We all know that roofs don’t last forever, you might be asking yourself: how long does a roof last? A simple shingle roof can have a lifespan of 20 to 25 years, while an architectural shingle roof that can withstand harsh weather conditions may have a lifespan of 50 years. While specialty roofs, like slate or tile, may not need a replacement for decades.
In the end, It all still depends on the type of the roof, the quality, environmental condition, and workmanship.
- Roofing Materials – each roofing material has different durability, making its lifespan longer or shorter depending on certain conditions.
- Quality of the Materials – we all know that using cheap materials won’t cost much but will have to be replaced more often than going with expensive ones.
- Environmental Conditions – having extreme temperatures, high winds, falling debris in your area can affect how long your roof will last.
- Workmanship – a poor quality installation shortens the roof’s lifespan.
While many types of roofs last longer than 15 years, while others can hold up well for 30 to 50 years or much longer than that, barring a serious storm, or a large fallen tree. Most roofing materials will last as much, but the actual lifespan of a roof still depends on the factors such as your area and the type of roof you have.
What are the factors that influence a roof’s lifespan?
- Materials – good quality materials can make a big difference when it comes to your roof’s lifespan. Most houses are topped with asphalt shingles because they are affordable, good-looking, and get the job done, but there are other options you can consider for your roof that will last for years to come.
- Installation – there are specific installation requirements for certain types of roof products that will allow them to achieve their maximum durability. Choose a roof installer who knows the product they are using, your area, and if what roof design you have.
- Ventilation – a well-vented attic can add more years from one roof placement to the next. A well-vented roof stays cool, preventing snow melt and ice damming in the winter. It also keeps your attic from getting moist and warm, which can make your roof rot from the inside out.
- Underlayment – roof underlayment is a waterproof material that is installed over your roof. It offers another layer of protection against rain, snow, and ice. Underlayment may add more years to your roof’s lifespan.
The key to having a long-lasting roof is to have regular roof maintenance and inspections performed by professional roofing company. By having to identify the issues early on and having them repaired, you can have your roof’s lifespan extended with these home improvements.
While several factors affect how long your roof’s lifespan is, it still depends on the materials used. Here are a few roof types and how long each of them lasts in certain conditions.
- Asphalt Shingles – is the most common roofing material because they are affordable, durable and warranties of up to an average of 25 years. They are made of fiberglass and asphalt sealant. Asphalt shingles will protect your roof from rain, wind, snow, and harsh UV rays. As long as they have been installed well, and aren’t negatively affected by heavy storms, asphalt shingle roofs can last between 15 and 30 years.
- Wood Shingles – can last up to 30 years when they are properly maintained, but they do require more maintenance compared to other types of roofing. Wood shingles are usually made of cedar because it is more resistant to rotting and insects compared to other types of wood. Cedar shakes are also a popular type of roofing material for coastal homes as they can withstand winds up to 245 miles per hour.
- Metal Roofs – are growing in popularity, largely due to their lifespan and durability. Metal roofs can last up to 70 years, depending on the type of metal and the design of the roof so you don’t need to worry about a roof replacement, although the installation and cost of the roof can vary depending on the quality and type of metal used.
- Clay Tiles – are extremely durable and can last anywhere between half a century or longer, and most of the time a century itself, but they can be very expensive. The lifespan of clay tiles roof is so long as they are weather, rot, and fire-resistant. To make sure that your clay tile roof will last as long as possible, it’s important to properly clean your roof. If it isn’t cleaned regularly, algae, moss, and mold can accumulate making moss the most dangerous of them all, as its roots can penetrate the tiles, which will ultimately cause roof leaks. Clay tiles won’t last long in colder climates, as constant freezing and thawing can damage the tiles easily. However, you can have your clay tiles sealed to help prevent the impact of cold weather on them.
