The type, quantities, and condition of the various materials which are contained witl>m <br />the roof assembly.. <br />b. 'The condition of roof substrate (deck) shall be dctermined and documented at the <br />location of the core sample taken. <br />Written and p~hotogrsphic documentation shall be provided to illustrate the above factors. <br />4. <br />a. Aa examination and calculation of the existing drainage integrity and capacity small <br />be made and compered with the actual existing requirements, <br />b. Calculated documwtatbn of any dead load contnbution by ponding water sha11 be <br />performed. A roof plan lag approximate sme and location of drainage <br />deflcimcies shell be inch>ided. <br />5.
