How often do you actually get your business roof checked?

Full inspection still means getting boots on the roof, but tech’s saved me a lot of time (and knees) lately.

I get the appeal, but honestly, I’ve found tech can give a false sense of security. Had a flat roof last month where the drone and thermal looked fine, but once I was up there, found a seam split hidden under some gravel. Sometimes you just can’t beat actually poking around up close, even if it’s a pain.

I hear you on that - tech’s great for getting a quick overview, but there’s stuff you just can’t spot unless you’re right up there. I’ve seen plenty of “clean” drone scans where the membrane looked perfect, but then you find a puncture or a popped fastener tucked behind an HVAC unit. Especially with older roofs or ones with lots of foot traffic, I don’t trust remote tools alone.

Curious how often folks are actually scheduling hands-on inspections? I’ve got clients who only call after a leak shows up, and others who want me up there every six months, rain or shine. Personally, I think twice a year is the sweet spot for most flat commercial roofs, but maybe that’s overkill for some setups. Does anyone here do more frequent checks, or just stick to annual?

Annual checks have actually worked fine for a lot of places I’ve seen, especially if the building’s newer or doesn’t get much rooftop traffic. Twice a year seems like a lot unless you’re in a spot with wild weather swings or heavy equipment up there all the time. One thing I’ve noticed - sometimes people over-inspect and end up walking more damage into the membrane than they find. I’d say, if you’re seeing issues every time you go up, maybe bump up the frequency, but otherwise, once a year with a solid checklist usually catches the big stuff.

- Totally agree, annual checks are usually enough for most spots, especially if the roof isn’t a high-traffic zone.
- I’ve seen folks do more harm than good by poking around too often - membranes don’t love all that foot traffic.
- If you’re in a spot with crazy hail or wind, maybe consider spring and fall checks. Otherwise, one solid inspection with a thorough checklist usually does the trick.
- Quick tip: always check after any big storm, even if it’s not “inspection time.” That’s when surprises pop up.

Title: Annual Checks Worked… Until They Didn’t

I used to be in the “once a year is enough” camp, especially since our building’s got a green roof - not much foot traffic up there, and I figured less disturbance was better. But then last spring, we had a stretch of weird freeze-thaw cycles, and I noticed some pooling that wasn’t there before. Turns out, the drainage layer had gotten partially blocked by debris that blew in during a storm months prior.

Here’s what I do now: I still stick to one big annual inspection (usually late spring), but I’ve added in two quick spot checks - one after leaf drop in the fall, and one right after the worst winter storms. For me, it’s less about walking every inch and more about checking key points: drains, seams, and any spots where equipment sits.

One thing I learned the hard way: more inspections don’t always mean better results. Too much walking on the membrane, especially if it’s wet or cold out, can do more harm than good. But ignoring it for a year just because “it looks fine from below” isn’t great either. That blocked drain cost me a couple grand in repairs - lesson learned.

I do think climate matters a lot here. We’re in the Midwest, so wind and hail aren’t constant threats, but those freeze-thaw cycles are brutal. If you’re somewhere with heavy hail or high winds, bumping up to twice a year - spring and fall - makes sense. Otherwise, just keep an eye out after any big storm like others have said.

One last thing: if you’ve got solar panels or a green roof like mine, make sure whoever’s checking knows what they’re doing. A careless step on a root barrier or solar conduit can turn into an expensive mistake fast.
