That PDF sounds wild—I’ve seen some of those “thermal scan” reports that look like something out of a NASA briefing. But yeah, I’m with you on the old-school checks. I’ve tried a few of those smart sensors and leak detectors, and while they’re neat, nothing replaces crawling up there with a flashlight and poking around, especially after a Midwest freeze-thaw cycle.
Here’s my usual routine: every spring and fall, I grab a ladder, check the attic for any damp spots or weird smells (mold loves to sneak in), then get up on the roof to look for loose shingles or popped nails. If I spot a sketchy wire connection—especially around attic fans or old satellite dishes—I’ll twist on a fresh wire nut with a dab of dielectric grease. It’s not glamorous, but it’s saved me from more than one “surprise drip” during a thunderstorm.
Gadgets are fine, but if you’re not eyeballing things once in a while, you’re just asking for trouble... or at least a soggy ceiling tile.
Those thermal scans are impressive, but I’ve seen them miss stuff that’s obvious once you’re up there in person. I’m with you—nothing beats actually getting your hands dirty, especially after a rough winter. Curious, do you ever check the flashing around chimneys or vents when you’re up there? That’s where I see most leaks start, but a lot of folks overlook it.
Funny you mention the flashing—last spring I found a leak right where the vent pipe meets the roof. The scan didn’t pick it up at all, but once I peeled back a shingle, it was obvious. I get why people love the tech, but there’s just no substitute for crawling around up there and poking at things. Ever had issues with those rubber boots around vent pipes? Mine always seem to crack after a couple of winters.
That’s been my experience too. Those rubber boots just don’t seem to hold up, especially in places with big temp swings—mine started splitting after two winters. Here’s what I ended up doing: first, I checked for any visible cracks or dry rot. If there was even a small split, I’d cut away the old boot and slide a new one over the pipe, making sure it fit tight to the shingles. Sometimes I add a bead of roofing sealant around the base, just in case. Tech can help spot some stuff, but honestly, nothing beats getting hands-on. Those leaks hide in plain sight if you’re not looking close.

Fully agree there—no drone or infrared scan will ever replace crawling up there and poking around. I’ve had those high-tech reports flag “potential moisture intrusion” and it turned out to be nothing more than a bit of old caulk. Curious if anyone here has tried the metal retrofit boots? I swapped to those after the third rubber one failed. Seemed pricey at first, but they’ve held up through four winters now, even with our freeze-thaw cycles.
