I hear you on the 7/12 pitch - mine’s not quite that steep, but it’s enough to make me question my life choices every time I haul the ladder out. Midwest winters just chew up anything rubber, and I’ve noticed the same thing: vent boots seem to go brittle and crack way before the shingles even start curling. I’ve tried both the standard rubber and the pricier silicone versions. Honestly, the silicone ones seem to last a bit longer, but they’re not invincible. After about five years, even those start to show some wear around the base, especially with all the ice dams we get.

One thing I’ve started doing is adding a little bead of roofing sealant where the boot meets the pipe - nothing fancy, just a cheap insurance policy. It seems to help, but I’m not convinced it’s a permanent fix. Still, paying $25 for a new boot and risking a sore back beats shelling out for a roofer every time. Not exactly my idea of a fun weekend, but it’s hard to argue with the savings.

- Totally get where you’re coming from on the pitch and the Midwest winters. That combo is brutal - makes me wonder why vent boots aren’t just made out of whatever they use for car tires.

- I’ve had the same experience:

“vent boots seem to go brittle and crack way before the shingles even start curling.”
Couldn’t agree more. I’ve swapped out the “lifetime” rubber ones and the silicone ones, and honestly, neither lasted as long as I hoped. Silicone’s a bit better, but not by much once you factor in ice and UV.

- Tried the sealant trick too. Helps for a while but, like you said, it’s not a forever fix. Still, I’d rather slap some goop on there every year or two than pay someone $200+ for a five-minute job.

- My neighbor swears by those “retrofit” covers that slip over the old boots. I’m skeptical, but he hasn’t had a leak yet. Might be worth a shot if you get tired of climbing up there.

- Hard to avoid the hassle if you want to keep things dry - just part of owning a house up here, I guess. At least swapping out boots is cheaper than fixing ceiling stains…

Yeah, you nailed it - those “lifetime” boots are anything but. I’ve had to replace mine twice in about ten years, and that’s with regular sealant touch-ups. The retrofit covers are actually not a bad idea if you’re over climbing ladders every spring. Not perfect, but definitely less hassle than tearing into shingles. Midwest winters just chew up everything on the roof, it seems.

I hear you on Midwest winters - mine trashed two sets of “lifetime” boots in less than a decade too. I switched to silicone retrofit covers last year, and while they’re not perfect, at least I’m not up there every season. Ever looked into metal vent boots or even green roof options? I’ve heard they hold up better in harsh climates, but I haven’t tried them myself yet.

Metal vent boots can definitely outlast the standard rubber ones, especially with the freeze/thaw cycles we get here. I’ve seen a few installations where the metal boots were still solid after 15+ years, though you’ve got to watch for rust if the flashing isn’t properly coated. Silicone covers are a decent stopgap, but they tend to degrade under UV after a while - nothing’s truly “lifetime” in Midwest weather. Green roofs are interesting, but unless your structure’s built for the load, they’re usually not practical just for vent protection. Honestly, I tell folks to check vent boots every fall - sometimes a $10 bead of sealant gets you another year.

I swapped my vent boots last fall after spotting a tiny leak in the attic - first time dealing with anything roof-related, and honestly, it was more nerve-wracking than I expected. I went with the metal boots because the rubber ones on my place were already cracking after just a few years (guessing the crazy temperature swings here don’t help). The metal ones weren’t cheap, but I figured it’s better than dealing with water stains or worse down the road.

One thing that surprised me was how much gunk builds up around those vents. I get the advice about checking every year - my neighbor’s been saying that for ages, and now I see why. I’m not convinced green roofs are worth it unless you’re planning a full reno. For me, spending a bit more upfront on the metal boots just felt like less hassle in the long run. Still, I keep a tube of sealant handy, just in case. Midwest weather finds a way to mess with everything eventually...

Yeah, I hear you on the metal boots. I swapped mine out a couple years back after the rubber ones basically turned to mush - didn’t even last five years with the wild temp swings here. Metal’s pricier, but I’d rather pay once than keep climbing up there every other season. The gunk buildup is real, too. I ended up pulling a bird’s nest out from under one vent last spring... never thought I’d be dealing with that. Midwest weather just loves to keep us on our toes.

That’s exactly why I switched to metal boots too. The rubber ones just can’t handle the freeze-thaw cycles - mine started cracking after a couple winters, and I got tired of patching them up. Metal was a bigger hit to the wallet up front, but honestly, not having to drag out the ladder every spring is worth it for me. Midwest weather is brutal on anything up there.

Funny you mention critters - I found a squirrel stash in one of my old vents last year. Never thought roof maintenance would turn into wildlife control, but here we are. It’s always something.

