Finally tackled that metal edging thing on my roof

You’re spot on - water’s sneaky, and it’ll find its way in even if you think you’ve sealed everything up tight. I’ve seen a lot of folks just caulk the edge and call it good, but honestly, that’s usually just a band-aid. If you’re seeing soft decking or any hint of mold after pulling back the metal, it’s probably time to swap out that section. Patching works for minor stuff, but once the wood’s compromised, you’re just delaying bigger headaches down the road. I always say: if your screwdriver sinks into the wood instead of bouncing off, replacement’s the safer bet.

Had a similar situation last fall - thought I’d done a thorough job sealing the flashing, but after a heavy rain, there was still dampness under the eaves. Pulled up the metal and sure enough, some of the decking was spongy. Ended up replacing about a 3-foot section. It’s tedious work, but honestly, once wood gets soft, patching just doesn’t cut it for long-term peace of mind. I do think sometimes folks go overboard with replacement though - if it’s just surface mold and the wood’s still solid, I’ll treat and seal rather than rip everything out. Just depends how far gone it is.

I’ve run into that same debate - replace or just treat? Had a spot over a porch where the decking looked rough but wasn’t soft, just a bit of mildew. I scrubbed it, hit it with a borate solution, and sealed it up. That was two years ago and it’s still holding up fine. But yeah, once it’s spongy, I don’t mess around. It’s wild how fast water can sneak in under metal if the flashing isn’t perfect. Sometimes feels like you’re chasing leaks more than fixing them...

I get where you’re coming from - sometimes treating and sealing is enough, especially if the wood’s still solid. But I’ve seen cases where mildew was just the tip of the iceberg, and a year or two later, hidden rot showed up under the surface. Moisture can travel in weird ways, especially around metal edges and flashing. I tend to err on the side of caution and probe deeper if there’s any doubt. It’s not always obvious what’s going on underneath until you open it up...

I get the urge to dig in and check everything, but honestly, sometimes that just leads to more headaches than it’s worth. I had a spot by my chimney where I thought for sure there was hidden rot - turned out it was just surface mildew from a leaky gutter. Treated it, sealed it up, and five years later it’s still solid. Not saying ignore warning signs, but sometimes you can overdo the “just in case” thing and end up tearing apart perfectly good wood. Just my two cents...

- Totally get where you’re coming from. I’ve seen people rip out half their eaves just because they spotted a little discoloration, only to find it’s nothing major.
- That said, I’ve also seen folks ignore stuff that looked minor and then a year later, boom - major rot, way more expensive fix.
- For me, I try to poke around with a screwdriver first. If the wood feels solid, I’ll clean it up and keep an eye on it. If it’s soft or crumbles, then yeah, time to dig deeper.
- Mildew’s pretty common around chimneys and gutters, especially if you’re in a damp area. Quick bleach scrub and seal usually does the trick.
- Overkill can be a pain (and expensive), but ignoring stuff isn’t great either. Guess it’s all about balance.
- On metal edging - if you’re sealing up those joints right and keeping water away, you’re probably good for years. Just don’t skip checking under any suspicious spots before calling it done… learned that one the hard way after missing a tiny leak last fall.

I get the whole “poke with a screwdriver and move on if it’s solid” approach, but I’d be careful relying just on that, especially around metal edging. In my experience after big storms, water can sneak in behind flashing and rot the sheathing underneath without showing much on the surface. Had a case last year where everything felt fine up top, but when we pulled back the metal, there was hidden damage along the drip edge. Sometimes it’s worth pulling a couple fasteners just to peek underneath - saves a lot of trouble down the line.

Had almost the same thing happen on my garage roof last fall - looked fine from the outside, but when I finally pulled a couple screws, the wood underneath was soft as a sponge. Figured I was saving money by not digging deeper... ended up costing me more in the end. Sometimes a little extra poking around is worth it, even if it feels like overkill.

