Mullin Bros. provides roof cleaning and protective roof clear coats. Phase one of this service is cleaning your roof. Our system of cleaning will not harm your shingles but will remove all algae and moss from your roof. Only rust stains may remain upon cleaning. Phase two is the application of rejuvenate clear. Rejuvenate clear provides a five-year warranty against future algae growth on the surface of your roof. Try our roof clean and clear and make your roof look new again!
