I have got Tec7 Roof so I could run a bead of that along the edge of the lead top cover.

The first two pictures are of the back of the chimney where it is leaking . The third picture is on the side which looks better. The other picture shows how tall the stack is.

I've taken photos and there are no soakers under the tiles , just a strip of lead over the top.

I'll try to get up there and take some pictures of the flashing if the weather is better this week.

I was wondering about Storm dry because I think the issue is saturated brickwork and it would be better to stop the water getting into the stack in the first place rather than stopping it getting further down with a lead tray. Has anyone else any input on the effectiveness of this treatment? The chimney pointing is in good condition.

This morning after another night of heavy rain and wind the water was running down the stack bricks inside the roofspace. I'm drying it out with a fan heater . How far can rain drive under lead flashing? The tiles are flat and the flashing only extends 3-4 inches over the tiles. I had the flauncing re-done on the top of the chimney because it was cracked. There is a chimney cowl on the top of the pot.

Yes , the flashing round the chimney looks in good condition. I've sprayed the brickwork on the stack with Screwfix brick sealant. Another query I have is about the wisdom of fitting a flue liner and surrounding it with vermiculite. Surely that could create dampness. I always understood there should be ventilation in a chimney.

There are damp patches appearing on the wall above the stove and at the coving where the ceiling joins the wall. In the roof space the woodwork around the base of the chimney is damp and the brickwork is damp.

I have a problem with water ingress in my chimney. I have a woodturning stove and a stainless steel liner in the flue. The house is a bungalow built in 1953 but the chimney has been re-built at some point. The stack is on the edge of the house and does not come through the roof so it is very high -about 8 feet and only 2 bricks wide x 7 bricks long. There is no lead tray. A builder has told me i need the stack taken down and rebuilt with a lead tray . I would like to know if fitting a tray will make the stack weaker and wonder if that was why there isn't one. Is there any other way I can waterproof the stack without re-building it?
