Will A Metal Roof Be Noisy? Reducing Noise With Metal Residential Roofing Options

Posted on

Metal roofing is one of the most durable and environmentally friendly options available for homeowners, but many people might default to asphalt or wooden shingles simply because traditional metal roofs have a bad reputation for being too loud when it rains or hails. However, while older "tin" roofs may be deafening in a thunderstorm, modern metal roofing can actually be quite quiet. If your new metal roof is loud, there are some things you can do to fix it. 

Fasten The Roof Correctly

One of the reasons why metal roofs can be loud is when the roof is not fastened properly for the material. Too few fasteners can mean that the metal pieces rattle when they are struck by rain or hail, amplifying sound instead of muting it. Simply installing the roof in accordance with the instructions given by the manufacturer will help to make sure that your metal is secured. Also, metal roofs will expand and contract in cold and hot weather, so if there are not enough fasteners, pieces can because too loose or tight, which will also increase the noise level. 

Put Some Layers Between Your Rooms And Your Roof

Modern home building techniques can also stop sound waves from reaching the interior living space. Noise can be reduced by insulating attic spaces, adding wood or drywall to ceilings, and installing a thick sub-roof underneath the metal finishing material. Proper insulation is not just a good investment for sound-proofing, but it is wise because it will help to reduce lost heat through the roof, which will save you money and extend the lifespan of your roof. 

Get High Quality Shingles

Not all metal roofs are created equal. If your roof is well insulated and fastened down tight, another reason why your metal roof is still loud could be that the roofing material itself is not as high quality. Thinner metal sheets are more susceptible to vibration. Flat sheets also do not have any hollow spaces where sound could amplify. Corrugated metal, on the other hand, is louder. To reduce the noise level of your roof, you might need to replace the metal with thicker, flatter sheets that are more weather and wind resistant. Older roofs that have severe metal fatigue also fall into the noisy category for the same reason: weak metals will move more, so they will be noisier.

Redesign Your Home

In some cases, the metal roof will not be the only culprit as to why your house seems to rattle when it rains. Open concept layouts, as well as vaulted ceilings with little or no attic, can transmit and amplify any sound, especially if the surfaces inside the home do not help with sound wave absorption. For example, if you have tile floors and decided to use wall plaster instead of drywall, your house will naturally echo sounds from a metal roof more easily. To reduce the amount of sound left to "bounce" of the walls, use drapes at the windows, and help to absorb sounds with area rugs and wall hangings. 

Add The Extras

If your roof is minimalist-- simply a sub-roof with the metal shingles lain over top, it will be louder. Having a residential roofer come and install a sound barrier underneath your current metal roof will help tremendously with noise reduction. Also, if you currently do not have a metal roof, but would like one, talk to your roofer about simply building the new roof over the old material, as some asphalt or wooden shingles can act as an extra sound-proof layer. 

A metal roof does not have to translate into a noisy house if it is installed and designed correctly. Talk to a roofing company like Davis Bros Roofing about sound-reduction options for your metal roof.
