by ActionLocal Jun 9, 2019
When you are building a new home, choosing the roof is one of the biggest decisions you have to make. It is not as simple as you think it is. You might have heard people saying that a metal roof is the best option you can choose, but the type of roof that will fit the structure and design of the building is not always the same.
Metal roofing is becoming a popular trend all over the world. It is durable, low maintenance and the cost is also relative. It is considered as the best roofing material for homes and commercial buildings too. if you get to know some other things about metal roof, then you will also believe that it might be the best option for you.
1: You Won't Have to Replace the Roof Ever:
This might be one of the biggest reasons why people switched to metal roofs in the first place. Other roofing materials get damaged over time and they need to be replaced after every couple of years, but once you install the metal roofs, you won't need to buy another one for the rest of your life. We agree that they can be a big one-time investment, but if you compare the one-time expense with a lifetime of saving, you will realize that it didn't cost much. The metal roofs will last more than 50 years or so once they are installed.
2: Not Just a Novelty:
There was a time, when metal roofs were considered a novelty. Hence the high-end, architect-designed homes were the ones, where it was installed, but this is no longer true. Thanks to the increasing availability and advanced manufacturing processes, metal roofing can also be found in the conventional houses. Currently, about 15% of the world's roofing companies use metal roofing materials. The rate is increasing day by day and soon there will come a day, when most of the people would recognize the plus points of installing a metal roof in their homes.
3: Metal Roofs Can Be Installed Over Existing Roofs:
People think that replacing the shingles and tearing them off will create a lot of mess around the house, but according to the American Code, the metal roof can be installed without tearing off the existing roof. The removal of shingles is considered as the perfect route, it can be costly too.
The main reason it is avoided, is because of the potential risk of trapped water vapor. If the water is trapped between the old and new roofing, the moisture build-up will harm both the materials and they will begin to rot, but metal roofs even have a solution for this problem, i.e. vented roofs. Before you install the roof directly over the shingles, consult local building codes as some jurisdictions mention a full tear off before a new roof is installed.
4: Metal Roofs Are Not Noisy:
It is a very common misconception, that metal roofs are noisier than asphalt roofing and similar materials. So, during rain or hail, they will disturb you more. In reality, when the metal roof is properly installed, they will not result in a considerable difference. For better results, the metal roof is laid over a solid substrate which acts as an insulation material. Therefore, you will have a sound barrier so that you won't experience any increase in the sound levels.
5: Metal Roofing Is Safe From Lightning:
Half knowledge can be very dangerous and this myth proves it. People think that as metals are a good conductor of electricity, they attract lightning. After all, lightning is just a form of electricity, but is not true at all? Metal roofing doesn't increase the risk of a lightning strike on your house. Instead, if ever lighting strike your house, it will protect you.
Using the wood shakes or shingles seems like a good deal but they are combustible. But metal roofs are less combustible than the conventional roofing materials. The simple science involved in this is also understandable if you focus on it. Lightning seeks a path to ground which is why trees and telephone poles tend to attract lightning. Metal Roofs are isolated structures which have no direct path to ground. So, there is no reason why a metal roof will do more harm than good.
6: Metal Roofing is Impervious to Fire, Rot, and Insect Damage:
Metal roofs are safer than you realize, and it is the main reason for their popularity. They are virtually fireproof, rot proof and safe from various types of issues too. Metal roofing isn't affected by mildew or rot. Insects or pest infestation can't reach the metal. And since the metal conducts heat quickly from the sun, snow will also slide off quickly from the roof.
7: Choose a Specialist:
As the metal roofs are accepted widely, don't think that everyone qualifies as the professional to install the roof. The install and repair work of metal roofs is more complicated than it sounds. Generally, they are only available through selected retailers. Therefore, the techniques for installation and repair also require special skills. If you are choosing the metal roofs for your house, call a specialist who can assure you that the work is done with proper care.
Among all other things, you will be glad to know that metal roofs are recyclable. When the time finally comes to replace the old metal roof, you can sell the old one to a metal recycling outlet. They can be recycled over and over again without losing the quality. As you can see, the metal roofs will never go to waste. As a cherry on the top, these roofs are also energy efficient. Therefore, you get all the benefits and none of the drawbacks with metal roofs.
