One thing I’ll say—sometimes less really is more with roofs. Every extra vent or cut is another thing to maintain or worry about down the line. I’d rather spend an extra hour double-checking what’s already there than add something new unless it’s really needed.
I get where you’re coming from, and I’ve definitely seen my share of “creative” venting jobs that caused more trouble than they solved. But I’ll throw in a slightly different angle—sometimes, especially on older homes, the original venting just isn’t up to snuff for today’s insulation and HVAC setups. I’ve been called out to fix ice damming or crazy attic heat, and after poking around, it was clear the house just couldn’t breathe with what it had. In those cases, adding a ridge vent or even a couple of well-placed box vents made all the difference. Sure, every hole is a risk, but sometimes the risk of not cutting is bigger.
Corners on metal edging are notorious, though. I learned the hard way early on—one job, we thought we’d done everything right, but a single missed dab of sealant at a corner led to months of mystery leaks. Customer kept calling back, swearing it was coming from somewhere else. Ended up crawling around the attic with a flashlight during a rainstorm (not my favorite memory) before finally tracing it to that one spot. Now I’m borderline obsessive about corners and overlaps.
I do agree with you about folks jumping straight to solar fans or fancy gadgets before checking the basics. Had a guy last year who swore his attic needed powered ventilation because “it’s just too hot.” Turned out his soffit vents were painted shut and his insulation was blocking half of what was left. Fixed that and he never mentioned the fan again.
Guess my point is, sometimes less is more—but sometimes you really do need to add something new, as long as you’re careful about how you do it. It’s always a balancing act between keeping things simple and making sure the roof actually works for how people live now.

That’s pretty much the heart of it. I’ve seen both sides—guys who want to cut a new hole for every little thing, and others who refuse to touch what’s there even when it’s clearly not working. I lean toward “fix what’s broken, don’t create new problems,” but like you said, sometimes the old setup just can’t keep up.
I’m with you on the venting. My uncle’s place is a 1950s ranch, and when he beefed up the attic insulation, suddenly he had condensation and mold issues he’d never seen before. The original vents were barely more than decorative at that point. We ended up adding a ridge vent and a couple of extra soffit vents, and it made a world of difference. But yeah, every time you cut into a roof, you’re rolling the dice a little. I get why people hesitate.
Corners and overlaps on metal are a nightmare if you’re not meticulous. I’ve had those “mystery leak” calls too—spent hours chasing water trails that ended up being a pinhole or a missed sealant bead. Now I double up on sealant at every joint, even if it feels like overkill. It’s always the spot you think is fine that comes back to bite you.
And the solar fan thing... I swear, half the time it’s just a band-aid for blocked soffits or insulation stuffed right up to the eaves. People want a gadget to fix what’s really just basic airflow. I’ve had to talk more than one homeowner out of spending money on powered fans when all they needed was to clear out the old insulation and open up the vents.
I guess what I’m saying is, there’s no one-size-fits-all answer. Sometimes you need to add, sometimes you need to just fix what’s there, but either way, you’ve got to pay attention to the details—especially on metal. One lazy corner and you’re back up there in the rain, cursing yourself.
Funny you mention the solar fans—I almost went down that road myself when I first noticed the attic getting stuffy. Ended up just clearing out the old insulation blocking the soffits and it made a bigger difference than I expected. I’m curious, though—has anyone tried those vented closure strips under metal panels? I keep hearing mixed things about whether they help with airflow or just let in more bugs and dust.

Clearing out the soffits made a huge difference for me too. As for the vented closure strips, I did install them last summer on my shed roof. Here’s what I noticed:
1. Airflow definitely improved, but it wasn’t dramatic—more like it helped keep temps a bit steadier.
2. Bugs? Yeah, a few more got in than before, even with the mesh. Mostly tiny ones, nothing major, but if you’re picky about that stuff it might bug you (no pun intended).
3. Dust was about the same as before.
If you’re in a windy or dusty area, you might want to weigh that against the extra ventilation. For me, the trade-off was worth it since my attic used to get pretty swampy in July.

That’s pretty much where I landed too. I put vented closures on my workshop and yeah, airflow was better, but I did end up sweeping out a few more dead bugs than before. Still, beats having the place turn into a sauna every summer. If you can live with a couple of gnats, it’s not a bad trade.
