Repointing to ridges, verges, valleys and abutments where the mortar has cracked out.
Mortar holds a surprising amount of a traditional roof together, at the ridge, along the gable verges, down the valley edges and where the roof meets a wall. It is also the part that frost gets into first. Repointing those lines is a modest job that prevents tiles working loose and water finding its way underneath.
Loose and cracked material is raked back to something sound. Pointing over failed mortar just puts a thin skin on the problem.
The surfaces are damped so the new mortar cures properly rather than drying out too fast and cracking straight away.
A mix suited to the roof and the exposure. Too strong a mix cracks away from the tile; too weak and it washes out.
Any verge or ridge tile that has worked loose gets bedded back properly at the same time, and clipped where the exposure warrants it.
Joints struck neatly, and the debris cleared out of the gutters before we leave.

Well done, many years. It depends heavily on exposure, and a gable that takes the prevailing wind will always go before a sheltered one.
It is worth considering. Dry verge caps clip on mechanically with no mortar to crack, and on an exposed gable they are usually the better long term answer.
Not in frost. New mortar that freezes before it cures will fail, so we would rather wait for the weather than do it twice.
Not immediately, but it is the start of a chain. Mortar goes, tiles work loose, then water gets in. It is much cheaper dealt with early.
Yes, though a chimney stack is its own job. Have a look at our chimney repairs page for what that involves.
