You nailed it about the transitions—those are always where I get nervous, too. Flashing gets all the blame, but honestly, it’s those weird spots where two materials meet that seem to let water sneak in. I’ve seen more problems at parapet walls and skylight edges than anywhere else. Even with a solid membrane, if you don’t detail those connections right, you’re just asking for trouble.
I went back and forth on whether to splurge for a root barrier layer or not. Ended up adding it after hearing a horror story from a neighbor—roots found a seam and started working their way into the insulation. That was enough for me. The upfront cost stings, but like you said, fixing leaks or rot later is way worse (and pricier).
I still check mine after every heavy rain too... probably overkill, but I just don’t trust water to behave. Plants are easy to replace if they fail, but once moisture gets in under everything, it’s game over for your roof deck.

Couldn’t agree more. I thought I was being super careful with my skylight curb, but a year in, I found a tiny leak right at the corner where the membrane met the flashing. Had to pull up a chunk of sedum just to fix it. Now I’m borderline paranoid about every seam and edge—definitely not overkill to check after storms. Water always finds the one spot you missed.
That’s the thing—water’s sneaky. I’ve seen folks do everything by the book, but one missed bead of sealant or a slightly off corner, and you’re chasing leaks for months. I get the paranoia, honestly. After a hailstorm a few years back, I started checking every seam with a flashlight. It’s a pain, but it beats tearing up plants later. Those curb details around skylights are notorious for trouble... you’re not alone there.
I get the urge to check every seam, but honestly, I think there’s a point where you can overdo it. I spent hours with a flashlight after my install, convinced I’d missed something, but in the end, the real issue was actually poor drainage—not a missed bead of sealant. For me, focusing on the slope and making sure water moves away from skylights and curbs made more difference than obsessing over every tiny gap. Sometimes it’s less about paranoia and more about the big picture... at least that’s how it played out for me.
- Totally get this. I used to stress over every little seam too, but honestly, the drainage setup ended up being my main headache.
- For my install, I focused on making sure the slope was right and the drains weren’t blocked. That’s what actually saved me money on repairs later.
- Not saying ignore the seams—just don’t lose sleep over tiny stuff if your water flow isn’t sorted.
- One thing I learned: cheaping out on drainage layers cost me more in the long run... wish I’d just spent a bit more up front.
