What are Rubberized Asphalt Shingles?
Rubberized asphalt shingles are a type of roofing shingle that incorporates modified asphalt with polymers, most commonly styrene-butadiene-styrene (SBS) rubber. This modification enhances the shingle’s durability and performance compared to standard asphalt shingles. They offer a longer lifespan, improved resistance to extreme temperatures, and increased flexibility.
Rubberized Asphalt Shingle Manufacturing
The manufacturing process begins with the preparation of the asphalt base. Standard asphalt is blended with SBS rubber, which is a synthetic elastomer. This mixture is then heated and thoroughly mixed to ensure uniform distribution of the rubber modifier. The resulting modified asphalt is more flexible and resistant to cracking than unmodified asphalt. This modified asphalt is then applied to a fiberglass mat, which provides structural support. The shingle’s surface is then coated with mineral granules, which provide color, UV protection, and weather resistance. Finally, the shingles are cut to their final size and packaged for distribution. The precise process can vary slightly between manufacturers, but the core elements remain consistent.
Rubberized Asphalt Shingle Composition
Rubberized asphalt shingles consist primarily of three components: modified asphalt, fiberglass mat, and mineral granules. The modified asphalt, the key differentiator, is a blend of standard asphalt and SBS rubber. The SBS rubber acts as a modifier, enhancing the asphalt’s flexibility, elasticity, and resistance to temperature extremes. The fiberglass mat provides structural integrity and support to the shingle, preventing sagging and tearing. The mineral granules, typically made of slate, ceramic, or other similar materials, protect the shingle from UV degradation, weathering, and impact damage, and also provide aesthetic appeal. The proportion of each component influences the overall properties of the final shingle.
Physical Properties Comparison: Rubberized vs. Standard Asphalt Shingles
Rubberized asphalt shingles exhibit superior physical properties compared to their standard counterparts. Standard asphalt shingles are more prone to cracking and damage from temperature fluctuations and weathering due to the asphalt’s inherent brittleness. Rubberized shingles, however, possess enhanced flexibility and elasticity thanks to the rubber modifier. This improved flexibility allows them to better withstand thermal expansion and contraction, reducing the risk of cracking and shingle failure. They also demonstrate superior resistance to wind uplift and impact damage. The enhanced durability translates to a longer lifespan and reduced maintenance needs over the shingle’s service life.
