A dry manual standpipe is being routed as a retrofit on the outside of a building. The dry standpipe will have short runs on top of the existing flat roof based on the layout and existing systems within the building.
What is the most prudent way to protect this pipe?
I'm concerned about direct exposure to the sun and rain. At a minimum we will have a couple coats of epoxy paint over primer, but I suspect that even the paint will wear down and required new coats at some point in the future.
