There's a hole in my roof, dear Liza dear Liza

[furtive]

Came home from work yesterday to discover a plate-sized brown stain on the upstairs ceiling so had a look in the loft.

There is a round hole a bit bigger than a 50p in the roof, and it's in the exact place where 3 pieces of the roofing felt join, and the three pieces have sort of curled back exposing the hole.

What's the best way to fix this? Do I need to get the hole in the tiles closed, or can I just repair the roofing felt from inside the loft by getting an extra bit and stapling it all together?

Thanks. I've got a roofer living a few doors down so will go an knock on his door on my way home tonight
