It depends on the color of the metal roof. A light colored metal roof will likely qualify as an SRI value greater than 29, a dark colored metal roof likely will not. For more information on specific products go to http://www.coolroofs.org/products/search.php and you can search for your specific products. You can also download a calculator that generates an SRI value based on solar reflectance and thermal emittance here: http://www.coolmetalroofing.org/elements/downloads/SRIcalc9.xls.

Thanks for the reply. Does the project need to use specifically these products given on the www.coolroofs.org webpage? We do not want to import metal roof sheets from the US, since we can easily find light colored metal roofs or coat them after installation (project is located in Istanbul). However, I really doubt that the manufacturer would have a cut sheet stating solar reflectivity and thermal emissivity.

Omer, you are not limited to products from the coolroofs.org page, but you do need to use products that can demonstrate with solid data that they meet the SRI specs. You could consider getting the local products there tested, for example.
