I ordered the 14’ x 20’ shade sail that arrive in about a week.  It is made out of thick density plastic and water resistance.  It has 95 UV blockage from the sun.  The hardware came with the sail.  We are going to attach it to 2” x 4” posts after the cement dries.   The grill and table will go under it.   I can’t wait until it’s done.  If there is a hurricane, you could also use the sail to cover the leaks in the roof, then back to the shade.
