Roof checkups saved me big bucks - anyone else?

Funny, I used to think as long as the shingles looked good, I was in the clear. Turns out, flashing is where my last two leaks started - one at the chimney, one at a vent pipe. Both times it was just a tiny gap I missed on a quick look. Now I use a flashlight and check every seam after big storms, even if it feels overkill. It’s way less hassle than gutting drywall later. Still not convinced caulk alone is enough, though... anyone else layer up with flashing tape?

It’s wild how many folks miss flashing issues - honestly, I see more leaks from bad flashing than worn-out shingles. Using a flashlight after storms is smart, especially around chimneys and skylights. I’m with you on caulk not being enough long-term. I’ve seen people use flashing tape as an extra layer, but it really depends on how exposed that seam is and what kind of weather you get. Ever notice how some caulks just dry out and crack after a couple seasons? I lean toward metal flashing with a good overlap, then maybe tape if it’s a tricky spot. Curious if anyone’s had luck with those newer butyl tapes - seem stickier than the old stuff.

Flashing is the sneaky culprit, for sure. I’ve lost count of how many times I’ve been called out for a “roof leak” and it’s just a tiny gap in the step flashing or a cracked bit of caulk around a vent. Folks get so focused on shingles, but if water’s got a path under the metal, it’ll find its way inside no matter how new your roof is.

I’m in the Midwest, so we get those wild freeze-thaw cycles. That’s where caulk really lets you down - one winter and it’s brittle as chalk. I used to trust the old black roofing cement, but after seeing it peel up after two seasons, I switched to metal flashing with a solid overlap and stainless screws. For weird spots - like where an old satellite dish left holes - I’ve tried that newer butyl tape you mentioned. Honestly, it sticks like crazy compared to the old stuff. The trick is making sure everything’s bone dry before you put it down... learned that the hard way when one patch peeled up after a rain.

One thing I will say: flashing tape is great as backup, but I wouldn’t trust it as the main defense in high-wind areas. Had a neighbor who tried to “tape over” some bad chimney flashing instead of replacing it - last spring storm, water was pouring in behind his drywall. Ended up costing him way more than if he’d just done metal from the start.

I get why people want quick fixes (who wants to mess with prying up shingles?), but every time I’ve cut corners on flashing, I’ve regretted it later. If you’re already up there with a flashlight after storms, might as well check those seams and tuck in some fresh metal if anything looks sketchy.

And yeah, those new butyl tapes are miles ahead of what we had ten years ago... just don’t expect miracles if your base flashing is shot or installed wrong.

That’s a solid approach, honestly. I’ve seen way too many folks try to “seal” their way out of a flashing problem, and it just doesn’t hold up, especially with wild weather swings. You nailed it - metal flashing with a good overlap is way more reliable than any tape or caulk. I do wonder, though, if anyone’s tried recycled metal for flashing? I’m always curious about greener options, but sometimes the tried-and-true just works better. Either way, your method of checking after storms and not skipping the hard parts is spot on.

- Seen a few folks in my neighborhood try recycled aluminum flashing. Mixed results, honestly.
- The metal itself holds up about the same, but watch for thinner gauge stuff - some of the “green” batches dent easy in hail (ask me how I know... yeah, that was a fun spring).
- If you can get your hands on recycled copper, that’s a win, but it’s pricey and harder to find.
- Most of the time, the overlap and install matter way more than what kind of metal you’re using. My buddy did his whole shed with old road sign scraps - works fine, just looks like a traffic violation waiting to happen.
- I still lean toward whatever keeps stuff out of the landfill, but sometimes you gotta weigh that against doing the job twice.
- Regular checkups are clutch either way. I found a squirrel nest under my last flashing - little guy was living better than me for a while.

Anyone else notice recycled flashing seems to have more sharp edges? Or am I just clumsy?

Sharp edges on recycled flashing? Not just you. I’ve sliced my gloves (and a finger or two) more than once dealing with the stuff, especially when it’s been cut down from larger sheets or repurposed from something else. Seems like the recycled batches don’t always get deburred as well as the new stock, or maybe it’s just that the metal’s already been through a few lives and has more nicks and burrs to start with.

Here’s how I handle it now, after learning the hard way:

1. I always run a gloved hand along the edge before installing - if it catches, I hit it with a file or some sandpaper. Takes an extra minute but saves on band-aids.
2. If you’re cutting recycled flashing yourself, use tin snips instead of a saw whenever possible. Saws leave rougher edges.
3. For anything going up where folks might be working later (gutters, low rooflines), I’ll sometimes fold the edge over with pliers to blunt it out.

I’m all for keeping stuff out of the landfill, but I’ve noticed some of the “eco” aluminum is thinner than what you’d get new - especially if it’s from cans or lightweight siding. That’s fine for sheds or chicken coops, but on a main house roof in hail country? I’d rather not risk it unless I know exactly what gauge I’m getting.

