You're spot on about insulation being overlooked. Had a similar situation last year—homeowner was convinced ridge vents would solve everything. After climbing up there, turns out the insulation was packed down and damp in spots. Once they replaced it and sealed a few air leaks, the moisture issues cleared right up. Ventilation matters, sure, but it's surprising how often insulation is the hidden culprit. Good call bringing that up.

Couldn't agree more. Had a similar inspection recently—homeowner was dead set on upgrading to premium shingles, thinking it'd fix their attic moisture issues. But when I got up there, insulation was thin and unevenly distributed, with clear signs of condensation buildup. Explained that even the best roofing materials won't compensate for poor insulation and air sealing. Once they addressed those issues first, the difference was night and day...and saved them from overspending on unnecessary upgrades.
Interesting points here, and it makes me wonder—how do you accurately pinpoint whether it's insulation or ventilation causing the moisture buildup? I've seen cases where homeowners upgraded insulation but still had lingering issues because ventilation was overlooked. Is there a reliable way to diagnose this without trial and error or hiring a specialist every time? Seems like it could save a lot of headaches (and money) if there's a straightforward method...
Honestly, I've been down this rabbit hole myself—thought I nailed it with extra insulation, but nope, still had moisture issues. Turns out ventilation was the sneaky culprit. One trick I heard (haven't tried yet, so grain of salt here) is checking attic temps and humidity levels with a cheap hygrometer before and after tweaking vents. Anyone tried this DIY detective work, or am I just setting myself up for another weekend project gone wrong...?

Did exactly this at my brother's place last summer—worked surprisingly well. Took some tweaking (and a few choice words), but we pinpointed his moisture issue down to blocked soffit vents. Worth your time, IMO.
