Manufacturing Process of Rubberized Asphalt Shingles
Rubberized asphalt shingles represent an advancement in roofing technology, incorporating polymers into the traditional asphalt shingle manufacturing process to enhance durability and performance. This improved composition leads to shingles that are more resistant to cracking, weathering, and granule loss, extending the lifespan of the roof. The manufacturing process itself involves several key steps, each contributing to the final product’s quality and characteristics.
Polymer Selection and Incorporation
The choice of polymer significantly influences the final properties of the rubberized asphalt shingle. Several types of polymers are commonly used, each offering unique advantages. Styrene-butadiene-styrene (SBS) modified asphalt is a prevalent choice, known for its excellent flexibility and resistance to cracking at low temperatures. Atactic polypropylene (APP) is another common option, providing superior resistance to high temperatures and UV degradation. The specific polymer and its concentration are carefully selected based on the desired performance characteristics and the target climate conditions. The polymers are typically blended with the asphalt base during the manufacturing process, improving the asphalt’s elasticity and overall durability. This blending process requires precise control of temperature and mixing to ensure uniform distribution of the polymer throughout the asphalt.
Manufacturing Steps
The manufacturing process begins with the preparation of the asphalt base. This involves heating and mixing the asphalt with the chosen polymer. Once the polymer is thoroughly dispersed, the mixture is applied to a fiberglass mat, which provides structural support to the shingle. Granules, typically made of ceramic or slate, are then applied to the top surface of the asphalt-polymer mixture to provide color, UV protection, and enhance granule adhesion. These granules are carefully selected for their size, shape, and color consistency. After the granules are applied, the shingles are cut to their final size and shape, often using automated machinery. Finally, the shingles undergo a curing process to allow the asphalt and polymer to solidify and bond to the fiberglass mat and granules. This ensures the shingle’s structural integrity and weather resistance.
Comparison with Traditional Asphalt Shingle Manufacturing, Rubberized asphalt shingles
The manufacturing process of rubberized asphalt shingles differs from that of traditional asphalt shingles primarily in the incorporation of polymers. Traditional asphalt shingles utilize asphalt alone as the base material, without the added benefit of polymer modification. This difference results in significant variations in shingle properties. The addition of polymers requires an extra step in the manufacturing process, namely the blending of the polymer with the asphalt. This step adds to the overall manufacturing cost, but the resulting improved performance often justifies the higher expense. The curing process may also differ slightly due to the different properties of the polymer-modified asphalt.
Material Composition Comparison

Physical Properties and Durability
Rubberized asphalt shingles offer enhanced performance compared to traditional asphalt shingles due to the incorporation of polymers, typically styrene-butadiene-styrene (SBS) or other elastomers, into the asphalt binder. This modification significantly impacts several key physical properties, leading to improved durability and longevity.
The addition of rubber significantly improves the flexibility and tear resistance of the shingles. The elastomeric properties of the rubber allow the asphalt to stretch and bend more readily without cracking, particularly important in areas with fluctuating temperatures or high wind loads. This increased flexibility helps the shingles withstand thermal expansion and contraction, reducing the likelihood of cracking or fracturing during temperature swings. The improved tear resistance means the shingles are better able to withstand impacts from hail or other debris, further extending their lifespan.
Lifespan and Weathering Resistance Comparison
Rubberized asphalt shingles generally exhibit a significantly longer lifespan than standard asphalt shingles. While standard asphalt shingles typically last 15-20 years, rubberized shingles can last 25-30 years or even longer, depending on climate and installation quality. This extended lifespan is primarily attributed to the enhanced resistance to weathering degradation. The rubber modification improves the asphalt’s resistance to ultraviolet (UV) radiation, oxidation, and water damage. This leads to less cracking, fading, and granule loss over time, maintaining the shingle’s structural integrity and aesthetic appeal for a longer period. For example, in regions with harsh UV exposure like the southwestern United States, rubberized shingles have demonstrated superior performance compared to their standard counterparts, exhibiting minimal degradation even after prolonged sun exposure.
Temperature Extremes and Performance
Rubberized asphalt shingles demonstrate superior performance in extreme temperatures compared to standard asphalt shingles. The flexibility imparted by the rubber modification allows the shingles to withstand significant temperature fluctuations without cracking or becoming brittle. In hot climates, the rubber helps prevent the asphalt from becoming excessively soft and losing its shape. Conversely, in cold climates, the rubber prevents the asphalt from becoming overly brittle and fracturing under stress. This adaptability to temperature extremes ensures consistent performance and prolonged durability across a wider range of climatic conditions. Studies have shown that rubberized shingles maintain their flexibility and integrity even at temperatures well below freezing, unlike standard asphalt shingles which can become brittle and prone to cracking in such conditions.
