leak in loft

[snadge]

we had high winds yesterday coming from other direction it usually does and the wall on the stairs was soaked, I went into loft and found that a tile had been chipped and a 3inch by 0.5inch hole , It was letting in water but the plastic sheets that go between the tiles and joists were not over-lapped in places and where the water was coming it was overlapped by a few centimeters and water build up caused it to dip and spill - its like this all the way along on two sections

what can I do too seal this up?

I will be sorting out the tile too but want to address the membrane incase wind blows water back up the tiles again.

is there any kind of wide tape I can get to seal the sheets together to stop water from being blown back through? - like I say in some places there are holes where they dont overlap

I would have thought it should have been overlapped by a good 1 foot and sealed?

thanks in advance

Fix the tile not the membrane.

Fix the tile not the membrane.

well I thought it would be obvious I would be doing that anyway ...lol

but, the rain can still get in when blown up the tile by wind, that is why the membrane is there and overlapped as so to run the water down to bottom - regardless of fixing the tile the membrane needs addressing too,

Millions of houses across the UK do not have any membrane at all and they don't leak.

I

If it is plastic you can get tape that`s used on plastic Damp Proof Membrane ( or radon membrane )
