So not only do I need a roof fix in that valley, I also need 6 "max vents" on that side to ensure proper ventilation in the attic. They are taller and have multiple levels of ventilation and seem better than the basic/short caps I have up there right now. $130 each at Rona.
Anyway I was impressed someone could confidently say that was the cause of the water running down the side of the house - no one has been able to figure that out yet.
The downside is they are somewhat swamped with similar calls and the wait is 1-2 weeks.
Here's hoping it actually solves the issue!

Glad to hear things are getting solved. A lot of my ice damming and attic issues were solved by increasing the ventilation a ton. 1950s construction plus a suspicious 90's addition meant that things weren't done that well. For example they didn't join the attic of the addition to the main attic and there was zero installed ventilation on the addition. Yeah. My attic is very cold now, which I understand is the goal.
I also increased my attic insulation and put proper surrounds on all the pot lights and after years of fighting the ice I seem to have a decent solution.
