Stone coated losing stone, having mildew

In getting estimates for metal roofing, I was told stone coated roofs have been known under certain conditions to lose some of the stones, (rain, cold). Also, that in humid climates such as in Florida, that I may still have a mildew problems. Can you tell me if these two problems are correctly stated and of concern to me. Thank you

Both of these questions, being particular to aggregate-coated products, could be best-answered, I feel, by direct contact with the manufacturers of such products. However, I will sya that these products are extremely proven in a wide variety of climates. Additionally, though, I must caution you that any surface outside can have biologiocal growth occur under certain conditions. This happens particularly when roofs are in dirty areas such as under or around trees. Dirt, sap, etc. from the trees lands on the roof and will support the mildew, etc. Generally, though, the materials use din metal roofing themselves will not support this growth. As far as the stone coating performance, again, I go back to the proven history of these products. Individual manufacturers can tell you about their experiences if you wish. Also, I always suggest going to see past jobs in your area to see how they are performing.