That’s exactly the kind of thing I’m worried about with my place. I keep thinking, “If it looks okay, maybe I can just leave it alone for another year…” but then stories like yours make me second-guess that logic. Did you end up having to replace a whole section of the roof, or was it just patchwork? I’m still learning what’s normal wear and what’s a red flag.

I had a similar moment with my deck - looked fine until I stepped in the wrong spot and nearly went through. Guess there’s something to be said for poking around, even if it feels like you’re making more work for yourself. But how do you know when to stop digging? Sometimes I feel like if I start pulling things apart, I’ll never get it back together.

Anyway, thanks for sharing your experience. Makes me feel a little less paranoid about checking things twice... or three times.

But how do you know when to stop digging? Sometimes I feel like if I start pulling things apart, I’ll never get it back together.

That’s the million-dollar question, right there. I’ve been in the exact same boat - sometimes literally, with all the water that’s come through my ceiling over the years. My place is about 40 years old, and every time I notice something a little off (like a shingle that looks curled or a bit of soft wood on the deck), I have this internal debate: “Is this just normal aging or am I about to open a can of worms?”

When I finally tackled my own roof edging, it started as a “quick patch” situation. Just some rust on the flashing, nothing major… or so I thought. Once I got up there and started poking around, I realized the metal was actually letting water seep under the shingles in one spot. Ended up having to replace about a three-foot section of both the edging and some underlying plywood. Not a full roof job, but definitely more than just slapping on some caulk.

What’s helped me is making a checklist - if I see soft spots, discoloration, or anything that feels spongy underfoot (deck or roof), that’s my signal to investigate further. But if it’s just cosmetic stuff - minor stains, surface rust - I’ll usually monitor it for changes before tearing anything apart. Sometimes you can overdo it and create more work than necessary (been there), but ignoring things can get expensive fast.

One thing I wish someone had told me earlier: take photos each season. That way you can compare year-to-year and spot changes before they turn into big problems. It’s saved me from second-guessing myself more than once.

And yeah, stepping through a deck board is a rite of passage at this point... At least you caught it before it got worse. There’s always that balance between being proactive and not driving yourself nuts with worry. For me, erring on the side of caution has usually paid off in the long run - even if it means spending a few weekends with a pry bar and a lot of YouTube tutorials.

If you’re ever unsure whether something’s “normal wear,” sometimes just tapping around with a screwdriver can tell you more than meets the eye. If it crumbles or feels soft, probably time to dig deeper; if not, maybe just keep an eye on it for now.

It’s all part of the fun (and stress) of owning an older place…

That’s the tightrope, isn’t it? I’ve seen folks rip up half their roof chasing a “maybe” leak, only to realize it was just condensation from a bathroom vent. On the flip side, I’ve also seen people slap some caulk on rusted flashing and hope for the best - six months later, they’re calling me because their ceiling looks like a water park.

Honestly, I’m always a little skeptical when someone says “it’s probably nothing.” If you’re seeing soft spots or that spongy feel, that’s not normal wear - that’s your house waving a red flag. But yeah, not every stain means disaster. Around here (Midwest), ice dams cause all sorts of weird marks that don’t always mean rot.

I do like your idea of tapping around with a screwdriver. That’s old school but it works. And I can’t tell you how many times I’ve said, “Just one more shingle…” and ended up with a full Saturday project. Sometimes you gotta trust your gut, but don’t let paranoia take over either.

That screwdriver trick is underrated - sometimes the simplest tools tell you the most. I’ve definitely been guilty of “just checking one more spot” and suddenly I’m knee-deep in shingles, wondering where my Saturday went. Around here (Great Lakes), I’ve noticed that what looks like a leak is often just frost sneaking in under the metal edging. Still, I’d rather poke around and find nothing than ignore it and end up with a soggy attic. There’s a fine line between being thorough and tearing up half your roof for no reason, though.

That screwdriver test is a lifesaver, but I’ve definitely gone overboard with it too. Last fall, I started poking around for a “tiny leak” and ended up pulling half the drip edge off before realizing the condensation was just from a cold snap. Around here (northern Indiana), frost and wind seem to find every gap. What I learned: check the attic first for wet spots, then work outside only where you see something suspicious. Saves a lot of shingles and time... but yeah, sometimes you just get carried away.