On install - couldn’t agree more that overlap and fastening matter more than what kind of metal you’re using. Seen plenty of “premium” flashing leak because someone cheaped out on nails or didn’t tuck it right under the shingles.

And yeah, regular checkups are huge. Last fall I found a wasp nest tucked behind a piece of loose flashing - wouldn’t have known until they started coming inside if I hadn’t gone up there to check after a windstorm.

Bottom line: recycled is great if you’re careful about thickness and edges, but don’t skip the prep work or you’ll pay for it later (sometimes in blood).

That’s exactly why I make myself get up there twice a year, even though heights aren’t my thing. Missed a cracked vent boot once and it cost me drywall repairs in the bathroom. Recycled flashing’s a mixed bag for me too - sometimes you score, sometimes it’s so thin it feels like foil. The prep is annoying but way better than dealing with leaks or surprise stings...

I hear you on the recycled flashing - sometimes it feels like you’re just asking for trouble if it’s too flimsy. I’ve had a couple pieces that looked solid but bent up like a soda can the second I tried to nail them down. Still, I’d rather deal with that than pay for all new stuff every time, especially with prices lately.

Twice-a-year checks are a must in my book, even if it’s just to catch the little things before they snowball. Last spring, I found a squirrel had chewed through some old caulk around my chimney. If I hadn’t caught it, water would’ve been pouring in by summer storms. The hassle of hauling out the ladder beats drywall repairs or pest control bills any day.

I get why people put it off - heights aren’t fun and it’s easy to forget when nothing looks wrong from the ground. But honestly, a half hour up there can save hundreds later. Just wish someone had told me that before my first big leak...

That squirrel story hits close to home - last fall I found a bird’s nest wedged right under my ridge vent. Didn’t even notice until I heard scratching in the attic one morning. Turns out, they’d pecked away at the old sealant and left a nice little gap for rain to sneak in. Had to patch it up before the first big storm rolled through.

I get what you mean about recycled flashing. Sometimes it’s a gamble - if it’s too thin, you’re just asking for headaches later. I’ve started keeping a stash of offcuts from other projects, but if something looks sketchy, I’d rather spend a few extra bucks than risk water damage. Prices are rough, but mold remediation is worse.

Honestly, climbing up there twice a year feels like a chore, but every time I find something small before it turns into a disaster, I’m glad I did it. Heights aren’t my favorite either, but after dealing with one ceiling collapse (thanks to an ice dam), I’ll take the ladder over the shop-vac any day.

That’s exactly it - catching those little things before they turn into a nightmare is worth every bit of hassle. I’ve had to deal with critters too, and honestly, the damage they can do in just a few weeks is wild. I’m with you on the flashing - if it looks flimsy or sketchy, I just don’t trust it. Spending a bit more upfront has saved me from way bigger headaches down the line. Heights aren’t my favorite either, but after patching a leak in February (never again), I’ll take a fall check any day.

That February leak sounds rough. I had a homeowner call me out last spring because squirrels chewed right through some old flashing - water was pouring into the attic by the time I got there. The funny part? The “cheap fix” from two years earlier ended up costing triple in repairs. I always say, if the flashing looks like it belongs on a soda can, it probably won’t survive a storm or a hungry critter. Sometimes I think the real pests are the shortcuts we try to take...

Yeah, shortcuts always come back to bite you. I’ve seen folks use that thin, shiny flashing and think it’ll hold up, but one good storm or a determined squirrel and it’s game over. I get wanting to save money, but sometimes it just isn’t worth the headache later. I’m still learning, but every time I see a “quick fix” fail, it makes me double-check my own work... probably for the best.

That’s a good point about “quick fixes” - they’re tempting, but rarely hold up over time. I ran into something similar when I bought my place last year. The inspector flagged some questionable caulking around a vent pipe, but it looked fine to me at first glance. Fast forward to the first heavy rain, and there was a slow drip right above the bathroom. Turns out, the previous owner had just smeared silicone over a cracked boot instead of replacing it. Cost me more to fix the ceiling than it would’ve to address the flashing properly.

I’m curious - has anyone had luck with the newer composite flashing materials? I’ve seen them advertised as more durable than traditional aluminum, but I’m not sure how they hold up in the long run, especially in areas with big temperature swings. I want to avoid another patch job, but also don’t want to over-engineer if it’s not necessary.

I’ve actually been down the composite flashing rabbit hole after a hailstorm last spring. My house is in the upper Midwest, so we get wild temp swings - minus 20 in winter, then 90s and humid in July. I was skeptical about the plastic-based stuff at first, but my roofer swore by it for tricky spots where metal tends to warp or pull away over time. We used it around a skylight that’s always been a headache, and so far (about 18 months in), no leaks or weird expansion issues.

