how much damage?

Our winter has been really warm. My roses have all put out leaves. Then the temps dipped to the teens for two nights. I am new to roses and don't know what to expect--OR how/if my blooms will be effected... The leaves have not fallen off.

You may lose some of that new growth but it will grow back. The problem is when it happens repeatedly and the rose uses up all of it's stored energy on false starts. If it happens too many times the rose could just run out of energy and not come back. It will not effect the blooms other than maybe delaying them a little. Just leave those leaves on there and wait and see if they survive or dry up and fall off. Taking them off will just encourage your roses to bud out again and you don't want that until it is going to stay warm.

Relax until spring and normal spring weather arrives. There's nothing you should do now except wait. If buds get frozen, there are two dormant backups. The canes can survive down to the single digits and below zero. Where we make mistakes is trying to help Mom Nature. Roses have survived for hundreds or thousands of years without our help in all kinds of weather. Repair any damage this spring.

Mine all budded and several leafed out and then we also had weather in the teens. Surprisingly, they don't look like they froze to death in that cold snap (when that happens they appear to brown up and die and then the plant starts over with the next warming cycle).

At the moment they are just sitting there, the buds looking fine (maybe they are tougher than the leaves?). I'm hoping the cold was sufficient to check their exuberance but not kill them.

Karl is right, although it always pains me to watch them go through this--nothing to be done but see if/how many times they have to start over. I've had "third time's the charm" years previously, where I lost two whole rounds of extensive growth to late freezes before they made a permanent start. End up removing more dead in the spring and it reduces flowering a bit but yes, they do generally survive.

thank you, all. I don't see any real damage on most of them but a few are very dark but still look alive... I will sit back and relax... TY again...

The natural sugars in new growth provide a certain amount of antifreeze qualities that will protect new growth to a point.

those old leaves will probably fall off anyway, just because leaves have a life span too - lots of new ones will appear again. no worries.