I get why some folks stick with rubber if they’re on a tight budget or planning to move soon, but for long-term peace of mind, metal just makes sense. Less hassle, fewer surprises... well, except for the occasional bird nest.

I get where you’re coming from, but I’m still a little skeptical about metal boots being the “set it and forget it” solution. Sure, they last longer, but I’ve seen some start rusting out after a few years - especially if you’re near any salt or industrial stuff in the air. Midwest weather is rough, but honestly, nothing’s truly maintenance-free up there. I do like that metal keeps the critters out better though... had a raccoon try to nest under my old rubber one and that was a whole saga. If only someone would invent a boot that’s both green and indestructible - now that’d be worth the hassle.

That’s a fair point about rust - coastal or industrial areas can eat through metal boots faster than folks expect. I usually recommend aluminum or stainless over galvanized for those spots, but even then, you’ve gotta keep an eye out. Midwest freeze-thaw cycles are brutal on all materials. Nothing’s truly “maintenance-free,” but metal does keep the raccoons and squirrels out better than rubber or plastic, for sure. I’ve seen some folks try those silicone boots lately - supposed to be more eco-friendly and flexible in the cold, but I’m not totally sold yet. Anyone else had luck with those?


Reply

I get the appeal of metal for critter-proofing, but honestly, the cost just doesn’t add up for me. I went with a heavy-duty rubber boot last time - yeah, it’s not perfect, but with a little sealant and checking it each fall, it’s held up fine through Michigan winters. Metal’s great if you want to set it and forget it, but if you’re willing to do a bit of maintenance, rubber or even those newer silicone ones seem like a solid budget option. I’d rather patch than replace the whole thing every few years.

That’s fair - if you’re willing to keep an eye on things, rubber or silicone boots can definitely stretch your dollar. I’ve patched mine a couple times and it’s still holding up. Metal’s nice, but not everyone wants to pay that upfront. Regular checks go a long way.

Metal’s nice, but not everyone wants to pay that upfront. Regular checks go a long way.

That’s pretty much where I landed too. When I bought my place last year, the inspector pointed out the vent boots were already showing age (I’ve got a 90s ranch with a low-ish slope and asphalt shingles, for reference). I priced out replacing them with metal, but honestly, after all the other move-in costs, I just couldn’t justify it right away.

Here’s what I ended up doing:
1. Checked the boots in early spring, since winter here (Ohio) is rough on rubber.
2. Noticed some minor cracking at the base - nothing catastrophic, but enough to worry about leaks once the snow melted.
3. Used a tube of roof sealant to patch the cracks and reinforced the seams. It took maybe 20 minutes per boot.
4. Set a reminder in my phone to check again before fall, since that’s when we get heavy rain.

This past winter, I did get a tiny drip in the attic - turned out the patch had started to peel. I replaced just that one boot with a silicone model (cost about $18), and so far, it’s holding up better than the original rubber.

Honestly, it’s not that much hassle if you’re comfortable getting up on a ladder and keeping an eye out for trouble spots. I get why folks go for metal, but if you’re willing to do a little maintenance, you can really stretch the life of the cheaper boots. Maybe not forever, but enough to spread out the expense.

One thing I wish I’d known: the flashing around the vent matters just as much as the boot itself. If it’s bent or not sitting flush, water will sneak in no matter what material you use. Next time I swap one out, I’m planning to check the whole assembly and maybe upgrade the flashing too.

Curious if anyone’s tried those “universal” retrofit boots? Saw them at the hardware store but wasn’t sure if they’re worth it or just a gimmick.

I’m right there with you on stretching out the life of the original boots. I’ve got a similar setup - mid-90s split-level, asphalt shingles, and a couple of vent boots that were already looking rough when we moved in. I priced out metal too, but the sticker shock was real, especially after all the other “new homeowner” surprises. Regular inspections and some targeted patching have kept things in check for me so far.

The point about flashing is spot on. I learned the hard way that even a brand-new boot won’t do much if the flashing’s warped or not tucked under the shingles right. Last fall, I noticed a small water stain in the guest room ceiling. Turned out the flashing had lifted just enough to let water wick under during heavy rain. I ended up pulling the shingles back and re-seating the flashing - tedious, but it solved the problem.

On the universal retrofit boots: I actually tried one last year when a boot split mid-winter and I didn’t want to mess with pulling shingles in the cold. It was one of those flexible silicone types that clamp around the pipe. Installation was straightforward, and it sealed up fine, but I did notice the fit wasn’t as snug as a proper replacement. It’s held up through a couple freeze-thaw cycles, but I’m keeping an eye on it. My guess is they’re a decent stopgap, but probably not a true long-term fix if your roof gets a lot of weather.

