Three Ways To Sound-Proof Your Commercial Roofing

Posted on: 10 April 2015

Commercial roofing keeps the interior of a building dry, deflects precipitation and heat, and is easily repaired or replaced. However, commercial roofing is rarely soundproof, and everything outside of the building (and some things inside) causes the roof to echo with noise and vibrations. It also makes it difficult to hear loudspeaker announcements and voices reverberate, causing confusion about what has been said. If you are willing to spend a little extra money, there are three ways you can soundproof your commercial building.


Commercial buildings often have single layer roofs made of metal or lightweight concrete. To decrease the amount of sound you hear in a rainstorm and/or reduce the vibrations of thunder, a contractor can build up a layer of insulation under the typical commercial roof. The insulation is often blown into spaces after a wooden or plasterboard ceiling has been installed. The blown insulation becomes tightly compacted, and very little sound or vibration can get through.

Alternative Metal Roofing

Instead of the standard warehouse style of metal roofing, choose styles that more closely resemble traditional roofing materials or shaker tiles. These facsimile materials create less noise when inside noise bounces off the ceiling and less outside noise because the roofing is not a straight, thin, slick panel upon which the rain can beat. If you combine a more residential or rustic looking metal roof with insulation, you have an excellent soundproof roof on your commercial building.

Green (Vegetative) Roofs

Another way to soundproof your commercial roof is to go au naturel. Adding sod and greenery to the roof allows the vegetation to absorb not only the precipitation, but absorb the sound as well. It does not do much for interior echoes, but it dulls almost all outdoor noise when you are inside. 

Discuss Your Options with Your Contractor

When you meet with a roofing contractor (such as one from, discuss with him or her reasons why you want to soundproof your commercial roof. If you also want to make the roof look less like a warehouse roof and make it look more attractive, you do not necessarily have to soundproof it. The above options are focused on reducing sound and vibration, but your contractor can make suggestions on how to improve the appearance as well as reducing sound and vibration. None of these options really requires that you remove your current roof, which is why other business owners find them so appealing.
