Leak in our roof

Black_Knight

Noticed with the bad weather (wind and rain) we got some water marks on the ceiling of one of our rooms. After checking the attic out I found many instances of nails just coming straight through the felt, and not into a rafter. The nails are rusty (sign of water), and after putting a lunchbox under one of the suspect ones (and hopping in just now during a downpour) I can see it is indeed leaking. There's also another mystery leak source higher up from it (it was gathering on the insulation and kinda spreading - trying to track that one down, but I suspect it's the same thing as i've seen multiple instances of these missed nails (though not all leaking).

2 nails at the top of this pic.


You can see the joist is damp here from where the insulation was touching it and letting water spread.



Any thoughts on what my options are? I suspect there's ingress between the tiles and felt somewhere higher up, and it's getting into the attic via these nails in these 2 or so locations. Hard to see anything from the outside (i've a skylight near that area) but there's actually a decent amount of moss on the tiles (east facing)

whats directly over that area. is that a stud wall of a room in the second pic.

the great thing about tiles is that you can take them off nd have a look and then put them back.
probebly a broken tile, damaged ridge or the window.

Not sure what you mean by "directly over that area". Roof is what's over it. Both pics are in the eves of an attic conversion, the second pic is the wall of the stuff conversion.

I'll try get a look at the tiles in the morning. Too miserable outside today to stick my head out. The window is a rafter away from the leak, so not that, but the moss on and around the ridge isnt insignificant. Could be a factor.

i mean whats farther up the roof from that area.
i wouldnt rule out the window. water can travel a long way before it comes out.
i know one roof that had a leak and it had to be stripped to solve it. the leak going in was 12 feet from where it was comeing out inside. it came in on a bad ridge tile on a hip and ran across a lat until it driped off

are they screwed on ridges or cemented on.

Here's from the inside of the attic conversion. The damn cross beam would be about a foot to the right of the window, and about a foot lower. The 2 nails would be that same foot to the right, but about a meter down the roof from the bottom of the window pictured.



Here's a pic directly up from the velux. The leak would be towards the left side of this pic, and lower down



They look cemented from my limited knowledge.

Is that a nylon rope visible on top right of last photo? Has someone been on roof repairing chimney/ fixing TV aerial and may have damaged tile ?
As a temporary measure - gently cut dripping nails flush with felt and pull felt slightly back off and slide a strip of felt or stiff polythene down to divert the water down - the actual water ingress could be way above these nails.

Not a rope. It's a sky dish cable. Hate that that's how it's installed, but twas there before we got here.

I suspect the water ingress is far above the nails, given the leak further directly up from the nails.
