Rubberized Asphalt Shingles: The Modern Roofing Solution
Choosing the right roofing material is a crucial decision for any homeowner. The roof protects your home from the elements, contributes to its aesthetic appeal, and can significantly impact its value. While traditional asphalt shingles have been a long-standing choice, rubberized asphalt shingles are rapidly gaining popularity as a more durable, eco-friendly, and high-performing alternative. This comprehensive guide will delve into the world of rubberized asphalt shingles, exploring their composition, benefits, drawbacks, cost considerations, installation process, and comparisons to other roofing materials.
What are Rubberized Asphalt Shingles?
Rubberized asphalt shingles, also known as modified asphalt shingles, are a type of roofing material that incorporates rubber polymers into the asphalt mix. This modification significantly enhances the shingles’ properties, making them more flexible, durable, and resistant to damage. The two main types of rubberized asphalt shingles are SBS (Styrene-Butadiene-Styrene) modified and APP (Atactic Polypropylene) modified. SBS is generally known for its rubber-like elasticity and low-temperature performance, while APP offers enhanced UV resistance and high-temperature stability. The base of the shingle is still typically asphalt, but the rubber polymers act as a strengthening and modifying agent, improving its overall performance.
The Composition of Rubberized Asphalt Shingles
Understanding the composition of rubberized asphalt shingles is key to appreciating their superior qualities. A typical rubberized asphalt shingle consists of several layers, each contributing to its overall functionality:
- Asphalt Core: The core of the shingle is made of asphalt, a petroleum-based product that provides waterproofing. In rubberized shingles, this asphalt is mixed with rubber polymers (SBS or APP) to enhance its flexibility and durability. The amount of rubber polymer added can vary between manufacturers and product lines.
- Reinforcement Mat: A fiberglass or organic mat is embedded within the asphalt core to provide strength and tear resistance. Fiberglass mats are more common in modern shingles due to their superior fire resistance and longevity. Organic mats, while once prevalent, are less resistant to moisture and decay.
- Granule Layer: The exposed surface of the shingle is covered with a layer of mineral granules. These granules serve multiple purposes: they protect the asphalt core from UV degradation, provide color and aesthetic appeal, and offer fire resistance. The granules are typically ceramic-coated for enhanced durability and color retention.
- Sealant Strips: Most asphalt shingles, including rubberized ones, feature sealant strips that are activated by the sun’s heat. These strips bond the shingles together, creating a watertight seal and preventing wind uplift. The effectiveness of the sealant is crucial for the long-term performance of the roof.
- Back Surfacing: The underside of the shingle is usually coated with a fine mineral surfacing material to prevent the shingles from sticking together during storage and transportation.
