Is A Metal Roof Noise

When installed correctly your metal roof should be just as quiet as an asphalt shingle roof.

Is a metal roof noise.

When a metal roof is installed over a solid roof deck like most homes have it produces an outstanding sound barrier. Metal roofing registered at 52db from rainfall while asphalt shingles registered 46db. The metal roof reflects noise away from your home and provides a dense cover that noise does not easily penetrate. Depending on the materials used during installation it is possible to experience excessive noise during rain and hail.

While the shape of the metal versus a flat metal profile may have some impact on noise levels it s the stiffness strength and quality of the material that is especially influential on how noisy the roof will end up being. Most metal roofing materials can be installed on gently pitched roofs without leaking. Sure metal roofs can be loud in the rain but that s what happens when it s not done right. This perception usually comes from people who have stood under a barn or shed with a metal roof during a storm and heard the raindrops hitting a roof with no underlayment or insulation.

But that is not how residential re roofs are done today. The stronger and more complex a metal roof quality is the stiffer the roof material will be and that will play a significant role as to how much the roof might vibrate. The air space between the metal roof and the sheathing beneath it serves to muffle sound quite well. Metal roofs have always been perceived as being noisy especially when it rains.

Sure metal could be noisier than other types of roofing especially during. The roofs that gave metal a reputation for being noisy were the ones installed generations ago with nothing between the metal panels and the buildings below except wood purlins and thin air which left nothing to deaden the sound. Minimum roof pitch typically is 3 in 12 this means the roof rises 3 inches for each horizontal foot. Maximum shedding of rain and snow.

Though listed here as a con this particular drawback doesn t need to be a given. However in a test by the acoustic group in sweden researchers found that metal roofs emit rain noise softer than normal conversation and only slightly louder than a soft whisper. But when metal roofs are installed properly sound dampening is achieved through quality underlayment.
