How Long Do Asphalt Shingle Roofs Last?

Factors Affecting Asphalt Roof Longevity

Asphalt roof shingles typically last 15 to 25 years, with manufacturer warranties that reflect this anticipated lifespan. Still, the longevity of your asphalt roof may vary depending on these factors:

• Material quality: Not all asphalt shingles are created equal. High-quality shingles are more durable, have better granule adhesion, and offer superior resistance against weathering. Invest in quality asphalt shingles to extend the life of your roof and reduce the need for repairs or premature replacement.
• Roof slope: The style of your roof affects how quickly it sheds water and debris. Steeper slopes encourage faster runoff, reducing the shingles’ exposure to moisture, while flat roofs can become soggy and wear out faster.
• Attic insulation and ventilation: Attic conditions greatly affect the lifespan of your asphalt roof, so adequate insulation and ventilation are crucial. Without these characteristics, heat and moisture can build up in the summer, and ice dams become more common in the winter, deteriorating your shingles more quickly.
• Installation quality: Proper installation is critical to the longevity of your asphalt roof. Hiring an inexperienced roofing company or attempting a DIY job could lead to shingle buckling, curling, or even premature failure, shortening your roof’s lifespan.
• Climate factors: Roofing installed in areas with high winds, heavy snowfall, or intense sun may not last as long as roofs in more mild climates. Choosing asphalt shingles designed to withstand the Pennsylvania weather helps extend the life of your roof.
• Shade vs. sun exposure: Asphalt shingles exposed to the unrelenting sun day in and day out tend to age faster due to UV radiation. On the other hand, roofs surrounded by shade trees may be more susceptible to algae growth and moisture damage.
• Upkeep: A neglected roof is bound to wear out faster than a properly maintained one. Cleaning the gutters, removing debris, and addressing minor repairs can help your asphalt shingles last longer.