One thing I noticed: installation really matters. The guy who did mine took his time with the overlaps and made sure everything was sealed up tight. I’ve heard from neighbors who had quick installs and ended up with gaps after a couple freeze-thaw cycles.

Curious if anyone’s tried those “eco” recycled rubber flashings? I saw them at the supply store but wasn’t sure if they’d hold up or just end up brittle after a few winters.

Rubber flashings, huh? I’ve seen those at the supply shop too, and honestly, I was tempted just because the packaging had a cartoon frog on it. But I did a little digging (and by that I mean I bugged my boss and watched a couple YouTube reviews). Here’s what I picked up:

Step 1: Check the label for temp ratings. Some of those recycled rubber flashings are rated for “all climates,” but when you read the fine print, they mean “all climates in California.” Midwest freeze-thaw is a whole different beast. The ones with higher EPDM content seem to stay flexible longer, but the cheaper ones can get stiff and start cracking after a couple winters.

Step 2: If you’re thinking about using them, make sure you get the right adhesive. I’ve seen a guy slap one on with regular roofing cement, and it peeled up after the first cold snap. The manufacturer usually has a specific goop they want you to use - don’t skip it, or you’ll be cursing in February.

Step 3: Overlap and seal like your life depends on it. Rubber’s forgiving, but if you stretch it too tight or don’t tuck it under the shingles right, water will find a way in. I learned that the hard way on a dormer last fall... nothing like a surprise drip on your forehead at 2am.

Honestly, I’m still partial to composite for weird spots, especially around skylights and chimneys. Metal’s great until it starts popping loose or rusting out, and rubber’s got potential but feels a bit experimental for our climate. If you do try it, maybe test it on a less critical spot first - like a shed or garage - before trusting it over your living room.

And yeah, totally agree about install making all the difference. I’ve seen “quick” jobs where the flashing looked fine in August, then by March it’s waving at you from under the shingles. Slow and steady wins the leak-free race... or at least keeps your socks dry.

That cartoon frog gets me every time too - marketing genius, honestly. You nailed it with the Midwest freeze-thaw. I tried a “universal” rubber flashing on my uncle’s garage last year, and by spring it looked like a potato chip. Composite’s been more forgiving for me, but I’m still tempted to experiment on my own shed just to see if I can outsmart the weather. Your step-by-step is spot on - especially about the adhesive. Skipping that is just asking for soggy socks.

Composite’s been more forgiving for me, but I’m still tempted to experiment on my own shed just to see if I can outsmart the weather.

I’ve had similar thoughts about experimenting, but honestly, the Midwest climate seems determined to win every time. My place came with asphalt shingles, and after last winter’s freeze-thaw cycles, I noticed a few spots where the granules were basically gone. I did a patch job with some leftover shingles and proper adhesive (definitely agree - skipping that step is just asking for trouble), but I’m not convinced it’ll hold up long-term.

Has anyone here tried those newer synthetic flashings or underlayments? I keep reading they’re supposed to handle expansion and contraction better than rubber or metal, but I haven’t seen much real-world feedback. Also curious if anyone’s tracked how different adhesives perform over a couple seasons - seems like some brands just don’t bond well once temps drop below freezing.

- Noticed this bit:

“I did a patch job with some leftover shingles and proper adhesive (definitely agree - skipping that step is just asking for trouble), but I’m not convinced it’ll hold up long-term.”

- Synthetic underlayments are solid in theory, but I’ve actually had mixed results. One install on a neighbor’s garage peeled up at the edges after two winters. Might’ve been installer error, but still... not bulletproof.

- As for adhesives, cold weather kills most of them unless they’re specifically rated for low temps. I’ve had better luck with butyl-based stuff than asphalt or tar, especially when things dip below 20°F.

- Honestly, sometimes I wonder if chasing the “newest” materials is worth it. Old-school felt and metal flashing aren’t perfect, but at least you know what to expect when they fail.

- Anyone else notice synthetic stuff can get weirdly brittle after a few years? Maybe it’s just me, but I’m starting to trust it less for anything exposed.

Just my two cents - sometimes “tried and true” beats “latest and greatest,” especially when the weather’s out to get you.

Couldn’t agree more - sometimes the classics just work. Midwest winters will humble even the fanciest underlayment. You did the right thing patching it up, and honestly, regular checkups are half the battle. Even pros get surprised by what the weather throws at us.

I get the appeal of sticking with what’s tried and true, but I’ve actually seen a lot of the newer synthetics hold up better after big storms - especially when it comes to wind-driven rain. Old-school felt does its job, but once it gets saturated or a seam lifts, you’re in trouble pretty quick. The newer stuff isn’t perfect and yeah, it can be pricey, but in some cases it’s bought folks a few extra years before leaks showed up. Midwest weather’s rough either way, though… nothing lasts forever up here.
