The answer to this question is very telling, in terms of the quality of your roofs protection to your property.
If your Roof is more than 20, but less than 40 years old, you probably have roofing felt underneath your Tiles. It is more than likely that the felt you have is the old Bitumen based Roofing Felt.
This type of Felt rots away after so many years of minor leaks. If the Roof is older than 40 years old then there is a chance there is NO Roofing Felt at all.
This means that if just one Tile should fall or break, you will now have a Guaranteed leak...at some point.
So, if your Tiles are less than 20 years old, they may be able to be used again. If they are older, then the chances that are you need a New Roof.

Additional to the traditional mortar that fixes Ridge Tiles to a Roof, there is now Dry Ridge and Verge Systems, which mean...No Ongoing Maintenance!
They are mechanically fixed to your Roof and do not fall off because the mortar has degraded over time.
All Ridge Tiles that have to be replaced, now have to be Mechanically fixed, even if they are installed using Mortar.
Re: Code of Practice BS5534
A new code of practice that details design standards, performance and installation of pitched roofs and vertical cladding using slates, tiles, shingles and shakes, as well as their associated components, has been published.
You have until February 2015 to start following the new standards outlined in the new BS5534 Code of Practice: Slating and tiling for pitched roofs and vertical cladding, which was published in August 2014 by the British Standards Institution.
Ridges and hips - In future you are likely to be asked by building control bodies how you intend to meet these new requirements. Although you do not have to use dry fix systems, you will have to demonstrate how you can effectively fix ridge tiles when using mortar.
Fixing of roof tiles – This needs great care as there are a number of proprietary systems available, but beware as many of them are specific to particular makes of tiles. It will be up to you to demonstrate you have the correct fixings and numbers for the type of tiles you intend to use.
Roofing underlays – They are prone to stretching and ‘ballooning’ under wind load. This can cause the tiles to have greater wind loads applied to them than their design permits. The new standard for underlays will test against this issue. So be sure it has been tested to the new standard and clearly identified as being suitable for the site location and batten gauge in question.
