Just got a call from the Mrs and nipped home to find the flat roof over the kitchen extension is letting in water had a look up top no visible tears or splits in the tarpaulin it has that silver gunk pasted all over it there seems to be a lot of bubbling very large in places but no water sitting under , it im guessing as the water is dripping every 5 seconds through the light fitting close to the main house wall that it is coming in where the roof meets the original building as the work looks shoddy against that edge , advice to seal it temporarily ? and where do i stand with buildings insurnace is the type of thing they cover ?
If the leak is at the join between two parts of the house, then it's most likely to be a flashing issue. Does flashing (usually lead) look like it has split, worn or come out of the mortar joint?
The silvery coating that's on the roof already might be a waterproof coating put on there to cure a previous problem!
You can buy self-adhesive flashing but it eventually comes unstuck, stick with using lead if you have to replace it.
Acrypol is a decent roof coating, just done mine and this weather is being an ideal test for it!

Be thankful it isn't like the one we've got, a section of the felt under the tiles has disintegrated as the tile lath has cracked and punched through the felt. The water has pooled on top of the plasterboard ceiling and caused it to disintegrate as well so when I touched it it fell apart, so bucket in the loft and another in the lounge till Monday/Tuesday when we can get someone out.

Cheers mate i think it is the lead flashing as it was missing from the side that the roof is leaking now you mention it
You can get non-lead flashing made of plasticy synthetic stuff that sticks on and paint on b
humen-a-like stuff too.Just repaired the flashing on my flat roof with this and it seems good so far. Lead flashing costs a bloody fortune.
My mate did his roof with the same stuff and that's been good for a few years.

Somebody with big heavy feet is responsible for that.mrmaggit said:

Don't walk on flat roofs. It pushes the grit through the felt.I wish to point out this is a pitched roof with tile lath then felt, the ceiling section that came down was because a puddle had formed on it weakening the plasterboard so the moment I touched it it just disintegrated, you have to love how insulation acts as a sponge holding the water and preventing it evaporating off again.
So Monday or Tuesday hopefully we can get someone round to strip the tiles back fix the felt and lath then put the tiles back. Till then it's bucket in the loft time.
