Building a room under an open deck so it is water tight?

Since you are installing decking planks above the membrane below, I doubt the Grace would suffer exposure issues, but covering was a good decision.
The extra yard gone is always a plus.

Thanks. I agree but the Grace had some wrinkles so there was some pooling of water. The Polyglass has a nice hard shell so the water runs right off!
