Metal Roofing

Metal Roofing

Metal roofing has been around since the ancient Romans and was often used as a show of wealth or respect for a god when a temple was built. In the earliest days of metal roofing, copper was the most popular material because of its ability to resist the elements. The look of copper was considered as a sign of wealth in some parts of the Roman empire, which is why metal roofs were only used on temples and the homes of the affluent.

Since the ancient times, metal roofs have evolved and become a popular choice in many parts of the world. Before you decide to put use metal roofing, you should understand the many different aspects of metal roofs and the things that may need to be done to put a metal roof on your home.

Materials Used

A copper roof that was installed on a temple in the 1200's still survives to this day, which makes copper a pretty good choice for roofing materials. However, copper can be the target of opportunistic criminals who are looking to possibly trade in your roof for its scrap value.

Galvanized steel and aluminum roofs have also become popular, but galvanized steel can rust and rot over time. Aluminum can also rot, but it takes much longer for aluminum to show signs of aging.

Heat and Metal Roofs

One of the realities of metal is that it is a great conductor of heat. That means that your copper roof could cause your cooling costs to rise significantly if it is not installed properly. Professional roofers have techniques that they use which mingle metal roofs with the proper kind of insulation to prevent massive heat absorption, which is just one reason why it is imperative that you have a professional roofer install your metal roof.

Noise Amplification

If you have ever dropped a chestnut on a sheet of metal, then you are aware of just how well metal amplifies sound. Now try to imagine chestnuts falling from surrounding trees and crashing onto a metal roof. Not only chestnuts, but rain, branches and animals can also cause significant noise when they come into contact with a metal roof.

Professional installers have special insulation techniques they use to eliminate the sound amplification effects of a metal roof. It is a good idea to have your metal roof inspected at least once a year to make sure that these sound deadening materials are in place and doing their job properly.

Metal Roofs Make Great Re-Roofing Projects

One of the more common uses for metal roofs is as a re-roofing cover for asphalt shingles. Instead of paying to have the shingles removed, the homeowner can have a metal roof put over the top of the shingles. There are still special measures that need to be take for sound and heat issues, but this becomes a good way to put on a metal roof at a discounted cost.

Recycled Materials

Metal roofs have grown in popularity in part because of the focus on cleaning up and maintaining the environment. Galvanized metal roofing materials are often made from recycled metal and then coated with a protective chemical to make them durable against the elements. Utilizing recycled materials has allowed metal roofing manufacturers to lower their costs and make these kinds of roofs viable options all over the world.

Other Options for Materials

Along with copper, steel and aluminum, there is also a couple of other materials that are very popular with metal roofing. Tin has been a material that has been used for a very long time with roofing and it remains a popular material to this day.

One of the more unique metal roofing products is galvanized steel coated in special stones. The stones serve two purposes. First of all, these natural enhancements can create a unique look that would go with a Gothic or even rural design theme. The stones can also help break up the heat that steel roofing transfers and make the installation process easier.

Coated Metal Roofing

Some metal roofing products are coated with a special protective material that tends to wear off over time. It is common for homeowners to choose coated metal for their roofs because coated metal is less expensive when installed. But coated metal also needs to be re-coated once the protective layer wears off and that can become more expensive than utilizing a material that is designed to withstand the elements for many years.
