Hi, had a leak after the heavy persistent storms last Wednesday which I assumed was from the roof. Had that all sorted but it doesnt seem to be drying and the damp patch seems to be expanding.

Its in the kitchen with the bathroom above but that all seems dry, hardly ever use the shower as I have one at gym so dont think its that.

Would it normally take this long to dry or think I have another issue somewhere?

Thanks so much in advance
