They helped with ice dams a bit, but regular gutter cleaning and making sure my attic insulation was up to snuff made a bigger difference in the long run.
I’d push back a little on the insulation point. In some of the older properties I manage, no amount of added insulation stopped ice dams entirely—especially after heavy snow years. Sometimes, it really comes down to roof design and ventilation. Gutter cleaning helps, but I’ve seen cases where even spotless gutters didn’t prevent issues. Just saying, sometimes it’s not just about maintenance, but also about the original build quality and local weather quirks.

That’s been my experience too, especially with my place (built in the late 60s, low-pitch roof, northern climate). I did the whole checklist—blew in extra insulation, sealed up attic bypasses, even put in a ridge vent. Still got ice dams after a couple of those really heavy snow winters. The insulation helped a bit with heating bills, but didn’t totally solve the damming.
Gutter cleaning is a must, but like you said, it’s not a magic fix. I’ve had years where the gutters were spotless and still ended up with water sneaking in under the shingles. I think a lot of it comes down to how the roof was designed in the first place. Some older homes just weren’t built with modern snow loads or ventilation in mind.
I looked into heat cables for the eaves, but honestly, the cost adds up fast—both for the cables and the electricity. Not really in my budget unless things get worse. For now, I just try to keep the snow raked off the lower part of the roof after big storms. It’s not perfect, but it’s cheaper than a full roof redesign.
One thing I wish I’d known: when I replaced my shingles a few years back, I should’ve asked about better underlayment or ice/water shield. The basic stuff the contractor used didn’t do much when the melt started pooling. If you’re already re-roofing, it might be worth spending a bit more there.
Anyway, I agree—sometimes you can do everything “right” and still get issues, especially with older houses and weird weather swings. Maintenance helps, but it’s not always the whole answer.
I’m right there with you on the underlayment—wish I’d known more before my first winter. My place is early 80s, and even with new shingles, I still got some seepage at the eaves after a thaw. I did a ton of research, but it’s wild how much depends on the original roof pitch and venting. I’ve been tracking attic temps and humidity just to see if I can spot patterns, but honestly, sometimes it feels like you’re fighting physics more than anything else.
That’s the thing—sometimes you do everything “right” and water still finds a way. I’ve seen so many older homes where the roof pitch just isn’t steep enough for heavy snow melt, so even with ice & water shield, there’s still trouble at the eaves. Tracking attic temp is smart though. I always tell folks, ventilation can be a bigger deal than most people realize, especially in those 70s/80s builds... you’re basically trying to outsmart decades-old design choices.
I’ve been stressing about this exact thing since we moved in last year. Our place is from the late 70s, and I’m realizing just how much attic ventilation matters—there’s barely any up there. We had some minor ice damming at the eaves even though the roof was replaced five years ago with all the “right” materials. I guess you can’t really fight physics if the pitch is too shallow. Thinking about adding more soffit vents before next winter... anyone else have luck with that?
