I’m just wondering if anyone’s actually seen a big difference after upgrading insulation or venting, versus just adding more underlayment.
I get where you’re coming from—nobody wants to shell out for a full tear-off if it’s not needed. I did add more insulation in my attic (also borderline, according to the guy who checked it), and it actually made a noticeable difference. Not perfect, but fewer icicles and no leaks last winter. I skipped the full ice shield because of cost, and honestly, with your shallow pitch, I’d focus on sealing up air leaks and boosting insulation first. It’s not just throwing money away—your heating bill might drop too.
I’ve seen a lot of folks get better results from tightening up insulation and sealing attic bypasses than just piling on more underlayment. One house I inspected last February had almost no ice damming after the owner focused on air leaks—didn’t even touch the roof. Still, venting matters too, especially with older homes that weren’t built with airflow in mind. Sometimes it’s a combo of small fixes that really add up.

That’s been my experience too. I’ve managed a few older duplexes where just sealing up attic hatches and around light fixtures made a bigger difference than adding more insulation. One thing I’d add—don’t forget about bathroom fans venting into the attic. I’ve seen that cause surprise ice dams even when everything else looked good. Quick checklist: seal leaks, check insulation depth, make sure vents actually go outside... it’s not always glamorous work, but it pays off.

I’ve definitely seen the same thing—sometimes just tracking down those weird little air leaks around pipes or chimneys makes a bigger dent than dumping in more insulation. One thing I’m curious about: has anyone tried using those attic stair covers? I keep reading mixed reviews. Wondering if they’re worth the hassle or if just weatherstripping is enough.
Attic stair covers… yeah, I’ve wrestled with those a couple times. Honestly, the first one I installed was a comedy of errors—me, a staple gun, and a lot of cursing. But once it was in, I did notice less draftiness around the stairs. Weatherstripping helps, but if your attic door is right under a cold spot (like mine), that extra layer really cuts down on the ice dam drama. Not magic, but worth it if you’re already up there poking around.
