Protected, Vegetated, and More

Today in the United States, we have mostly exposed membranes, generally of very thin, single-ply materials that are vulnerable to vandalism, hail impact, and foot traffic. We’re now coating them to increase albedo and emissivity, but the coatings are of durability that isn’t yet established. We’ve complicated the roof surface not only with HVAC, cell towers, and the like, but with photocells placed close together, or with vegetated areas with unknown consequences with regard to root growth and blocked drainage.
