I get where you’re coming from, but I’d push back a bit on the idea that “roof needs to breathe” isn’t as important with newer setups. Even with modern materials, ventilation is still huge—especially if you’re thinking about energy efficiency or even going green down the line. I’ve seen plenty of newer roofs (asphalt and membrane both) where lack of airflow led to mold or warped decking, even when everything looked fine from the outside.
Honestly, I’d trust my nose and eyes too, but I wouldn’t skip checking vents or making sure insulation isn’t blocking airflow. Tools are handy, but if you’re thinking about upgrades later (like solar or a green roof), getting the basics right now saves a ton of headaches.

Totally agree here—ventilation’s still a biggie, even with all the fancy new materials. I’ve been called out after storms to check “new” roofs that looked perfect, only to find soggy insulation and mold hiding underneath. Quick tip: if your attic feels stuffy or you spot frost on the nails up there, it’s time to check those vents. Don’t just trust the outside look... learned that one the hard way.
Funny timing—I just crawled up into my attic last week because I noticed a weird musty smell after the snow melted. Sure enough, there was a patch of mold right above the bathroom vent. The shingles outside look brand new, but that didn’t matter much with all the trapped moisture. I used to think newer roofs were “set it and forget it,” but now I’m poking around up there every spring. Lesson learned: if your attic feels like a sauna, something’s probably off.
I get what you’re saying about checking every spring, but honestly, I think sometimes folks go a little overboard poking around up there. Not every attic needs a deep dive unless you’ve got signs like that smell or visible stains. I’ve seen people actually cause more damage crawling around when nothing was wrong in the first place. That said, bathroom vents are sneaky—if they’re not vented right outside, moisture just hangs out and causes trouble. New shingles look nice, but yeah, they don’t fix airflow issues.

That’s the part that always gets overlooked. I learned the hard way—put on a new roof a few years back, but ignored the attic vents. Ended up with condensation and mold anyway. Sometimes it’s not about how often you check, but what you’re actually looking for.
