The roofline verges of houses near mine (mine included) protrude by
about 60mm from facias...
I saw one neighbour have a dry verge system fitted ... took several
days as as contractor trimmed back each tile and fitted the dry verge
system "properly" (attatched to ends of battans?)...
I saw another neighbour get their done in less than a day ... fitter
simply pulled off any metal tile clips on the verge... then pushed on
the dry verge cap and then screwed it on via a long screw through a
hole toward the bottom of the cap into the pvc fascia (couldn't tell
how deep it went (probably thru the upvc facia just into the wood
beneath)...
Fitter said this was a valid way of fitting them... it was certainly
quick! ..it did look pretty tidy... one screw per dry verge cap...
invisible unless you were directly underneath where you could see some
of the screw lenght as the cap wasnt flush with the facia due the the
depth of the tile overhang)....

Question ... is this a valid way of fixing dry verge capping?
It seemed firm enough to not be blown off by the wind... but other than
making the verge look prettier (than the cracked verge mortar) how
secure does the dry verge system have to be...

If it is this easy ... I could tackle that myself (whereas all that
tile triming that other neighbour had done put me right off)?
