Old felt DCP above window question

[Poe]

I was just measuring a window for placing the order and I noticed that the cavity has a bitumen felt drip tray as many old houses do.

It is clearing falling apart and needs something better in its placed.

It looks as though a large gap has been left above the window and the felt comes under the angle iron lintel on the outer leaf and is left sat onto of the full width of the window.

Effectively the entire length of cross the to of the window is a continuous weep vent.

My question is is there something better I can do here so that I can fully seal the window without making it into a bigger job than it needs to be.

Or is it a case of sticking some new DPC in there to replace the old and leave it the same?

Hard to get a photo but I tried.

Cheers.

No work required except cut the flaky/overhang off and seal any gap with mastic if you like.

The cavity tray will still perform

Thanks woody,
As I'm replacing the window I'll put some extra DPC under the old as it looks like it is breaking down, just to be safe.
So then once the new windows in just fully seal it and the felt will direct any water to the front leaf and find it's own way out then.
Cheers.

That extra DPC won't be doing anything at all.

Most likely but it's one of those peace of mind things.
I wouldn't bet on the old tray, bricked up a side window a few years back and the felt tray had rotten and had rips and holes all over.
