I grow some of my roses in pots of various sizes. It gets pretty hot here but it works well. There is a whole forum devoted to container gardening and they have a lot of ideas and experience, but I am not sure many grow roses in pots.

It helps to mulch plants in pots. Maybe if you grouped some other sorts of potted plants around your roses that would help to shade them. I'd just give it a try. Many roses seem to do better in a pot. I don't bring mine in for the winter even though temps were freezing for two solid weeks last year. I didn't get much damage at all.

Thanks--Were they Tea Roses? from my understanding, they're more fussy and delicate--but Oh, I love the shape of blooms.
I thought of grouping Herbs around them.

You might need to wrap the pots in insulation of some kind to keep the roots from freezing in bad weather--how cold are your winters?

Well, this is a abnormal year, next week, -4. I thought of making a "sleeve" around the entire thing, of tar paper, and filling with hay.
I've always had pots om my deck--the self-watering kind, but I'm now unable to move them inside for winter, and thinking of the most beautiful thing I can grow, and not have to be moved.

I have a wrap around deck and have a number of container plants sitting on it - including roses. Here are a few tips I have accummulated over the past 15 years:
1. Use an appropriate sized pot - large does not mean better if your rose is still small - better to pot to an appropriate size, and pot up as the plant gets bigger.
2. The soil can get really heated up if exposed to direct sun, especially the containers are black in colour. I mitigate this several ways - most of the containers are put into decorative wooden containers; for the rest, I line the inside of the containers with something insulating (those foam sheets used for packaging are useful, as are discarded insulating blankets for water boilers) before potting up.
3. Depending on the size of the pots, the potting media deteriorate to a point which will affect the health of the plant. I report containers 5 gallons or smaller once every 2 years, containers 7-20 gallons once every 3-4 years.
4. It is useful to place the heavier containers on casters. I make these by retrieving wheels from throw away office chairs and install them into 2 x 4's. Those have saved my back many times over.
5. Know the weight limit of your deck. A large container can get really heavy when wet.
6. Nutrients leach out quickly in containers irrigated by drip - use a control release fertiliser, or install a siphon on to your drip system to deliver soluble fertiliser with the watering.
7. You will be surprised at how much higher the temperature is close to the house. When temperatures are forecast to dip below -5C, I bunch the containers right near to the house and use insulation polysterene sheets to protect the containers.

There is nothing more pleasing than bringing one's garden on to the deck. Enjoy!
