Did you know shingles get layered like fish scales?

Funny, I always thought the metal valleys looked a bit out of place, but after patching the same leaky spot three times, I caved and went with metal anyway. Not gonna lie, it’s not winning any style points, but at least my living room ceiling isn’t growing a new water feature every spring. The rattle when it rains is real though - sometimes I think it’s hailing when it’s just a drizzle.

I did try closed-cut valleys on the shed last year. Way easier to work with than woven, and it blends in better with the shingles. Haven’t noticed any leaks yet, but then again, that roof doesn’t take as much of a beating as the main house.

Living near the coast definitely makes things trickier. My neighbor’s metal valley started rusting after just a few years - guess salt air really does a number on anything metal. If I had to do it all over again, I’d probably spring for something less industrial-looking, but at this point I’ll settle for dry floors and call it good.

Metal valleys definitely aren’t winning any beauty contests, but I get where you’re coming from - sometimes you just want the leaks to stop, no matter what it looks like. Did you use galvanized or aluminum? I’ve seen galvanized rust out quick near the coast, but aluminum holds up a bit better, though it dents easier. That rain noise is no joke either... ever try putting a bit of underlayment or foam beneath to muffle it? Not perfect, but helps a little. Closed-cut valleys do look cleaner, but I always wonder if they’ll hold up as long in rough weather. Guess time will tell.

- Used aluminum last time - galvanized just didn’t last with all the salt in the air where I am.
- You’re right, dents show up fast, but at least it’s not rusting out on me.
- Tried foam strips under the metal... helped a bit, but rain still sounds like someone drumming up there.
- Closed-cut valleys look better, but I’ve seen them leak after a few years if the shingles aren’t lined up right.
- Anyone ever mess with woven valleys? I heard they’re tougher but a pain to install.

Galvanized never stood a chance for me, either - coastal air just eats it up. Aluminum’s holding up, but yeah, those dents are annoying. I’ve tried woven valleys on a couple of jobs. They’re definitely sturdier, but getting the overlap right is tedious and you burn through shingles faster. Anyone have luck with synthetic underlayment for noise? I’m still chasing that “quiet rain” dream...

I totally get the “quiet rain” thing - grew up in a house with a metal roof, and every storm sounded like a drumline. When we reroofed my uncle’s place last year, we tried synthetic underlayment hoping it’d help. Honestly, it was a bit quieter than felt, but not by much. The real difference came from adding a thicker layer of insulation under the decking. Not cheap, but it actually muffled the noise way better than I expected. Still, nothing’s ever as silent as you hope when the rain really comes down...

Funny timing - just had my first “real” rainstorm in this house, and I was totally caught off guard by how much louder it was than our old apartment. We’ve got asphalt shingles, and I always thought they’d be quieter than metal, but when it’s pouring, it’s still pretty noticeable. I guess the insulation (or lack of it) makes a bigger difference than I realized. Kind of wish I’d paid more attention to that when we bought the place... live and learn, I guess.

That’s actually a pretty common surprise - people think asphalt shingles are going to be super quiet, especially compared to metal, but when it’s coming down hard, you still hear it. I’ve noticed that too, especially in houses where the attic insulation is on the lighter side. Did your old apartment have a flat roof or maybe more insulation between the ceiling and the roof deck? Sometimes apartments just have more “stuff” between you and the outside noise.

Funny thing about shingles being layered like fish scales: it helps with water runoff, but doesn’t do much for sound. The gaps between layers aren’t sealed tight, so rain can kind of “drum” on them and echo through the attic if there’s not enough to muffle it. Have you poked around in your attic at all? I’ve seen some places where there’s barely any insulation up there, or sometimes it’s just old and settled down to almost nothing.

I always thought metal roofs would be way louder too, but after working on a few, I realized if they’re installed with good underlayment and insulation, they can actually be quieter than a poorly insulated shingle roof. Kind of weird how much difference that makes. Did you notice any drafts or temperature swings in your place before? Sometimes noise is just one sign that the insulation isn’t doing its job.

If you ever end up adding more insulation (blown-in is pretty popular), it can help with both sound and keeping things warmer or cooler. Not always cheap, but sometimes local programs help cover part of the cost. Anyway, you’re definitely not alone in being surprised by how much rain you can hear - seems like one of those things nobody warns you about before moving in...

I’ve always been a bit skeptical about how much difference shingle layering really makes for noise. In my experience, the biggest factor is what’s between the roof and your living space, not so much the shingles themselves. I had a place with brand new architectural shingles - supposed to be “premium” - but with barely any insulation in the attic, it sounded like hail every time it rained hard. Meanwhile, my neighbor’s house with older shingles but a foot of blown-in cellulose was way quieter.

