Need advice on replacing an old leaky roof

Not sure I’d stress too much about the shingle color unless you’re in a spot that really bakes in the summer. I’ve had both light and dark roofs, and honestly, attic ventilation made a bigger difference than anything else. If you get the airflow right, the rest tends to fall into place. Just my two cents - sometimes folks overthink the details and miss the basics.

Title: Need advice on replacing an old leaky roof

I get where you’re coming from about not sweating the shingle color too much. I used to think picking the right shade would make a huge difference, but after going through two roof replacements (one on my old house, one here), I’ve realized it’s not as big a deal as people make it out to be - unless, like you said, you’re somewhere that gets roasted in the summer.

What really hit my wallet was fixing poor ventilation. The first time around, I cheaped out and didn’t upgrade the attic vents. Big mistake. Ended up with higher cooling bills and even some mold issues because the air just wasn’t moving up there. Second time, I spent a little extra to get the airflow right, and it paid off. House stayed cooler, bills dropped, and no more weird smells or dampness.

If you’re watching your budget (and who isn’t these days?), I’d say focus on getting solid underlayment and making sure your attic can breathe. Shingle color is more about looks unless you’re in a spot that gets crazy hot. Even then, it’s not a magic fix if the rest of the roof system isn’t up to par.

Anyway, just wanted to back up what you said - sometimes it’s easy to get caught up in all the options and forget that basics like ventilation and good materials matter most. Don’t let the little stuff stress you out too much... roofs are expensive enough as it is.

I’ve been wondering about the best way to actually check if my attic ventilation is doing its job. I mean, I get that more vents = more airflow, but is there a way to tell if it’s balanced right? I’ve read about ridge vents and soffit vents, but not sure how to tell if what I’ve got is enough. Did you notice any specific signs before you upgraded, or was it just the bills and dampness?

Honestly, you can have a ton of vents and still get it wrong if the airflow isn’t balanced. I’ve seen folks just slap on more vents thinking it’ll solve everything, but if your soffit vents are blocked by insulation or there’s not enough intake, the ridge vents won’t do much. It’s like trying to suck a milkshake through a straw with a hole in it - just doesn’t work right.

For me, the first red flag was when I noticed frost on the underside of the roof decking in winter. That, and my attic felt like a sauna in July. Bills creeping up is another giveaway, but honestly, if you’re seeing dampness or mold, that’s already past due for an upgrade.

If you want to check balance, try the smoke test - burn some incense near a soffit vent and see if it gets pulled through to the ridge vent. If it just hangs around, you’ve got a problem. Don’t trust just the number of vents; make sure air can actually move from low to high. Otherwise, you’re just poking holes in your roof for nothing.

That’s a good point about vent balance - just adding more isn’t the answer. I ran into a similar mess on one of my first projects years back. The previous owner had put in a bunch of box vents, but didn’t touch the soffits. When we opened up the attic, half the insulation was jammed right up against the eaves. Practically zero intake. The funny part is, the roofer before us had even upsold “extra ventilation,” but it was all exhaust.

One thing I always check now is actual airflow, not just vent count. Did you notice any signs of rot or delamination on your decking? Sometimes, you don’t even see mold until you pull up the shingles and by then it’s a much bigger job. Curious if you’ve checked how much of your soffit is actually open, or if there’s baffles in place? I’ve seen a lot of insulation crews just block everything off without realizing what it does to the air movement.

It’s wild how much a supposedly “vented” roof can still trap heat and moisture if the setup’s wrong.

That’s spot on about airflow. I’ve seen plenty of roofs with a dozen vents but barely any intake - just like you described, insulation packed tight against the eaves. It’s easy to overlook, but if the soffits are blocked or there aren’t baffles, you’re basically just recycling hot air up there. I’d also double-check for any soft spots on the decking while you’re at it. Sometimes you don’t see the damage until you’re halfway through demo, and then it’s a bigger headache than expected.

Yeah, I learned the hard way about those hidden soft spots - thought I was just swapping shingles, ended up replacing half the decking. If you’re pulling insulation, watch for critter nests too... found a squirrel condo in mine once. Fun times.

