How to Soundproof a Metal Roof

Some homeowners may enjoy the enhanced sound of rain on metal material, like tin-coated stainless steel, and consider it a positive aspect rather than something that needs to be minimized. But for those of you that want to reduce sounds on your already-installed tin roof, there are steps you can take.

However, keep in mind that no roof will ever be completely soundproof.

Tighten down roof fasteners.

Contrary to what most people may think, metal roofs are not noisier than other popular roofing materials.

But if it wasn’t installed according to industry standards, the metal roof can be noisy during heavy rains. A large factor influencing the amount of noise is how roofing fasteners were installed.

  • Are there too few of them?
  • Are they loose?
  • Are they in the right location?

As the roof expands and contracts with varying temperatures, the problem will get worse over time. Inspecting the roof fasteners and ensuring they are tightened down will help reduce the amount of noise.


Add insulation and ceiling finishing.

Barriers between the roof and interior space will reduce the amount of noise during rainstorms. If your roof was installed with the proper type of underlayment by a qualified metal roofing contractor, this step should not be necessary. 

Two popular choices include more attic insulation and finishing vaulted ceilings and enclosed porches.

Adding attic insulation will significantly decrease the noise from a poor metal roof installation, and rooms with unfinished vaulted ceilings or enclosed porches will become less noisy with the addition of drywall finishes.

Spray foam insulation and rigid foam insulation are two popular options, both of which will absorb the most noise to reduce the volume level inside the home.

Consider the shape of the roof

Roof shape is one of the biggest factors influencing the amount of noise a metal roof creates.

Standing seam metal or flat metal roofs are directly on top of the roof deck. Consequently, they vibrate less and create less noise than roofs with a more standard roof profile.

But most homes don’t have a flat roof profile. Usually, the roof shape rises and has dormers or other complexities. This will cause the roofing material to be stiffer than those installed on a flat roof. And ultimately, the stiffness of the material increases the noise level of the roof.  


Roof underlayment dampens noise.

Foam insulating panels and other forms of roofing underlayment greatly dampen noise created by severe storms. That's why installing a foam-insulating or nylon underlayment must be performed during the installation. However, if the contractor fails to perform this key step, you will experience the type of noise that gives people pause when considering buying a metal roof.

With the proper materials and correct installtion, there is virtually no need to worry about excessive noise.

One of the greatest ways to ensure a quiet metal roof is to install it over an existing asphalt shingle roofing system. If it can be done properly and in line with local building codes, a metal roof installed directly over a shingle roof will create a highly effective soundproofing layer.
