Roof ridged but leaks and mold repost!

**Sorry repost it got deleted because i used a naughty word 

We've just had our house roof ridged around the corners and top instead of cement titled on the bricks as the cement was starting to fall off and small mold patches in the upstairs bedrooms, However, since this, the mold has increased, and got a lot of lot worse with even water to be seen. The question is I'm going to phone them tomorrow but if they are moody about it who would I complain to?’

Nothing was done in the loft but it has been insulated on the floor back when it was offered a few years back. 

p.s-Where the sky dish is located in the first picture is also where you can see the water in the 3rd picture

How come no one's replying now but i had ten posts before,i wasn't rude to anyone just said a naughty word regarding the work done that i didn't know you couldn't.

Just want advise on what people think it could be or if they claim its not we have kids in the house

I've been out all day.  Bit disappointing to lose some considered posts in the fallout! 

I'm eating now, will fill in some gaps later or early in the morning but I think you have condensation, not a leak. 

I was asking about the insulation situation up there.

Sometimes it just takes time for people to see the new post, and they may feel that they posted everything they could think of in reply to your first post. I've only just seen it. 

So the roof has had a new ridges tiles on the top ridge and the ridges of the hips. Externally it looks like a good job, but it could still be leaking. However the design on the roof means that you have very little space for insulation at the eaves. You might also have some undercloaking at the eaves that is failing. It doesn't look like the roof has been completely re-roofed with new tiles. Has there being any work done to improve the waterproofing or insulation at the eaves? e.g. have new eaves support trays been installed under the undercloaking? 

If not, I think the cause could be the work that hasn't been done, rather than the work that has been done. However, the fourth photo seems to show a clear pattern of mould towards the hip rafter. This could indicate that water is running down the hip rafter, or it could just be that it is colder at the hip because it is exposed on two sides.  

So you need call them and ask for help to review whether there is a problem with their work. I don't think we can say that there is, and you might need their help, or another specialist to help confirm the cause. 

There is a channel on YouTube called Gosforth Handyman where the channel owner owns a house with the same design of roof as you have. I know that he did some work on improving the insulation in the roof, and you might find some useful information about how to improve your roof on the channel.

Thank you very much for the replies,as for the  eaves i have no idea what they are but google seems to suggest the corners.i'm not aware but ill ask tomorrow.

I think you can see it from the pictures but i believe most the problem comes from the guttering dipping in the middle if you look closely, Where they had the  scaffolding up

I'm with Doozer on this one. That looks a lot like mould from condensation.

I agree it looks like condensation.  It is very unlikely that there is any insulation at where the ceiling is sloping  as the loft does not extend beyond the top of the slope. Thus the ceiling is cold there and attracting condensation.  The dripping water in the 3rd photo is very likely consensation which is running down the slope and collecting and dripping from that little triangular horizontal area at the bottom. 

PS. I suggest that you dry the ceiling with a cloth and put the heat on in the room where there is dripping water and put a dehumdifier in the room for a few days.  Then watch what happens when it rains.

Thank you, I'll phone them tomorrow and ask them for advice and will look into the best way to deal with the condensation.
taking this all in it seems i need to get the top side of the loft done as i have with the floor?

You only need to put insulation in at the strip of ceiling that is sloping which appears to be about 12 to 18 inches wide.  You might need to take the plasterboard off to get the insulation in there.  You will also need to put a vapour barrier on the warm side of the insulation, ie. below it.  No need to put top or roof insulation in the loft if you already have insulation in the loft floor as far as I can see.
