Twice a year is pretty standard, but I’d say it really depends on your roof’s age, material, and what kind of weather you get. Low-slope roofs can be less prone to debris, but they’re more likely to have drainage issues if something does go wrong. I’ve seen leaks go unnoticed for months just because folks skipped a post-storm check. If you’re on a budget, at least walk the perimeter after big storms—look for popped fasteners or pooling water. Photos help, but even a quick phone video can document changes over time. Insurance usually wants to see you’ve done some due diligence, even if it’s not perfect.
That lines up with my experience, especially the bit about insurance wanting proof. I’ve got a flat membrane roof on my shop—honestly, I thought it’d be lower maintenance, but pooling water is a constant headache. I do a quick walk after every heavy rain, not just twice a year. Sometimes I wonder if I’m being too cautious, but after a leak last winter that went unnoticed for weeks, I’d rather err on the side of over-checking. Anyone else find that older roofs need more frequent checks, or am I just paranoid?

Honestly, you’re not being paranoid at all. Flat roofs are notorious for pooling, and once you’ve had one sneaky leak, it’s hard to trust the thing again. I tell folks all the time—older roofs are like old cars: they need more TLC. You’re saving yourself a ton of hassle (and probably money) by catching stuff early. If anything, your insurance company should be sending you thank-you cards...
I get where you’re coming from—once you’ve had water sneak in, it’s hard not to be a little jumpy. I’m actually surprised more people don’t check after every big rain, especially with flat roofs. Have you noticed if certain spots always pool up, or does it change? Sometimes I wonder if it’s worth marking the worst spots with chalk or something, just to keep an eye on them. I’d rather spend five minutes walking around than deal with soggy ceiling tiles again...
Marking the trouble spots with chalk is actually a pretty solid move—I've seen folks do that, and it makes tracking changes way easier over time. Flat roofs are notorious for pooling, and honestly, those spots usually don’t shift much unless there’s been some structural movement or patchwork. I always tell people to check after any heavy rain, especially if you’ve had leaks before. One client kept ignoring a small puddle by the HVAC unit... turned into a full ceiling collapse six months later. Five minutes up there beats a week of repairs every time.
