There are several virus that can affect roses. http://extension.umd.edu/hgic/virus-diseases-shrubs
Herbicide damage - It is possible that this may be herbicide damage especially if something was sprayed on the shrubs or nearby.http://extension.umd.edu/hgic/herbicide-damage-trees-and-shrubs
Rose rosette is a disease caused by a virus. Leaves are usually red and excessive pliable thorns, etc. If this is the case, all you can do is remove the plants. It infects the roots but not the soil. However, the vector, eriophyid mites, may introduce the virus to new plants. http://extension.umd.edu/hgic/rose-rosette-shrub
At this point, you may want to take cuttings from healthy growth. Take six inch cuttings and root in soilless mixture.
At this point, all you can do is prune back hard to healthy tissue. Keep watered.
Monitor the new growth to see if it is healthy.
