@Bliss @amarand I'd say both of you are likely right here. It's an apartment building, I'm on the second floor. The walls have steel in them from what I understand? We are in a very tight dip in, and I wouldn't say it's mountainous, but definitely a very roughly and hilly area. My carrier is Koodo, I should have 5G signal strength but no matter where we are in the house, it's difficult to get a consistent signal. Half the time my chair in the living room gets a signal, half the time it doesn't.

I suggest you download WeBoost or OpenSignal 4G/5G app to analyze your signal inside your home and on your roof to test for your cell signal. If its -60 dBm or a higher number, an individual (personal) antena on the roof may not be the best solution.
The residents in my building chipped in & leased a commercial Antenna to serve everyone in the bldg. I also opted to have cable wifi. Despite that I still needed an indoor signal booster because my apt is 12 stories from roof.
