How Asphalt Shingles Are Made

Asphalt shingles are a widely used roofing material, known for their affordability, durability, and ease of installation. Understanding their production process can offer insight into their quality and performance.

Raw Materials

The production of asphalt shingles starts with essential raw materials: fiberglass or organic felt, asphalt, mineral granules, and sealant. The fiberglass mat, used in most modern shingles, provides the structural integrity needed for long-lasting performance. Organic felt, though less common, serves a similar purpose but is derived from recycled paper products.

Fiberglass Mat

Fiberglass mats are created by bonding fiberglass strands with a resin. This mat forms the core of the shingle, providing strength and flexibility. The fiberglass mat is preferred for its lightweight nature and resistance to tearing, which contributes to the shingle’s overall durability.

Saturation With Asphalt

Once the fiberglass mat is prepared, it is coated with hot asphalt. This saturation process is crucial for making the mat waterproof. The asphalt also helps in binding the layers of the shingle, ensuring they remain intact and functional over time. The heating and coating process also enhances the shingle’s resilience to various weather conditions.

Mineral Granules

While the asphalt-coated mat is still hot, mineral granules are applied to its surface. These granules serve multiple functions: they protect the asphalt from UV rays, add color and texture, and improve fire resistance. The granules are embedded into the asphalt, forming a protective layer that contributes to the shingle’s aesthetic appeal and functionality.

Cooling and Cutting

The coated mats are then cooled to solidify the asphalt. Once cooled, the mats are cut into individual shingles of various sizes and shapes, tailored to different roofing needs and design preferences.

Adding Sealant

A strip of adhesive sealant is applied to the shingles to ensure they stick together once installed. This sealant enhances wind resistance and helps maintain a watertight seal, further protecting the home from the elements.

Packaging

Finally, the shingles are bundled, packaged, and prepared for shipment. Proper packaging ensures they are ready for transportation and easy to handle during installation.