One thing I’d add - if you’re patching cracks with sealant, make sure to check for UV resistance. I used a generic caulk once and it started peeling after just one summer. Switched to a roofing-specific sealant and it’s lasted much longer.

All in all, I think it comes down to how comfortable you are getting up there and doing the checks. If you’re diligent, you can definitely buy yourself some time before shelling out for all-metal upgrades. But yeah, once the boots or flashing start to fail in multiple spots, it’s probably time to bite the bullet and do a full replacement.

Yeah, I hear you on the sticker shock for metal boots - felt like highway robbery when I priced them out last spring. I’m still running with the original rubber ones on my ‘98 ranch, and they’re definitely showing their age. I’ve patched a couple splits with that black roof sealant (the kind that smells like death and sticks to everything), but honestly, it’s just buying me time.

I tried one of those retrofit silicone sleeves too. It worked okay for a season, but after a rough winter, I noticed some seepage around the base. Maybe it’s fine in milder climates, but up here in Michigan, the freeze-thaw cycles seem to chew through anything that isn’t nailed down tight. I’m with you - good as a temporary fix, but not something I’d trust long-term.

Totally agree about flashing being the real culprit half the time. The boots get all the blame, but if the flashing’s bent or not tucked right, water finds its way in no matter what you do. I’ve started checking mine every fall before things ice up... not fun, but better than dealing with ceiling stains later.

- Metal boots are pricey, but I bit the bullet after my third patch job failed. Haven’t had a leak since, so maybe worth it in the long run.
- Rubber ones just don’t hold up here (I’m in northern Ohio, so similar winters). I got tired of climbing up every spring.
- Flashing’s a pain - mine was bent from a branch last year and that’s when the real trouble started. Took me forever to figure out it wasn’t the boot.
- If you’re on a budget, I’d say patch for now, but save up for metal. Swapping every season just isn’t worth the hassle or risk, at least for me.

Swapping out vent boots every season is one of those things that sounds manageable until you’re actually up there, year after year. I manage a few older duplexes in central Michigan, and the rubber boots just don’t cut it with the freeze-thaw cycles we get. I used to patch them with silicone or replace the rubber sleeves, but it always felt like a temporary fix. The tenants would call about leaks around the bathroom vent, and sure enough, it was the boot splitting or pulling away from the pipe.

I finally switched to metal boots on two of the buildings after a particularly rough winter - ice dams everywhere, and the rubber just couldn’t keep up. The upfront cost was a bit of a shock, but honestly, I haven’t had to touch them since. No more emergency calls in March when everything starts melting. I do think it’s worth it if you’re planning to stay in the house or keep the property for a while. The labor alone adds up if you’re paying someone to go up there every spring.

That said, I get why people stick with rubber if money’s tight. Metal boots aren’t cheap, and if you’ve got a low-slope roof or easy access, maybe patching is fine for a while. But on steep roofs or if you’re not comfortable climbing, it’s just not worth the risk. I’ve seen folks try those “universal” repair sleeves too, but they never seem to seal as well as advertised, especially once the sun bakes them for a season.

Flashing is another headache. One of my properties had a branch come down and bend the flashing just enough to let water in, but it took me ages to spot because the leak showed up in a totally different spot inside. Sometimes it’s not even the boot itself, but the way everything fits together. I’ve started checking the flashing every fall now, just to be safe.

If you can swing it, metal boots are a solid investment. If not, at least keep an eye on things after big storms or heavy snow. It’s amazing how fast a small split can turn into a ceiling stain...

Yeah, patching those rubber boots gets old fast. I tried using recycled EPDM boots a few years back, thinking they’d hold up better, but Michigan winters just ate them alive. Ended up with leaks in the attic insulation - what a mess to clean up. Switched to metal and haven’t looked back, but I do wish there were more eco-friendly options that actually last. Still, checking flashing every fall is smart... it’s always the little stuff that sneaks up after a storm.

I hear you on the eco-friendly front. Tried those “green” boots myself - didn’t even make it through two winters here in Wisconsin before they cracked. Metal’s been solid, but it does feel like a compromise. Ever looked into silicone boots? I read they hold up better in freeze-thaw cycles, but I haven’t tried them yet. Curious if anyone’s had luck with those or if it’s just more hype.

Silicone boots are actually pretty decent in the Midwest freeze-thaw circus - seen fewer splits compared to rubber, and they flex better when temps swing. Only catch is, squirrels seem to love gnawing on them for some reason... Not sure if that’s “eco-friendly,” but it’s definitely “eco-involved.”
