Even though this tent is not recommended for the roof, I have secured it and am delighted to use it every morning for a bug free, outdoor meditation session. I ordered the 6x6 tent which is a perfect size for my purposes. I secured a flannel backed tablecloth over the top because it is not "rain proof" and with early morning fog, there are droplets that penetrate the roof. This works fine. I have also hung a curtain to block the sun on one side. I'm very happy.
