How Long do Roofs Last?

A roof is more than the top of your home – it’s an essential exterior component that helps protect your property. A new roof is a significant investment, so choosing the appropriate material and roofing contractor to install it is important. In addition, understanding the lifespan and maintenance requirements for the different roofing materials will help you make the right decision when it’s time for a roof replacement. In this article, our team discusses the projected lifespan for the most common types of roofs seen in the Charlotte area. We’ll also discuss other factors that can influence roof longevity and the importance of routine roof inspections and maintenance. Here’s a closer look:

Types of Roofs (and Expected Lifespans)

A roof’s lifespan depends on various factors, but perhaps the most important is the type of roof material you choose to install. In this section, we’ll take a closer look at the three most popular types of roofs we see in the Charlotte area and how long you can expect them to last:

Asphalt Shingle

Asphalt shingles are the most common roofing material in the Charlotte area and the United States, thanks to the material’s affordability, durability, and ease of installation. Shingles are designed for high performance in most severe weather conditions and can last up to 30 years when maintained properly. There are two types of asphalt shingles, three-tab and architectural. While often more affordable, three-tab shingles have shorter lifespans than their architectural counterparts.


Metal roofs are a growing trend throughout the Charlotte area, primarily due to their longevity and durability. Metal roofs are typically made of premium metals and can last for up to 70 years. In addition, their durability makes metal roofs an excellent choice for properties subject to inclement weather events. Certain metal roofing styles can even withstand wind speeds of more than 150 miles per hour.


Whether it’s clay tile or slate tile, tile roofs tend to be durable and long-lasting. When cared for and maintained properly, clay and slate tile roofs can offer a lifespan of over 100 years or more. This longevity is primarily because clay and slate won’t rust or rot. Tile roofs tend to weigh more than other types of roofing materials, so they may not be suitable for all properties. They also need to be cleaned regularly so moss and mold don’t accumulate.

Factors That Influence Roof Longevity

Beyond the type of material that’s installed on your property, various other factors can influence roof longevity. These include:


High winds, hail, freeze and thaw cycles, and temperature swings can all take a toll on the overall condition of a roof, regardless of the material you choose. Discuss options with a local roofing contractor if you aren’t sure what material to choose. Local contractors are familiar with seasonal trends for their area and can advise what roof type should last the longest in your area.

Quality of Installation

Hiring a reputable roofing contractor for your next roof installation project is imperative. Shoddy craftsmanship regularly causes more problems with your roof over its lifetime and will likely make premature roof replacement necessary. We recommend reading reviews and checking for accreditations from Better Business Bureau. Additionally, shingle manufacturers like Owens Corning maintain an exclusive network of licensed roofing contractors who meet rigorous quality and installation standards. Roofing contractors in these networks can offer superior warranty options, too! Check out Signature Exteriors on Owen Corning Platinum Preferred Contractor network by clicking here.

Quality of Roofing Materials

Speaking of shingle manufacturers, we recommend learning about the brands and products chosen for your roof replacement. Signature Exteriors recommends materials by the industry’s top manufacturers, including Owens Corning, Certainteed, GAF, IKO, and Tamko.

The Importance of Routine Maintenance

Last, but not least – we think it’s crucial we discuss routine repairs and maintenance. Scheduling annual roof inspections and performing prompt repairs if your roof is damaged will extend the longevity of your roof. This becomes especially important for older roofs that may be reaching the end of their lifespan or after a severe weather event like hail or lightning. High winds and inclement weather can damage shingles and cause leaks and other issues. We encourage all property owners to schedule routine inspections – especially on older roofs – so that any problems or roofing damage can be addressed and repaired. These inspections can also help you determine how long your existing roof has until it will need to be replaced.
