Metal roofing is a long-lasting, durable, and energy-efficient option. However, homeowners often ask whether metal roofs are noisy when they're suggested as a housing solution.
Answer: Metal roofs could be noisy if constructed without a proper base, which would completely go against today's residential and commercial metal roofing standards.
The truth is, metal isn't noticeably noisier than other popular roofing options. Research from The Acoustic Group at the University of Luleå, Sweden, supports this. The research posits that people can't detect the subtle noise difference between a metal roof and an asphalt shingle roof.
Why Do Homeowners Think Metal Roofs Are Noisy?
The popular misconception stems from old metal roofing installation methods traditionally used for barns. These didn't include roof decks and insulation during installation to absorb sound and protect against leaks. Today, metal roofs are built much differently.
Firstly, your ceiling and attic are better insulated than buildings from generations ago. Roofers will also build a wooden roof deck above your top floor's ceiling to serve as a foundation for the metal material. Thirdly, your metal roofing material will likely vary from older options in thickness, surface texture, and coating, which can contribute to quieter roofing.
How Can I Make Sure My New Metal Roof Is Quiet?
There are various modern methods for dampening sound from your metal roof, including using thicker materials, installing additional layers between your ceiling and roof, and adding noise-reducing coatings after installation.
Choosing the Right Base
The first step to a quiet roof is installing strong roof decking. This wooden foundation creates more space between the roof and ceiling, dulling the noise.
If you or your family members are especially sensitive to noise, you can ask your roofing contractor about adding even more sound-absorbing material with wood fiber insulation boards between the decking and metal. You can even install metal roofing panels on top of existing shingles, which can help reduce noise further.
Choosing the Right Material
Thin metals like aluminum will be noisy because they're prone to vibration. Stronger, denser, and thicker metals, including noise-resistant materials like steel, copper, and zinc, will fare better.
Choosing the Right Top Finish
When sounds hit hard and flat surfaces, they reverberate, making them louder and longer lasting. One way to avoid this effect on a metal roof is to make the top layer textured so the surface that rain or hail hits isn't flat. Finishes like a rubberized or stone coating can be applied after installation to add texture and absorb sound, making your metal roof quieter.
Are You Considering a Metal Roof?
If you need a new roof, metal can be a great option. When properly maintained, metal roofs can last 50 or more years. They can even provide cost savings on monthly cooling expenses and make your home more energy-efficient since the reflective surface doesn't absorb as much heat.
