Nail pops are sneaky—I had one right above a bathroom vent that took me weeks to trace. Pulled half the ceiling down before I found it, and by then the insulation was a mess. I totally get the skepticism about metal roofs. They’re supposed to last, but if you don’t have the right underlayment or ventilation, you’re trading one headache for another. Honestly, stains and musty smells have led me to more leaks than any fancy moisture meter ever did... Sometimes it’s just about following your nose and gut.
Chasing leaks is a nightmare, especially with older buildings. I’ve seen water travel 10 feet from the actual entry point before showing up as a stain—drives me nuts. Metal roofs are great if installed right, but you’re spot on about underlayment and venting. I trust my nose more than any gadget too... If you’re dealing with musty smells, check for hidden insulation damage. Sometimes it’s not even the roof—it’s condensation from bad airflow.
Interesting point about trusting your nose over gadgets—though I’ve actually found moisture meters can pick up hidden damp spots that don’t smell yet, especially in wall cavities or under floors. Have you ever tried tracing a leak with an infrared camera? Sometimes the cold spots show up before any staining or odor. I get what you mean about airflow, but in my experience, a lot of “condensation” issues are actually slow leaks that just haven’t shown themselves clearly. Ever had a case where you thought it was condensation but it turned out to be a tiny flashing gap? Those drive me nuts.

Oh man, I’ve been there. Thought I had a humidity problem in the back bedroom for months—kept running the dehumidifier, even tried those little moisture absorbers. Turned out it was a hairline crack in the window flashing, just enough to let rain sneak in. Never would’ve found it without borrowing a buddy’s thermal camera. I still trust my nose, but those gadgets have saved me some serious drywall headaches. Funny how the “simple” issues end up being the trickiest.

That’s the truth. I spent a whole winter blaming my basement mustiness on poor ventilation, only to find out there was a pinhole leak right where the siding meets the foundation. It was so tiny, I almost missed it even when I knew what to look for. Sometimes I wonder if chasing leaks is just part of owning an older house... or if they’re just smarter than us.
