Are you wondering what the black streaks are on your roof?

Delaware Safe Roof Cleaning Maryland

Pollution, tree sap and jet exhaust are the first things people think of when they see staining on their roof. Many are surprised to find that virtually all roof staining and discoloration is organic matter in various stages of growth and decay. Algae, mold, mildew, lichen, and moss are the main culprits.

The black roof streaks you see are actually algae called Gloeocapsa Magma. This algae spreads itself by unseen microscopic spores, just like a dandelion weed. Its spores are airborne and lie dormant until they land on a hospitable environment with moisture and a food source…and guess what that food source is? Your roof. Shingles made today contain massive amounts of food that algae love to eat – that food being limestone. Yes, it is actually eating your roof. In most cases the algae will take root on the north or west facing roof surface or any area of the roof that is subject to limited sunlight. This lack of sunlight allows the roof surface to remain wet longer, providing a perfect environment for the algae to grow.

This eventually leads to extensive shingle damage and the need for early replacement, costing you thousands. Don’t worry, We have the solution!!!

We provide a NON PRESSURE chemical application that removes the roof damaging algae, safely and effectively. Our cleaning process follows the guidelines set by the Asphalt Roof Manufacturers Association, and is the same method taught by leading Exterior Cleaning Organizations.
