"Funny thing is, when we went back to inspect a few years later, the spots I fretted about most were perfectly fine."
Yeah, that's usually how it goes. I've seen plenty of roofs where the areas people obsess over turn out just fine, while the sneaky little corners or edges you barely glanced at end up causing headaches later. It's good you're already keeping an eye on things at the three-year mark—regular checks really are key.
One tip I'd add is to make sure you're inspecting after heavy storms or extreme weather shifts. Modified bitumen tends to hold up well, but temperature swings and moisture can still expose weak points over time. And don't underestimate the value of a quick visual check from ground level every now and then; sometimes you spot issues from a distance that you'd miss up close.
Sounds like you're doing everything right though...keep trusting your instincts and experience.
Haha, isn't that always the way? I remember obsessing over this one seam on my modified bitumen roof—checked it constantly, convinced it'd leak any day. Fast forward a few years, and that spot was pristine. Meanwhile, a random corner I barely glanced at decided to spring a leak after a nasty storm. Go figure, right?
"Modified bitumen tends to hold up well, but temperature swings and moisture can still expose weak points over time."
Totally agree with this. Ever notice how it's always the sneaky spots you least expect that cause trouble later on?

Yeah, those sneaky spots always seem to have a mind of their own. But honestly, insulation plays a big role too—poor insulation can cause condensation buildup, weakening areas you'd never suspect. Ever checked if your insulation's consistent across the roof?
Could be insulation, sure, but honestly... modified bitumen roofs can be tricky. Had a similar issue myself—turned out the flashing was installed poorly. Might wanna double-check that before blaming insulation alone.
"modified bitumen roofs can be tricky. Had a similar issue myself—turned out the flashing was installed poorly."
Agreed, flashing is often overlooked... but honestly, from what I've seen, ventilation issues can cause just as much trouble. Had a job last month where moisture buildup was mistaken for insulation failure. Worth considering before you rip anything apart.
