 TAM shield. It's a synthetic underlayment. Yeah. And it's plastic. And they use that instead of felt paper. Yeah, right. It's synthetic. And it's actually an upgrade to standard 15-pound felt paper. And it's actually better than using standard felt paper under a roof. The reason that your roof is leaking now is probably not because of the TAM shield. It's probably because of something that went wrong with the repair. But I don't think it would have been the underlayment because that's actually pretty good stuff.
