How roofing shingles are made?

To make shingles, a roll of organic felt or fiberglass mat is mounted and introduced into a dry shuttle. The material passes through a presaturation chamber, then passes into a saturator tank filled with hot asphalt, which coats the fibers. If necessary, the material passes through the wet loop machine.

Roofing Product Comparison Tool Every day, thousands of tons of raw and manufactured materials are delivered to loading yards and receiving docks at top-tier roofing plants in the United States. These materials will be transformed into high-quality durable roofing shingles and special products that have won the respect of countless industry professionals and homeowners.

Shingles made with asphalt as the main ingredient are the most popular shingles sold in the U.S. UU. Nowadays, and so, the asphalt used in these roofing facilities is processed to meet the strict quality requirements necessary to create strong but flexible shingles. Limestone rock, which usually reaches plants by truck or railway car, is processed by crushing mills to a fine limestone powder.

This powder is then mixed with the asphalt to make a product called infill coating. On the production line, miles and miles of rolled fiberglass mat that serves as the “backbone” of the shingles are unfolded and fed into a coating machine, where the filled coating, superheated to over 400 degrees Fahrenheit, is applied to the top and bottom of the mat to create a base sheet. Then come the shingle granules. Mined rock that has been sized for use as granules is subjected to a process in which a special ceramic coating is applied.

The coating is colored so that the granules create the desired tile colors, and these granules are designed to maintain their appearance over the life of the shingle. A thin layer of sand is applied to the base sheet as it is introduced into a press that embeds the granules. As the sheet passes through a series of rollers, a fine mist of water is sprayed onto it, and the evaporative effect of water removes heat from the sheet. A sealant strip is then applied to the sheet to protect the roof tiles from wind damage.

To verify the actual color, texture, or appearance of the product, ask to see the actual product, available through a CertainTeed contractor or distributor. Thin fiberglass mats made of glass fibers of a specific length and diameter are bonded together with the help of stable resins and binders.

They are used to reinforce asphalt shingles. This fiberglass adds weather protection, increased fire resistance and a longer service life to the roofing material. The production process includes a continuous sheet, which is the basis on which asphalt and other materials are bonded. Asphalt roofing shingles can also be reinforced with a fiberglass mat, which is made of glass fibers connected with binders or stable resins.

Fiberglass is placed in large rolls in the factory and then “unrolled” when the production process of roofing shingles begins. Another term for asphalt shingles is composite shingles. The base of the tile base is made of wood and paper or fiberglass. Fiberglass is preferred since it is fire resistant but also lighter.

This mat is then covered with tar that comes from natural deposits or a by-product of crude oil refining. Once the base is coated, fly ash or finely ground limestone is added. This material acts as a stabilizer and makes shingles more durable and resistant to fire. Modern roofing shingles come in a variety of styles and materials, including slate, wood slats, metal, and composite materials.

So what exactly is needed to make an asphalt roofing shingle? The manufacturing process uses a continuous sheet that provides the basis on which the materials are applied. They are selected, processed and designed to work together to make a roofing material, that is, weight by weight, among the best value options available. Therefore, although there is a short list of raw materials in asphalt roofing shingles, each has a key purpose. They are sourced, processed, refined and designed to work together to create a roofing product that is durable, water and fire resistant, lightweight and among the best value options available to today's homeowners.

Every day, thousands of tons of raw and manufactured materials are delivered to loading yards and receiving docks at top-tier roofing plants in the United States. Because the asphalt coating of a roofing shingle is also a sticky material, the bottom should be covered with a material known as the “back surface” to prevent the shingles from sticking to each other in the packaging and adhering to the process rollers during manufacturing. These mineral granules are processed into a variety of colors by firing ceramic to help reflect the sun's rays while adding beauty and style to the roof. These asphalt adhesives are specially designed to ensure that they are activated at the desired temperature ranges and maintain their bond during the rigorous shingle installation process in the case of laminates, as well as during wind events and other roof tensions.

Often obtained from fine sand or limestone-like rock, this fine mineral powder is visible on the back of asphalt roofing shingles. Asphalt shingles remain the dominant roofing option in North America, and are found on roofs in dozens of countries around the world. A type of thermally activated asphalt sealant is used to bond the shingles together on the roof. Fiberglass is rolled into large rolls at the fiberglass factory, which are then “unwound” at the beginning of the roofing tile manufacturing process.

The asphalt on the roof has to be “rusted” by blowing air through the hot asphalt, increasing its viscosity. . .
