Damp

[david123]

Quick update
I have removed all the plasterboard that was damp. You can see by the photographs where. The bricks are, and that is where the plasterboard was at its wettest. All the plasterboard that is left in situ is about 0.2 %, so i am happy with that. We are expecting rain here for the next 3 days is we will keep checking while I have it exposed. At least I am now in a position to see what is happening. Ladder and hose I will do if it doesn't rain sufficiently to give it a good test.
Photographs did inot come out very well but I have cleaned out the one that shows the brick wall, it is about 4 inches deep.

Hard to tell from the pics. You stand a better chance of seeing the problem now the ceiling is open. Keep us informed.

As the rest of the plasterboard is bone dry around the hole i should be able to see/feel where it is coming in and deal with it. I will come back with the outcome when I have found it.

Thanks for all your advice.

Just nipping into the garden to do a rain dance .... Do I need fearhers in my hair to make it work? Or will dancing around looking a Pratt do the trick?

Difficult to tell - perhaps you could post a video of your attempts so that we can all judge :lol:

You say the brick wall is about 4" deep? This would indicate a cavity wall so I'd be looking at the main roof for a leak. A good indication from underneath is generally missing bit of felt. From outside it could be a broken or missing slate/tile.

in your picture there is no insulation was it insulated if so was that wet? is the felt wet? could be condensation on the roof felt under side, have you sorted it yet

As I said earlier, it would be a good idea to check the verge, the water leak is coming from above the plasterboard stain.
It will probably be a lead flashing/apron or a porous or broken tile that is the problem.
That tile looks like a Marley Modern, several years old and prone to being porous, granulated tiles are worse.
A dry weather Easy fix is Thompsons water seal paint liberally down the verge area and cemented verge.
should last a couple of years, two coats would be better. Do NOT do this off a ladder!
Or You're roofers will have to remove the tiles and any clips, replace or repair the ladder truss/rafters, replace the verge strips and any rotted felt and batten and Retile. Regards Rodders

Found the problem. We had a downpour last night and checking the hole in the ceiling found that there is very small hole a in the roofing felt with water dripping through. Rang the roofers this morning and they are coming back to have another look.
Leaving the hole open until they have found where it is coming in.

 

[Graham Orm]

Good stuff David, at least you've found it. The hole in the felt is only part of the problem, they need to find where it's getting through from outside.

As it intensifies with the weather it's a leak from water tracking through the verge cement, a broken tile , the ridge or a combination of the them.
If they are opening up the verge to repair the whole pine end felt and not a patch job, why not get them to price for fitting individual "dry verge", rather than re-cementing?

 

[david123]

I will make sure that we get to the root of the problem when they turn up, whatever it takes. Thanked for your comments.

Roofers been back and did find the leak that was dripping through a hole in the roofing felt, they found a cracked tile and replaced it, and fixed the hole. Had lots of rain since and it seems to be now cured. This morning I have patched and plastered the hole and waiting to finish it of. Phew

Thank you for all your help

 

[Graham Orm]

Great stuff Dave. Glad you found it ;-)

 

[david123]

Thanks mate,
I also spayed the brickwork that I could see ,with Thompson's water seal (belt and braces).

I also spayed the brickwork

I didn't think brickwork had genitalia :shock: :shock: :lol:

We'll if it's going to wet itself!!!! It has to pay the consequences.
