Which roofing material typically lasts 30 years?

Built-up roofing (BUR) is a type of roofing material that is known for its durability and longevity, often lasting around 30 years or more under ideal conditions. This roofing system consists of multiple layers of asphalt, tar, or other substances, which create a strong and waterproof barrier. The layered construction helps protect against harsh weather conditions, UV exposure, and general wear and tear, contributing to its extended lifespan.

In contrast, while asphalt shingles, wood shakes, and single-ply membranes may have their own advantages, they typically do not match the lifespan of built-up roofs. Asphalt shingle roofs, especially the standard 3-tab variety, tend to last around 20 to 25 years. Wood shakes and shingles can last anywhere from 20 to 30 years but are often subject to deterioration from moisture, rot, and insects. Single-ply membrane roofing can vary in longevity depending on material and installation but often ranges from 15 to 30 years, depending on maintenance and environmental factors.

Thus, built-up roofing stands out for its capability to provide long-term reliability and performance, often reaching or exceeding the 30-year mark, making it a preferred choice for many commercial and residential applications.
