Flat roof gap at chimney breast - advice pls?

[Gordsworth]

Hi
My flat roof (14 years old) joins to my chimney breast as per the photos attached.

A slight (half a centimetre) gap has appeared between the end of the felt and the chimney breast.

If I press the upright part of the felt it feels securely bonded right up to a few cm below the gap.

As you can see I've drowned the gap in liquid rubber paint.

Just wondering though if this is a serious sign of roof failure, and what the smartest remedy might be?

Any and all advice much appreciated!

Cheers
G

Yes it's what happens with age, the felt upstand comes away

You could try heating it up and pressing it back, and securing it back into the joint

Otherwise, fit a lead, or lead substitute flashing over the upstand

You could seal it with some polymer mastic. Hippo is good stuff.
