Roof Edge Protection

Falls from height remain one of the most serious workplace hazards.

Where workers need to access rooftops for maintenance, inspection or servicing, unprotected edges can expose them to significant risk.

Preventing Falls Before They Occur

Roof edge protection creates a physical barrier that stops workers from accidentally reaching exposed edges.

This prevents the fall rather than attempting to arrest it after it has started.

Protecting Multiple Workers

Guardrails provide collective protection for everyone within the protected area.

Workers do not need to repeatedly connect and disconnect from the system during normal use.

Supporting Routine Maintenance

Commercial roofs often require regular access for:

• HVAC servicing
• Solar panel maintenance
• Roof inspections
• Drainage maintenance
• Cleaning
• Plant servicing
• Communications equipment

Permanent edge protection allows these tasks to be carried out more safely and efficiently.

Reducing Reliance on PPE

Where suitable guardrails are installed, workers may not need to rely on harnesses or lifelines solely to protect the roof perimeter.

This can simplify maintenance procedures and reduce user error.

Different roofs require different approaches.

Freestanding Roof Edge Protection

Freestanding systems use counterweighted bases rather than mechanically fixing every guardrail upright into the roof structure.

They are particularly useful on suitable flat roofs where avoiding penetrations of the waterproofing membrane is desirable.

Benefits can include:

• Minimal roof penetration
• Faster installation
• Reduced disruption
• Compatibility with many existing roofs
• Straightforward retrofit

Fixed Roof Edge Protection

Fixed guardrails are mechanically attached to a suitable structural element or roof system.

These can be appropriate where:

• Structural attachment is available
• Roof space is limited
• Counterweights would obstruct access
• A permanent engineered fixing is preferred

Folding Roof Edge Protection

Folding guardrails can be lowered when roof access is not required.

They are commonly selected where:

• Building appearance is important
• Planning or visual considerations apply
• Guardrails should be less visible from ground level

When rooftop access is required, the guardrail is raised into its protective position.

Roof Edge Protection for Narrow Spaces

Some rooftops contain extensive plant, solar equipment or restricted walkways, leaving limited space for conventional counterweighted systems.

Compact guardrail solutions can provide permanent collective protection while using less roof area.

Temporary Edge Protection

Temporary edge protection is used for short-term activities such as:

• Construction
• Refurbishment
• Roof replacement
• Temporary maintenance projects

Temporary systems should be selected according to the working environment and project requirements.

Collective Fall Protection - Guardrails protect everyone in the designated area without requiring individual connection.

Prevents Falls - The barrier prevents workers from reaching exposed edges.

Supports Frequent Roof Access - Permanent systems make routine maintenance more efficient.

Reduces Reliance on PPE - Workers may not need harness-based protection solely for the protected roof perimeter.

Permanent and Temporary Options - Solutions are available for both long-term maintenance and short-duration work.

Can Be Retrofitted - Many systems can be installed on existing buildings.

Modular Design - Guardrail layouts can often be configured around plant, access points and unusual roof geometries.

Suitable for Different Roof Types - Fixed, freestanding and clamped configurations allow protection to be specified for a wide variety of roofs.

Integrates with Other Safety Systems - Roof edge protection can work alongside walkways, step overs, skylight protection and personal fall protection.

Roof edge protection should be specified within the wider requirements governing work at height.

Work at Height Regulations 2005

The Work at Height Regulations require duty holders to follow a hierarchy of controls.

Where reasonably practicable:

1. Avoid work at height.
2. Prevent falls where work at height cannot be avoided.
3. Minimise the distance and consequences of a fall where prevention is not possible.

Collective protection should be considered before relying solely on personal protection where appropriate.

Roof guardrails support the prevention stage by physically protecting exposed edges.

BS 13700:2021

BS 13700 provides requirements relevant to permanent counterweighted guardrail systems.

Its application can include considerations such as:

• System design
• Performance
• Testing
• Installation
• Inspection
• Site-specific wind loading

Where a counterweighted permanent guardrail is specified, the relevant system should be designed and installed in accordance with the applicable requirements.

EN ISO 14122-3

EN ISO 14122-3 relates to stairs, stepladders and guardrails used as permanent means of access to machinery in relevant applications.

EN 13374

EN 13374 relates to temporary edge protection systems.

It should not be treated as the universal standard for every permanent roof guardrail installation.

BS 13700 & Wind Loading

Wind exposure is an important consideration when designing permanent freestanding roof edge protection.

A generic guardrail layout should not simply be assumed to be suitable for every building.

Factors affecting the design can include:

• Building height
• Geographic location
• Roof exposure
• Wind pressure
• Parapet height
• Guardrail position
• Roof shape
• Counterweight layout

A properly designed system should account for these site-specific factors.

Warehouses - Large warehouse roofs frequently require maintenance access for drainage, solar panels, HVAC equipment and roof inspections.

Distribution Centres - Extensive flat roofs and plant areas make permanent collective protection especially useful in logistics environments.

Manufacturing Facilities - Factories often contain extraction systems, ventilation equipment and other rooftop services requiring regular access.

Data Centres - Critical cooling and electrical infrastructure can require frequent rooftop maintenance.

Hospitals - Healthcare buildings rely on rooftop plant and building services that must remain accessible throughout the year.

Schools & Universities - Educational estates often contain multiple buildings requiring planned roof maintenance and contractor access.

Commercial Offices - Office buildings can use permanent edge protection to support routine facilities management and servicing.

Retail Properties - Shopping centres and large retail sites frequently have broad flat roofs containing HVAC systems and solar installations.

Logistics Centres - High-volume distribution sites benefit from permanent systems that simplify maintenance access.

Industrial Sites - Industrial buildings may require a combination of roof edge protection and other access systems around complex plant layouts.

Safesite provides complete roof safety and working-at-height solutions throughout the UK.

Our roof edge protection service can include:

• Roof safety surveys
• Risk assessments
• Fixed guardrail systems
• Freestanding guardrails
• Folding edge protection
• Narrow-space solutions
• Kee Guard® systems
• Professional installation
• Wind-loading considerations
• Integration with walkways and step overs
• Skylight protection
• Inspection and maintenance
• Ongoing technical support

Rather than treating the roof edge as an isolated hazard, we can assess how workers access and move around the entire rooftop.

This helps create a coordinated strategy covering perimeter edges, rooflights, access routes, plant areas and rooftop obstacles.
