Asphalt shingles are one of the most commonly used roofing materials in North America due to their affordability and durability...or so it used to be 20-30 years ago. However, despite their popularity, asphalt shingles can age and deteriorate relatively quickly depending on a variety of factors, including weather conditions, improper installation, and poor maintenance.

The average lifespan of asphalt shingles can vary greatly depending on the quality of the shingles, the installation process, and the local climate. In general, the lifespan of asphalt shingles ranges from 15 to 30 years, with higher-quality shingles lasting longer than lower-quality ones.

One of the primary factors that contribute to the aging and deterioration of asphalt shingles is exposure to the elements. Sunlight, rain, hail, snow, and wind can all cause damage to asphalt shingles over time, leading to cracking, warping, and curling. Extreme temperatures, such as those experienced during hot summers or cold winters, can also cause the shingles to expand and contract, further weakening the material.

Another factor that can contribute to the aging of asphalt shingles is improper installation. If the shingles are not installed correctly, they may not be able to withstand the elements as effectively as they should. For example, if the shingles are not properly sealed or are not attached securely to the roof deck, they may be more susceptible to wind damage or water intrusion.

Poor maintenance can also lead to the premature aging of asphalt shingles. If the roof is not regularly inspected and cleaned, debris such as leaves, twigs, and branches can accumulate on the surface of the shingles. Over time, this debris can hold moisture against the shingles, leading to water damage and mold growth. Additionally, if gutters are not cleaned regularly, water may overflow onto the roof and cause damage to the shingles.

In order to extend the lifespan of asphalt shingles and prevent premature aging and deterioration, it is important to take a proactive approach to maintenance. Regular inspections and cleaning can help identify and address any issues before they become more serious. Additionally, it is important to choose high-quality shingles and have them installed by a professional roofing contractor with a track record of quality work.

In conclusion, while asphalt shingles are a popular and cost-effective roofing material, they can age and deteriorate relatively quickly if not properly maintained or exposed to extreme weather conditions. By taking a proactive approach to maintenance and working with a reputable roofing contractor, homeowners can extend the lifespan of their asphalt shingles and protect their investment for many years to come.

Another major factor is shingle quality coming from todays manufacturers, but we'll get into that in another furture article!
