With this in mind, you can expect the average lifespan of an asphalt shingle roof to be between 22 and 25 years. While it's good to calculate the lifespan of your roof, there are several factors that ultimately determine the lifespan. An average roof lasts 25 to 50 years, depending on the quality, durability, and type of roof material. You usually get what you pay for, so keep in mind that cheaper options will require be replaced sooner.
For example, metal roofs cost much more than asphalt roofs, but they last three times longer. The longevity of asphalt shingles depends almost entirely on where they were installed and whether they were installed correctly. Shingles found in colder parts of the United States lasts longer than in warmer climates. The average life expectancy of shingles, which is normally around 20 years, is about 14 years in warmer environments, such as the Southwest; while, in the northern and northeastern regions of the United States, asphalt shingles last between 19 and more than 20 years.
The average roof lasts about 20 years, depending on the type of material used and how well it is maintained. Metal, concrete and clay roofs are other durable options, with lifespans ranging from 40 to 100 years or more. Whether you want to know how long your current roof will last or if you're trying to find the right material to invest in, it's important to know the lifespan of a roof. The lifespan of a roof varies considerably depending on material, geography, climate and manufacturer specifications. Steckel says steeper sloped roofs, including gable, mansard, four-pitched and dormer roofs, generally have a longer lifespan.
For more than 30 years, the Bill Ragan Roofing team has been educating homeowners about all important aspects of roofs, including roof lifespan. However, I can at least give you an idea of the average lifespan of roofs that most homeowners have in their homes. David Steckel, former senior director of strategic partnerships at Thumbtack, says that the lifespan of roofs varies significantly depending on the material. Metal roofs with vertical joints, the most common type of residential metal roof, have a lifespan of 50 years and can withstand winds of more than 100 miles per hour. Please note that the entire lifespan indicated below depends on proper roof installation and adequate ventilation in the attic.
However, they can be valuable tools to help maintain and protect the roof, which can indirectly contribute to extending its lifespan. While there are several factors that influence the lifespan of the roof, the lifespan of the roof depends largely on whether quality materials were used. While it's hard to put an exact number on the lifespan of a slate roof, there's no reason why it shouldn't last around 75 years or even close to 100.
