Felt roofing is incredibly popular for commercial roofing, as well as domestic roofing on things like extensions and garages. New year is the perfect time to consider those home improvement jobs you have been planning. Including repairing or replacing that old felt roof. Here at Gilston Building Services we offer a variety of high quality roofing services. This includes built up felt roofing, and high performance felt roofing. As a result, we have produced this guide to help you choose a new felt roof this New Year.
Built up felt roofing
A glass fibre mat of fibres coated on each side with a bituminous coating is called felt. Building up layers of this felt, one on top of the other, and each one bonded to the next, is one of the more common ways to create a felt roof. This is known as built up felt roofing. This makes an incredibly waterproof material that can be used as roofing, to keep out the rain and withstand all weather conditions. The felt is generally finished off with a light sand, chippings or grit, to protect it from the sun. Alternatively, a mineral cap sheet may be used.
A good quality built up felt roof will generally last for about 15 years.
High performance felt roofing
High performance felt roofing differs from built up felt roofing in the type of mat that is used. While built up felt roofing uses a glass fibre mat, high performance felt roofing uses a polyester mat. This makes it both lighter and more flexible. As a result, high performance felt has become more popular for modern building work. It also lasts a lot longer too, with the average lifespan reaching 30 years, double that of a built-up felt roof.
