Thatch Fire Safety

Statistically, homes with thatched roofs are no more likely to catch fire than those with conventional roofs if the owner is made aware and understands the risk of thatch fire. However, if a thatched roof does ignite, a fire, if not caught in time, is almost impossible to control and the results can be devastating.

  • Normal fire safety advice applies in terms of switching off unnecessary electrical appliances and lights and of course extinguishing the likes of cigarettes.
  • Ensure that you have the correct fire extinguishers in the most suitable locations.

By raising awareness of common causes of thatch fires and by helping to promote the preventative measures that homeowners can take, it is possible to reduce the associated risks related to thatch fires.

Common Causes of Thatch Fires

Although thatch roof fires can be attributed to many different things, studies have been completed in to the most common causes and it is widely accepted that there are two main causes of thatch fires which are chimney related:

  • Ejected embers & sparks from the chimney
  • Chimney Fires

Many thatch fires have been accredited to wood burners, multi-fuel stoves, flue malfunction, insufficient chimney height and poorly maintained chimneys.

For many years, heat transfer was considered the main cause of thatch fires, however, recent research revealed that unless there is a partial blockage, for example a build-up of soot or a bird’s nest, which could divert hot gases through imperfections in the chimney stack, heat transfer is very unlikely to result in a thatch fire.
