Sorry, Cameron and Clint, it is just not possible to accurately ID sempervivum from photos. They are too similar and too variable. They have been hybridized for more than 100 years as well, so tectorum, calcareum, etc genes are widely distributed throughout. So if someone gives you a no-id plant, it should remain a no-id in fairness to the hobby and its participants.
There are a few exceptions. For example, Sempervivum 'Oddity', S. 'Fame Monstrose' are distinctive enough to be easily ID'd. So is the plant in question S. tectorum? Likely not, but it might be a tectorum hybrid.
