Built-Up Roof

A built-up roof system is one of the oldest, most durable and reliable roofing products. Sometimes called “tar and gravel roofs,” built-up roof systems usually consist of multiple layers of roofing fabrics where bitumen or asphalt is applied, while the surface contains an aggregate application. This type of roofing is typically used for new roof construction projects with low-slope roof systems. Although a built-up roof system may require more labor than a single-ply system, they offer low maintenance, easy repair, multiple layers of protection and exceptional performance in extreme weather conditions and high roof traffic.