I do wonder if anyone’s actually measured decibel levels under different roofing setups. There’s a lot of marketing around “quiet” shingles, but I’m not convinced it matters unless you address the insulation and air gaps underneath. Has anyone here tried adding soundproofing specifically for rain noise? I’ve heard of folks using dense batts or even foam board up in the attic, but I’m not sure how much real-world difference it makes compared to just adding more standard insulation.

Also curious if anyone’s noticed a trade-off between sound and ventilation - sometimes when you seal things up too tight for noise, you end up with moisture issues.

I get where you’re coming from, but I’ve actually noticed a bit of a difference with certain shingle types, especially when it comes to those heavier laminated ones. On my last place, switching from basic 3-tabs to thicker architectural shingles did seem to muffle the rain a touch, though not nearly as much as adding insulation. It’s subtle, but I think the extra mass and overlap might help a bit with sound dampening - just not enough to skip out on attic insulation. Still, I wouldn’t totally write off shingle choice if you’re already due for a new roof. Just gotta balance that with cost, because, yeah, insulation gives way more bang for your buck. Ventilation is tricky - after I added more batts, I had to double-check my soffit vents weren’t blocked, or else the humidity spiked fast.

You’re spot-on about the difference between basic 3-tab shingles and the heavier architectural ones. The added mass and the way those laminated shingles overlap does provide a bit more sound dampening, especially during heavy rain. It’s not dramatic, but it’s there - kind of like the difference between a hollow-core and solid-core door. I’ve seen similar results on inspections, though I always caution folks not to expect miracles just from a shingle upgrade.

Insulation really is the heavy hitter for noise reduction and temperature control. I’ve been in attics where someone beefed up the insulation but neglected ventilation, and you can almost feel the air getting thick - humidity spikes, and then you start seeing issues like mold or even premature shingle aging from trapped heat. It’s a balancing act. Good call on double-checking your soffit vents after adding more batts; that’s a detail a lot of homeowners miss, and it can really bite you later.

Cost-wise, you nailed it too. If you’re already due for a roof replacement, it makes sense to consider architectural shingles for the marginal benefits - looks, slight sound improvement, maybe even a bit more wind resistance depending on your area. But if noise is your main concern, attic insulation is usually where you’ll get the most return for your dollar.

One thing I’ve seen trip people up is thinking the underlayment (the layer beneath the shingles) will make a big difference for sound. In reality, most standard felt or synthetic underlayments don’t do much in that department - it’s really all about insulation and mass.

If you’re in a climate with wild temperature swings or lots of storms, sometimes those heavier shingles can help with durability too. But yeah, always keep an eye on ventilation when you add more insulation - ice dams in winter or humidity in summer can sneak up fast if airflow gets blocked.

You’ve got a good handle on it. Roofing’s one of those things where every little detail seems to matter just enough to keep you on your toes...

You’re right about the ventilation - people always seem to overlook that when they’re piling on insulation. I’ve seen more than one attic turn into a sauna because someone blocked the soffits. And yeah, architectural shingles look better and might help a bit with noise, but I wouldn’t count on them for much beyond curb appeal and maybe a little extra wind resistance. Insulation’s where the real difference is, at least in my experience. Still, you’ve clearly done your homework, which is more than I can say for most folks tackling a roof project.

- Ventilation’s the unsung hero, for sure. Seen too many folks stuff their attics like a turkey and wonder why it’s roasting up there.
- I’ll give architectural shingles this: they do look sharp, and they seem to hold up a bit better in our windy springs. But yeah, not magic.
- Insulation’s where I noticed the biggest change - kept the house warmer in winter, didn’t turn it into an oven in July.
- One thing I learned the hard way: don’t let anyone talk you into covering up those soffits “just for more R-value.” Sweaty attic = mold city.
- Honestly, half the battle is just paying attention to the details... which most people skip when they’re in a hurry to save a buck.

Funny you mention the soffits - my neighbor did exactly that, stuffed insulation right up against them, and a year later he’s pulling out moldy plywood. I get wanting to squeeze every bit of R-value, but if the attic can’t breathe, it’s just asking for trouble. Did you end up using baffles or anything to keep airflow going?

On the shingle front, I swapped to architectural last spring after a nasty windstorm took out a chunk of my old three-tabs. They do look better and seem to be holding up so far, but I’m not convinced they’re worth double the cost in every case. Maybe it depends on how much wind you get? For me, peace of mind was worth the splurge.