That’s wild about the squirrel condo - nature always finds a way, right? When we bought our place last year, I thought “how hard can a roof be?” Turns out, it’s like opening a mystery box. I remember pulling up the first few shingles and feeling pretty confident, but then I hit this patch where the wood just crumbled under my hand. It was like discovering a secret passage, except instead of treasure, it was just rot and old insulation that looked like it belonged in a haunted house.

I get what you mean about those hidden soft spots. It’s almost like the house is keeping secrets until you start poking around. I had this moment where I just sat on the ladder, staring at the sky through the hole I’d made, thinking, “Well, this is definitely not a weekend project anymore.” But honestly, once I got over the initial panic, it felt kind of empowering to tackle it piece by piece. There’s something weirdly satisfying about knowing every inch of your own roof - even if it means dealing with unexpected guests (mine was a family of mice, not squirrels, but still...).

If you’re feeling overwhelmed, just remember that every old house has its quirks. It’s like they’re testing us to see if we’re up for the challenge. And yeah, sometimes you end up replacing more than you planned, but at least you know it’s done right. Plus, there’s a certain pride in looking up and knowing you fixed it yourself - even if it took longer (and cost more) than you thought.

Hang in there. The mess is temporary, but the stories last forever.

That “secret passage” feeling is way too real. The first time I pulled up a shingle and found rot underneath, I just sat there thinking, “Well, that escalated quickly.” Here’s how I tackled it, in case it helps: First, I mapped out the worst spots and worked in sections - trying to avoid opening up more than I could close in a day. It’s tempting to just rip everything off, but unless you’ve got a crew (or endless energy), it gets overwhelming fast.

When you hit those crumbly patches, don’t just patch over them - replace the decking. I learned the hard way that shortcuts just mean you’ll be back up there next year. For insulation, I went with new batts after clearing out the haunted house stuff. Not glamorous, but it made a difference.

One thing I wish I’d done sooner: take photos as you go. It’s weirdly satisfying to see progress, and it helps if you need to retrace your steps. And yeah, expect a few “guests” - I had a raccoon skeleton in mine. Old houses, man... they keep you humble.

Couldn’t agree more with this - patch jobs are just a temporary fix, especially with old roofs. I’d add: if you’re already in there, consider upgrading to better underlayment. It’s not glamorous, but it’s a game-changer for leaks. And yeah, taking photos is underrated. I’ve gone back more than once to double-check what I did. The “guests” are a rite of passage... found a mummified squirrel in mine. Old houses really do keep you guessing.

I swear, old roofs are like mystery boxes - never know what you’ll find under there. I once pulled up a section and found a whole stash of marbles (no clue). Agree on the underlayment upgrade, though. It’s not the fun part, but it saves so much hassle later. And yeah, photos are a lifesaver... especially when you’re trying to remember which beam looked “iffy” after everything’s covered up.

Seriously, I felt that. When we started poking around our attic, I found a bunch of old nails and even a weird little toy car wedged between rafters. About the underlayment - did you go with synthetic or felt? I’ve heard mixed things, and I’m kinda torn. Also, how did you keep track of which beams needed extra attention? Photos help, but sometimes they all look the same in the moment...

About the underlayment - did you go with synthetic or felt? I’ve heard mixed things, and I’m kinda torn.

I get where you’re coming from on the underlayment debate. I know synthetic is all the rage now, but honestly, I’m not totally sold on it for every situation. We went with a high-quality felt on our last project, mostly because I wanted something that’s been proven over decades. Synthetic is lighter and supposedly more durable, but I’ve heard stories about it getting slippery during install, and some brands don’t breathe as well as felt. If you’ve got a historic home or anything with original wood, sometimes felt just plays nicer with the old materials.

That said, I know a lot of folks swear by synthetic for its tear resistance and how it handles water if the shingles take a while to go on. I guess it depends on your climate and how fast your crew works. For us, the peace of mind with felt was worth it, even if it’s a bit heavier and messier.

