A properly installed residential metal roof, built as a complete assembly with solid decking, underlayment and insulation, is not meaningfully louder than asphalt shingles. Industry guidance puts the measured gap at just a few decibels, a difference most people can barely detect. What decides how quiet your roof feels is the assembly beneath the panels, not the metal itself.
TL;DR:
- Require contractors to document continuous sheathing, the underlayment type, attic insulation, and ceiling finish; panel specifications alone do not describe the sound control assembly.
- Entangled filament underlayments reduced sound by 9.5–13.5 dB in tests; with insulation and a gypsum ceiling, reductions exceeded 20 dB.
- If the roof is already installed, attic insulation and air sealing are the least costly fixes; adding a ceiling layer or replacing sheathing costs more.
- MBMA found dents up to 0.160 inch deep did not cause functional coating failure, but warranties may exclude cosmetic damage.

How loud is a metal roof compared with asphalt shingles?
The reputation for being loud comes from barns, sheds and carports, where bare metal sits over open framing with nothing underneath to absorb sound. A residential roof is a different animal. Industry summaries point out that the “metal roofs are loud” belief traces back to exposed-metal structures with no sheathing or insulation, and that full residential assemblies are typically as quiet as other roofing types when properly built.
Residential metal roofs installed over solid decking, underlayment and insulation produce rain and hail noise often within just a few decibels of asphalt shingles. A few decibels is a small step on the scale, the kind of change you notice only when you compare the two roofs side by side.
Even so, the absolute numbers move with the test setup. When you read a decibel figure, check what was under the panels:
- Decking type: solid plywood or OSB sheathing damps the panels, while open framing lets them ring.
- Insulation: batts or blankets in the attic absorb sound that would otherwise reach the rooms below.
- Ceiling: a finished drywall ceiling blocks far more sound than bare rafters.
- Underlayment: a thicker, cushioned layer under the panels takes energy out of each raindrop.
- Measurement spot: a reading taken in the attic reads louder than one taken in a bedroom.
Our advice is simple: ask any contractor to describe the whole assembly, not just the panel.
Why does the full roof assembly control noise?
Rain noise is mostly an impact-sound problem. Drops strike the panel, the panel vibrates, and the vibration travels through whatever it touches. Anything that stiffens, cushions or absorbs along that path lowers what you hear inside.
Continuous sheathing is the first lever. Industry guidance explains that metal roofs over open framing are inherently louder than roofs over continuous sheathing, because solid decking steadies the panels and reduces resonance.
Underlayment is the second. Entangled-filament products such as Enkamat and Colbond, tested in Europe, reduced sound levels by roughly 9.5–13.5 dB compared with panels installed directly over a weather barrier. Paired with a gypsum ceiling and thermal insulation, those same tests showed reductions above 20 dB. Rigid, layered deck systems that combine composite base panels, foam insulation and mineral board are also designed to cut thermal expansion noise.
Insulation is the third. Faced and unfaced metal building insulation can absorb sound inside the assembly and cut noise by up to 5–6 dB. MBMA/NAIMA testing also found that roof assemblies with fiberglass insulation and ceiling finishes reached substantially higher STC and OITC ratings than uninsulated metal assemblies.
Panel choice matters at the margins:
- Gauge: panel stiffness can affect how much it flexes and “drums.”
- Profile: panel shape can affect stiffness and how much it vibrates.
- Pitch: a steeper roof sheds water faster, which can change how rain strikes and sounds.
- Ceiling finish: gypsum and airtight sealing can help form an interior sound barrier.
Pro Tip: Ask your installer to put the underlayment, sheathing and insulation spec in writing. A quote that only names the panel leaves the quiet part of the roof to chance.
What can you do to reduce noise before, during and after installation?
Most of the quieting happens in decisions made before the first panel goes on, so we rank the options by how early they fit. If you are comparing materials first, our metal roof vs. shingle comparison covers the wider trade-offs.
- Start with continuous sheathing. Solid decking beneath the panels is the single biggest structural step, and it is far easier to do during a full replacement than later.
- Choose the underlayment on purpose. A cushioned or entangled-filament layer takes the sting out of impacts. Our guide to roof underlayment types explains the options.
- Consider panel gauge and profile. Panel stiffness can affect flutter and drumming.
- Fasten correctly and limit unsupported spans. Loose or widely spaced panels rattle and amplify vibration.
- Insulate and seal the attic. Add insulation and close air leaks so sound has fewer paths into the living space.
- Finish the ceiling well. A gypsum ceiling can help reduce sound transmission.
- Retrofit if the roof is already on. Add attic insulation, add a secondary ceiling layer, or install damping membranes where access allows.
On cost and complexity, the low end is adding attic insulation and sealing gaps. The middle is upgrading underlayment during a re-roof. The high end is replacing sheathing or adding double gypsum ceilings. Interior fixes help too: sealed, well-fitted rooms and quality doors, such as the noise-reducing interior door options our neighbors at One Day Doors & Closets describe, cut how much roof sound carries through the house.
Pro Tip: If you can only afford one upgrade, put it where sound has to travel through the most material: the attic insulation and ceiling, not the panel.
How do rain and hail differ for noise and damage?
Rain and hail are two separate concerns. Rain noise is a steady, soft impact problem that assembly damping controls well. Hail adds sharp, high-energy hits, so you get a louder moment and a durability question at the same time.
On durability, impact research is encouraging. Ice-ball testing with balls of 19–51 mm found that metal panels resist functional damage better than many other roofing materials. MBMA hail studies on coated steel standing seam panels found that typical hail divots up to about 0.160 inch deep do not cause functional coating failure or faster corrosion, and that such panels have performed in service for decades.
