Q: We have a relatively flat roof on our house that is covered with foam but that needs to have an elastomeric coating put over the foam every few years. But if I have solar panels installed on the roof, how do I maintain that covering that lies under the panels? How can they spread the coating on the foam?

A:Β Solar companies generally install the panels on a system of brackets so that the panels are elevated above the roof. The panels are also tilted to take advantage of the angle of the sunshine. That means that the elastomeric coating for your foam roof can probably be wet- mopped under the panel structure.
