Do Metal Roofs Make Noise When It Rains? 5 Proven Ways to Reduce Noise

Metal roofs have gained significant popularity among homeowners for their durability, energy efficiency, and modern aesthetic appeal. However, one of the most common questions people ask is: Do metal roofs make noise when it rains? This concern often stems from the perception that metal amplifies sound, making it noisier than other roofing materials. While there is some truth to this, modern metal roofing systems are designed to minimize noise and can even be quieter than traditional roofs with the right measures in place.

Does Metal Roof Make Noise in Rain? – The Answer

The short answer is: No, they don’t have to be noisy if properly installed and soundproofed. Modern metal roofing systems are designed with features that minimize noise, often making them quieter than traditional roofs.

In this blog, we will explore the factors contributing to metal roof noise, compare it with other materials, and provide actionable solutions to reduce rain noise on metal roofs. Let’s dive in!

Do Metal Roofs Make Noise When It Rains?

The perception that metal roofs are excessively noisy comes from older installations, such as barns or sheds, where metal sheets were directly attached to the structure without insulation or soundproofing. In such cases, rain can indeed sound loud as it directly hits the surface. However, residential metal roofs are far more advanced.

Modern metal roofing systems include underlayment, insulation, and other soundproofing measures that significantly reduce noise levels. When properly installed, a metal roof can be as quiet as an asphalt shingle roof. The key lies in understanding the factors that contribute to noise and addressing them effectively.

Factors Contributing to Metal Roof Noise

Several factors determine how noisy a metal roof might be during rain:

1. Lack of Insulation: Thin metal panels with no insulation can amplify the sound of raindrops. For more information on how insulation can make a significant difference, you can explore What is Roof Insulation? Its Different Types.

2. Roof Design: Large, flat panels can produce more noise compared to textured or ribbed designs that help disperse sound.

3. Attachment Method: Metal roofs installed without proper underlayment or fasteners may vibrate and produce more noise.
4. Rain Intensity: Heavy rain or hail will naturally produce more noise, regardless of the roofing material.
5. Environmental Factors: Homes in open areas or near large water bodies may experience louder sounds due to echoes.

By addressing these factors, you can enjoy the benefits of a metal roof without worrying about excessive noise.

How Loud is a Metal Roof During Rain?

While the sound of rain on a metal roof may seem louder in theory, the difference is often negligible in practice. Studies show that a properly installed metal roof produces noise levels similar to other roofing materials, such as asphalt shingles or tiles. For example:
• Metal Roof (With Insulation): Approximately 50-60 decibels during moderate rain.
• Asphalt Shingles: Approximately 40-50 decibels.
Without insulation, however, metal roofs can reach up to 70 decibels, which is comparable to a conversation in a busy restaurant. Adding soundproofing measures significantly reduces this gap.

Noise Levels

Decibels (dBA) measure the intensity of sound. For context:

• A whisper is about 30 dBA.
• Normal conversation is around 60 dBA.
• A lawnmower is about 90 dBA.

According to the Acoustic Group at the University of Lulea, Sweden, rain on asphalt shingles is about 46 dBA compared to rain on a metal roof at 52 dBA. So, what does that mean? Since most humans can’t distinguish between sounds less than eight decibels apart, the noise difference between metal and shingle roofs is undetectable.

5 Proven Ways to Reduce Rain Noise on Metal Roofs

To ensure your metal roof remains quiet during rain, consider implementing these soundproofing methods:

1. Use Soundproof Underlayment

   • A high-quality underlayment acts as a buffer between the metal panels and the roof deck, absorbing sound and reducing vibrations.
   • Popular materials include foam, rubber, or synthetic felt.

2. Install High-Quality Insulation

   • Insulation in your attic or ceiling is crucial for soundproofing. It dampens the sound of rain and improves your home’s energy efficiency.
   • Fiberglass and spray foam are excellent options for noise reduction. You can read more about insulation options in our article 5 Best Attic Insulation Options in 2025: Pros & Cons.

3. Opt for Thicker Metal Panels

   • Thicker panels produce less noise as they are less prone to vibration.
   • Discuss thickness options with your contractor to balance cost and performance.

4. Add Suspended Ceilings

   • Installing a suspended ceiling below your roof adds an extra sound barrier.
   • This option is ideal for retrofitting homes with existing metal roofs.

5. Apply Soundproof Coatings

   • Sound-dampening coatings or membranes can be applied to the underside of the metal panels to reduce noise transmission.
   • These coatings also help prevent corrosion and improve the roof’s longevity.

By combining these methods, you can significantly minimize rain noise on your metal roof and enhance overall comfort.

Noise Comparison: Metal Roofs vs. Asphalt Roofs

When it comes to noise, how do metal roofs stack up against asphalt shingles? Here’s a quick comparison:

Asphalt Shingles:

• Naturally quieter due to their dense composition.
• Do not require extensive soundproofing measures.

Metal Roofs:

• Can be equally quiet with proper insulation and underlayment.
• Offer superior durability and longevity compared to asphalt.
  While asphalt shingles may seem like a quieter option initially, the advanced soundproofing techniques available for metal roofs make them a viable and long-lasting alternative.

FAQs about Metal Roof Noise

1. Can you stop rain noise on a metal roof?

   Yes, with proper soundproofing measures like underlayment, insulation, and coatings, you can significantly reduce rain noise.

2. Will your metal roof make noise when it rains?

   Not necessarily. A properly installed metal roof with adequate soundproofing can be as quiet as traditional roofing materials.

3. Are metal roofs noisy when it rains or hails?

   Metal roofs can be noisier during hailstorms than rain, but soundproofing measures help minimize this.

4. How does a metal roof compare to an asphalt roof in terms of noise?

   Metal roofs with soundproofing are comparable to asphalt roofs in noise levels, while offering superior durability.

5. What’s the best way to soundproof a metal roof?

   Using a combination of underlayment, insulation, and soundproof coatings provides the best results.

Conclusion

So, do metal roofs make noise when it rains? The answer depends on how they are installed and soundproofed. Modern metal roofing systems are equipped with advanced materials that make them as quiet as any other roof type. By investing in soundproofing measures such as underlayment, insulation, and coatings, you can enjoy the benefits of a metal roof without the noise.
