I was looking for manufacturer data sheets to confirm the SRI for Zn-Al coated roofing (Silver color) but in Sri Lanka the suppliers do not have that information available. Can you please tell me if it is a must to submit the data sheets or submitting photos of the roof will be considered enough? There are some typical SRI values given in the LEED guidebook that I can use for calculations. Thank you.

Unfortunately you do need data sheets that are specific to your product - photos are not adequate. Not all light colors are necessarily high SRI (though most usually are), and some high SRI products are not very light. SRI used to be somewhat hard to get in the US too, until architects started asking for it. The market has since adjusted, but it took some time. Sorry to not be of more help.
