What does it mean when the roses are sprouting red branches or canes? It looks like it will bloom but it just grows more and does not bloom. The roses are 8 years old and have bloomed perfectly for the last 8 years.

John, where is your garden? It is not unusual for new growth on roses to be richly colored - - reddish or burgundy are common. Not flowering, however, can indicate a numbers of problem, from too much shade and soil fertility problems to rare but serious insect infestations. If you garden in the eastern US, especially in Pennsylvania or Maryland, rose midge can prevent bloom and must be treated with potent pesticide. If you look at the growing tips and find that they are tiny and blackened, then rose midge may be to blame.

What do the new canes look like? Are they thin and plentiful, in a bunch?

You either have new main canes/basil breaks which should be substancial and appear sturdy. Or the root stock is suckering. If the foliage doesn't match what you have, or it is coming up tiny it's the root stock. Dig down carefully to the bud union (nobby part where the canes come from) if the new growth is coming from under it, sharply yank down to remove them. Or if this the only growth, and you don't mind a once bloomer.. let it go.
It is probably either Multiflora or Dr. Huey