I’ve done the same - started with a screwdriver, ended up with a bigger project than planned. One thing that’s helped me: I use a cheap moisture meter in the attic before touching anything outside. It’s saved me from ripping up perfectly good shingles more than once. Those Indiana winters are brutal on roofs... condensation can look a lot like a leak if you’re not careful.

I get where you’re coming from with the moisture meter - definitely handy for tracking down attic dampness. But I’ve seen a fair number of false negatives with the cheap ones, especially in colder months. Sometimes by the time you spot condensation or a leak in the attic, the underlying issue outside has already gotten worse. Indiana winters are rough, but wind-driven rain or ice dams can sneak water in spots those meters just won’t catch.

Personally, I like to do a visual inspection up top first, even if it’s just a quick look from a ladder. You’d be surprised how often flashing or that metal edging starts to pull away after a freeze-thaw cycle. Found a tiny gap on my own place last year - no moisture inside yet, but it would’ve turned into a headache come spring.

Not saying skip the meter, but don’t trust it alone. Sometimes your eyes and a flashlight beat any gadget, especially with these unpredictable Midwest seasons...

- I get what you’re saying about visual checks, but honestly, I’ve had the opposite problem a couple times - missed leaks that only showed up with my (admittedly mid-range) moisture meter.
- Visual inspections are great for catching obvious stuff like pulled flashing or missing shingles. But water can travel in weird ways under metal roofs, especially after a wind-driven rain. Sometimes there’s zero visible sign until insulation’s already soaked.
- Maybe it’s just my luck, but last March I caught a slow drip inside the attic that was totally invisible from outside. Meter picked it up before anything stained the drywall.
- Not saying meters are perfect - cheap ones definitely give weird readings in cold weather - but if you calibrate or use one that does both pin/pinless modes, you can catch stuff early.
- For me, it’s more about using everything together: quick outside look, then spot checks inside with the meter around trouble spots (chimney, valleys, etc). Layering tools seems to cover more bases.

Curious if anyone else has found certain brands of meters way more reliable? Mine’s a Protimeter, not cheap but saved my bacon twice now...

That’s been my experience too - no single method catches everything. I’ve had leaks show up months after a “clean” visual check, and the meter was the only thing that tipped me off. Midwest weather is brutal on roofs, especially with all the freeze/thaw cycles. Protimeter’s a solid choice - pricey, but honestly worth it if you’re managing multiple properties or just want peace of mind.

I’m with you on the Midwest weather - my roof’s taken a beating from all that freeze/thaw too. I’ve found even with regular checks, something always slips through. Ever tried using thermal imaging along with the meter? I borrowed one once and it actually picked up a cold spot near my skylight that I’d totally missed. Curious if anyone’s had luck with more eco-friendly sealants for those trouble spots... I’m always looking for greener fixes, but sometimes they just don’t hold up as well in these temps.

Thermal imaging’s a game changer, right? I borrowed one from a buddy last winter and found a drafty spot behind my chimney that I’d never have noticed otherwise. As for eco-friendly sealants, I’ve tried a soy-based one on a couple seams - worked okay in fall, but by February it started cracking. Maybe it’s just our wild temp swings here. Has anyone had better luck with those newer hybrid sealants that claim to be both green and flexible? I’m tempted, but not sure if they’re worth the extra cost.

Hybrid sealants are interesting, but I’m a bit skeptical about their claims in extreme climates. I’ve seen a few of the “green and flexible” types hold up okay on south-facing seams, but around chimneys or valleys - especially where temps swing hard - they can still crack or pull away after a tough winter. Honestly, I’ve had better luck with high-quality polyurethane or modified silicone, even if they aren’t as eco-labeled. If you’re sealing metal edging, surface prep is just as important. Clean, dry, and primed goes a long way, no matter what sealant you use.
