So you want to get a metal roof, but you are worried about metal roof noise. Or maybe you already have a metal roof and you are tired of the racket. Well you need not worry, because this article will explain how you can have a metal roof without worrying about noise.

Metal roofs are growing increasingly popular. It is not hard to understand why. A well-built metal roof can last up to 50 years and requires less repair and maintenance than many other roofing options. In addition, a metal roof is considered to be a more environmentally friendly option and installing a metal roof on your home can significantly reduce your energy bills. As if that was not enough, metal roofing is just plain better looking. It has a modern, sleek appearance that outshines the old-fashioned asphalt shingles. So why doesn’t everyone have a metal roof? Because many people are worried about noise. But is a metal roof really noisier?

Depending on the materials used during installation, it is possible to experience excessive noise during rain and hail. However, this does not have to be the case. When installed correctly, your metal roof should be just as quiet as an asphalt shingle roof. Read on to learn how to ensure that your metal roof is not unnecessarily loud.

1. Insulate your ceiling

The denser the barrier between your roof and your interior space, the less noise you will hear. One way to cut down on the noise is to install insulation. This is a step that is generally taken retroactively as it is not necessary when a roof is installed with the proper type of roof underlayment.

If you have a noisy roof and want to do something about it, you could always install a layer of insulation. If there is an unfinished room or attic space in your house, consider adding the insulation there. Rigid foam insulation and spray foam insulation are two options that will greatly reduce your noise levels. They both create a physical barrier between the noise and you and absorb most of the noise before it has a chance to fill your home.

Roof fasteners hold your metal roof in place. If your roof was installed incorrectly, you may have fastener problems. If you do not have enough fasteners, if your fasteners are incorrectly placed, or if some of your fasteners are loose, this can cause your metal roof to react loudly to certain weather.

When rain or hail hits a roof with fastener issues, the roof may move, which causes the impact to be audible from inside the house. In addition, the expansion and contraction that happens during temperature changes can intensify the situation. Replacing or tightening loose fasteners, as well as adding additional fasteners, can help manage the noise.

3. Install a roof underlayment

When your metal roof is installed, a roof underlayment should be installed as well. Some of the most common types of materials used for a roof underlayment are mats that are made from nylon filaments and foam insulating panels. Installing an underlayment between the metal roofing and the roof sheathing is a key step to reducing metal roof noise.

This is a step that must be taken during the installation process. If your roof is installed without a proper roof underlayment, you will experience the kind of noise that causes people to think buying a metal roof is a bad idea. However, with proper materials between the metal and you, there is no reason to worry about noise.

The type of metal roof you choose can influence the amount of noise you hear. Corrugated roofing, which generally vibrates more than flat roofing, may be a noisier option. To keep your roof as quiet as possible, you can consider flat or standing seam metal. These types of roofing hug the roof deck and usually experience less vibration and, therefore, less noise.

That being said, the higher and more complex a roofing profile is, the stiffer the roofing material tends to be. While corrugated metal versus flat metal profiles may have some impact on noise levels, it is the stiffness of the material that is especially influential in how noisy the roof will be.