Insulation made a bigger difference than I expected too. My upstairs used to feel like an oven by July - now it’s actually bearable. Curious if anyone’s tried those radiant barriers under the roof deck? Heard mixed things about whether they’re worth it or just hype.

if the attic can’t breathe, it’s just asking for trouble.

Couldn’t agree more. I’ve seen folks try to max out insulation and end up with a science experiment in their attic. Baffles are a must, in my opinion - otherwise you’re just trapping moisture. As for the architectural shingles, I get the appeal, but unless you’re in a high-wind area or really care about curb appeal, I’m not sure they’re worth double either.

About radiant barriers - I’ve heard they help in southern climates, but up north? Not convinced. Anyone actually see a drop in temps after installing one?

You’re spot on about attic ventilation. I’ve seen people block soffit vents with insulation and end up with moldy sheathing - never fun to fix. Baffles are cheap insurance, really. On the radiant barrier thing, I tried it in my Michigan place a few years back. Didn’t notice much difference in summer temps, honestly. Down south, maybe it’s worth it, but up here? Not sure the return’s there unless you’re dealing with a lot of direct sun on a low-slope roof.

Yeah, I’ve seen that mistake with soffit vents more times than I can count. Folks get up there with a roll of insulation and just stuff it in, not realizing they’re choking off the airflow. Next thing you know, you’ve got black spots creeping across the sheathing and everyone’s blaming the roof when it’s really a ventilation issue. Baffles are one of those things that seem optional until you see what happens without them.

On radiant barriers, I’m with you - up north, the payoff just isn’t there most of the time. I inspected a place in northern Indiana where they’d stapled up foil everywhere, but the attic was still roasting in July. Maybe it helps a bit with ice damming if you’ve got a weird roof shape, but honestly, proper insulation and airflow do way more for comfort and longevity. Down south or out west where the sun’s relentless? Different story.

I always tell people: focus on keeping those vents clear and making sure your insulation isn’t blocking anything. The rest is just fine-tuning.

Funny thing, I learned about the fish scale thing the hard way when I tried patching a spot after a windstorm. Thought I could just tuck a shingle under and call it good, but nope - water found its way in anyway. Turns out, the overlap is what keeps everything dry, just like scales on a fish. And yeah, if your attic can’t breathe, doesn’t matter how perfect your shingles are, you’ll still end up with problems. I’ve seen more moldy sheathing than I care to admit... always comes back to airflow.

Funny how you don’t really think about the overlap until you’re up there fixing a mess. I learned that lesson after a hailstorm - tried to save a few bucks by just sliding new shingles in, but water still got in around the edges. Airflow’s another thing folks overlook. Have you ever tried adding more vents after the fact? I’m curious if it actually helps with moisture or if it’s too little, too late.

Adding vents after the fact can help, but it’s not always a magic fix for moisture issues. I’ve seen folks cut in extra roof or soffit vents thinking it’ll dry things out, but if the insulation’s already soggy or you’ve got trapped moisture, it doesn’t really solve the root problem. Ran into that on a ranch house last summer - owner thought more airflow would save his attic, but we had to pull up half the deck to deal with the rot first. Sometimes, you gotta address what’s already gone wrong before tweaks like extra vents make a real difference.

Had a similar situation on my place about six years back - thought just adding a few more vents would handle the humidity up there, but it turned out half the insulation was already soaked and moldy. Ended up pulling all of it out, running a couple fans for days, and replacing several sheets of decking before even thinking about new vents. Really wish I’d checked for signs of moisture earlier, like those little water stains around the nails or that musty smell every time I popped the attic hatch.

Honestly, I think a lot of folks underestimate how much trouble can start under those shingles, even if they look fine from the outside. The way they’re layered is clever, but if water sneaks underneath - say from ice dams or wind-driven rain - it doesn’t take long for things to go sideways. I’ve also noticed that in places with big temperature swings (I’m in the Midwest), condensation is a bigger culprit than actual leaks sometimes. That’s where ventilation helps but only after you’ve got everything else dry and sealed up.

What’s your take on synthetic underlayment versus old-school felt? I swapped to synthetic last time since it was lighter and didn’t wrinkle as much in the humidity, but I’ve heard mixed opinions about how well it breathes. Anyone here stick with felt and have better luck with moisture control? Or maybe you tried one of those peel-and-stick ice barriers along the eaves? I’m curious if that’s made a noticeable difference for anyone, especially in areas that get a lot of freeze-thaw.

Anyway, I’m with you - sometimes you gotta do the dirty work first before any “quick fix” like extra vents actually does anything. Curious if anyone else has found a good way to spot attic moisture issues early, before they turn into a full-on project...
