding non-penetrative systems | BS 13700:2021 |
| Fixing substrates | Concrete, brick or steel upstands |
| Handover | Testing, certification and documentation |

Frequently asked questions
Quick answers about parapet guardrail. Can't see yours? Our team is happy to help.
Can a parapet be used as a guardrail?
Only if it already meets the required height and load standards. Most existing parapets are too low, so a guardrail is added on top or against the face to bring it up to a safe height.
What are the rules for guardrails in the UK?
The Work at Height Regulations 2005 require falls to be prevented wherever reasonably practicable. BS 6180:2011 sets barrier heights (generally 1,100mm at roof edges) and loads, and BS EN ISO 14122-3:2016 covers permanent guardrails. BS 13700:2021 applies only where a counterweighted freestanding system is used instead.
What is a parapet railing?
Another name for a parapet guardrail: a permanent railing fitted to an existing parapet wall to raise it to a safe height.
Does a parapet guardrail damage the roof?
Not with a clamp-on system, which uses adjustable clamps rather than bolts. Top-fixed and side-fixed systems bolt into the parapet wall itself, not the roof surface.
What is the difference between a parapet guardrail and a freestanding guardrail?
A parapet guardrail is fitted to an existing wall that is too low. A freestanding guardrail such as Kee Guard is a self-supporting system used where there is no parapet at all.
How long does a parapet guardrail last?
Built from galvanised steel and properly installed, a parapet guardrail can last decades with routine inspection and maintenance.
