Swapping Out Roof Vent Boots With The Seasons - Worth The Hassle?

I get the urge to slap on a split gasket when it’s freezing out - nobody wants to be up there in January. But yeah, I’ve seen them crack or shift after a rough winter. If you can wait for warmer weather, swapping the whole boot just holds up better and keeps stuff out of the landfill. I always tell folks: one solid fix beats three quick patches... plus your roof (and wallet) will thank you later.

I totally get the temptation to just slap on a quick fix when it’s freezing - last winter, I tried patching a cracked boot with some tape and a prayer. It held for about two weeks before water started dripping into the attic. Lesson learned: waiting for spring and swapping the whole thing was way less stressful (and less messy). If you’re like me and want to avoid climbing up there twice, it’s worth holding out for better weather. Plus, those split gaskets never seem to line up right on my roof anyway...

If you’re like me and want to avoid climbing up there twice, it’s worth holding out for better weather.

I hear you on that - climbing up in the cold is just asking for trouble. I tried a “quick fix” with some roof cement in January once, and it was so stiff from the cold that it barely stuck. Ended up redoing the whole thing in April anyway. For me, waiting until spring means the shingles are more flexible and less likely to crack when you lift them.

One thing I’ve wondered: has anyone tried those all-rubber boots that claim to flex better in cold temps? My roof’s got a pretty steep pitch, so I’m always looking for ways to make the job safer and quicker. Also, curious if folks have had luck with the retrofit split boots long-term, or if they’re just a stopgap. I’ve only ever used them as a temporary patch, but maybe I’m missing something.

What kind of roof are you working with? Asphalt shingles here, and they get brittle fast once it drops below freezing...

I’m honestly not sold on those split boots for anything long-term. I put one on last fall when I spotted a leak, and it got me through the winter, but by spring it was already starting to curl up at the edges. Maybe it’s just the freeze-thaw cycles here (Midwest), but I wouldn’t trust it for more than a season or two. Has anyone actually had one last more than a year without issues? I keep hearing mixed things, and I’m not convinced they’re worth the extra cost over just doing a proper replacement when the weather’s decent.

I’m in the same boat, honestly. When I bought my place last year, the inspector flagged a cracked boot but said it “wasn’t urgent.” Fast forward to a rainy week and… surprise, water in the attic. I tried one of those split boots because I was nervous about pulling shingles as a newbie. It worked for a bit, but I noticed the edges lifting after just one season - maybe it’s our crazy freeze-thaw too (I’m in Wisconsin). Has anyone tried sealing the edges with extra caulk, or does that just buy you another few months? Wondering if I should just bite the bullet and do a full replacement next dry spell.
