I would suggest using a strong primer from the zinser brand

You need to scrape off the flaking , peeling stuff then apply a coat of the primer which is a water based product but is the real deal when it comes to a base for top coats

It can be tinted so if your slates are going to be a mid red, you can add the appropriate colour so you don't have to do coat after coat of your chosen finish

The zinser primer dries very quickly ....if it looks patchy consider putting two coats on before your top coat .......

Make sure that top coat is suitable and not cheap crap as your roof really takes the sun and rain and this is a job you want to last

As I said it's intensive work and may cost you several grand
This should be your base coat

You can apply it by brush or sprayer
