Mastic asphalt is used on flat roofs because it is a tried and tested waterproofing membrane. It has been successfully used to waterproof flat roofs for more than 100 years. The success of this material as a waterproofing membrane has lead to it often been referred to as 'The King of Waterproofing' in the construction industry. It is a seamless system which is carbon zero rated. This combined with being 100% recyclable and easy to repair has made it a very popular material with specifiers.
