Are you doing any weight/strength training? A few weighted calf raises can actually do wonders for tight calves, improving their strength will make them much more able to deal with the stresses of constant movement in running. Same with quads. Many more types of exercises for those.
Even just some raises on a step would be good. Hold something heavy or put something in rucksack etc. Some squats and lunges also good and easy to do without any equipment.
I found that strength training cured my tight calves much more than any stretching or foam rolling did.
