The Truth About Sound Emission in Metal Roofing

Table of Contents


Metal roofing has been a topic of discussion for many homeowners and builders alike. One of the most common misconceptions surrounding metal roofing is its sound emission, especially during rain. Let’s debunk some myths and provide clarity on the subject.

Debunking the Myth: Is Metal Roofing Noisy?

The age-old belief that metal roofs are noisy primarily originates from experiences with barns or patio awnings where there’s no barrier between the individual and the roof. However, modern metal roofing systems have evolved significantly. The Roofing Center, a leading roofing service in Fort Collins CO, often addresses this concern with clients. The truth is, with the right installation and underlayment, metal roofs can be as quiet as any other roofing material.

Sound Levels: Understanding Decibels

To understand the noise levels, one must first grasp the concept of decibels (dB). Sound or sound pressure is measured in dB. For context, the softest sound detectable by the human ear is 0dB, while the loudest is over 175 dB. For a comfortable conversation, sound levels shouldn’t exceed 70 dB. Prolonged exposure to levels above 85 dB can harm one’s hearing. Notably, a variation in sound pressure isn’t discernible to the human ear unless there’s an increase of at least 8 dB.

A study by The Acoustic Group of the University of Lulea, Sweden, aimed to measure the sound emitted when rain hits different roofing materials. The results were surprising to many: metal roofs did not produce a significantly higher sound level than shingles. The difference was a mere 6dB.

Factors Influencing Sound Emission

Several factors influence the sound emission of a metal roof:

  • Construction Method: Metal roofs installed over open framing will indeed produce a louder sound compared to those installed over a solid roof deck. The solid deck acts as a buffer, absorbing or muffling the sound.
  • Underlayment: Most metal roofing products today come with an underlayment material that absorbs sound. This underlayment plays a crucial role in reducing noise.
  • Existing Layers: In many re-roofing projects, metal is installed over existing shingle layers. With the combination of shingles, roof deck, attic space, and insulation, homeowners often report hearing rain on their skylights rather than their metal roofs.

Tailoring to Preferences

The Roofing Center, one of the top Fort Collins roofing companies, believes in tailoring solutions to individual preferences. If homeowners cherish the gentle pitter-patter of rain on their roofs, installations can be adjusted to enhance this sound. Conversely, if they view it as noise, they can be assured that with the right measures, a metal roof can be as quiet as any other material.

In Conclusion

Metal roofing has come a long way, and its sound emission is no longer a significant concern with the right installation techniques. Whether you’re a roofer from Fort Collins or a homeowner seeking roof repair in Fort Collins, it’s essential to be informed and make decisions based on facts rather than myths. The Roofing Center is always here to guide and provide the best roofing solutions tailored to individual needs.
