Me again...with another question. Should we re-coat our roof with the rubber coating that is mopped or rolled on? Itís a 2014 Wildwood DBUD. Some people have recommended to just clean it real well. So what do you do for your roof? I know that this coating is only applied every 3-4 years. Is this necessary? My husband re-sealed everything on the roof this summer. Thanks again for your input! Your advice is always helpful!!!
