Composition shingles, commonly made from a mix of asphalt and fiberglass, typically have a lifespan that averages around 20 to 30 years, depending on factors such as climate, installation quality, and maintenance. The choice of 15 years may be a commonly referenced estimate for lower-quality composition shingles or for specific conditions that could shorten a shingle's life. However, it does not accurately reflect the typical lifespan of standard composition shingles, which often exceed this period under normal circumstances.

When considering roofing materials, it's important to note that proper installation and regular maintenance can extend their durability and performance. Therefore, while 15 years may be seen in some context, the more fitting answer regarding the overall expected longevity of composition shingles aligns better with the 20 to 30-year range.
