It’s important to note that uncoated metal roofing products may require sound-proofing underlayments during the installation process. This means that the noise impact on the roof is significantly reduced. Stone-coated metal roofing has several layers of coating which, besides being effective for corrosion resistance and increasing tensile strength, also act as an additional noise barrier. How Stone-Coated Metal Roofing Absorbs Sound The thicker the coating and the more irregular the surface texture, the more effective a roof is at disrupting and dampening the reverberation of sound waves.įor example, stone-coated metal roofing products are peacefully quiet in the rain due to their intricate textures and sound-absorbing cushion of roofing granules. But as soon as those building components are added, noise levels return to what could be generally expected with any other roofing material.īut metal roofing products are more advanced than a flat, uncoated sheet of metal. Without the roof deck, insulation and underlayment, an uncoated sheet of metal will sound loud in the rain. If you’ve ever been in a garage, shed or structure that lacked a complete roof assembly, you likely noticed noise and reverberation from the rain. The structure of a roof plays an important role in noise reduction, as well. A flat, uncoated sheet of metal–like the smooth surface of a drum–has no way to shorten the prolonged sound reflection, known as reverberation.

Preventing sounds from hitting hard, flat surfaces is key to noise reduction. We’ll get right to the point–no, metal roofs are not loud in the rain. This is one of the most frequently asked questions we hear from homeowners interested in metal roofing.
