Benefits of Corrugated Roofing
Taking into account that a galvanized roof won't rust, and that a corrugated aluminum roof or corrugated steel roof will last for up to 100 years, there are not many downsides to owning this type of roofing.
Other benefits include resistance to rot and lack of vulnerability to insects such as termites. Most of these roofs are also treated with chemicals that prevent the growth of algae. In communities that are prone to wildfires, metal roots can provide a safe haven because of their noncombustible properties and Class A fire ratings.
Finally, their lightweight nature lightens the load on installation and underlying building structures. All of these properties lend themselves to the idea that corrugated metal roofing is as close to a perfect roofing material as there is. The value that comes with the durability, and the flexibility that comes with the ability to change its color and appearance, along with the quality that comes with all of its additional desirable properties, makes corrugated roofing one of the best values for your money.
The biggest downside to corrugated roofing before the advance of galvanized technology was the rust. Many homeowners and commercial building owners can't be blamed for thinking this, because in older buildings that used corrugated roofing, the rust can easily be seen. However, as mentioned earlier, manufacturers have used current technology to get rid of rust and corrosion problems, thus increasing the demand for the product. Now, the modern corrugated roofing sheets not only have rust resistant properties, but appeal to the aesthetic look that builders and owners are looking for.
There are, however, a few issues that you might want to be aware of. Denting in the corrugated sheet metal is an issue which is hard to stay away from. Besides the occasional bumping and bruising, hailstorms have been known to cause dents in corrugated metal roofs.
The expense of installation, while offset by the low cost of maintenance work required, is also a barrier for some people looking into corrugated metal roofing. If you are not convinced that noise is a nonissue, you can always make sure that a layer of insulation lies underneath the metal sheet during installation. Like all roofs, time will produce scratches and chipping. If a layer of paint is applied on top of the metal, peeling and fading may also occur over time.
