Tar Roof Shingle Composition
Tar roof shingles, also known as asphalt shingles, are a prevalent roofing material chosen for their affordability, ease of installation, and relatively long lifespan. Understanding their composition is key to appreciating their performance and longevity. This section details the typical components and manufacturing process of these common roofing shingles, along with a comparison of different asphalt types used in their production.
Asphalt shingles are primarily composed of a fiberglass mat, asphalt, and mineral granules. The fiberglass mat acts as a reinforcing base, providing structural integrity to the shingle. Asphalt, a petroleum-based product, is the binder that holds the shingle together and provides waterproofing. Finally, mineral granules, typically made of crushed slate, ceramic, or other similar materials, are embedded on the shingle’s surface for UV protection and aesthetic appeal. These granules also contribute to the fire resistance of the shingle. Some higher-end shingles may incorporate additional components like polymer modifiers to enhance durability and flexibility.
Asphalt Shingle Manufacturing Process
The manufacturing process involves several key steps. First, a fiberglass mat is created through a process of weaving or felting fiberglass strands. This mat is then saturated with asphalt, ensuring complete impregnation for optimal strength and waterproofing. Following saturation, the asphalt-coated mat is then coated with additional asphalt, often a different type or formulation, to create a more durable and weather-resistant surface. Finally, the mineral granules are applied to the top surface while the asphalt is still hot and sticky, adhering firmly to the shingle. The shingles are then cooled and cut to their final size and shape before packaging and distribution.
Types of Asphalt Used in Asphalt Shingle Production
The type of asphalt used significantly impacts the shingle’s performance characteristics. Different asphalt types offer varying degrees of flexibility, durability, and resistance to weathering. Common types include oxidized asphalt, which is harder and more brittle but offers excellent resistance to weathering, and SBS (Styrene-Butadiene-Styrene) modified asphalt, which is more flexible and durable, especially in colder climates. The choice of asphalt depends on factors like the climate, the desired shingle lifespan, and the overall cost considerations.
Oxidized asphalt is often used in standard, budget-friendly shingles due to its lower cost. It provides adequate performance in many climates but may become brittle and crack more readily in extremely cold or hot conditions. In contrast, SBS-modified asphalt is typically found in higher-quality, more expensive shingles. Its superior flexibility and durability make it a better choice for regions with extreme temperature fluctuations or harsh weather conditions. The enhanced flexibility helps prevent cracking and ensures the shingle maintains its integrity over a longer period.
