Cover the construction with a tarp?

[hahalj]

I am working on my storage shed (construction thread here) and am wondering how important it is to cover the build with a tarpaulin when I know it will rain? I build a little now and then mostly on weekends, but the roof will probably take a few more weeks before it goes up.

I have a tight tarpaulin that is sufficient, should I cover everything with this between building sessions?

You don't need to cover the wooden frame at all. However, you will need to wait until it is dry before you can start enclosing it from the inside.

I ended up putting a tarp over it anyway, it feels silly to let it get wet when I know it's going to rain and I can't build for a few days anyway.
