The pointing at the roof edge is a part of the 'Dry verge' which is the aspestos strip under the edge that lies on top of the bricks to stop wet getting into the brickwork. This only needs pointing if loose and falling out. Removing it will only disturbe the edge tiles and youi will probably find the *battern ends rotten. (*Houses over 30yrs)
If plastic 'dry verge' caps put on correctly, the first two tiles are removed up the whole side, new battern ends added, membrane and then the caps. Most companies however only glue, nail or screw the caps to the existing concrete and a quick cosmetic fix. Prices range from £5 to £15 per cap if a company does them. Aveage 5mtr roof side = 15-16 caps. Not really a DIY job as the ridge can be 9-12 mtrs above ground and most domestic laddders will not reach. I have seen roof battern (2x1 treated), attached along the whole length of the verge, and caps simply screwed to that, though they did not overlap the tiles fully, they were very secure.
Good Luck
