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

Rubber just seems like candy to those little guys. It’s not a perfect fix, but it’s slowed down the damage for me. Have you tried layering materials or is that overkill?

That’s not overkill at all - honestly, I’d call it smart prevention. I went through three sets of rubber boots in five years before I finally caved and did the metal collar trick. I used a stainless steel shield from the plumbing aisle, slipped it under a thick silicone boot, and haven’t had any chew marks since. Squirrels are relentless, but they’re lazy when it comes to chewing through metal.

Some people think layering is too much, but with the price of water damage repairs these days, I’d rather be “overkill” than mopping up my attic every spring. If you’ve got a low-slope roof or lots of tree cover like I do, doubling up makes even more sense. One thing I’d add: check every year for tiny gaps where critters might sneak in - sometimes they’ll go around the collar and gnaw at the edges if they’re desperate.

It might feel like extra work upfront, but in my experience, it saves you way more time (and money) down the line.

Layering’s definitely not overkill, especially if you’ve ever seen what a persistent squirrel or raccoon can do in a single season. I used to think just swapping out the rubber boots every couple years was enough, but after last fall - when I found daylight shining through a chewed-out vent - I started doubling up too. I went with an aluminum storm collar under a silicone boot, and it’s held up way better so far.

One thing I’d toss in: sometimes those critters will start at the edge of the flashing where it meets the shingles, especially if there’s any gap or soft spot. I learned (the hard way) that a dab of roof cement around the base helps keep them from prying things up. It’s not perfect, but it slows them down.

I get why some folks say it’s overkill, but honestly, patching water stains on your ceiling is way more hassle than spending an extra hour on install. Especially if you’re in a spot with lots of trees or older homes nearby...those little guys are clever.

You nailed it about those critters - I've seen raccoons peel back flashing like they're opening a can of tuna. I used to think a single boot was fine too, but after patching the same leak twice in one year, I started doubling up with metal and silicone. Roof cement at the seams is a solid move, though I wish it lasted longer in our freeze-thaw cycles. Honestly, I'd rather spend an extra hour up there than deal with soggy drywall later.

Same here - learned the hard way that a little extra time up front saves a lot of cash. I tried just caulking, but our Minnesota winters cracked it fast. Swapping boots every couple years isn’t fun, but neither is replacing insulation...

- Totally get it - Minnesota winters are brutal on anything up there.
- I’ve tried the “just caulk it” route too... didn’t last a full season before it started leaking again.
- Swapping boots isn’t cheap, but neither is fixing water damage.
- Anyone else notice the price on those boots creeping up lately?
- Wondering if there’s a longer-lasting option that doesn’t break the bank.
- I’m tempted to try one of those “lifetime” silicone ones, but not sure if they’re worth the upfront cost.
- For now, I just keep a close eye every spring and fall - cheaper than a surprise repair bill.
