Head of Window Sill leaking

[Umy786]

I’ve got a bad leak with water coming through the top of a window head (reveal?), water is dripping down right from where the silver trim is

It’s on the rear addition of the property.

Gutter are fine, I’ve got cavity / felt support / eaves trays in place and the tiling looks good up there

I had the parapet wall re-plastered about 8 years ago with new code 4 lead work across the parapet and adjoining main building but it’s somehow getting straight through the tiles and underlay, below the felt.

I just can’t understand what it could be and I can’t get anyone out for 2 weeks

Anyone know what the issue could be possibly??

Check drip trays? They OK.
Called
Eaves Protector Support Tray.

They are fine, there is water coming in from further above as I’ve seen some pooling / water gathering near the lowest battens, just above the tray

You've also got loads of drips on the underside of the gutter which means the tray and the felt are not right.

The underlay needs trimming back .
It could be drawing water like a wick onto the u s t .
Then it may track under the tray side laps .
Roof pitch is to flat for those tiles and gutters to low

I am also thinking it too flat, Need about 25 degrees for those!

Thanks for the replies

Really shocked to hear those tiles aren’t suitable, I’ve had the place 15 years and various roofers out, none of them have ever said the pitch is too low for them so quite surprised to hear this

I was ask the roofer whenever he gets over.

I was always under the impression that the underlay must always run into the gutter from the tiles

What type of tiles would be suitable for this pitch of roof ?

No that's not correct , that's why you use under lay support trays.

And yes the pitch is to low , regardless of anything others say. They appear to be Anchor Vangaurd.. .
Measure the pitch to see suitable tiles. Id guess less than 15 degrees

Roof leak. Check in the loft. Water pooling in gutter doesn't look good either. But, these are separate issues.

 

[Umy786]

Unfortunately there’s no access into the roof as it is a rear 2 storey addition to the main house. Agree gutters probably not helping but this is an issue which has reared its head a few times now.

I’m reticent to putting a lot of money into a new roof as I plan to do a loft conversion next year

You don't need a new roof. If you have no access from below then your only option is to lift the tiles and find the water entry location and fix that. The leak would have created a hole in the felt.
