Long side of plywood horizontally. I use locking clips between all rafters (this stops bowing and gives strength) and stagger all seems, and I cover all seams with a 4in wide weather barrier self sticking tape.Gable and eve sides and around breather vents and chimney and valleys get a ice/water shield barrier (36inch) in snow country and 24inch in warm. Something like a roof you do the best job once and no worries for 20-30 yrs.
The best thing is plywood not cdx for a roof and is against codes in a lot of places.

How do you install a sloped roof over an extisting flat roof?
You cut rafters, brace them as needed depending on the span and shingle it. I put one on a friend of mines. I cut the outside ends of the rafters at an angle so that I didn't need to change the fascia. Lay a 2x6 flat on the existing roof to run the braces down to. Your roof may not be flat but have a slope one way on it so you will have to take that into consideration for the peaked roof. He had a slightly sloped roof with tar and gravel on it and at the time I was able to put a pitched roof on for less than they wanted to re tar the flat one.
If warped 1X8 boards have pulled away from the studs on the roof can they be repaired or should they be replaced?
I assume you mean the sheathing on the slope of the roof that the roofing is nailed to. It is unlikely you could get them to lay down flat enough to have a smooth roof when finished. Any dips between rafters is going to show through to the shingles.
How do you build a roof?
Before you begin, it is important for you to sort the design and then get the necessary permits from your district council. Now, if you are planning to rebuild the roof, then you need to start by framing it. Order the trusses for the design you made or acquired. The measurements need to be exact and the trusses can be expensive. he information you will need when ordering trusses are Slope, Size of rafters Spacing of rafters Length of overhang Location and size of ceiling joists Size of ridge beam and any other bearing beams and Load Weight. Inspect the wood when you get your order to make sure it is adequate. Follow the design specifications from the blueprints and complete the framework. Next, you need to sheet the roof. Make sure you start to sheet the roof from the bottom and make your way up. Use the nails and nail the plywood to the frame of the roof. Lay out once side at a time, and cut the plywood to fit on the edges.. Now, apply the felt paper on the roof, To do so, get the tar paper and have it ready to go. Roll the tar paper across the plywood of the roof until you make sure it is completely covered in the tar paper. Finally, you need to apply the shingles. Shingles are mainly used to protect the roof from rain water. First, drag the bundles of shingles to the roof. Use the nail gun and start from the lowest corner. Next, start nailing it the shingle 1 on each sides. Work you way until one side is finished. Go to the beginning and add next layer. When you have finished with all sides of the roof, you can use single shingles to shingle the corners of the roof. Again, start from the bottom and work up. Hope this helps.

First, mark the roof with chalk lines at intervals. You want to make sure that your plumb lines are straight. Lay your first shingle butted up against the outside of the roof and overlapping the starter strip. Nail it down, with one nail at each corner, just below the asphalt line. Lay the next shingle down, and nail it down. Continue to the end of the roof.
Have an area 40ft by 60 ft want to cover it with plywood how many pieces do you need?
75 pieces (i.e standard size (4'x8') plywood sheets) (5 rows x 15 columns. Each row will consist of 15 sheets that will be 8'x60'. Each column will consist of 5 sheets that will be 4'x40'. 1. Lay the first column (5 plywood sheets) lengthwise (8') along the leftmost edge of your 40 ft area. 2. Lay the remaining columns of plywood sheets in the same manner to the right of the first 5 sheets. Solution Method: 1. Calculate given area: 40' * 60'= 2400 SF 2. Calculate plywood area: 4' * 8' = 32 SF 3. Divide given area by plywood area: 2400 SF / 32 SF = 75 plywood sheets.
