7 Ways to Soundproof a Metal Roof

Here’s how you can go about soundproofing your existing metal roof.  Once you’re done with soundproofing your metal roof, the results should be a soundproof roof as quiet as an asphalt shingle roof!

#1 Soundproof the Attic

If you have an attic area, this is a great way to insulate your metal roof at home and reduce the noise!

By completely soundproofing your attic, you will NOT ONLY have the metal roof soundproofed but have an extra layer or physical barrier that will help with noise reduction.

You can simply place sound-dampening materials on the walls, floor, and ceiling of your attic.

#2 Insulate the Walls

Soundproofing the walls will GREATLY help to reduce noise. Not only will it give you privacy between rooms at home, but you will also not hear metal roof noise coming from the outside.

#3 Add Sound Deadening Material to the Ceilings

This is great whether you have an attic at home or not.

By soundproofing the CEILING on your top floor, or the ceilings in your entire house, you can block out the sounds from impact, like hail or a heavy rainstorm.

You can do this by placing sound dampening or sound-deadening materials, like mass-loaded vinyl and acoustic panels.

#4 Use Roof Underlayment

This method only works if you’re installing a new metal roof in your home. So if you have an existing roof with a different material, then you can skip to the next effective method.

A roof underlayment is basically creating a waterproof barrier between the roof deck and metal roofing.

In addition to providing your metal roof with extra protection from water leaks, a roof underlayment also helps with blocking sound from entering.

To help you with the noise level, install plywood or Orient Stand Board at the lowest level of the metal roof before placing your metal sheeting.

You can reduce metal roof noise transmission with underlayment materials, such as foam insulating panels or nylon mats made from entangled nylon filaments installed correctly between the roof sheathing and the metal roofing.

#5 Roofing Profile: Choose the Right Roofing Styles

Again, this is only if you’re installing a new roof at home.

Your choice of the shape of roofing sheets could affect whether it has noise problems or not. The roofing profile you choose DETERMINES how much noise it makes.

Flat or vertical seam metal roofing would sit more flush on your roof deck and will rattle less.

A corrugated roofing style has gaps between it and the roof’s surface. So this would vibrate more and create more sound than seam metal roofing.

Of course, even if you choose a flat metal roof, it would still make metal sounds. So be sure to soundproof the roofing as well.

#6 Make Sure There Are No Fastener Problems

This is a pretty QUICK solution and can help keep your metal roof in good condition.

Check the roofing fasteners. Make sure they’re firm and tight.

Make sure that metal-to-wood roof screws were used during installation.

If there aren’t enough fasteners, or if there are fastener issues, the roof would move, making loud rattling noises.

#7 Maintain Your Roof

This excellent solution not only helps with metal roof soundproofing but makes sure that your existing metal roof stays in good shape for a LONG time.

The fasteners on the metal roof could unfasten as time passes. So to make sure it stays in good shape and make sure you have routine maintenance.

If your house is small enough, you can simply walk the perimeter of your house and check if there are any loose bits on the metal roof by yourself.

If you have a tall house, have professional help.

How Do I Soundproof My Ceiling?

There are many ways you can soundproof this. Here are some things you can do to achieve a soundproof ceiling. Soundproofing the ceiling can definitely help with that God-awful racketing noise.

Soundproof Drywall Ceiling

Adding a finished drywall ceiling can do WONDERS.

SOUNDPROOF DRYWALLS are thicker than regular drywalls. This is especially important if you have a metal roof over the ceiling.

To improve soundproofing in the drywall, you can fill it with sound-absorbent material. One example is fiberglass, which can absorb sound.

  • A single-layer soundproof drywall is great for airborne noise but does almost NOTHING for impact sound on a metal roof.
  • Adding double-layer drywall IMPROVES the performance. It makes the ceiling thicker, thus helping to reduce some of the metal roof noise from impact.

Decoupled Ceiling

This method includes having a double layer drywall and one layer of Green Glue.

You also use soundproof clips to clasp the hat channels apart from the joists and drywall.

This is great for reducing impact noise.

Floating Joists

This is a decoupling technique great at reducing impact noise on your metal roof.

Install insulation material in between the sets of joists. 

Just don’t COMPRESS or pack the insulating material, as this will be bad for the newly fixed joist!

Adding Soundproofing Materials

You can layer on sound deadening or sound-absorbing materials onto the ceiling.

This would be soundproof paint, acoustic tiles or Mass Loaded Vinyl, and acoustic foam. To get to any hard-to-reach areas, you can use spray foam insulation. This can make a great foam gap filler.

Just make sure you attach them well. You don’t want your ceiling FALLING DOWN on you!

Benefits of Soundproofing Metal Roofs

Why would you need to soundproof a metal roof?

Temperature Insulation

Metal roofs aren’t the best at insulation on their own. That’s why you need to add extra sound-damping insulation.

And that’s where soundproofing comes in.

Soundproofing metal roofs improves the insulation of your home, allowing you to keep the air inside cool during summer and warm during winter.

Sound Protection During Rain or Extreme Weather

Metal roofs on their own can be noisy when the weather is bad. With soundproof metal roofs, you won’t have to hear loud pitter-patter sounds of raindrops or hail.

This is ESPECIALLY great for families with young children. Children don’t tend to like the sound of extreme weather like hail storms…or thunder!

It gets even worse on a plain metal roof because, without proper layering, the sound may just AMPLIFY.

