While replacing windows in some dormer roofs for a customer I have discovered there are no lead soakers fitted, just roofing felt run around onto the dormer cheeks.
Construction is pitched roof, Kent peg tiles on battens and felt. Side of dormers are chipboard (all rotted away) with expanded metal attached and rendered over.
The old roof felt has degraded where it returns around onto the dormer sides and allowed water to soak behind the rendered cheeks into the chipboard. This has now all been replaced and the cheeks are now external ply.
The roof has very steep pitch, and as the windows are not tall the side cheeks are small with a return of only 250mm at the top, so instead of re-rendering I intend to use lead. I have installed traditional soakers many times before but so far always abutting brick where I have pugged them into the mortar joints.
So, how do I attach the soakers to the ply side cheeks of a dormer when that also is covered in lead.
I am guessing that first I simply tack the return of each soaker to the ply, working from bottom to top as I work up through the tile rows, and then i fit the triangular lead to the dormer cheek which will cover these soakers.
I will tack a lead strip under soffit of dormer to fold back over top edge of side cheek lead to hold it back, return side cheek lead around face of dormer and cover it with timber cheek.
But how do I finish/hold back the triangular side lead where it runs up the pitch line of the tiles over the soakers?
Or am I completely on the wrong track?
Thanks Steve.
PS, I would have a roofer do it, but I cant get anyone next week that's interested, and as I have a job in progress I have got to do it myself.
And I just read another thread about leading on dormers and the issue about HSE was raised. This job is all scaffolded out and PL insured.
