Install Satellite or Aerial on Roof

Hi there, this is just a fact-finding mission about how much it would cost to get someone to pop either an aerial or a satellite dish on my roof. The house is new, built in 2018, single-storey and I'm not sure what other details may be required. Mostly I just want to get freeview and the first indoor antenna I bought did jack squat. Would buying an aerial for the roof and getting someone to install it be cost-prohibitive, I wonder? Photo of my roof from the deck posted. Thank you for the help!
