Lead flashing required over aluminum soaker?

Question

Hi, I'm currently having a new roof and porch put on, but am unsure about the finishing steps at the interface of the tiles and rendered wall.

The roof interfaces with two timber dormer cheeks, and one masonry dormer cheek, all of which will be rendered once the roof is completed.

Currently, aluminium soakers have been installed under the tiles, finishing against the wall/cheeks. My question is:

1) should a flashing now be installed on the wall/cheeks, overlapping/protecting the soakers, with the render then bought down to slightly overlap the flashing and the edge finished with a bell bead.

Or

2) Should the render bead be installed directly overlapping the soaker, and not bother with the flashing?

Have looked online but can't seem to find a definitive answer. I'm a bit concerned that without a flashing there's a risk of issues in the future which will then mean having to hack the render off!

Thanks for any replies.

Yes put the lead flashing on now and then put a render bead 1 inch and half or 2 inch from top
Of lead then render the wall.

Personally we would use wider soakers with a bigger upstand against the wall as alli soakers only have a 2"upstand making it hard to fix stop bead

Jordan · Answer

Yes a lead flashing should also be installed on top of the soakers with a minimum of 150mm up stand and a render bead 75-100mm over that

It would weather, providing the soakers have been fitted correctly.
For maintenance reasons it would be best to have a 6” flashing with a bead for the render, make sure you don’t put bead on soaker though, you don’t want holes in soaker & you may need to remove them at some point later !

Hi I would go with the lead flashing and be on the safe side , or you could silicone the aluminium soakers back to the wall giving extra precautions  if a leak does appear or do both , all the best Eric

As long as the soakers are under the bead it should be fine no need for a flashing you can install one but it a bit overkill
