Creating a roof with un-even walls

Hi Everyone,

Im trying to create an arched roof where the walls on either side aren’t the same and the roof also isn’t the same height throughout as its on a slope. Tried the ‘follow me’ tool but that only followed one side so it didn’t line up on the other side.

Any help would be massively appreciated. Ive attached the file for reference.

Thanks all,
