I bent and soldered up what I call a “triangular” cricket (ridge is not horizontal, but has a pitch which is the negative of the roof pitch - the ridge and the roof when viewed from the side make a symmetric “V.” The visible part of the cricket is comprised of 2 isosceles triangles).
On the roof side, the flashing flange is 8in but on the chimney side, it is only 2in. I was going to make it 4in, but somehow I changed my mind - possibly because at least 2in of step flashing should be covered by counter flashing.
The flashing is 4in tall and the joint with the 2in cricket flange is just all wrong in my book.
The consideration is that there is a dormer within 3ft of this chimney which means the total roof area that will generate water into the cricket is a 3ft by 3ft square area, which is basically nothing.
If the cricket counter lashing completely covers the 2in flange, technically it should be OK, but I still don’t like it.
Soldering more flange material is not going to happen. I was thinking these flashing tapes might be some insurance if I run 4in tape over the 2in flange and still completely cover the 2in with the counter flashing.
