Step Seven
OK, before it rains, let's put a roof on. If you haven't ordered your roofing yet you need to do so now. You will need 4 pieces of two foot metal roofing for the front, 48" long, 4 pieces 42" long for the back, and two 10 foot long trim pieces for the edges. And 200 screws, your choice of color. Also you are going to need a 25 foot roll of 1/2 by 1/2 galvanized wire screen for your Aviary front, vents, and roof vent so if you haven't got that yet go ahead and get it now also. OK, let's do it!
Take an 8 foot 2X4 and rip the corner off at a 45 like you did before. Install this 2x4 at the front peak of the roof, like this.
Now take another 2X4 and install it 4" down from the one you just installed, this will leave your 4" gape for the roof vent. Like this.
Now, while you have a nice big opening cover your just created vent with the 1/2 by 1/2 screen. Cut 4 pieces 6" wide off the end of your roll, so you have 4 pieces 6X24 inches. Staple these pieces on top of the 2X4s to cover your vent. Now take a 8 foot 1X4 and install it along the back wall at the roof line. Screw the OSB sides into the 1X4 like you did with the 2X4s but also screw the back wall of the loft to the 1X4 using 2" sheet rock screws from outside going through your outside 1X4 trim board, through the OSB, into the 1X4 being installed, like this.
Now measure the distance between the 1X4 you just installed and the 2X4, divide this in half, and mark each end of the loft. Install another 2X4 here.
OK, lets put some roofing on. I am not going to go into how to install metal roofing. If you haven't done this before ask at the lumber store where you bought it. Take your 4 pieces 42" long, start at one end, and install them fron the top of the vent 2X4, like this.
Well, the back of your roof is now done. We will add the trim later.
