Some asphalt shingle manufacturers will not warrant their product over any unvented system including SIPs , but you need to check with the mfg., Their claim is that they cook faster and degrade  10-15% quicker , although I don't know if they have really substantiated that claim. 
Last I knew Elk still warrants their shingle over SIPs and unvented roofs.
I do not know what kind of concern metal or cement tile over SIPs would be?
Gerard roofing, a stone coated steel shingle roof is approved over SIPs

Did you ever try to make a claim against a shingle manufacturer anyway? Good Luck!
