I’m planning on using rain water off my garage roof the shingles seem to be 20-30 years old, my question is how safe is that water to use to water my veg. garden?

Using rain water collected from your roof in your vegetable garden is ok if you clean the barrel with a bleach solution and if you use it to water the soil, not the plant tissue. For more information, please refer to https://njaes.rutgers.edu/fs1218/.
