Asphalt shingles are a type of wall or roof shingle that uses asphalt for waterproofing. Asphalt is a thick, sticky, black liquid or semi-liquid form of petroleum.
They are one of the most widely used roofing covers in North America because they have a relatively inexpensive up-front cost and are fairly simple to install.
EXAMPLE:
My neighbor remodeled his roof using asphalt shingles. Although there are many styles and colors, he choose a nice mixture of greys.
