Need some advice on my roof

[jayinwww]

I have two questions, does this picture show that I need to get new shingles?

My second question is, should I be worried if there is a wave in my roof...

1. Your shingles are well laid out and in good condition.

2. Notice that the ridge and RH verge is also "wavy"

3. Difficult to answer perhaps, but did you see the sheathing being fixed?
If the sheathing was incorrectly fixed ie.with joints/edges non-staggered, and nail size and nail schedule (screws are best) also incorrect, then thermal conditions could move the whole roof panel.

4. Correct 3/4" T&G ply (or at least 5/8"), i should imagine, is required in Alberta.

5. Rafter and ridge section sizes must be code or they might sag.

6. Excessive moisture conditions in the loft?

7. Which compass direction do the pics face?
What is the condition of the other side of the roof?

8. Are all the ceiling joists below the attic in position?
