I hear you on the ice dam drama—my attic looked like a science experiment last winter. I ran heat cables mostly on the north and shaded eaves, but honestly, if your whole roof’s a freezer, a wider install might make sense. You’re right about weird melt patterns; I’ve seen some patchy spots, but nothing catastrophic. Still, if the insulation is drafty, the cables are just a Band-Aid... but sometimes, that’s all you need to survive until spring. Drywall repairs are a special kind of pain, for sure.
That attic “science experiment” vibe is too real. I’ve seen some wild icicle formations that looked like something out of a cave tour... Heat cables definitely help in a pinch, but you nailed it—if the insulation’s not up to par or there are air leaks, you’re just treating the symptom, not the cause. Did you ever get a look at your attic ventilation? Sometimes, even with decent insulation, poor airflow traps just enough warmth to start the whole freeze-thaw mess.
I’ve noticed on some houses, the weirdest melt patterns show up where the roof meets valleys or around dormers—almost like the snow’s playing favorites. Not sure if you’ve tried it, but sealing up those little attic bypasses (like around plumbing vents and light fixtures) made a bigger difference for me than I expected. Still, when the snow piles up fast, sometimes you just have to cross your fingers and hope the cables keep up. Drywall repairs... ugh, I’d rather shovel the driveway twice than patch another ceiling stain.

You nailed it—those stains haunt me every spring thaw. One thing that helped here (old house, northern climate, lots of weird roof angles) was adding baffles to keep the insulation from blocking the soffit vents. It’s not glamorous work, but it actually made a difference in those “favorite” melt spots you mentioned. Still get some funky icicles, but at least I’m not chasing water stains across the living room anymore.

I’m with you—icicles are a pain, but I’ll take them over ceiling stains any day. I tried heat cables last winter, but honestly, they didn’t do much except run up the electric bill. Anyone ever just bite the bullet and replace their attic insulation entirely? I keep wondering if that’s worth it or just overkill.
I hear you on the heat cables—mine barely made a dent, just like you said. Full insulation replacement seems drastic, but I’ve read it can help if your attic’s way under code. Did you check for air leaks first? Sometimes it’s just a few gaps around vents or the hatch causing most of the trouble.
