Twin Wall Flue Storm Collar...

[Mulberry View]

I need a good quality Storm Collar for a 6" Twin Wall Flue, to go above the lead roof flashing. I've had a couple of goes at it, they're all just flimsy crap with poor adjustment that pulls the thing out of shape and it ends up leaking.

 

Any good recommendations?

Have you not got a big rubber flange thingy with an aluminium outer that slides over the flue. 

This is what I have, I have never got around to actually fitting it down to the roof it is just slid on and pushed flat to the roof and it doesn’t leak even when not finished correctly. 

 

Do you have a pic

No, I have a lead flashing with a lead upstand. you're expected to use a secondary storm collar. I can't recall why the rubber all-in-one flashings weren't an option for me though?

 

No pic of mine, but I'll try and get one over the weekend. Hopping on the roof is tricky at the moment as I'm 6 days post surgery. ?

Why not get a rubber one and cut the aluminium bit off and just use the rubber to pull down and sleeve over the lead upstand.

My lead flashing came with a suitable "Chinaman's Hat" that slides over the flue, slides down onto the top of the flashing and clamps to it.  I also sealed the gap between the flue and the "hat"
