Metal roofs are great for the protection of your home. But with great protection, it also generates a significant amount of sound. No one wants to hear an unnecessary sound, especially when it comes from their roof. But homeowners who have installed metal roofing have to bear with it. It’s impossible to completely eliminate the sound generated through these metal roofs, but there are ways to reduce it. In this blog, we’ll discuss some ways to reduce to sound produced by metal roofs.

ROOF FASTENERS

The sound of a metal roof is a normal thing. What we can check here are the roof fasteners. If they have become loosed or there are not enough fasteners, then the sound can get increasingly loud. You should have a frequent check on these fasteners. Because of the loose fasteners, there is more friction generated between the roofs and the walls, and friction within the 2 roofs also increases. Once the fasteners are fixed, you will notice a significant reduction in sound.

UNDERLAYMENT OF ROOFS

Underlayments to the metal roof act as a significant barrier to sound. Usually, the underlayment is an entangled nylon filament foam. This is installed between the sheathing and the metal roof. This way it helps in reducing the sound transmission. Adding the foam makes the roof energy efficient.

Another thing you can do is install the metal roofing over an existing asphalt shingle roof. By doing this, the existing asphalt shingle roof becomes the underlayment of the metal roof.

INSULATION & FINISHING OF CEILING

Adding a finished drywall ceiling can reduce the sound of a metal roof up to 100%. This will act as a physical barrier that will reduce the sound transmission in the interior space. The thicker the ceiling, the lesser the transmission of sound. Another thing you can do is add insulation to the attic space to mute the transmission of noise.

ROOF PROFILE

The shape of the metal roofing can impact how much it vibrates and thusly. what you hear from inside your home or business. Flat-seam roofs will be less noisy because they sit directly against one another with no extra material in between them. Standing seam type also has this simplicity but with more complex profiles, which make stiffness problems easier fixed – making these types better choices for large buildings. where sound travels distance quickly due to its higher frequencies being low pitched sounds such as those made by machines running almost constantly during assembly lines etcetera.
