Fezza

I think there were weep vents put in there but even if it was leaking from there, there shouldn't be any rain getting into the cavity above the window. Also, it is happening in multiple places away from the windows. I've been up there and had a good look at the roof line - there is nothing obvious. The felt looks like it is lapped over to prevent any water getting in under the tiles. The soffit is fixed to the timber frame - it's timber frame with a block skin. The blocks are then built up to the underside of the soffit. There is compriband tape sealing the gap between the cladding/blockwork and the soffit.

Thanks, Peter. I think there was some rain getting in at the bottom of the cheeks on the window reveal but I think I've stopped that. It's still happening elsewhere, away from the windows so it's a bit baffling.

Thanks, Dave. It's pretty wet at the minute but when it dries out, I'll have a go.

Hi Tony, Here is a drawing of the profile.

Hi Declan, Just taken these shots, hope they help....

Really hoping someone can offer me some advice regarding a problem I am having with some cedar cladding on a new build house. It's a two storey house with the cladding mostly wrapped around the first floor of the exterior with rendered blockwork on the ground floor. When it rains, water is getting behind the cladding. It is running as opposed to condensation or general moisture. Looking up at the underside of the cladding, I can see that the batons are often soaked through, after a downpour. I've attached a couple of images. I really don't know where it is getting in and therefore how I can stop this. The cladding is tongue and groove and is secret fixed to 38mm batons through the tongue of the boards. The fixings used were stainless steel brads and a paslode nail gun was used. I've had several thoughts about how this might be happening and have tried to resolve these potential causes. Initially, I thought it might be running in between the top of the cladding and the soffit. But I've sealed this gap with compriband tape and also a sealant. Then I thought that it could be soaking through the boards. I treated it with Osmo undercoat and the UV oil which has made it very waterproof. My only final thoughts are that perhaps it could be running through the pin hole made from the brads - the boards have moved quite a lot so they might have opened up larger holes? Or the water is being blown up and over the tongue as water sits in the grooves and the problem is far worse when it's windy. Would be amazing if anyone has any ideas or knows what might be happening and any ideas of how to stop it. Thanks.
