Swapping vent boots every season sounds like overkill to me, unless you’re dealing with some really old, brittle material or a roof that’s seen better days. I’ve inspected plenty of Midwest homes and honestly, most leaks I find around vent pipes are from boots that cracked slowly over years—not months. That said, those little splits can be sneaky. Had a place last fall where the attic looked bone-dry except for a faint patch behind a stack vent. Turned out the original rubber boot had just started to split on the sunny side and water was wicking in during heavy rain. No stains on the ceiling yet, but you could smell the mustiness.
Silicone or recycled rubber boots are definitely worth it if you’re replacing. They hold up way better against UV and temperature swings—plus, less junk heading to the landfill. I get why people want to “set it and forget it.” But honestly, even with the newer materials, I’d still check them every couple years, especially if your roof faces southwest or gets hammered by wind.
Climbing up there every season? Not unless you really love ladders or have nothing better to do on a Saturday morning. Most folks aren’t going to spot hairline cracks from ground level anyway. Binoculars help for a quick look, but sometimes you just need to get eyes on it up close.
I’d say: don’t stress about swapping boots with every season change, but don’t ignore them either—especially if your shingles are getting up there in age. A little time spent checking now beats dealing with insulation full of mold down the road... trust me on that one.
I’m with you—swapping vent boots every season seems like a lot, unless you’re dealing with a really old roof or some shoddy install work. I manage a few buildings with roofs pushing 25 years, and honestly, the only time we’ve had to swap boots more than once a decade was when a hailstorm trashed the whole area. Even then, it’s usually the older rubber ones that go first, especially on the south sides where the sun just cooks them.
I do wonder about those “lifetime” silicone boots though. Anyone actually seen them hold up for 20+ years? I’ve had mixed results—sometimes the flashing fails before the boot itself. Either way, I’d rather spend a few minutes every spring and fall just looking for trouble spots than climb up there four times a year. Moldy insulation is a nightmare to deal with... but swapping boots constantly? That’s just not practical for most folks.
I’m with you—changing boots every season just doesn’t add up, especially if you’re keeping an eye out for cracks or dry rot during regular checks. I’ve got a 17-year-old roof with the original silicone boots, and they’re still holding up, but the flashing around one vent started to rust out before the boot itself. Is it just me, or does flashing seem to be the weak link more often than not? I’d rather budget for a quality boot and flashing combo once every decade than mess with it every few months.
- Totally agree—flashing is usually the first thing to go, especially in spots that see a lot of water run-off or snow buildup.
- I see more leaks from rusted or poorly installed flashing than failed boots, honestly.
- If you’re in a wet climate, galvanized flashing just doesn’t last as long as people think.
- I’d rather pay for a solid combo up front too... patch jobs every year are just a pain and never seem to last.
Flashing failures are definitely the main culprit I see during inspections, especially on older roofs or where there’s a lot of freeze-thaw. Boots do crack eventually, but it’s usually the seams or rusty flashing that let water in first. Galvanized just doesn’t cut it long-term if you’re anywhere damp. I’ve seen folks swap boots every couple years and still end up with leaks because the flashing underneath was toast. Honestly, investing in good flashing and proper install from the start saves a ton of headaches down the road... patch jobs rarely hold up more than a season or two.
