Also, double-check ventilation; poor airflow can trap heat and moisture, undoing all your prep work. Learned that lesson myself a while back...
Did you prime and seal beforehand? Sometimes attic heat isn't the only culprit—I've seen paint peel even with decent ventilation if the prep was rushed. Learned that the hard way myself... prep's a pain, but skipping steps always comes back to bite.
Good point about prep work—seen that happen a few times myself. Do you think insulation type might play into this too? I've noticed certain insulation materials seem more prone to trapping moisture, even with decent airflow... had a client once whose attic was properly vented but still dealt with moisture buildup because of insulation choice. Curious if you've experienced anything similar.
Yeah, insulation type definitely matters. Had a similar issue once—client had spray foam insulation, and even though ventilation was spot-on, moisture kept building up. Switched to cellulose and problem solved. Sometimes the attic gods just like messing with us...
Interesting point about cellulose—I’ve seen similar results myself. Spray foam can sometimes trap moisture if the application isn't perfect, especially in colder climates. I've wondered if it's partly due to how foam seals everything so tightly that even minor imperfections in ventilation become magnified. Cellulose seems more forgiving in that sense, allowing moisture to dissipate gradually. Still, every attic seems to have its quirks... makes you wonder how much we really understand about airflow dynamics up there.
"Cellulose seems more forgiving in that sense, allowing moisture to dissipate gradually."
That's exactly my experience. Had a property once where spray foam was installed pretty aggressively—sealed tight as a drum. Looked great on paper, but come winter, we got condensation issues popping up everywhere. Switched back to cellulose, and things improved noticeably. But now I'm curious... has anyone experimented with mixing insulation types? Maybe foam around tricky spots and cellulose elsewhere? Wonder if that'd balance things out or just complicate matters further...
