Repairing holes in tar loft felt

[Iwilldoit]

I have the tar like felt under the tiles and in places it has holes - mainly roofers toes have pocked through when they re set the ridge tiles so its small toe/foot sized flaps. I have tried patching with flashband which works well for a while but this time of year some has peeled off.
So any ideas of some fancy polymer, would CT1 work as a glue for some patches made out of shed felt. Or what else could I use as I do not have any shed felt. Something I can buy in small amounts. I do have some spare double width brick DPC roll pieces.
Thank you everyone.

I'm not sure anyone has really found a long term fix other than re-felting it from above. https://www.diynot.com/diy/search/3678869/?q=hole+in+felt&o=relevance

I've done repairs to such, with Flashband. Just gentle with the heat from an electric heat gun to melt the tar on the back of the tape.

Thanks. They seem to be older ones but now we have fancy CT1 I might give that a try.

Thanks. At the time I didn't have a heat gun so softened it over the gas ring then ran up into the loft with it before it hardened up -- think - its a knock out and you you will understand
I now do have a heat gun to use. Some of the flashband has stayed on but other bits have fallen off. Problem is that you can not press it too hard for fear of making it worse.
