Are Metal Roofs Noisy?

By Cara Corridoni.

Spring rainstorms prompt questions from homeowners about life under a metal roof. Here is how to answer their concerns.

It’s a common debate as the peak rainy season approaches, especially among homeowners considering a re-roofing project this spring: Are metal roofs noisier than other roofing types?

Homeowners have posed the question frequently enough that the Metal Roofing Alliance (MRA), an industry group whose mission it is to help educate consumers about the many benefits of metal roofs, has posted the answers to their social media feeds.

“Homeowners typically fall into one of two camps,” says Renee Ramey, executive director of the MRA. “They either want to hear the patter of rain on their roof, or they don’t. A lot of people think the sound of rain is soothing and will help them sleep without the need for a fancy white noise machine. For others, they are worried the sound may be too disruptive.”

In either case, she believes the issue of noise can be a deciding factor for homeowners who are considering replacing a roof.

So which is it? Will a metal roof lull your customers into a nice sleep or keep them awake with its pinging?

The answer: Neither. A well-constructed metal roof simply won’t transmit any more sound than any other type of roof.

“People have the misconception because they have stood under metal shed roofs or similar structures and they, of course, sound loud. In those cases, you are standing right below the metal panel itself,” says CertainTeed Building Scientist Lucas Hamilton.

While metal can make a pinging or metallic ringing noise when struck, sound transmission depends on the roofing material as well as what lies below that material.

“A modern home would have roof decking, insulation and a layer of drywall or other ceiling material between homeowners and the roof,” says Hamilton. “Together they cut down significantly on the sound heard below.”

In addition to layers of sound-dampening buffers, today’s metal roofing material is often manufactured with formed or texturized patterns that help break up the impact of drops hitting the roof, leading to reduced sound.

The result is a roof that is no louder than other roofing types.

“If homeowners really want to hear the sound of rain, they are better off adding skylights. Which you also can do when installing a metal roof, by the way,” Ramey adds.

Mitigating Noise from Any Type of Roof

Follow these tips to stop roof noise from making its way down into your living spaces:

• Install the roof according to manufacturer’s recommendations. According to the MRA, too few fasteners, fasteners that are loose or are incorrectly placed can be an issue.
• Confirm there is proper insulation. Insulation is a known sound barrier.

Additionally, the shape of the roof is a factor when it comes to sound, no matter what material is used. A roof with a higher profile and more attic space tends to be quieter than a flat roof.

Considering all factors

Metal roofs offer additional benefits for those who reside in rainy regions. Thanks to tight seam construction, protective coatings and the natural water-shedding ability of metal, properly-installed metal roofs help prevent leaks and problems that can allow moisture to seep into a home’s interior.

“With any roof, the whole is greater than the sum of its parts,” says Ramey. “A quality metal roof that has been properly installed will deliver a lifetime of reliable protection, and for the vast majority of homeowners, that’s music to their ears.”
