Suggestions on sealing old flat roof pipe against brick wall

[steggles123]

All,

I have an old old flat roof with a soil pipe flush against the brick wall. Whilst it's probably not leaking I know it's not the best.

Any suggestions on doing my best to make it leaky-proof-ish?

I know the roof needs replacing but I am not in a position to do so as yet

Any ideas at all?

Kindly,

You can't make the pipe penetration leak proof when the roof is in such a state

Acrylpol (and flashband). Buy a big tin and do the whole roof.

Hi foxhole/woody.

Cheers for the input.

I assume you are referring to flashband adhesive tape?

For the pipe itself or on the brick behind it ?

I actually had a 20kg tin of acrypol and a large 1m wide of a competitors roof mesh delivered - I couldn't get a wide enough roll in fibreglass.

I intended on covering the full roof (3m wide x 7m long). My calculations were off with the acrypol I think I expect another tin.

Can either of you make it stop raining? Ha.
