Working on roofs is a precarious matter at the best of times, but if the roof’s integrity is compromised you need extra care to ensure workers are safe and protected from the many potential risks. Here’s our advice for carrying out this type of work efficiently and, most importantly, safely…

From December to March we can expect heavy rain, winds, snow and frosts. A good, sound roof is essential for staying warm and dry inside our homes and workplaces – but the winter weather is designed to test its integrity and will surely highlight every weakness.

Our natural response to this will be to get it fixed as soon as we possibly can, maybe to even try a DIY fix. Have you ever been tempted to climb onto a roof to fix a tile or slate, remove moss and clean roof lights or to repair a leak?

If so, please beware. It can be a highly dangerous activity: each year several people lose their lives in these circumstances, which makes for even starker reading when you realise that all of the fatalities were preventable. Many others have suffered serious accidents, including permanent and life-changing disabilities – so it’s not a task to be undertaken lightly.

Roof risks

Roof-related accidents can happen anywhere. While simply climbing onto a roof may seem like a quick and easy way to do a minor repair job or clean a roof light, it’s fraught with danger, particularly on a fragile roof, and should be avoided at all costs.

A fragile roof is one in which part of the roof can be easily broken or shattered, such as:

  • Brittle surfaces such as roof-lights and Perspex sheeting
  • Linear sheets on built up roofs
  • Unreinforced cement sheets including asbestos cement sheeting
  • Glass including wired glass
  • Wood wool slabs
  • Any other similar fragile roofing material

Roof-lights are a particular risk because they can be hard to identify due to weathering, or sometimes even because they’ve been painted over.

Preventing accidents

So we know now the risks, but how can accidents stemming from work on fragile roof surfaces be prevented?

Firstly, always assume that the roof is fragile unless you’re certain it’s not. Then before carrying out any work, carefully assess the site-specific hazards and risks, and identify what needs to be done to keep everyone safe.

Make sure that whoever you assign the work to is trained and competent: they may suggest an approach you didn’t think of.

It might be possible to carry out work from below the fragile surface, by using either a suitable working platform or a mobile elevated work platform (MEWP).

In summary:

  • Always pre-plan all roofing activities, even in emergencies
  • Use suitable equipment for the job and make sure its properly maintained
  • Use trained and experienced workers who are competent in carrying out this aspect of work safely
  • Ensure a high level of supervision by competent staff
