The roof above your head won’t last forever. Think about it: this material sits on top of your house, exposed to all the harsh elements of Michigan weather. In summer, you’ll have extreme heat and solar exposure. In winter, you’ll have heavy snow and blisteringly fast winds.
So the question on many homeowners’ minds is: ‘how long does a roof really last?’
Let’s dive into the factors that determine the life of your roof, plus what you can do to extend its lifespan.
How Long Does a New Roof Last?
The lifespan of a new roof depends on the roofing material used and how well it is maintained. On average, a new roof can last anywhere from 20 to 50 years.
Here is the average roof lifespan based on less common materials:
- Metal roof: 40 to 80 years
- Tile roof: 50 to 100 years
- Slate roof: 75 to 100+ years
- Wood shingles/cedar shake: 30 to 50 years
Keep in mind that your roof’s life expectancy depends on outside factors such as the type and quality of the materials, the installation process, and the local climate. You also need to consider accidental damage that can occur, like if a tree falls on your roof, heavy snow, or severe winds.
Of course, slate roofs, shake roofs, and tile roofs are not the norm here in Michigan. So let’s take a look at more typical roofing materials, starting with the ever-popular asphalt roof.
How Long Does an Asphalt Roof Last?
Most asphalt shingles have an average lifespan of 15 to 30 years depending on its durability, cost-effectiveness, and installation team. It’s also relatively low-maintenance and easy to care for, thanks to its fiberglass coating and organic mat base.
Asphalt shingles are topped with mineral granules for added protection against the harsh sun. They provide excellent resistance against harsh weather conditions, such as rain, wind, and UV radiation, making them a reliable choice for many homeowners.
But in our harsh Michigan climate, how long do asphalt shingles last?
In Michigan, an asphalt roof typically lasts between 20 to 30 years. The frequency of cold winters, heavy snow, and occasional intense summer heat may significantly raise or lower this number.
Keep in mind that the type of asphalt shingles also plays a role—higher-quality architectural shingles (usually meaning thicker) have a longer lifespan than thinner shingles. And if you invest in quality felt underlayment, ice and water shield, and flashing, you may extend your roof’s lifespan closer to 30 years.
Remember: the quality of your roof installation is more important than the materials used to complete the job. Even the best materials won’t last long if they aren’t installed correctly.

How Long Does a Metal Roof Last?
A metal roof is known for its impressive durability, typically lasting between 40 to 80 years, depending on the type of metal used and the quality of installation. Unlike asphalt roofing, which may need replacement after a few decades, metal roofs can withstand extreme weather conditions such as heavy snow, rain, and strong winds without losing their integrity.
The lifespan of a metal roof is influenced by factors like the material (steel, aluminum, copper, etc.), maintenance practices, and the local climate. In areas prone to harsh weather or salt exposure, such as coastal regions, corrosion-resistant coatings or higher-quality metals can extend the roof’s life.
How do you extend the life of your metal roof? By keeping up with regular maintenance tasks:
- Regular inspections and maintenance
- Cleaning debris
- Checking for damage
How Long Does a Shingle Roof Last?
The lifespan of a shingle roof largely depends on the material used.
Here’s what to expect from some of the most popular options:
- Asphalt shingles, the most popular choice, typically last between 15 to 30 years. However, this can vary depending on the quality of the shingles, the climate, and how well the roof is maintained.
- Architectural or laminated shingles tend to last longer than their three-tab counterparts. Most offer durability that can extend beyond 25 years.
- Standard three-tab shingles may only last around 15 to 20 years. Environmental factors like extreme weather, temperature fluctuations, and humidity can accelerate wear, reducing the roof’s lifespan.
Regular maintenance plays a crucial role in extending the life of a shingle roof. Cleaning gutters, checking for damage, and addressing issues like loose or missing shingles can help prevent leaks and other problems that might shorten the roof’s life.
So How Long Does a Roof Last?
The lifespan of a roof varies depending on the material used. Asphalt roofs typically last 15 to 30 years, while metal roofs can last 40 to 70 years.
Other roofing materials, like wood or slate, may last anywhere from 20 to 50 years.
Factors such as climate, maintenance, and the quality of installation can all impact how long a roof will last. Regular inspections and care can help extend its lifespan and ensure reliable protection.

FAQs Related To How Long Does A Roof Last
How often should you replace your roof?
You can expect to get around 20 to 25 years out of your 30 year shingle roof. Thicker shingles may last longer, but with harsher weather, it’s not always a guarantee. If your shingles start looking worn and brittle, it might be time to consider a roof replacement.
How do I know if my roof needs replacing?
If you notice leaks, curled or cracked shingles, worn granules, or exposed nails, it may be time to consider a roof replacement. Many roofing contractors provide estimates for free so you can get a better understanding of your roof’s survivability.
What is the number one cause of roof failure?
Poor quality installation. Shortcuts, laziness, and low-quality materials can dramatically reduce the lifespan of your roof. For this reason, it’s important to hire a professional installation team with excellent knowledge, experience, and workmanship.
