Repairs to edge of roof

Hi all,
Firstly,
After storm Arwen, a couple of tiles were damaged by uplift.
18 inch square hardrow slates "half tiles" on the edge so 18x9 inch.

I only had 1 spare so would it be ok to leave the other in place? Sorry I thought I had a pic, it's more 9x9 and the bottom edge is flush with the bottom edge of the full 18 inch Square tile above, and exposing more of the full tile below, but crucially no gaps for water to get down into roof . Should I still replace it?


Secondly, is their any good dry edging product I can fit?
Pic attached.
I've seen other houses with plastic sections, but have still been blown off.

That's because dodgy cowboys have fitted them.

Our latest job...
...has dry verge and dry ridge. You leave the battens overhanging the fascia by about 30mm (depending upon product) and fix a STAINLESS STEEL screw into the end of the batten. These don't blow off - ever.

Cheers. Battens don't protrude though, , probably why the cowboy eforts blew off. Is there anything for retrofit?

It's always difficult locating the centre of the end of a hidden batten successfully. That's why they are left protruding. I'm pretty sure there are deeper face fixed (fixed into the fascia) dry verge, but these are even uglier than the others.

There are continuous linear verge products out there but I've not used them.

Thanks, could leave the half tile that should be 9 inches wide and 18 inches long but is 12 inches long?, The bottom edge is flush with bottom edge of tile above and exposes the lower tile by 6 inches. No where for water to get between tiles
