Are Metal Roofs Loud in the Rain

This is one of the most frequently asked questions we hear from homeowners interested in metal roofing, so we’ll get right to the point–no, metal roofs are not loud in the rain.

But it’s important to note that metal roofing is a broad term that can be broken down into subcategories. The different types of metal roofing can vary drastically in appearance, quality, performance and noise levels in the rain.

An uncoated sheet of aluminum on top of a barn or shed is noisier in the rain than metal roofing products used on homes and commercial properties. For example, stone-coated metal roofing products are peacefully quiet in the rain due to their intricate textures and the sound-absorbing cushion of stone granules.

The structure of a roof plays an important role in noise reduction, as well. 

A metal roof on a barn or shed lacks a complete roof assembly. The higher construction standards for residential and commercial properties require a roof deck, insulation and underlayment. This considerably dampens the sound of rainfall on the roof. With a complete roof assembly in place, the noise from rain on a metal roof is similar to any other roofing material.

If you’re in search of a metal roof that’s quiet in the rain, here’s what you need to know: 

· What to look for in a metal roof that is quiet in the rain.

· The stone-coated secret for a quiet metal roof. 

What to Look for in a Metal Roof That is Quiet in the Rain

Preventing sounds from hitting hard, flat surfaces is key to noise reduction from the rain.

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.

Reverberation is like an echo, but instead of hearing the sound again a split second later, the sound lasts a bit longer. Imagine being in a big empty room and clapping your hands. You'll hear the sound of your clap bouncing off the walls and the floor, and it will keep echoing for a moment before it fades away.

If a roof is made of a flat and uncoated sheet of metal, like that on a barn or shed, the noise from the rain will bounce and echo much longer.

On the other hand, a coated and textured metal roof, such as stone-coated metal roofing, will absorb the noise from the rain.

Simply put, reverberation makes the sound of rain louder and longer lasting when the roof reflects sound instead of absorbing it. 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. 

The Stone-Coated Secret for a Quieter Metal Roof

As mentioned above, the thicker and more irregular texture of a roof, the more it will disrupt, dampen and absorb sound from the rain.

Stone-coated metal roofing has several layers of natural stone granules 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.

In addition to being peacefully quiet in the rain, a stone-coated metal roof is one of the most durable roofs on the market. Stone-coated metal roofs are engineered to protect your home from nearly anything Mother Nature has to offer, including: Hurricanes and Tornadoes; Hail Impact; Class A Fire Rating.

Stone-coated metal roofs also come with an extremely high ROI, thanks to their durability, longevity and energy efficiency.

· A stone-coated metal roof can protect your home from more than just the rain. A metal roof has a lifespan that is 2 to 3 times longer than traditional roofing materials like asphalt, tile and wood.

· Metal roofs are one of the most energy-efficient materials on the market and can reduce cooling costs by up to 25%.

· A modern metal roof can increase home value by up to 6%.
