How Long Should a Roof Last? The Basics Explained
Did you know some slate roofs can last over 200 years?
Before you get too excited, keep in mind that the average homeowner won’t get nearly that kind of mileage out of their roof. The lifespan of a roof depends on many factors, from the type of roofing materials you use to the climate and weather in your locale.
What should you know about the average roof lifespan? How long should a roof last in your area? And how do you know when it’s time to repair or replace your roof?
We’ll answer those questions and more, so keep reading!
Average Lifespan of a Roof
If you want a short, succinct answer, the average roof lifespan is between 20-30 years, although some roofing materials can last over 50 years.
Of course, these numbers are only averages. A severe winter or another natural disaster could significantly shorten the lifespan of a roof. It’s also vital to hire experienced contractors who use the best materials and installation methods.
Roof Lifespan: Factors to Consider
Let’s briefly consider the two main factors that impact how long your roof should last.
Over 75% of American homes use asphalt shingles for their roofs. They’re durable, affordable, and include long-term warranties. Depending on your locale, expect your asphalt shingle roof to last around 20-30 years.
Metal roofing has the longest lifespan, with most materials lasting between 40-70 years. Some premium materials, such as slate, copper, or zinc could last 100 years or longer.
Wooden shingles are popular in some areas and should last around 30 years with proper maintenance. It’s good to note that wooden shingles require annual cleanings, along with staining or repainting every 4-5 years.
Climate & Weather
It stands to reason that the more extreme the climate is, the more your roof’s lifespan could be affected.
Minnesota, for example, is subject to radical extremes in temperature, precipitation, and wind speed. We’ve seen temperatures as high as 115 degrees, as low as -60 degrees, and wind gusts over 120 miles per hour. In the wintertime, snowfall is often measured in feet — not inches.
What does all of this mean for your roof? The natural elements beat down on your house 24/7, and one major hailstorm or snowstorm could be enough to damage your roof.
To ensure you get the longest possible lifespan out of your roof, make sure to schedule regular roof inspections with qualified contractors. They can help you identify potential problems early, allowing you to make necessary repairs and keep your roof in good condition.
How Long Should a Roof Last? Now You Know
The exact answer to “How long should a roof last?” depends on a few factors. If your home was built with high-quality roofing materials and you keep up with a regular maintenance schedule, you should get at least a few decades out of your roof.
What if your roof has already been installed for a few decades? If you think your roof is nearing the end of its lifespan, it’s best to get a professional inspection to see where you stand.
