I have a similar question, our green roof covers about 4.97% of the site area. There is no turf grass and It received a water efficient landscaping credit under LEED NC.
My question is would a 4.97% be sufficient or do i need 5% exactly, and is their no other way to achieve this credit without hiring a landscape architect.

I couldn't say for sure, but with other credits (like LEED-NC SSc4.3) LEED does not allow you to round up. You could try rounding up, or tweaking the calculations to make it work, but be prepared to have it questioned during LEED review.There's no requirement to use an landscape architect to achieve this credit, but it can be helpful.
