Whether you’re buying a new home or you’re planning on staying put in your current house, you probably have an idea of the condition of your roof. But, it can be hard for homeowners to gauge exactly when they should get a roof replacement.
This article discusses 4 different types of roofs, how long each roof type lasts, and what signs to look out for when your roof needs to be replaced.
How Long Does A Roof Last?
One of the key factors that determine if you need a new roof is its age. Now, we all know roofs don’t last forever, but homeowners may be asking themselves: how long does a roof last?
Generally, you can expect your roof to last about 30 years. But, the actual lifespan of your roof depends on a number of things, including the type of roofing materials that were used as well as the environment.
What Factors Impact How Long Your Roof Lasts?
- Quality of the installation workmanship – A poor quality installation will shorten your roof’s lifespan.
- Environmental conditions – Exposure to high winds, extreme temperatures, and falling debris can decrease how long your roof lasts.
- The quality of materials used – Cheaper materials won’t cost as much upfront but will have to be replaced more often than other expensive roofing materials.
- The type of roofing material used – Each roofing material has different durability, making them last longer or shorter in different conditions.
While there are several factors that impact how long your roof lasts, your roof’s lifespan most heavily depends on the materials used. Let’s take a closer look at the various roof types and how long each of them lasts.
Different roof types and how long they last
Asphalt shingles are the most common roofing material in the United States because they are affordable, durable, and include warranties of up to 25 years. Made of fiberglass and asphalt sealant, asphalt shingles can effectively protect your roof structure from snow, wind, rain, and harsh UV rays.
Most asphalt shingle roofs will last between 15 and 30 years. However, this can vary based on the climate and weather conditions of where you live. For example, asphalt shingles won’t last as long in Colorado, because the dramatic temperature changes will cause the shingles to crack.
A metal roof can last anywhere between 40 and 70 years with warranties from 20 years to a lifetime, depending on the type of metal and the design of the roof. Metal roofs made of premium metals like copper and zinc can sometimes last for over 100 years!
Signs you need a metal roof replacement: Widespread rust, discoloration, roof leak damage, water staining in the attic, and/or mold.
Wood Shakes And Shingles
Usually, a wooden shingle roof lasts for about 30 years with warranties that run up to 30 years. In order for wood shingles and shake roofs to last, however, you need to perform regular maintenance. Wooden roof upkeep includes yearly cleanings, as well as repainting or staining every 5 years.
The type of wood that you use will also determine how long the roof will last. Cedar shakes, for example, last longer than other types of wooden shingles because cedar is rot and insect-resistant. Cedar shakes are also able to withstand winds up to 245 miles per hour, which makes them a popular type of roofing material for coastal homes.
Signs you need a wooden roof replacement: Splitting shingles, rotting shingles, pest damage, mold, and/or algae growth.
Clay Tile Roof
Clay tile roofs are extremely durable and can last anywhere between 50 to 100 years, and manufacturers offer warranties anywhere from 30 years to a lifetime! The life expectancy of clay tile roofs is so long because tiles are weather, rot, and fire-resistant.
To ensure that your clay tile roof lasts as long as possible, it’s important to properly clean your roof. If a clay tile roof isn’t regularly cleaned, algae, moss, and mold can accumulate. Moss is the most dangerous, as its roots can penetrate the tiles, ultimately causing roof leaks.
Clay tile roofs won’t last as long in colder climates, as constant freezing and thawing can easily damage the tiles. However, you can have your clay tiles sealed to help prevent cold weather impacts.
Signs you need a clay tile roof replacement: Cracked tiles, chipped tiles, pieces of tile in gutters, roof leaks, and/or water staining in the attic.
