Homeowners in Irvington, NJ often wonder: does a metal roof make more noise than shingles during rain or hail? The short answer is not as much as you think. When installed correctly with proper underlayment and insulation, modern metal roofs produce noise levels comparable to asphalt shingles. This guide breaks down the facts about metal roof noise and provides practical soundproofing solutions for Irvington residents.
Why Metal Roofs Sound Different Than Asphalt Shingles
Metal roofs produce noise because raindrops strike a hard surface directly. Asphalt shingles, by contrast, absorb sound naturally—their granular surface disperses impact noise while the fibrous mat underneath dampens vibrations. However, shingles aren't silent. Heavy rain still creates a noticeable patter, especially in attached homes.
The actual decibel difference between a properly installed metal roof and shingles is typically less than 5 decibels—barely noticeable to most people. The key is understanding what factors control noise levels and how modern installation techniques minimize the gap.
Factors That Control Noise Levels
- Metal type and thickness – Thin corrugated metal amplifies sound. Thicker standing seam panels (24 or 22 gauge) dampen vibrations.
- Roof structure – Solid plywood decking reduces noise. Spaced boards amplify it.
- Underlayment – Rubberized asphalt or foam underlayment absorbs impact noise significantly.
- Attic insulation – Thick insulation (R-38 or higher) acts as a sound barrier.
- Fastening method – Concealed fasteners minimize vibration compared to exposed screws.
- Roof pitch – Steeper roofs reduce direct impact from rain.
Common Myths About Metal Roof Noise
**Myth:** Metal roofs are unbearably loud during rain.
**Truth:** With proper installation, modern metal roofs are only slightly louder than shingles—often indistinguishable once insulation and underlayment are in place.
**Myth:** Metal roofs amplify hail noise to dangerous levels.
**Truth:** While hail impact is louder, soundproofing measures minimize the noise, and the roof remains structurally superior to shingles.
**Myth:** You can't reduce metal roof noise without major renovations.
**Truth:** Adding quality underlayment or increasing attic insulation makes a significant difference without extensive remodeling.
Real-World Noise Comparison: Metal Roof vs. Shingles
Rain noise on a metal roof ranges from 45 to 55 decibels, while asphalt shingles produce about 40 to 50 decibels. The difference is comparable to a quiet conversation versus a library—subtle and easily mitigated with proper installation.
A poorly installed metal roof will be noticeably louder. Gaps, loose panels, or inadequate underlayment amplify noise. Professional installation using sound-dampening techniques brings noise levels down to match shingles. Choose a licensed contractor experienced with metal roofing in Irvington to ensure optimal results.

Effective Soundproofing Techniques for Metal Roofs
Choose the Right Underlayment
Underlayment is your first defense against noise. Rubberized asphalt underlayment absorbs impact and reduces vibration effectively. Some products include a foam core specifically designed to dampen sound. For maximum noise reduction, invest in premium underlayment—the cost difference is minimal compared to the acoustic benefit.
Add Insulation for Sound Dampening
Attic insulation serves dual purposes: improving energy efficiency and blocking sound transmission. Target at least R-38 in the attic for best results.
- Closed-cell spray foam – Seals gaps and adds mass. Excellent for soundproofing.
- Fiberglass batts or blown-in cellulose – Cost-effective options that work well for sound dampening.
Upgrade Your Attic Space
If your attic is unfinished, consider adding sound-deadening materials between the roof deck and ceiling:
- Acoustic panels or mass-loaded vinyl for enhanced sound absorption
- Seal air leaks to prevent noise from traveling through gaps
- Radiant barriers to reduce temperature fluctuations that cause expansion and contraction noises
Hail Noise: What Irvington Homeowners Should Expect
Irvington, NJ experiences an average of 2-3 hailstorms per year, typically with small to medium-sized hail. While hail hitting a metal roof produces a higher-pitched sound similar to a drum—compared to the duller thud on asphalt shingles—the difference is temporary. Metal roofs resist hail damage far better than shingles, eliminating costly repairs.
Preventive Measures for Hail Noise
- Choose standing seam metal panels with thick gauge (24 or 22 gauge) to reduce vibration.
- Install foam-backed underlayment that absorbs impact.
- Add acoustic insulation in the attic directly below the roof deck.
- Consider stone-coated metal tiles, which mimic the sound-dampening properties of shingles.
Long-Term Value: Why Noise Concerns Don't Deter Irvington Homeowners
Metal roofs last 40-70 years compared to shingles' 15-30 year lifespan. They reflect solar heat, reducing cooling costs during Irvington's humid summers, and maintain their acoustic properties over time. Shingles, by contrast, become brittle and noisier as they age due to granule loss.
While metal roofs cost two to three times more than asphalt shingles upfront, they offer long-term savings on energy bills, maintenance, and replacement costs. Investing in soundproofing upgrades is more cost-effective than replacing a shingle roof multiple times over the same period.
Metal roofs also enhance curb appeal with a modern, sleek appearance. In Irvington's diverse housing market, they increase property value and attract buyers seeking durable, low-maintenance homes.
What Local Homeowners Say
Many Irvington homeowners report that after installing a metal roof with proper soundproofing, they barely notice any noise difference. One resident noted, "I was worried about the rain noise, but with the rubber underlayment and extra insulation, it's actually quieter than my old shingles." Others appreciate the peace of mind knowing their roof can withstand severe weather without constant maintenance.
Frequently Asked Questions
- Does a metal roof really make more noise than shingles?
- Not necessarily. With proper installation—including quality underlayment and attic insulation—a metal roof can be as quiet as asphalt shingles. The decibel difference is typically less than 5 dB, which most people cannot distinguish.
- How can I reduce the noise of a metal roof during rain?
- Add rubberized underlayment, increase attic insulation to R-38 or higher, or install sound-dampening materials like foam panels or mass-loaded vinyl. Ensure solid decking and proper fastening to reduce vibrations.
- Is metal roof noise a problem in hail storms?
- Metal roofs can be louder during hail, but the noise is temporary and the roof is more durable than shingles. Standing seam panels with thick metal (24 gauge) and foam-backed underlayment significantly reduce hail noise.
- What soundproofing options are best for metal roofs in Irvington, NJ?
- Rubberized asphalt underlayment and closed-cell spray foam insulation are top choices. They absorb impact noise and improve energy efficiency, making them ideal for the local climate and weather patterns.
- Are there specific metal roof types that are quieter than others?
- Yes. Standing seam metal roofs with thicker gauge steel (24 or 22 gauge) and concealed fasteners are quieter than corrugated panels. Stone-coated metal tiles also mimic shingle sound dampening while providing metal's durability.
