Hi I have a hole in the material between my roof tiles and the wood joist due to a dislodged tile and I think a bird that has pecked a hole in it.

What is the best way to fix the material ?

Thanks

Not sure from your description what you re describing here .......Is this on the roof edge (gable) ie.between the tile edge and the fascia ? or is ot the lower edge of the tiling - ie. immediately above the guttering ? OR are you seeing o hole in the roof felt from inside your loft ?

I am seeing the hole from inside the loft and outside I can see a tile has moved are broken, not on the edge but on the roof centre.

First thing you should be concerned about is getting the rooftile sorted - from you description it sounds like you may need to get a roofer as I would never suggest a novice starts climbing on roofs. A roofer will be able to recommend whether / how to repair the secondary layer ( the bit you think the birds have pecked at) which is likey to be felt (if its an older roof) or if its a newer roof this layer may be a thinner breathable membrane. Repairing felt or breathable membrane is not such and easy job - as I undersatand it much of the roof tiles would have to come off to have a large section totally replaced. That said some older houses gat away without a felt layer at all and so long as the tiling is sound a good roofer will be able to advise whether simply getting the tiling properly repired may be an option.

Keep us posted.
