Asphalt has been a great building material for thousands of years and this track all the way back to the ancient Mesopotamians. The early productions use in the United States cames as early as the 1890s, but was finally cut and sold as single shingles in 1903 by Henry M. Reynolds.

The production of asphalt starts with a machine that can add the necessary materials at the right time. First, the base material fiberglass goes through a dry looping process. Second, the base moves and one side is sprayed with hot asphalt in a saturated chamber, the asphalt is extremely hot at this point. Next, the shingle sheet is moved into a process to cool down called wet looping. From here it rolls into its next stage which it starts to add powdered minerals called coating. The product has one more step of additives which mixes inf granulates ceramic-minerals that cover the top and gives it the sharded exterior at times. During this phase, the desired color can be chosen for the shingle sheets. Finally, the sheets are cut into single shingles and ready to protect a home near you.
