Assuming the painting is fully dry, you should be able to roll up a canvas painting without issue. Do be mindful to check for existing cracks in the paint as this could be a problem if you then roll it up. Also look out for situations where the paint has been applied very thickly as again this is more likely to crack and suffer damage if rolled up. If you are ever in doubt you can take a photo and send to us before rolling up and we will advise.
