Help. A friend sent me a couple of videos. I don't appear to be able to attach them so I've attached screenshots. One shows water dripping through the internal wooden window surround. The other seems to show water running down the external wall under the roof ridge, onto the upvc window trim. I don't know how the water is reaching the external wall but I suspect it's getting inside through the upvc trim. My friend had a quick look above the upvc trim and couldn't see any obvious breaks in the sealant. Thoughts and advice for a quick fix and something more permanent please.

How easy can the wooden interior trim be taken off? If not too much hassle to do, this should give further indication re where water is tracking from.
If you/your friend suspect it's getting in where the red arrows are, they could try properly sealing that gap between trim and wall with suitable sealant e.g. Dow 791 or CT1. tbh I'd try that before mucking about with the interior wood, however that might be a good second plan if resealing doesn't work.
Your friend couldn't see any obvious gaps, doesn't mean there aren't some lurking

I think the interior surround is pretty securely nailed/glued, and would be tricky to remove without causing a bit of a mess. I'll pop over and stick a decent bead of the sealant you recommended above the trim.
I'm still a bit confused/concerned about how water is running down the wall though.

A pic from a bit further back would help folk to advise.
Not meaning to tell you how to suck eggs, however when doing the bead of silicon, remove as much existing as possible, thoroughly clean the area and ensure the new bead goes into not just on any gaps.

Check above the roof, check gutters are clear, remove tiles and inspect the condition of the roofing felt, make sure its not rotted and fell behind the fascia
But how is water running down that wall to then go behind the trim?
There was never any sealant there to start with because it appears well shielded, the water running down the wall is the concern

It's possible/likely that's not sealant you're seeing, looks like that's whatever they've used to adhere the trim.
Regardless of what the roofer does/doesn't do, it will do no harm to seal that gap, belt and braces.

Post here either way, I'd be interested to know if filling that gap helped.
No water coming in during the last two very heavy downpours
