How to redirect the users based on there roles laravel 5.1

Hello their i am using laravel 5.1 and i have problem with redirecting the path of user. i have a roles table, a users table and role_user table means pivot table. Every thing is fine nice but i failed to redirect the page of different user. . This is my User Model. I have not created any middleware

public function roles()
{
    return $this->belongsToMany('my\role');
}


public function hasRole($role) 
{
    if (is_string($role)){

        return $this->roles->contains('name', $role);
    }

    return !! $role->intersect($this->roles)->count();
}

This is my AuthController:

public function redirectPath()
{
// Logic that determines where to send the user
if (\Auth::user()->hasRole('GlobalAdmin', 'SuperAdmin', 'CompanyAdmin', 'GroupAdmin')) {

    return '/adminpanel';
    }

    return '/dashboard';
}

}

When i login as role globleadmin iIt works fine and redirect to adminpanel but when i login as another assigned role it redirect to dashboard. I did'n get it perhaps i passed arguments in authcontriller as: if (\Auth::user()->hasRole('GlobalAdmin', 'SuperAdmin', 'CompanyAdmin', 'GroupAdmin')) is incorrect. Please help me.

This is my route:

Route::get('/adminpanel', 'Admin\adminscontroller@index');

And This is my adminscontroller:

class adminscontroller extends Controller

{

public function __construct()
{

    $this->middleware('auth');
}

/**
 * Display a listing of the resource.
 *
 * @return \Illuminate\Http\Response
 */
public function index()
{
    return view('Admin.AdminPanel');
}

}

Thanks in advance.
