Wait, you PULLED it back 3 feet? That's a LOT of extra heat you were trapping. But honestly, the REAL missed inspection is why nobody caught the actual hot spot right above that insulation line, that's where your roof deck is probably cooking all summer and warping the shingles slowly. That's the part that'll cost you later, not just the temp difference.

honestly I've seen that trick floating around too and I get why people like it but I have to say I'm not sold on it. zip ties can crack or get brittle after a season of sun and salt, especially if you're in a place like Galveston where the heat is brutal. I've had more issues with the little plastic tabs breaking than I've ever had with water getting in through the seal itself. the real fix for me has always been just checking that o ring and greasing it up before every single trip, takes thirty seconds and saves you the headache. plus those zip ties leave a weird bump that can mess with how the housing sits on a tripod or rig, which matters if you're doing any kind of timed shots. so yeah, I'd say use it as a backup but don't rely on it as your main line of defense.
