What is the average life expectancy of a 235 lb asphalt shingle?

  1. 10-15 years

  2. 15-20 years

  3. 25-30 years

  4. 30-35 years

The correct answer is: 15-20 years

The average life expectancy of a 235 lb asphalt shingle is indeed estimated to be between 15 and 20 years. This range takes into account various factors that can affect the longevity of asphalt shingles, such as environmental conditions, installation quality, and maintenance practices. Asphalt shingles generally consist of a base of fiberglass or organic mat which is coated with asphalt and granules. The weight of the shingles, in this case, 235 lbs, indicates a thicker, heavier shingle which often correlates with increased durability and resistance to weather elements. While weigh does contribute to longevity, the standard lifespan for asphalt shingles, especially the more common 3-tab variety, typically lies within the 15-20 year category. Other options provided suggest lifespans that exceed industry averages for standard asphalt shingles, which may lead to misconceptions about their durability. Therefore, recognizing the correct lifespan helps in setting realistic expectations for replacement and maintenance planning.
