How Long Does Metal Roofing Last?

Metal roofing is a more common option for residential and commercial property owners. Metal roofing offers many advantages for individuals searching for a long-term roofing option because of its toughness, energy efficiency, and affordability. But how long is the lifespan of metal roofing? This article will examine the variables influencing metal roofing longevity, the typical lifespan of various metal roofing types, and strategies for extending metal roofing lifespan.

What is Metal Roofing

Metal roofing is a material constructed from steel, aluminum, copper, and zinc. Corrugated panels, standing seam, and shingles are among the designs and finishes available. Metal roofing is well-known for its strength and longevity, making it resistant to weather, fire, and pest damage. In addition, it has a longer lifespan than other roofing materials.

Factors that Affect the Lifespan of Metal Roofing

Metal roofing durability can be affected by the type of metal used, the thickness of the metal, the quality of the installation, and the environment in which it is installed. Let’s take a closer look at each of these components.

Type of Metal: The metal used in the roofing material can affect its lifespan. Steel is a common material because of its affordability and toughness, but it can rust and corrode with time. Stainless steel is even more durable and rust-resistant than galvanized steel, which has a zinc coating to prevent rust and corrosion. Due to its lightweight and resistance to rust, aluminum is another popular choice, albeit it might not be as durable as steel.
The thickness of Metal: The thickness of the metal used in the roofing material can also affect its lifespan. Thicker metal is generally more durable and less prone to denting or other types of damage. The thickness of metal is measured in gauge, with lower gauge numbers indicating thicker metal. For example, 22-gauge steel is thicker than 29-gauge steel.
Quality of Installation: The quality of the installation can also affect the lifespan of metal roofing. If the roofing is not installed correctly, it may be more prone to leaks, damage, and other problems. To guarantee that metal roofing is put correctly, it is critical to engage with professional metal roofing contractor.
Environment: The environment in which the metal roofing is installed can also affect its lifespan. For example, if the roofing is exposed to saltwater, it may rust and deteriorate more quickly. Similarly, if the roofing is built in a high-wind area, it may be more vulnerable to damage.

Average Lifespan of Metal Roofing

Metal roofing has an average lifespan that varies based on numerous aspects, such as the type of metal used, the thickness of the metal, and the environment in which it is erected. On the other hand, metal roofing typically outlasts other roofing materials, such as asphalt shingles.

Based on installation quality and metal thickness, steel roofing can endure between 40 and 70 years on average. Aluminum roofing spans 30-50 years, while copper and zinc roofs have a lifespan of 50-100 years.

Types of Metal Roofing and Their Durability

Several types of metal roofing are available, each with its own durability and lifespan. Let’s explore some of the most popular types of metal roofing and their durability.

Standing Seam Metal Roofing: Standing seam metal roofing comprises interlocking panels that run vertically along the roof’s surface. This type of roofing is known for its durability and resistance to water damage. Standing seam metal roofing can last between 30-50 years or more, depending on the installation’s quality and the metal’s thickness.
Corrugated Metal Roofing: Corrugated metal roofing comprises panels with a wavy pattern. This type of roofing is lightweight and easy to install, making it a popular choice for residential and commercial buildings. Corrugated metal roofing can last between 20-30 years, depending on the type of metal used and the quality of the installation.
Metal Shingle Roofing: Metal shingle roofing mimics traditional asphalt shingles’ looks but with metal’s longevity and durability. Metal shingle roofing is available in various finishes and styles and can last between 30-50 years or more, depending on the type of metal used and the quality of the installation.

Tips and Strategies to Extend the Lifespan of Your Metal Roofing

There are several tips and strategies that homeowners and business owners can use to extend the lifespan of their metal roofing. Let’s explore some of these tips.

Choose the Right Type of Metal: Choosing the correct type of metal for the roofing material can help to ensure its longevity. For example, stainless steel is more rust and corrosion-resistant than regular steel.
Install Proper Ventilation: Proper ventilation is essential for extending the lifespan of metal roofing. Ventilation helps to prevent moisture from building up on the roof, which can lead to rust and corrosion.
Use Professional Installation: Professional installation is also essential for ensuring the longevity of metal roofing. Hiring a professional roofing contractor with experience installing metal roofing can help ensure that the roofing is installed correctly and will last many years.
Invest in Coatings: Investing in metal roofing coatings can also help extend its lifespan. Coatings can help to protect the metal from the elements and prevent rust and corrosion.
Regular Maintenance: Regular maintenance, such as cleaning the roof and promptly addressing any metal roof repairs, can help extend the lifespan of metal roofing.

Metal roofing has a longer lifespan than other roofing materials like asphalt shingles. Metal roofing is available in a variety of styles and finishes. It can last between 20-50 years or more, depending on the type of metal used and the quality of the installation. To ensure the longevity of metal roofing, it is essential to choose the right type of metal, install proper ventilation, use professional installation, invest in coatings, and perform regular maintenance. By following these tips and strategies, homeowners and business owners can extend the lifespan of their metal roofing and save money over the long term.
