The average lifespan of a roof usually ranges from 25 to 50 years. However, the life expectancy of a roof ultimately depends on quality, durability and the type of material chosen. With this in mind, you can expect the average lifespan of an asphalt shingle roof to be about 22 to 25 years. While it's good to calculate the length of your roof, there are several factors that ultimately determine the lifespan.
A breakdown of the 5 most common roof types, how long each roof type lasts, and the signs to look for when a roof needs to be replaced. Since 1990, the Bill Ragan Roofing team has provided high-quality roof replacements to homeowners in Nashville and surrounding areas of Central Tennessee. A metal roof can last between 40 and 70 years with guarantees ranging from 20 years to a lifetime, depending on the type of metal and the design of the roof. Clay tile roofs won't last as long in colder climates, as constant freezing and thawing can easily damage the roof tiles.
That's probably a good enough reason to replace the roof, but there are other situations where you might want to take a close look at the way your roof is located. Cedar roofs are also capable of withstanding winds of up to 245 miles per hour, making them a popular type of roofing material in coastal homes. For example, a roof installed over an existing layer of shingles should generally be replaced after no more than 20 years. As long as it is properly installed and properly tiled, it will be the last roof you place in your house.
To ensure that your clay tile roof lasts as long as possible, it's important to clean it properly. A metal roof system with vertical joints consists of a series of metal panels that are joined together at the joints or are mechanically sealed. But as long as you hire a good roofing contractor and invest in quality materials, you should get as close as possible to the maximum lifespan of your roof. The installation of a new roof is also an opportunity to check the condition of the subroof, repair any hidden damage and re-seal peaks, valleys, ventilation grilles and other elements.
With a trusted roofer on your side, you're sure to have a durable roof that will protect you for many years to come. So, actually, you'll want to start thinking about a new roof before yours reaches the upper limits of these ranges.
