1. Introduction to Asphalt Shingles

Asphalt shingles, including the beautiful city, are one of the most widely used roofing materials in the United States. We have witnessed their exceptional popularity and have been a part of countless roofing projects using these durable and versatile shingles. Understanding the manufacturing process behind these shingles can help you make more informed decisions regarding your roofing needs.

2. Raw Materials: The Foundation of Asphalt Shingles

Here, we believe in using only the highest quality raw materials for all our roofing projects. The production of asphalt shingles begins with the careful selection of the following components:

2.1 Asphalt

Asphalt, a sticky and highly viscous black liquid derived from the distillation of crude oil, forms the base material for these shingles. For our roofing projects, we source premium-grade asphalt to ensure the longevity and performance of the shingles in our diverse climate.

2.2 Fiberglass Mat or Organic Felt

The next component is either a fiberglass mat or an organic felt. Here, we prefer using fiberglass mats due to their exceptional strength and dimensional stability, making them an ideal choice for varying weather conditions.

2.3 Ceramic Coating

A ceramic coating is applied during the manufacturing process to enhance the shingles’ resistance to abundant sunlight and other environmental elements. This coating protects the shingles and adds to their visual appeal.

3. The Manufacturing Process

3.1 Preparing the Asphalt Mix

We prioritize precision and quality at every stage of manufacturing. The process begins with the precise blending of asphalt, fillers, and stabilizers, ensuring the mix is well-suited for the specific roofing projects we undertake.

3.2 Mat Soaking

To create shingles with optimal strength and durability, the selected fiberglass mat undergoes careful soaking in the asphalt mixture. This meticulous process guarantees that each shingle is ready to withstand the challenges of San Diego’s climate.

3.3 Coating Application

Once the mat soaking is complete, the shingles receive a uniform ceramic granular coating. These granules are handpicked to ensure they complement the aesthetics of homes and commercial buildings while also offering reliable protection.

3.4 Cooling and Cutting

Following the coating process, the shingles are allowed to cool and solidify. Our skilled technicians then cut them into pieces with precision, making them ready for installation.
