Believe it or not but chimney related fires are fairly common – as much as 90%. Imagine a fire burning in the fireplace, especially on a windy day! The embers escaping out of the chimney can easily get blown on to the roof, thereby increasing the chances of starting a fire. In fact, loose embers inside the house may also be a threat to the safety of the people at home. This is why you need fire retardant thatching for your home.
