Tv antennas can be any size to get reception.
It is important understand concept and then the actual fact and get the wording correct.

That said the Tv transmissions are so strong at your location that if the roof is not a metal roof , you can put the antenna in the attic or above the roof and the reception will be the same.
Here is the Federal Antenna Law that says yes you can , install , use , maintain , a Tv antenna of any size above the roof to get reliable reception.
Read this Federal Antenna Law and understand that it is written in your favor and provides for you concrete legal rights to , install , use , maintain , antennas and stops the antenna haters dead in there tracks.
