Which of the following roofing materials should last the longest?

Slate is known for its exceptional durability and longevity as a roofing material. When properly installed and maintained, slate roofs can last over 100 years, making them an excellent choice for those looking for a long-lasting roofing solution. The natural stone composition of slate provides superior resilience against various weather conditions, including heavy rain, extreme temperatures, and high winds.

In contrast, the other options generally have shorter lifespans. Wood shakes can last around 30 to 40 years but are susceptible to rot and insect damage. Asphalt three-tab shingles typically last about 15 to 30 years, depending on the quality and environmental conditions. Rolled roofing is often used for low-slope roofs and generally has a lifespan of about 10 to 20 years. Thus, slate stands out distinctly as the option with the longest expected lifespan among common roofing materials.
