Bench Basics Part 4

 
Back to Bench Basics Part 3
For the sides we chose corrugated roofing material (plain old tin roofing).  We cut the 8' lengths to 4'.
Overlapping a single valley we connected a 6 panels to make a 12' length using pop rivets.
One long piece.
Setting the entire panel in place, we clamped it so we can continue working.
Pre-drill some 4' sections of angle aluminum.
Peel back the liner in the non-computer side.
Secure the angle in place.
Secure the tin roofing to the angle using pop rivets.
Put a screw about 2" from the bottom and work your way around, putting a screw every other valley.  Go about half way around and stop.
Put the angle in the other corner (as shown above) and secure some clear corrugated roofing to it with pop rivets.
As before overlap it with the tin roof a single valley and rivet it to the roofing.
Put in the lower screws working from the clear towards the corner, and put in the other screws towards the corner.

We estimate the curve in the first corner, and work to pull the entire sheet tight in the second.  This makes it so we do not have to cut the length of the sheet to get it to stop where we want.
For the front edge we found some drip edge flashing.
Lay a bead of caulk down BEFORE putting the flashing on, this allows it to squeeze out and form a water proof joint.  Wipe away the excess caulk.
A row of screws completes the front edge.
