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.
Even though protected, we now recognize some things about protected membrane roofs that, many years ago, we did not.
Most building owners think about their roof only when there’s a problem—usually a leak. By that time, water has already caused damage to valuable merchandise, slowed production, and/or caused a slip-and-fall accident. Once the damage is done, all the building owner can do is call a roofing contractor and get the roof repaired.
