Yeah, ventilation's definitely something people underestimate. I've seen a few skylight installs where they skipped proper airflow checks, and sure enough, mold city. One thing I've found helpful is mapping out airflow paths beforehand—like literally sketching it out. Sounds tedious, but it helps catch potential dead zones early. Ever tried using ridge vents combined with soffit vents? Seems to keep things moving nicely...
I actually went with ridge and soffit vents on my last roof redo, and it made a noticeable difference. Before that, I had those box vents scattered around, and the attic was always stuffy and humid. After switching, you could literally feel the airflow improve. But I'm curious—do you think the type of roof support (rafters vs trusses) significantly affects how well ventilation setups perform? Seems like trusses might complicate airflow paths a bit...
"Seems like trusses might complicate airflow paths a bit..."
Yeah, you're onto something there. Trusses can definitely create more obstacles for airflow compared to rafters, especially if they're closely spaced or have lots of cross-bracing. But honestly, with proper ridge and soffit vents like you mentioned, it's usually not a huge issue. I've seen plenty of truss roofs ventilate just fine as long as the insulation isn't blocking airflow. Rafters might be simpler, but either setup can work well if done right...
"I've seen plenty of truss roofs ventilate just fine as long as the insulation isn't blocking airflow."
That's true, but I've also run into a few cases where trusses made things trickier. Had one job last summer where the insulation guys packed it in way too tight around the cross-bracing—ended up blocking half the soffit vents. Rafters might've prevented that headache. Still, if everyone's careful and checks the details, either way can work out fine. Just gotta keep an eye on the insulation crew...
Good points all around. I've noticed that trusses can sometimes make inspections tougher too—harder to spot insulation issues or leaks early. Ever had trouble catching problems early because of limited attic access with trusses?
