vfrdave Posted July 5, 2018 Share Posted July 5, 2018 How would you finish the render on these chimneys where the lead trays are. I can see the point of the folded lead but it doesnt exactly leave it easy or neat to render to. Could the fold be trimmed off and the lead meshed and rendered over?

PeterW Posted July 5, 2018 Share Posted July 5, 2018 Ideally you want to stop the render above the tray, then put new render below and dress the lead over it. TBH the amount of leakage on a chimney these days with a proper weather cowl on it is negligible and trays are rare to find - cracking of flaunching is more of an issue with older chimneys too, and its rare to see trays fitted to newer ones.

Advice welcome I cut my tray back to 50 mil flattened it to the block and put two wraps either side and meshed over the whole chimney Leaving the wraps exsposed As already pointed out very unlikely to get much rain down there In the unlikely event The weaps would let any moister out Link to comment Share on other sites More sharing options...

I have fairly beefy caps on the top of the chimneys now so as you say water is not likely to get down Link to comment Share on other sites More sharing options...

Would need to use stainless steel screws and SS or lead washers to fix the mesh through the flashing into the brick before rendering. Google found photos of something similar.. https://www.yelp.co.uk/biz_photos/ben-hockey-roofing-chalvington?select=_LLkfuZwwPUKDobw-N4RiQ Link to comment Share on other sites More sharing options...
Temp Posted July 5, 2018 Share Posted July 5, 2018 I'm thinking put the bottom of the stop bead about here... Link to comment Share on other sites More sharing options...
Temp Posted July 5, 2018 Share Posted July 5, 2018 Just a check but... Are there soakers under the lead and slate? Link to comment Share on other sites More sharing options...

I can understand the stop bead running in line with the pitch of the roof, but the horizontal one doesnt seem right when the render will continue below that stop bead or am I missing something.

Temp Posted July 6, 2018 Share Posted July 6, 2018 You could mesh and render right over the lead on the face but I wasn't sure how to do the corner where you have that small flap/triangle of lead. With a stop bead that bit of lead comes out from under the bead. If you render down to that triangle of lead and the lead moves I thought the render might crack in that area.
