    curring cracks are longitudinal to the longest span and they are parrallelle to one and another. The kind of cracks that you are talking about are more of the differential stifness kind, ( bad compaction or big debris on top of the fill that created the radial craks). Have the house setteled a bit? with pictures i could tell you what is the probable cause of the cracks.

    id="left"> Sorry about my english! I'm french. You're rignt about the bad wormanship. À slop should always run to the drain ! Period. About the the ponding, I think it's best to evaluate the situation befor jumping to the chart or rule of thumb. 3/4 on an inche means 4.0967 pound per square feet, add a dynamic force to it and worst case senario you're up to 6 or 7 pound it represent lest than 20% the total calculation load for your roof . if the roof is well design this accumulation is taking into account. See insted the deept of the roof joist and see if it can take the load.
