Your stated goals are doable. I would suggest you be prepared to place as much
or more importance on the location of your antenna(s) as the choice of antenna. The antennas(s) will need to be up in the clear, unobstructed by nearby trees and buildings including yours.
I would consider using a tripod and 10' mast at the peak of the roof. However I would want to prove I had a usable signal before drilling into the roof.
Consider the combination of the Antennas Direct DB8e (UHF) + Antennacraft Y10713 (High-VHF) + RCA TVPRAMP1R (preamplifier).
Point the Y10713 at 340° (compass) to see real CH 10 & CH-13 (CBS & PBS).
Though they can be adjusted to aim in different directions, start with the DB8e panels facing the same direction. Face the array toward 330° approx. adjust both aim and panel alignment to maximize your reception.
