That’s wild about the insulation blocking vents—I almost did the same thing when we moved in last fall. I was so focused on stuffing every gap, I didn’t realize I was making it harder for the attic to breathe. Our inspector pointed out the soffit vents and now I’m kind of obsessed with checking them. Still learning how all these pieces fit together… it really is like a weird puzzle sometimes. And yeah, those “fish scale” shingles are way more complicated than I expected.
Totally get what you mean about the attic vents—when I first started learning about roofs, I was surprised how much airflow matters. It’s easy to assume plugging every gap is good, but then you end up with moisture problems or even mold if the attic can’t breathe. I’ve seen a few places where insulation was packed right up against the soffits and it caused all sorts of headaches down the line.
And yeah, those shingles really do go on like fish scales. The overlapping pattern isn’t just for looks either—it’s all about keeping water moving down and off the roof. When you see how each row covers the nails from the row below, it starts to make sense why leaks happen if something’s off. Honestly, it took me a while to wrap my head around how precise you have to be with lining them up. One crooked shingle and it throws off the whole look (and sometimes function). Still blows my mind how much goes into something that just looks like a flat surface from the ground…
Yeah, lining up those shingles is way more important than it looks from the ground. I learned that the hard way after a windstorm peeled a few off—turned out the previous owner had a row or two just a bit off and water found its way underneath. Venting’s another thing folks overlook. I used to think more insulation was always better, but blocking those soffits just made the attic damp and musty. Now I check for airflow every time I’m up there. It’s wild how much you notice once you start looking for these details.
That’s spot on about venting—people get so focused on insulation, they forget the roof needs to breathe too. I’ve seen a lot of attics where folks stuffed every nook with insulation, thinking it’d help with energy bills, but then you get that musty smell and sometimes even mold. It’s wild how just a little blocked airflow can mess things up.
And yeah, shingle alignment is one of those things that looks simple but makes a huge difference. Even being off by half an inch can let water sneak in, especially after a big storm. I’ve had to fix more than a few jobs where someone rushed through and didn’t pay attention to the pattern. Once you start noticing those details, it’s hard not to see them everywhere.
Honestly, sounds like you’re way ahead of most folks just by checking your attic and keeping an eye on things. Most people don’t realize there’s an issue until water’s dripping through the ceiling... You’re doing it right by staying on top of it.

That’s the part that always gets me—people think more insulation is always better, but if you choke off the soffit vents or cover the ridge vent, you’re just asking for trouble. I had a neighbor who packed his attic so tight with fiberglass batts that he basically turned it into a greenhouse. Next summer, he was dealing with warped sheathing and a weird mildew smell that wouldn’t go away. Ended up having to pull out half the insulation and install baffles just to get some air moving again.
On the shingle alignment, I totally agree it’s not as simple as it looks. I’ve done a couple of small repairs myself, and even with a chalk line, it’s easy to get off track if you’re not paying attention. The “fish scale” pattern is there for a reason—if you don’t stagger them right, you end up with those straight lines where water can sneak in. I’ve seen some DIY jobs where folks just lined them up like bricks, and after one winter, you could see the water stains in the attic.
One thing I’d add—sometimes people forget about the underlayment too. Even if your shingles are perfect, if the felt or synthetic layer underneath isn’t installed right (or gets torn up during install), you’re still at risk for leaks. I had a roofer try to talk me into skipping ice & water shield on the eaves because “it never snows much here,” but after that freak ice storm a few years back, I was glad I insisted.
Curious if anyone’s tried those newer synthetic underlayments? I’ve only ever used felt, but I keep hearing they’re lighter and last longer. Not sure if it’s worth the extra cost or just marketing hype.
And yeah, keeping an eye on things is half the battle. I do a quick attic check every spring and fall—just looking for daylight where it shouldn’t be or any signs of moisture. It’s not glamorous work, but it beats dealing with a ceiling collapse down the line...
