True or False: The lifespan of roll roofing increases with the number of plys.

The statement is accurate. The lifespan of roll roofing does indeed increase with the number of plys. Roll roofing is typically made of asphalt-saturated felt or a similar material that can be layered to enhance durability. Each additional ply provides extra protection against weather elements, increases resistance to tearing, and helps with insulation.

When you have multiple plys, it creates a thicker barrier, which can reduce the risk of leaks and other forms of damage over time. Therefore, in general, as you add more plys to the roofing system, you can expect an extension of the roof's lifespan due to this increased strength and durability.

In contrast, the other options imply limitations or conditions that do not broadly apply to the fundamental nature of roll roofing materials and their expected performance over time with additional layers. While different materials or conditions can affect overall lifespan, the basic principle is that more plys generally lead to enhanced durability and longevity.
