Working on fragile roofs: Key risks and control measures

If work near fragile areas can’t be avoided, choose controls that prevent anyone stepping onto or falling through a fragile surface:

• Work from underneath the roof using a suitable platform where possible.

• Use a MEWP to complete the work without stepping onto the roof.

• If roof access is required, install physical protection such as: roof walkways, rooflight covers, perimeter edge protection and staging to spread loads.

• Use safety nets or harness system where guardrails or roof protection aren’t reasonably practicable.

If harnesses (fall arrest) are used, they must be properly managed. This includes:

• training and supervision,

• suitable anchor points,

• sufficient clearance to prevent impact injury in a fall,

• and a rescue plan that can be implemented quickly.

Safe access should be planned so people can get to the work area without crossing fragile zones. Routes and working areas should be clearly marked, with demarcation at least 2 metres from fragile areas wherever possible.

Anyone working on roofs must have the knowledge, skills and experience to do the job safely. Less experienced workers must be supervised by a competent person, and competence should be maintained through regular refresher training.

Training should reflect the actual risks and equipment used on site, commonly including:

• Work at Height (risk assessment, equipment selection, emergency arrangements),

• MEWPs, ladders, and PASMA (tower scaffolds) where relevant,

• PPE and correct use of fall protection equipment.

Just as importantly, every job needs an appropriate plan for emergencies, including how anyone will be brought to safety if something goes wrong.
