I get the worry about roof upgrades making things more complicated, but honestly, I’d rather deal with a little extra hassle upfront than risk a big leak down the road. When I did my attic fan, I skipped the peel-and-stick and used a high-quality flashing kit with extra caulk. It took longer, but I felt better knowing it was solid, especially with all the freeze/thaw we get. Sometimes the “easy” route just isn’t worth the stress later.

I hear you, but I’ll admit—I went with peel-and-stick for my solar fan install last summer. We get a lot of wind-driven rain here, and so far, no leaks (knock on wood). Maybe I just got lucky, or maybe the roof gods were in a good mood that day... But yeah, I do wonder if I’ll regret not going the extra mile when winter really hits.
I get what you’re saying about the “easy” route sometimes coming back to bite you, but I’m not totally convinced peel-and-stick is always a bad call. I actually used a similar method for a small attic vent last fall—just followed the manufacturer’s instructions and made sure everything was pressed down tight. We had a few nasty storms this spring, and I checked the attic after each one... dry as a bone. Maybe it’s just luck, or maybe the newer adhesives are better than they used to be.
That said, I do spend more time than I’d like worrying about it. My house is only a few years old, so the shingles are still in good shape, which probably helps. If I had an older roof or lived somewhere with snow piling up, I might have gone for a more permanent install. But for now, fingers crossed it holds up through another winter. Sometimes it feels like there’s no perfect answer—just trade-offs depending on your roof and your nerves.
I hear you about the trade-offs. I’ve seen peel-and-stick hold up surprisingly well on newer roofs, especially when the shingles are still flexible and the surface is clean. But I’ve also seen cases where a little bit of grit or old sealant underneath can mess with the adhesion over time. Out of curiosity, did you do anything special to prep the area before sticking it down? Sometimes even a quick wipe-down makes a difference, but I know not everyone bothers.
I’d actually push back a little on how well peel-and-stick holds up, even on newer roofs. If there’s any residual granule loss or micro-cracks in the shingle surface, adhesion can get spotty—especially after a season or two of freeze-thaw cycles. I’ve seen “just a quick wipe-down” (
) help, but sometimes it’s not enough if the surface isn’t truly clean or dry. I usually recommend a careful inspection and, where possible, a primer—especially for older or weathered shingles. Might be overkill for some, but it’s saved headaches down the line in my experience.Sometimes even a quick wipe-down makes a difference...
