I hear you on the cost of ignoring those drains. I thought I was being smart, saving money by only doing a yearly check—until a squirrel’s nest blocked my downspout and I ended up with water stains in two rooms. That repair bill stung way more than just hiring someone to do a quick check after big storms would’ve. I’m still not convinced you need to walk the whole roof every time, but skipping those key spots is asking for trouble. For me, it’s about balance—protecting the roof without overdoing it or blowing the budget.
That’s a fair point about not needing to walk the whole roof every time. I’d just add, from what I’ve seen, even missing one clogged drain can cause a lot of damage—especially with flat roofs or green roofs where debris builds up fast. I usually recommend at least a visual check after heavy storms, focusing on drains, seams, and any spots where water tends to pool. It’s not about overdoing it, but those quick inspections can save a lot of hassle (and money) down the line.
I get where you’re coming from about checking after storms, but do you ever worry that too many quick inspections might actually cause more harm than good? I’ve seen folks accidentally damage membrane seams or crush insulation just by walking around too much, especially on older roofs. Sometimes less is more—if you know your trouble spots, maybe it’s better to just monitor those closely and leave the rest alone unless there’s a real reason. Anyone else run into that?
I get what you’re saying about overdoing it, but honestly, I learned the hard way that skipping regular checks can be just as risky. My place has a flat roof—old torch-down membrane—and after a mild storm last year, I figured it was fine since there were no obvious leaks. Fast forward a few months, and I found water stains in the ceiling. Turns out, a small puncture had gone unnoticed and got worse over time. I’m careful not to stomp around up there, but for me, a quick walk-through after big storms is worth it, even if it means being extra gentle. Sometimes those “trouble spots” aren’t where you expect.
That’s exactly why I don’t trust a “no visible leaks, must be fine” approach.
Couldn’t agree more—my old EPDM roof looked perfect from the hatch, but water was pooling near a drain on the far side. Didn’t spot it until I crawled over there and saw the membrane starting to bubble. Out of curiosity, do you use any kind of moisture meter or just visual checks? I’ve debated investing in one, but not sure if it’s overkill for a small building.“Sometimes those ‘trouble spots’ aren’t where you expect.”
