Note that "Low-Slope" is probably not the table that you want to use:

Table 1 – Specifications for Low-Slope Roof Products

I just used that as an example of the SRI and aged SRI. Most roofs will be high-slope >3:12 pitch

DO NOT post their SRI numbers or better yet, their aged SRI numbers

I never had any difficulty finding that information on a roofing product I was interested in. Truth is that most companies which make or sell roofing are going to use materials or coatings from a yet smaller number of suppliers. Nearly every reputable manufacturer is going to have a cool roof product of some kind.

They literally have to, unless they want to write off the entire California market, since there are minimum SRI specs under Title 24 for every CA climate subzone. 

Last I heard CA still held double-digit percentage of the US housing market for new construction (not that I've tracked it very closely.)
