This is hands down the most common concern we hear: "Won't it be really loud when it rains?" Here's what we tell homeowners based on actual installations and feedback.
The Myth
"Metal roofs are incredibly noisy during rain and hailstorms, making your house sound like you're inside a drum."
The Reality
A properly installed metal roof with adequate insulation and underlayment is actually quieter than many other roofing materials.
Where the Myth Comes From
The noise reputation comes from old agricultural buildings and poorly installed metal roofing. Think about:
- Barn roofs with no insulation or underlayment
- Metal panels attached directly to roof decking
- Thin gauge materials that “oil can” (flex and pop)
- Large, open spaces that amplify any sound
These installations ARE noisy - but they're nothing like a modern residential metal roof system.
What Makes Modern Metal Roofs Quiet
Quality Underlayment
Modern synthetic underlayments provide excellent sound dampening between the metal and roof deck.
Proper Insulation
Adequate attic insulation absorbs sound just like it prevents heat transfer.
Solid Roof Deck
Metal installed over solid plywood or OSB decking versus open purlins makes a huge difference.
Thicker Gauge Materials
24 or 26-gauge panels are much quieter than thin agricultural-grade materials.
Real-World Sound Comparison
Here's what we actually hear in properly installed systems:
During Normal Rain
- Quality Metal Roof: Barely audible, similar to asphalt shingles
- Asphalt Shingles: Light patter sound
- Clay Tiles: Very quiet
During Heavy Rain/Hail
- Quality Metal Roof: Noticeable but not overwhelming
- Asphalt Shingles: Also quite audible
- Clay Tiles: Loudest during hail due to impact sounds
When You Might Still Have Noise Issues
Honestly, there are some situations where metal roofs can be noisier:
- Vaulted ceilings with no attic space for insulation
- Budget installations that skip proper underlayment
- Very thin gauge materials (not what we recommend)
- Direct attachment to structural steel (commercial applications)
How to Ensure a Quiet Installation
Our Recommendations:
- Use quality synthetic underlayment (not basic felt paper)
- Ensure adequate attic insulation (R-30 minimum for Alberta)
- Choose 24 or 26-gauge materials minimum
- Install over solid decking when possible
The Bottom Line
We've installed hundreds of metal roofs, and noise complaints are extremely rare when the job is done right. Most customers are surprised by how quiet their new metal roof actually is.
The bigger question isn't whether metal roofs are noisy - it's whether your installer knows how to build a quiet system. That's where working with experienced contractors makes all the difference.
