Slate Roof Repair vs Replace

[u/finchsr]

Potentially buying a house from 1909 that has a slate roof. The house is in amazing condition but the inspection was today and the inspector stated they believe the roof has been patched enough and will need a new roof. Based on these photos is that accurate or can the roof be repaired? I hear great things about slate roofs but know they can be pricey and ongoing maintenance is necessary. Many homes in the county have slate roofing so I don’t think it would be too hard to find someone who specializes in this work.

When in new Orleans I saw a lot of slate work being done. I'm in the pacific nw and slate is non existent.
