It attenuates wifi pretty substantially, I assume the same with TV signals.if you got a metal roof and the antenna inside the attic, the metal roof will cancel, reflect any signal
I put an external antenna on top of the shop's metal roof. Not a huge one, but just getting it outside the structure provided a huge advantage.
There is an "antenna calculator" that will give you an idea of nearby signals:

Which broadcast channels can you receive for free? It's time you cut the cord!
I wired everything for co-ax (antenna) and then I bought a DVR (Amazon at the time, discontinued). Basically the DVR in the shop manages all TV reception (and recording) for everything in my house and shop. Way easier than doing it the old fashioned way and you can skip commercials!
