Pipe seal for flat roof

[Na1han]

Hi I want to run a 15mm pipe through a felted flat roof. Does anyone know of a collar or seal I can use to weather it?

Is there going to be water in the 15mm pipe at any time?

Yes it's for a tap inside the garage.

what about insulation then ?

I did come across them but it says they are for metal roofs. Have you used them on felt before?
It will be insulated and I'll install isolation and drain off for the winter.

Don't see why it wouldn't work, I'd probably get some felt and bitumen over the flat flange at the bottom to add an additional run off for the water .

Didn’t Madonna wear a pair in the 80’s?

Great cheers for the help all.

Can you not just seal around and use a talon collar? https://www.NoLinkingToThis/p/talon...xUTcPXLFK4SiKaeetgtsHHm7zYicSjWAaAmkmEALw_wcB

And of course insulation.
