I get the hype around silicone, but honestly, I’m still not sold on it being a magic bullet. Maybe it’s just my luck, but I’ve seen a couple of those newer silicone boots start to pull away after a nasty hailstorm—seems like nothing’s totally immune. For me, the real game changer was switching to metal retrofit flashing with a flexible collar. It’s not as “set it and forget it” as folks hope, but at least when the boot fails, you’re not tearing up shingles every time. Just my two cents from chasing leaks after every Midwest thunder-boomer...

Honestly, I get where you’re coming from. Silicone boots sound great on paper, but after a couple Midwest hailstorms, I’ve seen them split or peel too. Metal retrofit with a flexible collar isn’t perfect, but at least you can swap it out without wrecking half the roof. I’d rather deal with a little extra maintenance than chase leaks every spring. Sometimes “low maintenance” just means “harder to fix later,” you know?

That’s fair, but I’m still not totally convinced metal retrofit is always the way to go. I’ve seen a few of those collars get pretty chewed up after a couple years of freeze-thaw cycles, especially on steeper roofs. Maybe it’s just our weird weather up here, but sometimes the “easy to swap” part doesn’t work out so easy when everything’s warped or the old boot’s stuck under a ton of granules.
Honestly, I’ve had better luck with the thicker rubber boots, even if they’re not as flashy. They’re cheap and I can just slap a new one on every few years without much hassle. Maybe I’m just used to doing it the hard way, but tearing up a shingle or two isn’t the end of the world if it means a better seal.
Guess it depends how picky you are about maintenance vs. replacement. Either way, nothing’s really “set it and forget it” around here—stuff just doesn’t last like it should with these winters.

Totally get that. I swapped out a metal collar last spring and it was so warped from the cold I had to basically pry it off in pieces. Ended up going back to the heavy rubber boots too. Not glamorous, but at least I know what I’m dealing with when it’s time to swap again. These northern winters just chew through everything anyway...
Rubber boots might not win any beauty contests, but honestly, I’d rather deal with a cracked rubber boot than a rusted-out metal collar that’s fused to the pipe like some kind of wintertime sculpture. Up here, it’s all about picking your battles—nothing survives the freeze-thaw for long. At least with rubber, you know what you’re getting and it won’t shred your knuckles trying to swap it out. Sometimes “not glamorous” is just code for “actually works.”
