I have just gone through this pain myself. It actually turned out to be pretty simple. Just extend IdentityRole with your new properties.

public class ApplicationRole : IdentityRole
{
    public ApplicationRole(string name)
        : base(name)
    { }

    public ApplicationRole()
    { }

    public string Description { get; set; }
}

Then you need to add the line

new public DbSet Roles { get; set; }

into your ApplicationDbContext class like this otherwise you will get errors.

public class ApplicationDbContext : IdentityDbContext
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {}

    new public DbSet Roles { get; set; }
}

thats all I needed to do. Make sure you change all instances of IdentityRole to ApplicationRole including anything you are seeding. Also, dont forget to issue a "update-database" to apply the changes to your DB. Any existing rows in there won't be seen by your new RoleManager unless you have the "ApplicationRole" set as a discriminator. You can easily add this yourself.
