Flashing question

[psmk2]

When i was fitting a new lead flashing round my chimney (flat roof)i couldn't get the flashing all the way into the channel. In some bits the flashing just sits flush with the channel. I have gunned it up with copious amounts of lead seal mastic and sealed it completely. Will this be enough to stop it leaking or will i need to redo the flashing.....it was my first ever attempt and whilst not pretty its far better than what was there as the previous flashing didnt come down to the roof

What channel, English Channel?

Channel in the masonry presumably. Got a photo?

In that case he needs an apron in the "channel" (aka joint) which drapes over the flashing upstand.

Or the channel was tight and it needs grinding out.

Was up today...the sealant is set so im just going to leave it and see what happens when it rains..i used no nonsense lead sealant and completely filled the joint
