Regular checks might feel like overkill, but it’s way cheaper than dealing with soaked insulation or mold cleanup down the line.
Couldn’t agree more. I used to just eyeball things from the ground, but after a small leak turned into a ceiling stain, I’m up there every spring and fall now. Flat roofs especially—one clogged drain and you’re in for a mess. It’s not glamorous, but it beats tearing out drywall later.

That’s the truth. I’ve seen more than a few businesses with flat roofs get caught off guard by a single blocked scupper. It’s not always obvious from ground level, either—sometimes you think things look fine until you’re up close and spot a cracked seam or pooling water. Checking twice a year like you’re doing is a solid habit. I usually tell folks to snap a few photos while they’re up there, too. It helps track changes over time and makes it easier to spot new trouble spots before they get out of hand.
I get why folks say twice a year is enough, but honestly, after what happened to me last spring, I’m not so sure. We had a minor backup that turned into a slow leak—didn’t notice until there was a stain on the ceiling. Flat roofs just don’t give you much warning. I’d argue for quarterly checks, especially if you’ve got trees nearby or your area gets heavy rain. Photos are good, but sometimes you need to poke around with a stick or hose to spot the sneaky stuff.
Quarterly checks might sound like overkill to some, but I’ve seen enough “minor” issues turn into major headaches to know it’s not a bad idea. Flat roofs especially... debris builds up fast and water finds the tiniest flaw. I’ve had tenants call about leaks that started with just a handful of leaves clogging a drain. Twice a year is the minimum I’d risk, but if you’ve got trees or heavy storms, more frequent inspections really do save money in the long run. Photos help, but you’re right—sometimes you need to get your hands dirty to spot trouble early.
Quarterly checks sound thorough, but honestly, I’m not convinced they’re always necessary unless you’ve got a really problematic roof or a ton of overhanging trees. Most commercial flat roofs I see—assuming they’re built right and drains are clear—don’t need someone poking around every three months. In my experience, too-frequent inspections can sometimes lead to more foot traffic than the membrane needs, especially if folks aren’t careful where they step. That can actually cause its own set of issues.
Twice a year is usually enough for most properties, unless you’re in an area with crazy storms or a lot of pollen and debris. After a big weather event, sure, get up there and check things out. But otherwise, I’d focus on making sure whoever’s doing the inspection knows what to look for—tiny punctures, loose flashing, clogged scuppers. I’ve seen more damage from rushed or careless checks than from waiting an extra month or two. Just my two cents... sometimes less is more if you’re methodical about it.
