Factors to Consider When Selecting Shingles
Several factors should be weighed when choosing asphalt shingles. Durability, aesthetic appeal, and warranty coverage are all paramount considerations. The climate in your region will significantly impact the shingle’s lifespan and performance. For example, areas prone to high winds require shingles with superior wind resistance, while areas with heavy snowfall need shingles capable of withstanding significant weight. The style of your home should also be considered to ensure the shingles complement the overall architecture. Finally, the warranty offered by the manufacturer provides a measure of assurance regarding the shingle’s expected lifespan and the manufacturer’s confidence in their product.
Key Characteristics Contributing to Shingle Longevity and Weather Resistance
The longevity and weather resistance of asphalt shingles are influenced by several key characteristics. The quality of the asphalt used in the shingle’s construction directly affects its durability and flexibility. A higher-quality asphalt will be more resistant to cracking and degradation over time. The fiberglass mat used as a base provides structural integrity and helps the shingle withstand wind uplift. The mineral granules on the shingle’s surface provide protection from UV radiation, which is a major cause of shingle deterioration. A thicker shingle generally offers better protection and a longer lifespan. Finally, the shingle’s design, particularly the interlocking features in architectural shingles, contributes to wind resistance and overall durability. For example, shingles with a higher wind resistance rating (often specified by the manufacturer) are better suited for areas prone to strong winds, like coastal regions. A real-life example would be comparing shingles with a Class 4 wind rating (higher resistance) to those with a Class 3 rating (lower resistance) in a hurricane-prone area; the Class 4 shingles would be a much safer and longer-lasting choice.
