I had already 2 of them in pots last winter (although the pots are placed near the house's wall) and I had no problems at all during the winter. The other 4 in pots are not so repaired because they are placed nearby the fence, so they should suffer a bit more the low temperature... so maybe I will have to cover them (?)

If you have hybrid teas surviving -10 F, you were extremely fortunate.
If ground never freezes in the pot due to only brief cold snaps, with the pots next to the house, you are still pushing how good your fortune will be.
If the pot freezes, dead roses.

I have not covered my roses often after hard freeze low 20 degree weather in the fall, but they were covered with in a few weeks.
They did just fine.
At the same time in the past, I uncovered my HT early in the year due to very warm weather very early but then low 20 weather came for days.
I lost a lot of roses due to uncovering them too early in the Spring.
