Thermal cams are a wild ride, aren’t they? I’ve had days where I’m convinced the thing’s just showing me where the neighbor’s cat took a nap, and other times it’s like finding buried treasure—except the treasure is soggy plywood. Had a job last spring, similar deal: cam flagged a big ol’ blob over the living room. Figured it was just the sun baking the shingles, but nope—turns out the bathroom vent was leaking warm, moist air right into the attic. Mold city.
But yeah, sometimes you’re chasing your tail. I’ve seen “hot spots” that turned out to be nothing but a squirrel nest or even just a pile of old insulation. The tech’s great for narrowing things down, but you still gotta get your hands dirty and poke around. I trust my gut more than any gadget, but I’ll admit, those sci-fi reports have saved my bacon more than once. Just gotta remember, it’s a tool—not a crystal ball.
That’s spot on—thermal imaging can be a real mixed bag. I’ve had it point out a “major leak” that was just an old bird’s nest heating up in the sun. Still, it’s caught things I never would’ve seen otherwise. You really do have to double-check everything, but when it works, it’s hard to beat.

I get what you’re saying, but I’m still not totally sold on thermal scans as the gold standard. They’re flashy, sure, but I’ve seen them misread green roofs more than once—plants and soil can throw off the readings big time. Sometimes old-fashioned moisture probes or even just pulling up a section tells you more. Not saying tech’s useless, just that it’s not always the magic bullet folks hope for.
Yeah, I’ve run into that with green roofs too—thermal scans look impressive on paper, but real life’s messier. We had a leak last spring, and the scan flagged a totally different spot than where water was actually seeping in. Ended up just pulling up some pavers and insulation to find the culprit. I still use the tech as a first pass, but I don’t trust it alone, especially with all the weird variables on older buildings. Sometimes you just need to get your hands dirty...
That’s exactly why I’m always a bit skeptical about relying just on thermal scans, especially with older roofs or anything with layers like green systems. Ever notice how moisture can travel sideways under insulation or membranes? Makes me wonder if anyone’s had better luck combining scans with, say, smoke testing or flood tests. Or is it just more hassle than it’s worth?
