Tar and gravel roofs are used primarily on roofs with low slopes ranging from a little better then flat to somewhere around a 3-in-12. This type of roof is composed of alternating layers of roofing felt and hot. With conventional tar and gravel roofing the tar is covered with a thin layer of gravel to protect the tar from the harmful ultraviolet rays of the sun.
