kubernetes - Multiple installations of application with ClusterRole fails

Question

I'm creating a small application which will listen for changes on various resources through the API. For such an task it needs permissions. So I thought I'd create a ClusterRole

{{- if not .Values.skipRole }}
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: {{ include "kubewatcher.serviceAccountName" . }}
rules:
  - apiGroups:
      - ""
    resources:
      - pods
      - events

      - namespaces
      - services
      - deployments
      - replicationcontrollers
      - replicasets
      - daemonsets
      - persistentvolumes
    verbs:
      - list
      - watch
      - get

  - apiGroups:
      - batch
    resources:
      - cronjobs
      - jobs
    verbs:
      - get
      - list
      - watch
{{- end }}

I also created a ServiceAccount

{{- if .Values.serviceAccount.create -}}
apiVersion: v1
kind: ServiceAccount
metadata:
  name: {{ include "kubewatcher.serviceAccountName" . }}
  labels:
    {{- include "kubewatcher.labels" . | nindent 4 }}
  {{- with .Values.serviceAccount.annotations }}
  annotations:
    {{- toYaml . | nindent 4 }}
  {{- end }}
{{- end }}

And finally ClusterRoleBinding

kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: {{ include "kubewatcher.fullname" . }}
subjects:
  - kind: ServiceAccount
    name: {{ include "kubewatcher.fullname" . }}
    namespace: {{ .Release.Namespace }}
roleRef:
  kind: ClusterRole
  name: {{ include "kubewatcher.serviceAccountName" . }}
  apiGroup: rbac.authorization.k8s.io

My application can interact with the API and everything seems to work just fine. However when I install another instance of my app, as I'm doing when I'm developing it further, I get the below error message.

Error: rendered manifests contain a resource that already exists. Unable to continue with install: ClusterRoleBinding "kubewatcher" in namespace "" exists and cannot be imported into the current release: invalid ownership metadata; annotation validation error: key "meta.helm.sh/release-namespace" must equal "kubewatcher-dev": current value is "kubewatcher"

The second instance is installed using the below command where I thought --set skipRole=true would let me bind to the already present ClusterRole

helm install kubewatcher --namespace kubewatcher-dev helm/ --set skipRole=true

Am I on the right path? Is there a better way? I tried to post the relevant parts of my code, please let me know if I should post additional parts
