I've been intending to install dry verge caps for a while but thought I'd get a couple of firms round to give me a quote to see if diy was worth the effort.
One of them told me they could nail the caps into the ends of the laths through the mortar that fills the gap between the ends of the tiles and the asbestos board underneath. The other insisted that the end tiles had to be removed, additional 'lath extenders' installed, the mortar replaced and the caps fitted into the extenders. So I'm confused.
Clearly the second method would be more complete, but is it totally necessary?
Does any missing mortar have to be replaced/re-skimmed?
Just how much loading is there on an individual cap when they are interlocked?
We have the equivalent of five gables (98 tile ends) so there's a lot to do. Firm number one wanted £800, number two wanted £1800.
Anyone any thoughts on this, including diying it?
TIA
