In hurricane design, shallower than 30 degrees makes uplift a consideration.

Enginoids also like 30 degrees for roof slopes. Steeper than 30 degrees  
and live loading due to wind becomes a governing factor in the structural  
design --shallower than 30 degrees, gravity loads govern -- 30 degrees is  
the sweet spot between the two and is structurally very efficient.
