MVC 5 AddToRole requires logout before it works?

Question

I'm finding that if I add a user to a role in ASP Identity, it doesn't take effect until I log out and log back in. Is there something I need to do to refresh a user's roles without forcing a user to log off first?

Here's how I'm adding the user to the role.

var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
var userId = HttpContext.Current.User.Identity.GetUserId();

userManager.AddToRole(userId, roleName);

Then, almost immediately, I redirect the user to this action method. I can tell in the database that I've been added to the correct role, but MVC still redirects me to the login page. However, if I log out, log back in, and attempt to go to this action method, it works just fine.

    [Authorize(Roles = RecoveryStandardRoles.ServiceProvider)]

    public partial class CertifyController : Controller

{
    #region Public Methods and Operators

    public virtual ActionResult CompanyProfile()
    {
        return this.View();
    }

    #endregion
}

Thank you for taking time to look at my question!

@kevin-junghans your answer lead me to the correct answer. This code shows how to add a user to a role in MVC 5 and to have that role automatically take effect.

var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
var userId = HttpContext.Current.User.Identity.GetUserId();

userManager.AddToRole(userId, roleName);

var authenticationManager = HttpContext.Current.GetOwinContext().Authentication;

authenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);

var user = userManager.FindById(userId);
var identity = userManager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);

authenticationManager.SignIn(new AuthenticationProperties { IsPersistent = false }, identity);

MVC5 register new user, assign role and activate user with role WITHOUT logging off and back on by using :await UserManager.AddToRoleAsync(user.Id, "Role Name")

if (ModelState.IsValid)
{
    var user = new ApplicationUser() { UserName = model.Email, Email = model.Email,StandName = model.StandName,FirstName = model.FirstName,LastName = model.LastName,CellPhone = model.CellPhone,Supervisor = model.Supervisor};
    IdentityResult result = await UserManager.CreateAsync(user, model.Password);

    var roleStore = new RoleStore<IdentityRole>(context);
    var roleManager = new RoleManager<IdentityRole>(roleStore);

    var userStore = new UserStore<ApplicationUser>(context);
    var userManager = new UserManager<ApplicationUser>(userStore);


    if (result.Succeeded)
    {
         ***await UserManager.AddToRoleAsync(user.Id, "Users Tammy");***
         await SignInAsync(user, isPersistent: false);
