Asphalt shingles were invented in the United States, and were first placed on a house in 1901. By 1939, these asphalt shingles were the most popular home roofing material in the United States - with 11 million squares of shingles produced, and its dominance continues today.
Asphalt prepared roofing was actually invented in 1893, but it took a few years before it was perfected. It wasn't until 1901 that the shingles were actually cut into strips as one layer or multi-layer (otherwise known as tab) shingles.
It was in the 1950s that manually applied adhesives were first applied to the backs of the shingles, which helped to hold the shingles together and secure against high winds. (Shingles are nailed to the roof, but glued to each other.)
There are two types of base materials used for shingles - organic (waste paper, cellulose, etc) that is saturated with asphalt to make it waterproof. Inorganic base material consists of fiberglass, which are not that great to be used in cold-weather locations.
Many shapes of shingles are available, as well as textures, and they can be purchased in different qualities - for example in areas with heavy winds, you can purchase shingles that resist wind very well.
