A Rustic Shed-Hut-Shelter

Building Rustic, 2012

For a gazebo or a shed, what are the roofing options?

Put another way, what's the invitation, the message of certain roofing materials?
Tar Paper? Cedar Shakes? Slab Wood? Reclaimed Corrugated Metal? Clear Corrugated Polycarbonate?

Each choice has an implicit set of associations, guidelines of what to expect.   
What does a clear polycarbonate roof "say/" Hey, lie on your back and look up?

What does a split cedar shake roof say?  Wow is that expensive!
