What Materials are Used for Making Composite Asphalt Shingles?

By October 16, 2023No Comments

If you’re wondering, “What materials are used for making composite asphalt shingles?” Let Louisiana Roof Crafters help you out. Roofing choices can be as diverse as they are complex. But there’s one that stands out for its durability, cost-effectiveness, and aesthetic appeal: composite asphalt shingles. These wonder tiles are so common on American roofs that you might be living under one right now without realizing it! So why is it important to understand what they are made of? Simply because knowing the components and the science behind your roof can give you a significant advantage in maintaining its health and longevity. 


But what exactly are these, and what makes them a reliable roofing material? 

What Are Composite Shingles?

Composite shingles are a blend of at least two different substances, coming together to create a roofing surface that is layered and excellent at shedding water. They form a perfect synergy, where each material compensates for the other’s shortcomings. For instance, if you have a shingle made entirely of fiberglass strands, it would be hardy, but not waterproof. On the other hand, a shingle made purely from asphalt would be waterproof but might be prone to impact damage.

The kingpin of composite shingles is arguably the fiberglass asphalt shingle. This roofing material brings together the strength of fiberglass and the waterproof properties of asphalt, resulting in a product that’s durable, cost-effective, and straightforward.

Fiberglass Asphalt Shingles: The Powerhouse of Composite Roofing

Among various roofing options, fiberglass asphalt shingles have earned a distinctive reputation. Why? They efficiently merge the robustness of fiberglass with the waterproof quality of asphalt. Let’s delve deeper into these elements:

The Backbone: Fiberglass Mat

At the core of every fiberglass asphalt shingle lies a mat woven from fiberglass strands. This mat serves as the backbone of the shingle, providing it with the necessary strength to resist impacts, cracking, and tearing. It’s like a suit of armor for the shingle, tough yet flexible.

The Waterproof Shield: Asphalt

Once the fiberglass mat is ready, it gets a generous coat of asphalt. This coating gives the shingle its waterproof characteristics and allows it to mold and conform to the shape of the shingles below it. It’s this snug fit and the waterproof nature of asphalt that play a pivotal role in keeping leaks at bay.

The Defensive Armor: Granules

The final layer that completes the shingle is made up of granules. These granules are usually derived from crushed stones such as granite, basalt, or volcanic rock. They form a resilient exterior that stands up to weather conditions and impacts, boosting the overall durability of the shingle. It’s like a protective shield, ensuring the shingle stays intact and functional for a long time.

So, the fiberglass asphalt shingles that you see on many roofs are not just pieces of material. They are well-crafted units, each layer playing a crucial role in providing your home with a durable, weather-resistant, and aesthetically pleasing roof.

The Legacy of Organic Composite Shingles

While fiberglass asphalt shingles now rule the roost, there was a time when organic composite shingles were a preferred choice for many homeowners. Production of these shingles ceased in 2006, but they were known for their remarkable resilience in cold temperatures, attributed to their dual asphalt layers and thicker mat.

Unlike their modern counterparts, organic shingles did not use fiberglass for the mat. Instead, they utilized recycled materials like cardboard, wood, and paper. These were then coated with asphalt and granules to provide water resistance and durability.

However, the inherent property of these shingles to absorb and leach volatiles – the essential compounds that lend strength, flexibility, and durability to the shingle – proved to be their downfall, especially in warmer climates.

Composite Asphalt Shingles – The Smarter Choice for Your Roof

Understanding the composition of composite asphalt shingles allows us to appreciate the thoughtfulness of their design – a design aimed at durability, water resistance, and cost-effectiveness. By uniting the structural strength of fiberglass, the water-resistant properties of asphalt, and the robustness of stone granules, these shingles present a roofing solution that stands tall against time and elements.
