Sheet metal roofing has gained a lot of popularity over the past few decades, a clear indication that home owners and builders are getting to learn more about its benefits. In fact, in the past 20 years, new types of sheet metal roofing materials have emerged—and these are totally different from the corrugated tin barn roofing materials that you see around and think of when metal is mentioned. But what is causing the recent interest in sheet metal roofing?
Longevity and Durability
One of the main features that homeowners consider when scouting for roofing materials is the durability of the material used. They want something that will last and will not need replacement after a few years. Interestingly, sheet metal roofs have been proven to last between 40 to 70 years depending on the material the metal has been fabricated from. Its lifespan beats the traditional asphalt roofing which lasts for approximately 10 to 20 years. Sheet metal roofs are also resilient and can withstand strong winds, making it a better roofing option for homeowners who do not want to keep doing repairs on their roofs.
Metal reflects the sun’s rays, which in turn reduces the amount of heat absorbed into the house during the day. This implies that you can avoid using the air-conditioning system during the day if not necessary to cut on energy costs. Again, during installation, there is a space left between the metal and the roof deck which can also act as a good heat insulator.
Minimal Roof Pitch/Slope
Roof pitch or the slope of the roof is often used to establish the type and amount of material that can be used on a particular roof. Sheet metal roofing can be installed on a roof that has a gentle slope/pitch and it would not have any leaks. Generally, the minimum roof pitch is approximately 3-in-12 (a rise of 3 inches for every one horizontal foot). Besides being hard and slippery, sheet metal fabrication companies design metal roofs in a way that they interlock, making them more impermeable to rain and snow.
Sheet metal roofing is lightweight—weighs 50 to 150 pounds per square metre depending on the material used—making it easier and faster to install. In fact, you can install some types of metal roofing materials over an existing roof without having to tear down the roof or adding any additional structural support.
Sheet metal roofing is also non-combustible. Actually, they fall under class A fire rating—highly resistant. Classification of a roof also depends on the type of material used for support beneath the surface. Accordingly, metal roofs installed over highly combustible materials like wood are given a lower ratings—Class C ratings.
When the time for your roof replacement comes, consider metal roofing as a viable option. While other roofing options often diminish in value over time, metal roofs provide a plethora of benefits: durability and proven performance, energy efficiency, fire resistance, and ease of installation among other benefits.
