I am not able to pick-up your valley copper:
"20 ounce by 16" wide copper valley flashing".
When I order my copper from the local roofing supply, I should specify:
strip copper (in coil form)
and should I specify H01 (cold rolled, high yield)?
The guy tends to roll his eyes when I try to talk about ounces and the HO1. How do I make sure that I am getting the right stuff? And the guy wants to talk weight-- he sells 100lb pound rolls-- not length. Thanks

16" wide valley copper is good for 6" wide exposures with no V groove. If you have a wider exposure or a V groove, the copper should be at least 10" wider than the exposure and you have to add 2" for a V groove.
Most 100 lb. rolls of copper are 16 ounce soft copper. A lot of the sales people at roofing supply places don't know much about these sorts of materials.
All you need to tell them is that you need 20 ounce copper, 16" wide by X number of feet. They may not have it, but they may have 20 ounce copper in sheets that you would have to cut into strips. Otherwise, if you want to buy 20 ounce copper rolls, you'll have to get it from a copper supplier, not a roofing supplier. Try Copper Sales or Unimet.
