Asphalt shingles are a popular choice for roofing in North America due to their affordability and durability—at least, they used to be. Over the last few decades, however, some homeowners have noticed that asphalt shingles are aging and deteriorating faster than expected. Various factors can contribute to this accelerated wear, including exposure to harsh weather, installation errors, and neglect in maintenance.
Understanding the Lifespan of Asphalt Shingles
On average, asphalt shingles are expected to last between 15 and 30 years. However, the actual lifespan can vary depending on the quality of the shingles, the skill of the installation, and the climate in the area. Higher-quality shingles generally have a longer lifespan, while cheaper alternatives may start showing signs of wear much sooner.
Weather: The Main Culprit in Shingle Deterioration
Exposure to the elements is one of the biggest reasons for asphalt shingles wearing out prematurely. Sunlight, rain, hail, snow, and wind all take their toll over time, leading to cracking, curling, or warping of the shingles. Extreme temperature swings, like the searing heat of summer or the freezing cold of winter, can cause the shingles to expand and contract, further weakening the material.
The Importance of Proper Installation
Improper installation is another major cause of shingle aging. If shingles are not installed with precision, they may fail to provide adequate protection against the elements. For instance, poorly sealed or improperly fastened shingles are more prone to wind damage or water leaks. A solid installation process is key to ensuring that the roof can withstand years of weathering.
Neglected Maintenance Can Accelerate Aging
Even the best shingles can age prematurely without regular maintenance. If roofs aren’t routinely inspected and cleaned, debris like leaves, branches, and dirt can pile up, trapping moisture against the surface of the shingles. This lingering moisture can lead to water damage, mold, and mildew. Similarly, clogged gutters can cause water to overflow and damage the roof, speeding up the deterioration process.
Steps to Extend the Life of Your Shingle Roof
To prevent premature aging and extend the life of your roof, proactive maintenance is essential. Regular inspections and cleaning can catch small issues before they develop into bigger problems. Choosing high-quality shingles and hiring an experienced, reputable contractor for installation also helps ensure that the roof lasts as long as possible.
Final Thoughts: Protecting Your Roof Investment
Although asphalt shingles remain a cost-effective roofing material, they are susceptible to early aging if not properly maintained or installed. By prioritizing regular upkeep and working with trustworthy roofing professionals, homeowners can protect their investment and enjoy a long-lasting roof.
A Note on Shingle Quality
One additional factor to consider is the quality of shingles from today’s manufacturers—a topic we’ll explore in more depth in a future article.
