Attached you <br /> will Eind a oopy of the structural calculations whicli verify the ability of the roof � <br /> to support water up to the top of the parapet sliould tt�e roof drain bemme I <br /> dogged. Overflow drai��s are therefore not required. � <br /> i <br /> Good practice, however,suggests that some method of preventing this potential � <br /> storage of water be utilized. In order to do this,we will be installing a secondary P'tR'k���� <br /> drain with thP inlet flnw line located 2 inches above the.low point of the roof.
