I'm going to replace the boards on my front porch with composite decking.https://drive.google.com/open?id=1-shETpCk0e4_3U57D-QtoSiGVaSIlyBT

My goal is to use fasteners between the boards to hide any screwheads. As you can see in my pic, the first board on the porch overhangs by .5 in to create a leading edge to the porch (see pic)https://drive.google.com/open?id=108r6oge-3N2QEHJseGkLwYIEKe8CaxyI.

Since this would be the first board, are there fasteners I can use with this to fasten this board without revealing any screw heads? Would I have to glue this last board? Thoughts?

We have always been supplied screws with a tiny head and matching colours for the boards that need to be screwed down.

I'm not sure of the composite screw holding power but maybe 2 Kreg screws into each joist from the bottom would work.

The leading edge board has always been screwed down from the top, with those hidden fasteners.

If I were wanting to hide the screws on the leading board, I would use a 2 phase way.

first I would use a thin bead of PL Construction adhesive on the top of the rim joist, and the field joists.
Place the board, then get underneath and use L brackets (1" 0r 2"), and short panhead screws from underneath to solidly anchor the leading board.

I have always just screwed from the top though, telling the home owner there was no way to hide the first edge screws.

I guess someone cut router key slots and slide the board onto the screws.

Unfortunately, I won't have any access to underneath this board. I was planning on replacing the board starting with the first board closest to the house and then working back toward the edge of the porch.

Does the composite have a T&G joint to lock together?

What are you going to do about draining snowmelt without a space between the planks?

How about placing the edge one first, then working from the structure to the first plank?

Always start on the outside and work in because this can happen
