Roof Algae Removal

Algae often thrives on asphalt shingles because one of their key ingredients is limestone. The limestone is composed primarily of calcium carbonate, which is what the algae feeds on. Paired with moisture from rain or humidity the perfect living environment for algae is created.

That is why CS Roofing Company has a solution for roof algae problems. We use CopperCat Algae Terminator to help eliminate moss, eliminate algae and eliminate mold.

Roof Algae Removal

If you own a home or a business, you know that issues can occur with your roof from time to time. One of these issues is roof algae. It’s unsightly and it can damage your rooftop if not managed correctly and quickly.

CS Roofing Company is has a solution to prevent roof algae from growing on your roof’s shingles. We use the CopperCat Algae Terminator product for the following reasons:

  • The double-sided copper strip is 20x stronger than zinc strips
  • The copper oxidizes and eventually blends in with your shingles
  • It uses natural process of water interacting with copper to release ions that prevent the  growth of algae, mold, moss and more.
  • It works with new and existing roofs made of asphalt, cedar, slate, etc.
  • Helps improve the overall look of a roof by removing the black streaks, patchy spots and other discoloration.

Why do I get algae on my roof?

Algae often thrives on asphalt shingles because one of their key ingredients is limestone. The limestone is composed primarily of calcium carbonate, which is what the algae feeds on. Paired with moisture from rain or humidity the perfect living environment for algae is created.

How does CS Roofing Company get rid of the algae?

We use a product called Copper Cat. It’s a copper product we instal that cleans the whole slope of your roof. It’s permanent and a lifelong solution that is durable and won’t warp. It prolongs water contact which maximizes results of released ions. It’s aesthetically pleasing in appearance and over times blends in with the look of your natural roof. Watch the video below to learn more about how it works.

Why do I need this product, when I already have a manufacturer’s warranty against algae staining?

It’s a good question, but here are some reasons you’ll want to know:

  1. Algae resistance provisions of asphalt roof shingle warranties are very limited in coverage and scope.
  2. Shingle manufacturers provide a limited, pro-rated AR, or Algae Resistant Warranty. It does not provide any warranty protection against lichens, moss, mildew, or other vegetation which could cause premature shingle failure.
  3. Shingle manufacturer’s warranties only cover algae that is botanically described as “Blue-Green” algae or Cyanobacteria Gloeocapsa Magma. No other algae types are covered.
  4. Copper Cat picks up where the manufacturer’s warranty leaves off.

I know roof algae looks terrible, but how does it harm my roof?

Algae harms your roof by slowly consuming the limestone in the asphalt shingles, ultimately weakening the shingles.

Algae produces a dark pigment on your roof. As this pigment accumulates on shingles, the roof becomes less reflective and absorbs more sunlight, which is transferred into the house as heat, raising your cooling costs.

Algae is likely only the first step of your problem. It colonizes and leads to fungus and together they form lichens, moss then follows and eventually other vegetation can develop. None of these are covered by your manufacturer’s warranty. At that point it is past time for a new roof.

Why don’t I just pressure-wash the algae off of my roof?

The Asphalt Roofing Manufacturer’s Association and all shingle manufacturers recommend not pressure washing your roof. You may see a manufacturer state, “What NOT to do! Do not power wash.” Why? High pressure washing systems are likely to damage asphalt roofing.

It may dislodge granules, which can then lead to premature shingle failure. It is also only a temporary solution and discoloration will likely occur again.

Will the copper strips keep their shiny appearance?

No, over time the copper oxidizes and eventually blends with 90% of shingle colors for a neat and clean look. The speed of oxidization will vary based on the amount of moisture and air pollution that the copper is exposed to in its environment.
