Hi everyone
I have water coming down the back of my chimney and into the hearth. We have a wood burner attached to the flexi liner that goes up onto the roof via a twin wall stack. Over the last 12 months we have had three different roofers/chimney companies take a look and all say they can find no fault with the roof. The steel stack appears to be well sealed. In the loft everything is dry including the twin wall pipe that we can see. The wood burner and flue liner are roughly 16 years old. Anyone have any ideas or tips please? Many thanks.
