How Asphalt Shingles Are Made

 Shingles are manufactured through quite a complex process. Let’s see what it involves:

 

• Large rolls of fiberglass reinforcement are inserted into a storage device. They advance towards the impregnation and coating area.

 

• In the impregnation and coating area, the bitumen layer is applied on both sides of the fiberglass reinforcement. Natural mineral stabilizers, generically called "fillers", are added to the impregnation coating to improve physical and mechanical performance, as well as fire performance.

 

• The application of stone granules on the upper surface is the next step. Granules are obtained by crushing basalt; the coloring made by a ceramic process allows the coloring of the granules in mass, thus ensuring superior color stability over time.

 

• A protective layer is then applied to the bottom of the roller, to prevent it from sticking to the production line as well as to prevent subsequent sticking in the package, until installation.

 

• The layer of colored slate granules is pressed to ensure complete embedding and coating of the upper area of the fiberglass impregnated and coated with bitumen.

 

• After cooling, the soldering bitumen line is applied. This step is followed by the measurement of the roll and the cutting in the form of shingle plates. Shingles are packed, labeled, palletized and stored, until they are delivered to customers.  For some of the best roofing products look to a roofing company near me in Lafayette to check them out.
