I've godaddy asp.internet hosting. Each time I upload the build, it’s a manual laborious task of setting write permissions(to folders) with the web interface.

Is something I'm able to automate? What are the nant /script tasks that can perform this?

NAnt <attrib> task can perform this.

<!-- readonly="false" is default - for clearness only -->

<attrib readonly="false">

  <fileset basedir="C:foo">

    <include title="**/*" />
