my question is;
what should be used to repair it? what type of mix?

I used morter mix. It had been holding up after 5 years so far.

do i have to remove all the old mortor or can i go over the top of the
existing stuff?

Anything loose shold be taken off, or course. if it is solid, it gives you a
goodtemplate for hte contour.



i know that it should have pitch to it for water to runoff but
how do you trowel it for finish, are there suppose to be high *points*
where
the angles are from the four corners or can it just be a gradual taper all
the way around.

Mine is just tapered. As a practical matter, it does not make any
difference, just what looks good to you.

If you know it needs repair, why go through a winter where more damage can
occur? Freezing - thawing cycles can make cracks even worse.
