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.
The information contained within the Safety Advice section of our website is offered as general guidance. Before considering your plan for any changes, you should first speak to your insurance company and gain a full understanding of their policy terms and requirements.
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.
Although thatch roof fires can be attributed to many different things, studies have shown that the most common, widely-accepted causes are chimney related:
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, such as 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
As with all matters relating to chimneys, you need to gain relevant and appropriate advice in relation to your chimney from the likes of HETAS and your insurance provider.
