How to assure homeowners that a metal roof can quietly protect their home.
How many times have you heard the comment that metal roofs are loud in the rain? It is by far one of the most frequently asked questions from homeowners who are interested in metal roofing. We will cut to the chase—no, metal roofs are not loud in the rain.
Preventing sounds from hitting hard, flat surfaces is key to noise reduction. 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.
The structure of a roof plays an important role in noise reduction, as well. 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. Without the roof deck, insulation and underlayment, an uncoated sheet of metal will sound loud in the rain. But as soon as those building components are added, noise levels return to what could be generally expected with any other roofing material.
But metal roofing products are more advanced than a flat, uncoated sheet of metal. 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.
For example, stone-coated metal roofing products are peacefully quiet in the rain due to their intricate textures and sound-absorbing cushion of roofing granules.
How stone-coated metal roofing absorbs sound
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. This means that the noise impact on the roof is significantly reduced.
It’s important to note that uncoated metal roofing products may require sound-proofing underlayments during the installation process. Modern synthetic soundproofing underlayments cost around $8 per square foot, not counting contractor time and labor expenses, so it’s important to note that an uncoated metal roof may require additional costs during installation.
Additional benefits of stone-coated metal roofing
A roof is the first line of defense against the elements, and a stone-coated metal roof can protect your home from more than just the rain.
