The lifespan of your roof will vary depending on the materials used and your climate. Roof installation and maintenance may also affect how long your roof will last. Asphalt and wood shingles generally last anywhere between 15 and 25 years. Clay and concrete tile, slate, and metal roofing materials may last 50 years or longer. The climate conditions can alter these numbers dramatically. For instance, a dry climate can dry out asphalt shingles and cause them to become brittle or decay much faster. Roofs in cooler areas tend to last longer than those in hotter climates. Wood shingles may be affected by wetter climates, because moisture often leads to algae that deteriorates shingles and underlayment. Having your roof installed properly can prevent the major maintenance concerns. Inspecting your roof on regular basis can also help prevent costly repairs and other problems. Contact a roofing specialist for more information on the lifespan of your roof.
