we are offering roofing shingles. a shingle roof is a roof that is covered with a type of material called shingles. one of the elements or factors that organizes this type of roof into its own category is the shape and functionality of the shingles themselves. shingles are generally flat and rectangular and they are applied from the base or bottom of the roof upwards. as they are applied the previous sheet or section of shingles is overlapped. this process of overlapping continues until the entire roof has successfully been covered from base to top.
