Just realized I've been overthinking attic pulls this whole time

Last week I overheard a guy at the supply house say he runs his lines through the soffit vents instead of drilling through top plates. Honestly it sounded sketchy at first but I tried it on a 2 story house in Austin and it saved me over an hour. No more crawling through blown insulation in 100 degree heat. He said he learned it from an old timer who did cable for 30 years. Has anyone else used soffit vents as a path for drops?

Hang on, I gotta ask about this. When you run the line through the soffit vent, are you just feeding it down through the vent opening itself, or are you drilling a small hole through the soffit panel? Because those vents have slats in them and I see some homes where the spacing is really tight. I'm trying to picture how you keep the line from snagging on the metal or plastic edges, especially if you ever have to pull a new cable through the same path later. And what about attic rodents? I've seen mice chew through lines that were just sitting in vents, so I wonder if there's something you do to protect the cable once it's in there. I guess I'm worried about long term durability, even if it saves time today.

Nah, I gotta push back on this one. Soffit vents are for airflow, not cable paths. Drilling through top plates is the standard for a reason, and shoving lines through vent slats is asking for trouble. Those edges can cut through jacket over time, and if you ever need to add another line you're playing a game of snag-city. Rodents absolutely love nesting in soffit gaps, and once they chew through that cable you're going back out in the heat to fix it anyway. You saved an hour today but traded it for a call back next summer. Keep it in the attic, bite the bullet, and drill the holes.

Drill a small hole through the soffit panel itself, don't try to fish it through the vent slats. That way you get a clean entry point and the cable sits snug without rubbing against sharp edges. A little silicone caulk around the hole keeps the bugs and mice out too, saves you the headache later.