Relaxing Home Environment

Not having loud sounds coming from your roof is definitely A LOT more RELAXING than having noisy metal roofs!

Roofs are meant to protect you from the elements, but if it makes you feel stressed, then you need to find a way to make it less stressful.

Easier Conversations

Not having to yell over a noisy roof is great. So sound dampening can definitely help to reduce the need for this.

Better Sleep

With a quieter environment, you would have a better sleep. Soundproof metal roofs won’t disturb you anymore at night if you reduce the noise it makes!

Besides, who wouldn’t love sleeping in peace?

The Benefits of Metal Roofs

What do homeowners hate more than the sound of rain?

ROOFING COSTS!

Metal roofs have a reputation for being one of the more affordable options in the market compared to clay, stone, and wood. But that’s not all.

There’s also longer life expectancy, fire resistance, and lower energy bills. If you soundproof it, you can enjoy the benefits of a metal roof without the noise factor.

JUST MAKE SURE you’re also using great-quality sheet metal on your roof. Low quality only leads to higher costs in the future!

How Much Does It Cost to Soundproof Ceilings?

The cost varies depending on the method you choose to soundproof and the type of items you choose to use. But these are the prices for some of the sound deadening and soundproof roofing materials.

  • Soundproofing drywall can cost as much as $40.
  • Soundproofing paint would be around $230-$280.
  • Acoustic tiles are $10 per 20-inch square.
  • Acoustic foam panels would be $10-100 depending on the size.

Of course, these are just noise-reducing materials. We didn’t take into account structural changes, like if you plan to replace your noisy roof entirely!

Can You Soundproof Existing Ceilings?

This would be a great way to soundproof your metal roof. But how would you go about doing this?

If you already have your ceiling, you probably don’t want to tear it down just to add drywall into it. But don’t worry! There are soundproofing methods you can do WITHOUT TEARING IT DOWN.

In fact, keeping it can help reduce noise better than if you were to tear it down and start over.

You can do this by installing SOUNDPROOFING MATERIALS. This is primarily what you can do to reduce noise; and also the cheapest method.  

You can also install a DROP CEILING. This is one way to surely soundproof your metal roof at home.

What Is the Cheapest Way to Soundproof Metal Roofing?

The cheapest way you can soundproof a metal roof is to soundproof the ceiling under it.

To do this, you can use acoustic insulation on the ceiling. You can also use soundproof paint as well as Green Glue to add an extra layer of soundproofing.

Soundproofing is a project that is relatively simple to do. Just make sure to be EXTRA THOROUGH during the installation process.

Once you do this, you can GREATLY REDUCE the noises from your metal roof at an affordable price.

Pros and Cons of Having a Metal Roof

Here is a list of the pros and cons of having a metal roof.

Pros of Having a Metal Roof

1. DURABLE and LONG LASTING

With a metal roof, you can expect a life span of 40 to 70 years! They also often come with a 30 to 50-year manufacturer’s warranty.

It also won’t corrode, thanks to rust-proof coatings. By contrast, traditional asphalt roofing typically lasts 12-20 years.

2. Environmentally Friendly

Asphalt roofs are a petroleum product and thus increase dependency on fossil fuels.

On the other hand, metal roofs are made of at least 25 percent recycled materials and are 100 percent recyclable.

They are also…

  • A great foundation for other eco-friendly initiatives, like solar panels and systems for harvesting rainwater.
  • Do not have to be replaced as much as asphalt roofs, making for less waste of roofing material.

3. Energy Efficient

You can save money on cooling and heating costs with this roof.

Metal roofs reflect solar radiant heat instead of absorbing it, reducing cooling costs by as much as 25 PERCENT, especially during summer.

To add to this, some metal roofing is coated with special reflective pigments to minimize heat. This can help keep you cool and comfortable even without an air conditioner.

4. Stylish

Metal roofs today look AMAZING. It’s a far cry from the metal roofs of the past. There are a wide variety of designs you can choose from, more than the typical asphalt roof.

It comes in 100 different colors to choose from, compared to the 20 that asphalt roofs offer.

So it’s safe to say that metal roofs are the roofs of the future.

Cons of Having a Metal Roof

1. Expensive

According to Home Advisor’s Guide to Roofing Costs, metal roofs can cost $120 to $900 per 100 square feet. Higher-end metals run as much as 10 times the cost of asphalt shingles.

Not only is the material more expensive, but the price of installation labor costs more because of the specialized training, knowledge, tools, and equipment it entails. 

BUT REMEMBER!

A metal roof lasts twice as long as an asphalt roof, meaning it’s also well worth it. Not to mention, a metal roof is more energy-efficient.

2. Can Be Dented

Although metal roofs nowadays are designed to withstand abuse from extreme weather, some metal can still be dented from hail or falling branches.

Depending on the type of roof, you may not even want to walk on them. Not solely because of denting issues, but during wet weather, it’s extra slippery.

But if you have a steel roof, you won’t have to worry about this too much. If you have an aluminum or copper roof, you may want to be more careful with it.

3. Noisier Than Others

This is a big con to some people. But if you read through this article, you already know that it’s not that difficult to counter this with soundproofing!

Time to Enjoy Peace and Quiet!

So if you’ve made it this far, it’s safe to assume you already KNOW what to do to soundproof your noisy metal roof!

If you have a good roofing company install your metal roof, it should be relatively quiet to begin with. These are just tips to reduce the noises further.
