He didn't need to hack off, just 'butter' a bit over the exposed

I've been on hundreds of roofs where that's been done and the new
mortar has come off and slid down the roof. The only way to do
ridges is to take the tiles right off, remove all the old mortar,
lay a new bed, then point up.

And if you must use mortar,

Er... are there many other options for a traditional house repair?

For ridge tiles? Plenty. They ain't load bearing.

Other than mortar what would you recommend?

Oh dear here we go again
You said 4 sentences up there ^

"If you must use mortar....."

I've asked what else you recommend & not yet had a constructive
answer from you. Never mind.

The modern way is 'dry ridge'. There seem to be plastic connectors
between the ridge and hip tiles that are nailed with aluminium nails
into the truss. Only the angled joint where a hip meets a ridge is
mortared.

The gable end of an unhipped roof can be done with special plastic
covers and no mortar is used.
