A permanent metal roof is the way to go if you are needing a roof that never needs to be replaced. The choice of a metal roof goes a lot further than just being permanent. In fact, when you look into a permanent metal roof you can clearly see that the benefits outweigh the cost of having one installed.
It is obvious that a metal roof is going to protect you from rain, hail, snow, or sun. That is its job. The concern is whether or not you are going to be pelted with noise as the rain or hail hits the metal. The answer to that is no. No, you will not hear the noise anymore than you would with a regular roof. Most metal roofs are installed with a insulation barrier between it and you.
The next common concern is wind. With an asphalt roof you have to worry about shingles being peeled away in high winds. Not only is this not a problem, but in most cases your roof can withstand hurricane like winds. Even in a EF 1 or 2 tornado, it is highly likely your roof will be fine.
Earthquakes can be scary. The shaking of the ground can compromise the structure of your house. This compromising effect tend to make a heavy roof collapse onto the house. A permanent metal roof is not heavy and is a lot less likely to cause a collapse. If there is a collapse it is a lot easier to remove a metal roof because it does not require heavy machinery to be moved.
The overall cost of installing a permanent metal roof maybe a little higher than other roofing types. This is because it takes more training and specialized tools to install. However, time and costs can be reduced by installing it right over your existing roof. This also eliminates landfill by keeping your old roof out of landfills. The cost of installation is worth paying more for when you factor in the future savings you will have in maintaining your roof.
Should you have anymore questions you should contact a contractor that is local. They will have more information on how you can benefit from permanent roofs.
