Not saying they’re useless, but you still gotta get up there and look with your own eyes.
That’s exactly it. I had a scan done last fall and the report looked like a heat map from NASA, but when I crawled up there, half the “problem areas” were just where the attic insulation had slumped. Still, I’d rather have a false alarm than miss a real leak. Curious—has anyone had thermal actually catch something serious that you couldn’t see from inside or outside?
Had a similar experience with thermal scans—looked like my roof was about to launch into orbit, but it was just old insulation and a squirrel nest. That said, one time it did flag a weird hot spot that turned out to be a slow leak under a vent. Wouldn’t have caught it until the next rain, so I guess it’s not all sci-fi nonsense. Still, nothing beats actually poking around up there yourself.
I get the appeal of climbing up there and checking things out yourself—nothing like getting your hands dirty to really know what’s going on. But honestly, I’ve seen way too many issues missed by just poking around, especially with older roofs or weird attic layouts. Those thermal scans might look a bit over-the-top, but they can pick up stuff you’d never spot with the naked eye, especially moisture hiding under layers or insulation gaps that aren’t obvious until you’re dealing with a drafty house.
Had a client last year who swore by the “old school” method—walked the roof every spring. Still missed a slow leak that was only visible as a faint heat signature on a scan. By the time it showed up inside, it was mold city behind the drywall. Not saying tech is perfect (false alarms from critters or old insulation are real), but I’d rather have one extra tool in the kit than rely on just what I can see or touch.
Guess it comes down to how much risk you’re willing to take. For me, if there’s a gadget that helps catch something early—even if it feels a bit sci-fi—I’m all for it.
I get where you’re coming from with the fancy scans and all, but man, I gotta say—sometimes it feels like these new gadgets are just another way to make my wallet cry. I had a guy quote me for a “full thermal imaging package” last year when I was just trying to figure out if my 90s asphalt shingles were still hanging in there. The price tag for the scan alone was almost what I paid for my last car battery. Maybe I’m just old-fashioned (or cheap), but I’d rather spend that cash on actual repairs than a sci-fi PDF that tells me what *might* be wrong.
Not saying the tech’s useless—sure, it probably catches stuff you can’t see. But in my experience, half the time it’s just telling me my attic’s hot (no kidding, it’s July in Texas) or that a raccoon’s been squatting up there again. I get the risk thing, but I’d rather take my chances with a flashlight and a ladder first, especially when every “extra tool” seems to come with an extra bill.
Had a neighbor who went all-in on the high-tech inspection route. They flagged a “potential moisture anomaly” that turned out to be an old Gatorade spill from when his kid used the attic as a secret hangout. He still jokes about the $300 “leak” he fixed with a mop.
I guess if you’ve got a complicated roof or you’re flipping houses, maybe it makes sense. But for regular folks like me, sometimes the old-school way (plus a little common sense and maybe a friend who owes you a favor) is good enough. If it ain’t broke, don’t scan it… or at least not until you’ve checked for the obvious stuff first.
I get where you’re coming from, but I’ve seen thermal scans save folks a ton of headache (and money) down the line, especially with older roofs. Yeah, the price can sting—no arguing there—but sometimes that “sci-fi PDF” actually points out stuff you’d never catch with a flashlight. Had a job last fall where the homeowner swore everything was fine, just a couple missing shingles. Scan picked up a hidden leak that had been slowly rotting the decking for who knows how long. If we’d waited until it showed on the ceiling, he’d have been looking at way more than the cost of the scan.
I’m not saying everyone needs to go full Star Trek every time something creaks up there. But in spots where water sneaks in or insulation’s weird, those gadgets can be worth their weight. I still do the old-school crawl myself half the time, but I don’t write off the tech either. Sometimes it’s just about picking your battles—if your roof’s simple and you know what to look for, sure, save your cash. But if you’re not sure? That scan might be cheaper than a surprise re-decking job...