MBMA found that hail divots up to about 0.160 inch deep did not produce functional coating failure. Dents can look cosmetic while the panel keeps doing its job.
Before you buy, ask these questions:
- Does the panel carry a hail or impact rating, and who tested it?
- Does the warranty cover cosmetic dents, or only functional failure?
- What does a post-storm inspection involve, and who performs it?
- How does the manufacturer define “hail damage” in writing?
How does metal roof noise compare with other roofing materials?
Heavy, dense materials such as clay tile and concrete tile have mass working for them, so rain tends to sound muted. Asphalt shingles sit in the middle: they absorb some impact, which is why they are the usual benchmark. Metal over a full assembly lands close to shingles, as the measurements above show.
Lightweight membrane systems tell the opposite story. Research on ETFE and similar membranes notes acoustic weaknesses from low mass per unit area, and found that extra layers, air chambers and rain-suppressor meshes cut rain noise. That is the same principle that quiets a metal roof: add mass, add layers, add absorption.
Noise is only one trade-off. Lifecycle studies note that standing seam metal roofs often last 40–60 years and can have lifecycle advantages over asphalt shingles. If you are weighing materials for a local home, our guide to choosing the best roofing material walks through durability, cost and sound together.
What about wind, snow and other weather?
Rain and hail get the attention, but other weather shows up in how a roof sounds.
Wind is mostly a fastening story. A well-fastened roof stays quiet in a gale, while loose trim, flashing or panel edges can hum or flutter. If you hear whistling or rattling, check the edges and ridge details first.
Snow can change how a roof sounds. Snow on the panels may affect the sound, while sliding snow can drop off with a thump. Consider snow guards where appropriate.
Temperature swings cause a different sound: ticking or popping as panels expand and contract. Rigid deck systems and properly designed clips let panels move without binding, and that reduces expansion noise. Heat affects the assembly in other ways as well. Test-roof research at Oak Ridge shows that insulation, air gaps and ventilation change how heat flows through the attic and ceiling, which hints that cavity and decking choices shape acoustic behavior too.
If a noise only appears in one kind of weather, that clue helps a roofer find the source quickly: wind points to fastening, heat points to expansion, and rain points to the assembly.
Which maintenance practices keep a metal roof quiet?
A quiet roof on day one can get louder if small problems build up. A few habits keep the sound where it started.
- Check fasteners. Over the years, screws can back out or washers can wear. Snug, intact fasteners keep panels from rattling.
- Inspect flashing and trim. Loose edges, ridge caps and penetrations are the usual sources of wind noise.
- Keep debris off the panels. Branches and built-up leaves hold moisture and can scratch coatings, while loose debris can drag and rattle in wind.
- Look after the attic. Insulation that settles, gets wet or is displaced loses its sound-absorbing value. Seal new air leaks after any wiring or vent work.
- Re-inspect after storms. After heavy hail or wind, a quick walk-through by a qualified roofer catches loose pieces before they become a nightly annoyance.
Regular inspections, including after severe weather, are a sensible practice. If you want a professional set of eyes, we handle roofing repair and replacement for local homeowners.
What are the most common myths about metal roof noise?
“Metal roofs are always loud in rain.” They are not. The loud-roof picture comes from bare metal over open framing. A residential roof built as a full assembly measures within a few decibels of shingles.
“The panel is what makes noise.” Much of the sound comes from the structure under the panel. Continuous sheathing, cushioned underlayment and attic insulation do most of the quieting, as covered above.
“Hail will wreck a metal roof.” Impact testing says otherwise. Many metal panels show only cosmetic divots under common hail, and those divots do not necessarily mean functional damage.
“You can’t fix noise after the roof is on.” Attic insulation, air sealing and ceiling changes may help reduce the sound you hear.
“Quiet means expensive.” Some fixes cost little. Adding attic insulation and sealing gaps sits at the low end, and better underlayment during a re-roof is a modest step compared with the total job.
What I would require from a contractor
My checklist is short. I would want continuous sheathing and a named underlayment in writing. I would ask about attic insulation and air sealing, the ceiling finish plan, and ask which panel profile and gauge the installer recommends and why. If structural sheathing has to change, or you need a whole-roof replacement, or you want a warranty-backed install, hire a professional. If that is you, we install and repair roofs in Albuquerque, and our roofing installation guide and roofing services page show how we work. Our estimate fee is $75 one-off.

FAQ
Is it normal for a metal roof to make noise?
Some sound is normal, mostly light patter in heavy rain and occasional ticking as panels warm and cool. Over solid decking with insulation, rain noise is often within a few decibels of shingles. Loud rattling or banging usually points to loose fasteners or trim.
How do you stop a metal roof from making noise?
Start with the assembly: continuous sheathing, cushioned underlayment, attic insulation and a finished ceiling. Entangled-filament underlayments have cut sound by roughly 9.5–13.5 dB in tests. For rattles, tighten fasteners and secure loose flashing.
Are metal roofs noisier than shingles?
Not meaningfully when installed as a full assembly. Industry guidance puts the difference at a few decibels, which is barely noticeable. Bare metal over open framing is the case where metal is clearly louder.
What should I check before choosing a metal roof?
Check the sheathing type, the underlayment, the attic insulation and the ceiling finish, then confirm the panel gauge and profile. Ask how the warranty treats hail dents and what a post-storm inspection involves. Those details tell you far more about future sound and durability than the panel brand alone.
