I’m right there with you on the drains—those things are sneaky. I had a flat roof on a retail space where one drain got clogged with leaves, and by the time we caught it, water had already seeped into the drywall below. Ended up replacing insulation and ceiling tiles in two units. Not cheap.
I’ve tried drone inspections too. They’re decent for spotting obvious stuff like missing shingles or ponding, but they just don’t catch the little things—like a loose fastener or a tiny split in the flashing. I still think you need someone physically up there, especially after a big storm or if you’ve got a lot of trees nearby.
I get why people want to save money by stretching out inspections, but honestly, every time I’ve seen that happen, it’s bitten someone later. Insurance adjusters aren’t shy about denying claims if they see signs of neglect either. For me, once a year is minimum, and I’ll do a quick walk myself after any major weather just to be safe. Maybe overkill, but I’d rather deal with an invoice than mold remediation...
I get where you’re coming from, but I actually think once a year might be a bit much for some roofs, especially if you’re in a milder climate or don’t have a ton of trees around. When I bought my place last year, the inspector suggested every 2-3 years unless there’s visible damage or after a big storm. I do keep an eye out for obvious stuff—like pooling water or missing shingles—but I haven’t found much that needed urgent attention. Maybe it’s different for flat commercial roofs vs. pitched residential ones, but I’m trying not to overdo it and stress myself out.
Flat commercial roofs are a whole different animal compared to pitched residential ones. In my experience, even if you don’t have trees dumping leaves everywhere, those flat roofs love to collect debris—like they’re running a lost-and-found for the neighborhood. I get not wanting to stress, but a quick walk-around after a storm or heavy rain can save a lot of headache (and cash) down the line. I’ve seen tiny punctures turn into indoor waterfalls... not fun. Every 2-3 years is probably fine if things look good, but I’d still peek up there now and then, just in case.
That makes sense about the debris—mine’s not under any trees either, but I still find random stuff up there after a windy day. I’m curious, though: do you usually just check it yourself, or do you bring in a pro every couple years? I’m a little nervous about missing something important since I’ve never dealt with a flat roof before. Also, does anyone actually keep a log of inspections or repairs, or is that overkill?
I usually do a quick walk-around myself after storms or if I hear something hit the roof, but I still get a pro up there every couple years. Flat roofs can be sneaky—stuff like tiny cracks or pooling water isn’t always obvious unless you know what to look for. As for keeping a log, I just jot down dates and what I noticed in my phone notes. Not overkill at all... it’s saved my butt when warranty questions came up.
