- Totally get what you’re saying about the musty smell. Nine times out of ten, that’s the first thing I notice too—especially in older buildings or spots that don’t get much airflow. It’s wild how your nose can pick up on stuff before any gadget does.
- Walking the roof after storms is key, but I’d add: don’t just look for obvious puddles or stains. I’ve found trouble spots just by noticing a slight dip or even a patch that feels “off” underfoot. Flat roofs especially love to hide problems until they’re big.
- I do agree with the once-a-year pro check, but honestly, in places with heavy snow or wind (I’m up in the Midwest), I’d say twice a year isn’t overkill—spring and fall. Had a client who thought annual checks were enough, but ice dams snuck up on him last February and made a mess.
- For folks with lots of rooftop equipment (HVAC, solar panels, etc.), watch out for spots around mounts and brackets. Those little penetrations are leak magnets if the sealant dries out. Sometimes you’ll see a tiny crack and think it’s nothing... then months later, you’re dealing with soggy insulation.
- Moisture meters are handy but not foolproof. I’ve had them give me a false sense of security more than once, especially if the insulation underneath is already saturated but the surface is dry.
- One thing I always mention: document what you see. Take photos, jot down dates, even if it’s just minor stuff like a popped nail or loose flashing. Makes life way easier if you ever need to file an insurance claim or show a contractor what’s changed over time.
- Not everyone wants to climb up there (understandable), but even just walking the perimeter from the ground and looking for new stains inside can catch a lot.
- Last thought—if your roof is getting up there in age (15+ years), inspections become more important. Small issues multiply fast as materials start to break down.
Hope that helps someone avoid a nasty surprise... nothing like finding a leak right above your desk on a Monday morning.
Totally agree about the musty smell being a dead giveaway—my place is only 12 years old but I still catch that sometimes after a wet week. Curious, has anyone actually found leaks just from that? I’ve always wondered if it’s worth investing in those moisture meters or if they’re just another gadget. Also, on the twice-a-year checks:
That makes sense for harsh climates, but do you think it’s necessary for milder areas? I’m in the PNW, so mostly rain but not much snow.“twice a year isn’t overkill—spring and fall.”
I’ve definitely tracked down a leak just by following that musty smell, especially after a stretch of heavy rain. It’s not always super obvious where it’s coming from, but the smell usually means moisture is hanging around somewhere it shouldn’t be. I ended up pulling back some insulation in my attic and found a tiny drip that hadn’t made a stain on the ceiling yet—so yeah, the nose knows sometimes.
As for those moisture meters, I bought a cheap one out of curiosity. Honestly, it’s been hit or miss. It’ll tell you if something’s damp, but if you already suspect a problem, you can usually feel it or see it anyway. Maybe the pricier ones are better, but for me, it’s more of a “nice to have” than a must-have.
On the twice-a-year checks… I’m in the PNW too, and I don’t think it’s overkill given how much rain we get. I do a quick look in spring and fall—just checking for loose shingles, moss, clogged gutters. Not a full inspection every time, but enough to catch stuff before it gets worse. The rain here is sneaky.
I get the twice-a-year checks, but honestly, I’m not convinced it’s always necessary—especially if your roof isn’t super old.
That’s about all I manage too, but sometimes I think people overdo the inspections out of fear. My place is only five years old and I barely see any issues unless something crazy happens weather-wise. Maybe once a year is enough if your roof is newer and you keep up with basic maintenance? Just my two cents.“I do a quick look in spring and fall—just checking for loose shingles, moss, clogged gutters.”
I get where you’re coming from. My uncle’s shop had a new metal roof put on about six years ago, and honestly, he only does a walk-around after big storms or if he notices something weird, like a leak or a gutter overflowing.
That’s pretty much what he does, and it’s worked out so far. I guess if you’re not seeing any issues and the roof’s still young, twice a year might be overkill... unless you’ve got a ton of trees or crazy weather.“Maybe once a year is enough if your roof is newer and you keep up with basic maintenance?”
