Top 5 Reasons a Metal Roof Is Noisy

1. Insulate your ceiling

The denser the barrier between your roof covering and your attic (or top level), the less noise you’ll be hearing. One means in cutting down on the noise is to mount insulation. This is an action that is usually taken retroactively as it is not required when a roof is installed with the correct kind of roof underlayment.

If your metal roof is causing too much noise, then you might want to consider applying better sound deadening insulation in your attic or the top level ceiling. Check out my How to soundproof a ceiling article or keep on ready for more tips in hopes of soundproofing your metal roof.

If your attic is left uninsulated, then you should start there. Installing QuietRock noise reduction insulation or spray foam is a great place to begin. Both of these methods will add a physical barrier between the noisy roof and the interior of your home.

You should also install a resilient channel onto an existing finished ceiling. A resilient channel will leave an air gap between the insulation and the ceiling which will help concerning noise reduction.

2. Assure the Roof is Properly Fastened

If the roofers installed your metal roof incorrectly, then it is possible that you have fastener problems. The roof fasteners are what holds your roof in place tightly.

Have a look or contact someone that has experience regarding metal roofs and have them check if the roof fasteners are installed correctly. If the fasteners were incorrectly attached and are now loose, then this can cause the metal roof to move just enough to make noise in certain weather condition.

The roof will be extra noisy if it has fastener issues when raining causing noise to resonate throughout the house. In addition to inclement weather, a temperature change can also affect a metal roof that is improperly attached. During seasonal changes, the expansion and contraction of the roof will undoubtedly intensify the situation.

3. Proper Roofing Underlayment

Before mounting the metal roof, a proper roofing underlayment needs to be installed. Attaching an underlayment between the roofing sheathing system and the metal roof is an essential step regarding decreasing the noise that would otherwise come from the metal roof.
The most popular kinds of materials utilized for a roof underlayment are mats that are made from nylon filaments and also foam insulating panels.

This is an action that needs to be taken throughout the installation of the metal roof. If your roofing system is mounted without an appropriate roofing system underlayment, you will certainly experience the type of noise that tends to give metal roofs a bad name. However, with proper materials between the metal and you, there is no need to stress over having a metal roof.

4. Choose a Silent Steel Roofing Profile

The kind of steel roof you pick could influence the amount of noise that transfers throughout the house. Corrugated roof covering, which usually shakes more than level roofing, especially during inclement weather, could be a noisier option.

In hopes of keeping your roof as quiet as possible, you could take into consideration a flat or standing seam metal. These types of roofing hug the roof deck as well as general experience much less resonance and, as a result, much less noise, especially on those windy winter nights!

One thing to consider regarding a noisy roof is not only the shape of the metal but the quality of the steel. The stronger and more complex a metal roof quality is, the stiffer the roof material will be, and that will play a significant role as to how much the roof might vibrate.

While the shape of the metal versus a flat metal profile may have some impact on noise levels, it’s the stiffness, strength, and quality of the material that is especially influential on how noisy the roof will end up being.

5. Trust the Roofing Company

In this day and age, there is entirely no reason why a metal roof would be any louder than a conventional asphalt roof. If you chose a well-regarded roofing company that mostly specializes in steel roof, then you should not have a problem with noise, especially if they use high-quality steel.

After choosing a roofing company, I would suggest you call some references to previous roofing projects they recently completed. By speaking to homeowners that have a metal roof, it will give you a better idea as to what to expect regarding noise.

Metal Roof Noise When it Rains

As I stated above, a metal roof, if installed correctly and with high-quality material should not be any noisier than a conventional asphalt shingle roof.

Another thing to note is that during a heavy rainstorm a metal roof is much less prone to failure versus a regular roof. This goes for high wind, UV conditions and basically, any weather mother nature throws at them.

Metal roofs are not perfect, but they are more durable, stronger and energy efficient than what you would be used to in an asphalt roof during harsh stormy weather. Some of these roofs can even last up to 50 years. Now that might be a smart investment if you plan on owning the home for a long time.
