As long as it is installed correctly bitumen prevents moisture build up without needing constant maintenance. Torch down roofing consists of modified bitumen which is similar to asphalt. These rubber roofs have evolved since their conception. This membrane contains a core of nonwoven polyester mat that resists splits and tears.
