Asphalt shingles are an American invention, dating back to 1901. By 1939, 11 million squares were being produced. They are now the most widely-used method of roofing in homes across the country.
The shingles saw improvement in the 1950s, thanks to manually applied glues that helped prevent wind damage. By 1960, researchers discovered that the shingles would be damaged by hail 1.5 inches in diameter or more.

How asphalt shingles are made
There are two types of asphalt shingles: one with an organic base and one with a fiberglass base. In both instances, the back side of the shingle is treated with sand, talc or mica to prevent it from sticking to another one. The top surface is designed to block harmful UV rays.
Organic shingles are said to be less brittle than their fiberglass counterparts in cold weather, but they also have a higher risk of fire damage.
In areas in which the weather is consistent — either mostly hot or mostly cold — asphalt shingles will last for a longer period of time. But they shouldn’t be installed in temperatures of less than 50 degrees Fahrenheit, because the shingles need to have heat to bond together.
In order to keep your shingles for the longest time possible, you should occasionally have them checked for moss or debris buildup. Moss can cause premature deterioration, so it should be removed (using a sulfate or chloride solution that should be rinsed off afterward). Strips of zinc or copper can be applied to prevent moss or algae growth on your shingles.
Can asphalt shingles be recycled? In some cases, yes. But according to the Environmental Protection Agency, 11 million tons of asphalt shingle waste is generated every year in America. One issue pertaining to recycling is that asbestos was used in shingles that were made before 1980, so those cannot be reused safely.
