Hi datawiz, I just saw your post. A lot of suggestions will depend on what your growing zone is. This will make a big difference in which climbing roses will actually climb for you.

It used to be 6 but now it is warmer and is 7

Hello there :),

I would like to recommend Mel‘s Heritage rambler. If you do a search you will be able to see some good pictures. I am not sure your shed will be but it gets pretty large. I think awakening may do a great job as well.

They are both light colored. If you would prefer a brighter shade my raspberry cream t climbing roses gets no fungus and reblooms well even as a young plant. Raspberry only gets to maybe 12 feet only. Also Laguna is gorgeous and healthy.

I am in McLean Va

I'm going to think on this, but meanwhile you might want to check your Hartwood rose's blog for her suggestions as she live nearby-ish. http://hartwoodroses.blogspot.com

She has many climbers both on her fence and growing up an amazing arbor.
