Are you building a new house or planning to replace your current roof? Are you considering a metal roof over traditional asphalt shingles? If so, you probably have a few questions about metal roofing. One of those questions should be regarding how long the roof will last.
Metal roofing is highly durable and one of the longest-lasting materials available today. But how long does it last? Here’s everything you need to know about the longevity of metal roofs.
How Long Does a Metal Roof Last?
While the lifespan of a metal roof is typically between 40 and 75 years, it can last more than 100 years if properly installed and maintained. The type, thickness, and style of the material affect longevity. Here is the expected lifespan of different metal roofing materials:
- Steel roofing: 40 years
- Cooper roofing: 50-100 years
- Aluminum roofing: 50 years
- Zinc roofing: 60-100 years
- Tin roofing: 50 years
Compared to other roofing materials, metal costs has a higher upfront cost. However, its longevity and low maintenance requirements serve to offset the higher prices.
The longevity of a metal roof offers you long-term savings. Metal roofing is lightweight, which reduces installation costs and eliminates the need for structural enhancements due to load stress. Also, you won’t need to make frequent repairs to your roof.
The long lifespan of a metal roof could add to your home’s resale value.
What Makes Metal Roofing Last Longer?
There are several qualities that metal roofing has that gives it such an impressive life expectancy, including the following:
- Tough Components
Metal roofs are a complete system comprised of durable, high-performing components and not just sheets of metal. Metal roofing systems are more advanced than ever before. Their fasteners, clip systems, and other related components are designed with the latest technologies and materials to maximize the performance of your roof.
- Durability
Metal roofs have a long lifespan because they are tough and durable. They can sustain wind gusts of up to 140 mph without experiencing damage. They will not corrode or crack, and some types of metal are impact-resistant.
Metal roofs are fire-resistant and insect-resistant. They also allow rain and snow to slide off the surface quickly, minimizing the risk of water damage.
- Pest-Resistance
Metal roofs are resistant to termites, squirrels, and other pests, which can cause significant damage to wood shingles and asphalt shingles.
How Does the Lifespan of a Metal Roof Compare to Traditional Asphalt Shingles?
Asphalt shingles are the most popular roofing material because they are the most economical. However, that lower upfront cost is often outweighed by frequently required maintenance and a shorter lifespan.
Asphalt shingles have an expected lifespan of 10 to 20 years. Additionally, the roofing may need repairs and shingle replacement as the roof ages. Shingle roofs are also highly vulnerable to wind and hail damage.
A properly installed metal roof performs better than asphalt shingles in all climates. This performance can be attributed to the interlocking panels’ ability to resist lift and stay in position. Additionally, metal panels shed snow and water quickly, making them more resistant to leaks and ice dams that are common with traditional asphalt roofs.
A metal roof can last 50 to 60 years with minimal maintenance. Within those 60 years, asphalt shingles may need to be replaced two or three times. Roofing manufacturers typically offer a 50-year warranty on metal roofs.
When perfectly coordinated with siding and trim color palettes, the sharp, new modern appearance of a metal roof boosts curb appeal. Its life span increases the value of your home better than traditional asphalt shingle products available on the market.
What Are the Factors that Affect the Lifespan of Metal Roofing?
Different factors can affect the longevity of your metal roofing, including:
Installation
The most effective way to ensure your metal roof lasts as long as possible is to have it properly installed. Even simple installation errors, such as over-tightening fasteners, can result in damage and premature failure. Metal roofs are vulnerable to moisture damage and rust if not adequately sealed or ventilated.
Proper installation can help you make the most out of the lifespan of your roof.
Maintenance
While metal roofs are typically low maintenance, professional inspections at least twice a year help a metal roof last. A routine inspection can help you identify minor issues before they get out of hand. Also, you’ll want to clear debris from your roof and gutters and trim tree branches that may cause damage to your roof.
Weather
Weather conditions can affect how long your metal roof lasts. For instance, your metal roof may last longer if you live in an area with a mild climate. High-speed winds, heavy snowfalls, and other extreme conditions can cause faster wear and tear on your roof.
Aluminum and copper may not do well in colder climates. Steel may corrode in coastal environments. Choosing the correct type of metal roofing is essential and should be based on your area’s climate and typical weather conditions.
Gauge
The quality, durability, and longevity of metal roofing are also based on thickness. The thicker the gauge, the more durable the roof will be. Thicker metal (22 to 24 gauge) gives the rooftop more strength to resist wind uplift and handle snow load. Thinner metals (26 to 29 gauge) have reduced durability and longevity.
