Roof work-What you need to do

The law says you must organise and plan all roof work so it is carried out safely. Assessing all work at height

All work on roofs is highly dangerous, even if a job only takes a few minutes. Proper precautions are needed to control the risk.



Those carrying out the work must be trained, competent and instructed in use of the precautions required. A ‘method statement’ is the common way to help manage work on roofs and communicate the precautions to those involved.



On business premises contractors should work closely with the client and agree arrangements for managing the work.



Key issues are:



• Safe access to roofs

• Roof edges and openings

• Fragile surfaces



Everyone involved in managing or carrying out work on roofs should be aware of the following facts:



• High risk: almost one in five deaths in construction work involves roof work. Some are specialist roofers, but many are just repairing and cleaning roofs.

• Main causes: the main causes of death and injury are falling from roof edges or openings, through fragile roofs and through fragile roof lights.

• Equipment and people: many accidents could be avoided if the most suitable equipment was used and those doing the work were given adequate information, instruction, training and supervision.

Safe access to a roof requires careful planning, particularly where work progresses along the roof.



Typical methods to access roofs are:



• general access scaffolds;

• stair towers;

• fixed or mobile scaffold towers;

• mobile access equipment;

• ladders; and

• Roof access hatches.



Roof edges and openings



Falls from roof edges occur on both commercial and domestic projects and on new build and refurbishment jobs. Many deaths occur each year involving smaller builders working on the roof of domestic dwellings



• Sloping roofs: sloping roofs require scaffolding to prevent people or materials falling from the edge. You must also fit edge protection to the eaves of any roof and on terraced properties to the rear as well as the front. Where work is of short duration (tasks measured in minutes), properly secured ladders to access the roof and proper roof ladders may be used.



• Flat roofs: falls from flat roof edges can be prevented by flat roof safety systems – a secure double guardrail, balustrade system and toeboard around the edge.

Fragile surfaces



Always follow a safe system of work using a platform beneath the roof where possible. Work on or near fragile roof surfaces requires a combination of stagings, guard rails, fall restraint, fall arrest and safety nets slung beneath and close to the roof.



• Fragile roofs: all roofs should be treated as fragile until a competent person has confirmed they are not. Do not trust any sheeted roof, whatever the material, to bear the weight of a person. This includes the roof ridge and purlins.



• Fragile roof lights are a particular hazard. Some are difficult to see in certain light conditions and others may be hidden by paint. You must provide protection in these areas, either by using barriers or covers that are secured and labelled with a warning.
