"make sure you've got some roofing sealant handy; even if the kit says you don't need it"
Wish I'd read this sooner... learned that lesson the hard way when I installed mine. Ended up making an extra trip to the store mid-project. Definitely worth having sealant ready just in case.
Good point on the sealant, but honestly, if you're careful with your flashing and shingles, you shouldn't always need it. I've done a few installs without sealant—just took extra time to align everything properly and never had leaks. Sealant can degrade over time anyway, so relying on proper technique might be better long-term. But yeah... having some handy doesn't hurt for peace of mind.
Interesting perspective on skipping the sealant. I've been helping out on a few roofing jobs lately, and I remember one install where we debated this exact issue. The lead roofer insisted that proper flashing and shingle alignment would be enough, similar to what you're suggesting. We took extra care, measured twice, cut once—you know the drill—and everything looked solid.
But here's the thing: about six months later, we had to revisit that same roof because of a minor leak during heavy rain. Turns out, even with meticulous alignment, there was a tiny gap we missed around the flashing edge. It wasn't catastrophic or anything, but it was enough to cause some water intrusion over time. After that experience, the crew started using a small bead of sealant as an extra precautionary measure, especially around tricky areas like attic fans or vents.
I totally get your point about sealant degrading over time—it's definitely not a permanent fix. But from what I've seen so far, even the best technique can occasionally miss something subtle. Maybe it's just my limited experience talking here, but wouldn't it make sense to combine careful installation with a modest amount of sealant as insurance? I'm genuinely curious if others have had similar experiences or if our situation was just an unlucky fluke.
Either way, I appreciate hearing your take on it—gives me something to think about next time I'm up there wrestling with flashing and shingles...
"Turns out, even with meticulous alignment, there was a tiny gap we missed around the flashing edge."
Been there myself—more than once. Flashing and shingles alone are usually solid if done right, but I've seen storms push water into spots you'd never expect. Learned the hard way that a thin bead of sealant in tricky areas is worth the extra 10 mins. Not foolproof forever, sure...but beats climbing back up in heavy rain six months later.
Yep, sealant's a lifesaver. Had a similar issue installing a vent last summer—thought I nailed it, but a tiny gap let water sneak in during a heavy downpour. Ended up redoing the flashing and adding some roofing cement around the edges. It's held up fine since then, but lesson learned: always double-check those tricky spots, even if they look perfect at first glance.