Photos help, but sometimes they all look the same in the moment...

Totally agree - photos are great until you’re staring at 30 nearly identical shots of beams and can’t remember which one was above the bathroom. What worked better for me was using painter’s tape to mark any beams or rafters that needed extra attention. Just slap a piece on the trouble spots as you go. It’s low-tech, but when you’re crawling around up there, it’s way easier to spot a bright blue strip than to scroll through your phone. I also kept a little notebook with rough sketches and notes, but I’m kind of old-school that way.

And yeah, old roofs really are like mystery boxes. We found a stack of 1940s newspapers stuffed in the eaves - guess that was someone’s idea of insulation back then. Makes you wonder what people will think when they poke around our “modern” fixes in another 80 years...

Painter’s tape is genius - I wish I’d thought of that when I was elbow-deep in insulation dust last year. I’ll admit, I was pretty skeptical about all the hype around synthetic underlayment too. The roofer pushed for it, but I ended up going with felt after seeing how brittle the synthetic got in the sun on my neighbor’s place. Maybe it’s just me, but sometimes “new and improved” isn’t always better, especially for older homes with quirks. And yeah, the weird stuff you find up there... we pulled out a rusted-out coffee can full of marbles from the attic rafters. No clue what that was about, but it definitely made me laugh.

I hear you on the synthetic underlayment. I tried it once and it felt like laying down a giant plastic tarp - just didn’t sit right with me. Did your roofer mention anything about ventilation? Sometimes that gets overlooked, but it can make a huge difference, especially with older houses. And yeah, the attic finds... I once found a stack of 1970s TV Guides up there. No idea why someone would stash those, but hey, at least it wasn’t marbles.

Ventilation was actually one of my main concerns. My contractor seemed focused on the shingles and underlayment, but I had to push for details on ridge vents and soffit vents. With these older houses, you’re right - it’s easy to miss, but it really affects moisture and heat buildup. I’m not convinced synthetic underlayment is always worth the hype, either. It’s supposed to last longer, but if it doesn’t breathe, what’s the point?

I’ve wondered about the synthetic underlayment too. My contractor pitched it as a must-have, but I keep reading mixed reviews, especially for older homes that need to “breathe” more. Did you end up going with ridge vents or stick with traditional box vents? I’m trying to figure out if the extra cost for ridge vents is really justified on a tight budget, or if it’s more of a marketing thing...

I’ve run into the same debate on a bunch of projects, especially with older houses. Honestly, I’ve seen synthetic underlayment work fine, but I get why folks worry about breathability. On my own place (built in the 40s), I went with ridge vents after a lot of back and forth. They weren’t cheap, but the attic’s noticeably cooler now. That said, I’ve also seen box vents do the job just fine if the rest of the attic ventilation is solid. Sometimes I think the “must-have” pitch is a bit much, especially if you’re watching costs.

I’ve noticed similar results with ridge vents, especially on older homes where the attic can get stifling. They’re definitely pricier upfront, but I’ve found they handle airflow better than box vents in most cases. That said, if your soffit vents are clear and you’re not dealing with a complex roofline, box vents can still work out fine. It really comes down to the whole system working together - no single component is a magic fix. Synthetic underlayment’s been reliable for me too, as long as you’re careful about moisture barriers elsewhere. Sometimes the “must-have” lists seem more about trends than actual performance.

RIDGE VS BOX VENTS - WHICH MAKES MORE SENSE?

- I’m in the middle of this same debate. Ridge vents seem like the “modern” choice, but I keep hearing mixed things about their effectiveness if your attic isn’t set up right.
- My builder says box vents are cheaper and easier to install, but then I wonder if I’m shortchanging myself long-term.
- Kinda agree about the “must-have” lists. When I asked around, half the stuff people swore by just felt like upsells.
- Anyone else worried about synthetic underlayment trapping moisture? I’ve read it’s great unless you mess up the vapor barrier elsewhere... which sounds easy to do.

Still not sure which way to go. Leaning toward whatever keeps my attic from turning into a sauna this summer.
