Holes in roof felt

[jlc]

Hi

Recently moved into a 1930's semi and there are four or five holes in the membrane that runs beneath the roof tiles. The tiles seem to be in reasonable condition so I'm wondering if it is possible to repair the felt without having to take the tiles off? (There is no hint of any water getting in as the loft is bone dry)

Is it possible to do a repair like this? And what is the correct membrane to use under a tiled roof?

Cheers
John

jlc ,
The proper way is to strip back the tiles and battens from outside and replace damaged sections working between rafters.
From inside cut across the lowest part of the damage from rafter to rafter, cut a piece of slaters felt 50-100mm wider than the rafter-rafter size and taper this both sides, slide the tapered edge into the cut and pin the sides to the rafters using lengths of batten. Screw the batten in place - nailing may dislodge tiles.
