Foolproof method? Not yet. Just layers of paranoia and experience, I guess.
That pretty much sums up how I feel tackling my own deck for the first time. I’ve tried the meter and poking around, but like you said, it’s not always reliable—especially near flashing or where water might pool. Pulled up a couple boards last weekend “just in case” and found some soft spots I never would’ve guessed were there. It’s a bit nerve-wracking, but hearing that even experienced folks don’t have a perfect system is honestly reassuring. Guess it’s just about being thorough and not skipping steps, even if it feels like overkill sometimes.
Funny how you can poke and prod all you want, but sometimes the worst spots are just invisible until you actually pull up a board. I’ve had decks that looked fine—solid when you walked on them, meter readings normal—but then you open up a seam near a valley or chimney and there’s rot hiding right underneath. It’s tedious, but I’d rather be a little paranoid and spend an extra hour now than have to go back and fix something after the underlayment’s down. If it feels like overkill, it probably means you’re doing it right.
Had a deck last year that looked like it could hold up a marching band—solid as a rock, or so I thought. Pulled up a couple boards near the skylight just to be thorough, and boom... found a patch of rot the size of a dinner plate. The rest of the crew thought I was being picky, but I’ve learned the hard way that water finds its way into places you’d never expect, especially around chimneys and valleys.
I get why some folks skip the extra checks, but honestly, I’d rather deal with a little eye-rolling from my team than have to explain to an owner why their brand new underlayment is bubbling up six months later. Sometimes it feels like overkill, but in my experience, paranoia pays off—at least when it comes to roofs. Plus, there’s something oddly satisfying about catching those hidden trouble spots before they turn into real headaches.
You’re spot on about water finding its way into the weirdest places. I’ve seen decks that looked perfect from the top, but once you start poking around—especially near penetrations like skylights or chimneys—it’s a different story. I get pushback too when I slow things down for extra checks, but I’d rather be the “paranoid” one than deal with callbacks or worse, mold complaints down the line.
Here’s how I usually break it down: First, I walk the whole deck and look for any soft spots or discoloration. Even if everything feels solid, I’ll still check around all the roof penetrations—skylights, vents, valleys, you name it. If there’s even a hint of water staining or a musty smell, I’ll pull up a couple boards. Sometimes it feels like overkill, but every time I’ve skipped this step to save time, it’s come back to bite me.
I know some folks just want to slap on underlayment and move on, especially if the schedule’s tight. But like you said, explaining to an owner why their new roof is bubbling or leaking is way worse than taking an extra hour upfront. Plus, once you’ve seen what hidden rot can do—especially in wetter climates—it’s hard to unsee it.
One thing I started doing is keeping a cheap moisture meter handy. Not perfect, but it helps spot trouble before you even pull boards up. And if there’s any doubt about a section, I’d rather replace a few feet of decking now than risk the whole job later.
It might feel like nitpicking to some crews, but in my experience, those “paranoid” checks are what separate a quick fix from a job that actually lasts. You’re not alone in being thorough—even if it means catching some side-eye from the team now and then.

Couldn’t agree more with this. The folks who roll their eyes at “overkill” are usually the same ones who end up with callbacks or warranty headaches. I’ve lost count of how many times I’ve found rot hiding right around a vent or skylight that looked totally fine from the surface. It’s wild how water will snake its way in, especially if you’re in a spot with freeze-thaw cycles or just a ton of rain.
I’ll admit, sometimes I get pushback too—guys want to move fast, especially if weather’s closing in. But like you said, explaining to a client why their “new” roof is leaking is a nightmare. I’d rather take the hit on time than reputation.
Moisture meters are underrated, honestly. Not perfect, but they’ve saved me from missing stuff more than once. And if you’re thinking long-term, especially with green or cool roofs, that extra diligence up front is non-negotiable. Once you’ve seen what trapped moisture does under a living roof system... yeah, you don’t forget it. Keep doing what you’re doing—your future self (and your clients) will thank you.
