Built-Up Roofs commonly referred to as “Tar and Gravel” are the oldest style of flat roofing. They are composed of layers of material covered by tar.
Once you have built up 4-6 layers, pebbles are spread over top to protect the coatings from the harmful UV rays of the sun.
Built-Up Roofs are generally heavier than most flat roofing products and you must make sure they comply with building codes. In some cases you may have to strengthen your roof trusses to support the weight.
