Metal Roofing Features and Benefits – Part 1: Metal Roofing Durability and LongevityBy Stacy Mellete
Roofs and and their upkeep can translate to significant investments. Anyone who made such an investment wants to make sure that they make the most of what they spent. Nothing offers better proof of a good investment than durability and longevity, which result in outstanding life expectancy for a roofing system.
Commercial metal roofs fit the bill perfectly because they are among the most durable of roofing options available, with the added benefit of a low cost.
The Durability of Metal Roofing
Residential metal roofs can withstand winds with gusts of up to 140 miles per hour. They also won’t rot, decay, corrode or crack, and may even be impact-resistant depending on the metal they are made of. Today, you can find metal roofing materials treated to improve resistance against their worst enemy: rust. However, stainless steel roofing is also available, offering an option designed to double protection against rust, which makes it more durable and long-lasting.
Metal roofs are generally very easy to maintain as well, and can remain strong and reliable even if maintenance is only regular cleaning. Additionally, there are even more durable options available like stone-coated steel roofs and those made of alloys such as zincalume and galvalume.
The Longevity of Metal Roofing
Because of its durability, metal roofing can last a long period of time, remaining functional 40 to 70 years after installation, especially when high-quality materials are used and when routine maintenance is performed.
To compare, traditional asphalt roofing lasts an average of 25 years. While metal roofing is generally costlier than asphalt roofs, its longer life expectancy makes it a more cost-efficient choice.
How do metal roofs perform in terms of energy efficiency? We’ll talk more about that in Part 2 of this blog series, so stay tuned!
