If you live in Moline, IL, there’s a good chance your roof is made of asphalt shingles. They’re one of the most common roofing materials in the U.S. But many homeowners don’t know how these shingles are made, or what makes them such a smart choice.
So let’s break it down in plain language. In this guide, you’ll learn how asphalt shingles are made, what asphalt shingles are made of, and why they’re a great option for your home in Moline.

What Are Asphalt Shingles Made Of?
Asphalt shingles may look simple, but they’re made of several strong materials that work together to protect your home.
Here’s a quick look at what asphalt shingles are made of.
1. The Base Mat
This is the bottom layer, which gives the shingle its shape and strength.
There are two types:
- Fiberglass base: Made of glass fibers. It’s light, strong, and fire-resistant.
- Organic base: Made from recycled paper or wood. It’s thicker and heavier, but it’s not used as much today.
2. The Asphalt Layer
This is the waterproof part of the shingle. Hot asphalt is added to the base mat to keep water, snow, and moisture out of your home.
3. The Mineral Granules
These tiny stone-like pieces are added to the top. They give shingles their color, but they do more than look nice.
They also:
- Block the sun’s UV rays
- Make shingles stronger
- Help protect your roof from fire
So, when people ask what are asphalt shingles made of, the answer is simple: a strong base, waterproof asphalt, and protective granules.
How Are Asphalt Shingles Made?
Now that you know what’s inside a shingle, let’s walk through how asphalt shingles are made.
Here’s a step-by-step look at the process.
Step 1: Making the Base Mat
If it’s a fiberglass base, tiny glass fibers are woven into a mat. If it’s organic, paper and wood are pressed into shape. This mat becomes the foundation of the shingle.
Step 2: Adding Asphalt
Next, the mat is coated with hot asphalt. This sticky material is spread over both sides. It keeps water out and helps hold the shingles together.
Step 3: Pressing on the Granules
While the asphalt is still warm, mineral granules are added to the top. They stick to the surface and protect the shingles from sun damage and harsh weather.
Step 4: Cooling and Cutting
Once the asphalt cools, the big sheet of material is cut into shingle shapes. Then they’re stacked into bundles and sent to roofing companies, including here in Moline, IL.
