Asphalt shingles are the most common type of residential roofing in North America (including the Seattle area), and they may also be found on roofs in a variety of other countries. Regardless of design or color, they are all made in much the same method, using a limited number of critical raw ingredients.
What goes into the creation of an asphalt roofing shingle?
A continuous sheet is used in the manufacturing process to provide a base for the materials to be applied on. The following are some of the materials:
Stable resins and binders are used to join thin fiberglass mats formed from glass fibers of a certain length and diameter. Asphalt roofing shingles are reinforced with them. Weather resistance, fire resistance, and a longer lifespan are all advantages of using fiberglass.
This is the key water-resistant component that keeps the granules on the shingle. The asphalt used is a byproduct of oil refining and has a similar origin as road asphalt, although it has been oxidized to increase toughness and weather resistance. Raising the viscosity of heated asphalt entails precisely blowing air through it. For enhanced weather resistance and to ensure that each shingle layer meets fire resistance criteria, a fine mineral powder is incorporated with the asphalt.
Asphalt roofing shingles are most known for their stone granular surface. These mineral grains are fired in a range of colors to help reflect the sun’s rays while also adding beauty to the roof.
