We are often asked by our customers, if installing Zinc Strips will prevent algae from growing on their roof. Regardless of what the salesman at your local home center may tell you, They Don’t Work!  The proof is in the pictures.  We clean hundreds of roofs throughout Maryland and Delaware every year and see many roofs with the zinc strips installed. These roofs are covered in the same algae and fungas as the roofs without strips. Save your money and have your roof professionally cleaned and maintained by a non pressure roof cleaning company.  Our safe roof cleaning process gently treats your roof, eradicating the algae, mold and fungas. Chesapeake Hydro-Wash guarantees same day results and backs every complete roof cleaning with our exclusive 5 Year Warranty.
