Funny thing, I used to think a little discoloration in the attic was just old wood—turns out, it was a slow leak from a cracked vent boot. Didn’t notice until I got that musty smell after a rain. Now I poke around up there every spring, even if it means crawling over insulation and spiderwebs. Those shingle granules in the gutter are like breadcrumbs leading to trouble... ignore them and you’ll pay for it later.
Those attic stains can be sneaky. I used to think the same, just old wood or maybe some leftover dust from when the house was built. First time I climbed up there on my own, I spotted this dark patch near the chimney. Figured it was nothing, but after a couple heavy spring rains, I got that damp, earthy smell you mentioned. Ended up tracing it back to a cracked flashing around a vent—barely visible from outside, but water found its way in anyway.
Now every spring and fall, I do a quick check. I start with the gutters—if I see more shingle granules than usual, that’s my first red flag. Then I walk the perimeter looking for any shingles that look curled or loose. Sometimes it’s just one or two, but even those can let water sneak under if we get a windy rainstorm.
Attic inspection is always last because it’s honestly not my favorite—crawling through insulation and dodging spiderwebs isn’t fun. But I bring a flashlight and check around all the vents and chimneys for new stains or soft spots in the wood. If anything looks off, I’ll poke at it with a screwdriver to see if it’s spongy.
One thing I learned the hard way: don’t trust caulk alone to fix leaks around boots or flashing. Tried that my first year helping out on roofs... looked fine for a few months, then leaked worse after the next freeze-thaw cycle. Replacing the boot or flashing is usually worth the extra effort.
I’m in a colder climate (upper Midwest), so ice dams are another headache—sometimes you’ll find water stains nowhere near where the leak actually started because it travels along rafters. That took me forever to figure out.
It’s easy to put off roof checks until something goes wrong, but every time I’ve caught an issue early, it’s saved me way more hassle and money than waiting for a ceiling stain or worse. Still, even with regular checks, stuff slips through—roofs are just one of those things you never really “finish” maintaining.

Can definitely relate to this. I just moved into my first place last summer and honestly, roof stuff was at the very bottom of my list until I read a couple stories like yours. I always just assumed if something was wrong, I’d see it right away—like a big wet spot on the ceiling or something obvious. Nope. First cold snap, I noticed this weird musty smell in the upstairs hallway. Took me a while to even think to poke my head into the attic. Turns out there was a tiny patch of damp insulation around one of the vent pipes. Not even a stain yet, but it was enough to get me worried.
I’m in the Northeast, so we get a fair amount of snow and ice. I didn’t even know what an ice dam was before owning a house... now I’m paranoid every time the snow starts melting and refreezing. The way you mentioned water stains showing up far from where the leak started—that’s exactly what tripped me up. I was looking in all the wrong spots at first.
Totally agree about not trusting caulk for the long haul. The previous owner had tried to “fix” a couple things with what looked like half a tube of caulk. Looked fine until the first freeze, then it all cracked and pulled away. Ended up having to replace a vent boot myself (YouTube is a lifesaver), and it actually wasn’t as bad as I thought.
I still don’t love crawling around up there, but hearing how much hassle it saves in the long run is pretty motivating. Feels like one of those things you never really get ahead of, but at least I’m learning. Appreciate hearing from folks who’ve been through it—makes me feel a little less clueless when I’m up there with my flashlight and dust mask.
That musty smell is always the first sign for me too—never fails, it’s something subtle before you see any real damage. I’m in upstate NY and ice dams are a yearly headache. The first winter in my current place, I thought I was in the clear until I found a puddle in the attic, nowhere near the outside wall. Turns out, water had traveled along a rafter from a nail pop halfway across the roof. I’ve learned to check after every big thaw, even if it feels like overkill. And yeah, caulk is just a temporary band-aid—if you see it peeling or cracking, it’s usually hiding a bigger problem underneath.

That’s exactly what I’m worried about. I keep finding little spots where the caulk’s gone brittle, but I’m never sure if it’s worth calling someone in or just patching it myself for now. Has anyone tried those roof sealant tapes? I’m tempted since they’re cheaper than a pro, but not sure if they actually hold up through another winter. Also, does anyone else get nervous poking around in the attic after a thaw, or is that just me?
