What is the Life Expectancy of a Flat Roof?

The materials used to construct a flat roof have a major influence on its lifespan. A multi-layered roof made of waterproof material, hot tar and gravel can last for up to 20 years. Roofs that are composed of three to five layers of modified bitumen have a slightly shorter average lifespan, ranging from 10 to 15 years. With proper maintenance, flat roofs in residential buildings can last up to 50 years.

There are various types of flat roof materials, each with its own life expectancy. Homeowners often want to know the average lifespan they can expect from their flat roof. Here are the most common residential flat roof materials: EPDM, metal roofing, and modified bitumen. As experienced commercial roofers, one of the most frequent questions we hear is: “How long does a flat roof last?” The answer depends on the type of roof.
