How noisy can metal roofs be? This is one of the most common questions that dog Bryan homeowners. These homeowners have different opinions on the amount of “roof noise” they can tolerate. Most of them do not have a problem with the typical sound that raindrops make, while others would prefer to minimize sounds. But the tolerable noise from a roof that homeowners can withstand is based on the construction and installation quality of that roof. Quieter compared to many other materials The human ear is known to have the ability to register a broad range of volumes. Humans are able to hear a low noise of up to 0dB and a loud noise of up to 175dB (the threshold for pain is about 130dB). General conversations are often about 70dB. Logical conclusions may cause the homeowner to think that the metal roofs are noisier compared to other roofing material types, such as composite shingles. But according to some studies by the Acoustic Group, researchers found out that metal roofs generate rain noise that are a bit softer compared to normal conversation and just slightly louder compared to a soft whisper. From the studies, a metal roofing and asphalt shingles recorded 52dB and 46dB respectively, from rainfall. Since normal conversation happens at 70dB, the metal roofing doesn’t have a substantial impact on the levels of sound. Roof Construction details One reason why the asphalt shingles seem to work better in reduction of noise compared to metal roofing is the system components which happen to be layered together. They serve and act as sound dampeners. Metal roofs which are made on open frames tend to produce louder sound compared to those made on solid decks. In Bryan, roofing regulations permit installation of roof decks beneath metal roofs to act as sound dampeners; just the same way asphalt shingles can dampen sound. Currently, there are only a few cases of metal roofing without sound absorbing underlayment material. If you have skylights in your home, then you can test the principle on rainy days. When closely listening to that sound, you’ll realize that it is being generated from the skylight and not from the roof. Skylights often open up to the open air, permitting sound waves to freely roam inside the living space. On the other hand, the roof is backed up by material layers which absorb sound waves What is the ideal sound? The acceptable sound levels from a roof vary from one homeowner to another. Light sleepers might not prefer much sound from their roof. Conversely, some people like the traditional soft sound of rains. In case a home owner likes a roof that produces more sound, the local roofer must install the roof on a unique framing system which will serve as a minor amplifier, working to transmit more sound to open air inside the living spaces. When it comes to homeowners who love the appearance of a metal roof, but cannot withstand the sound associated with this roof when it rains, the roof must be created with extra layers to act as sound dampeners.
