How Your Shingles Are Made

Most roofs are covered in them - 80% in the U.S.! - and we’re still hand-nailing ours. Shingles, specifically asphalt shingles, boast a cost-effective, lightweight and low maintenance way to keep your roof strong and doing its job.
But how are they made? What are they made out of that lets them be such a low maintenance and effective roof covering?
The typical asphalt shingles we use today have been used since the 1950s and, while some materials have changed, they are generally the same.
Composite shingles (another name for the common asphalt shingles) have a base foundation of fiberglass or organic felt made from recycled paper or wood cellulose fibers. “These fibers are reduced to a water-based pulp, formed into sheets, dried, cut into strips and wound onto rolls … the fiberglass membrane is made by chopping fine, glass filaments and mixing them with water to form a pulp, which is formed into a sheet,” according to Made How. After this, the water from the pulp is then extracted while a binder is applied.
After curing these mat and cutting them down to individual sizes, they are mounted and are moved into a dry looper. Moving through a presaturation chamber and then an asphalt filled saturator tank, the fibers of the shingles are coated.
Once the base is complete, the shingles are coated with an asphalt formula and then treated with weather resistant mineral granules.
