Roofing question- can I patch this underlay

[Bebop Beru]

Got an issue in the loft


Long term I know I need to get it sorted properly but having just just an extension, I’m somewhat tight on funds for big projects, so I’d like to delay for a year.

Is it feasible to patch this? There’s no water ingress.

Thanks for the responses. Will patch it up and keep and eye on it.
