Dry verge caps are a really good system!
Dry verge caps they do away with the use of cement mortar on the gable end.
And prevent storm damage when fitted correctly, we do come across dry verge installation problems when fitting dry verge to old roof
most common installation mistakes is the starter kit for dry verge units for the first dry verge to connect with this is fitted to the fascia and stops birds and insects entering the eaves but the main reason is to stop the wind caching the first cap, and damaging it”
Weve been to so many property’s where the dry verge caps have ( blown off )… by the wind and you’re left with broken cement pointing on the verge where the caps have been screwed through into the ends of rotten tile batons,
This will cause water ingress through the cracked mortar… and possibly missing tiles with the next strong winds”
and then it’s on the phone saying,

To get the real benefit of the dry verge system
And fitting dry verge to an existing roof
They need to be installed properly by removing two or three ridge tiles
take back three courses of tiles into the roof or to the second spar that runs from the ridge to the eaves. pictured
Replace the roofing felt. with a new good quality breathable felt and re-baton the verge leaving an overhang of 40m forMarley dry verge caps to fasten too,
If the tiles overhang more than 40m they will need to be cut,
Re-tile and set ridge tiles on a bed of cement mortar, job done!
they cannot be fastened through the existing cement although a lot of contractors will try to do exactly that”
they just wont last…
over 75% of new build houses are now fitted with dry verge caps in england and Wales,
Where as Scotland and southwest Scotland over 90% of roofing is already mechanically fixed OR fixed with mechanical fasteners
