Have you noticed those dirty stains on your roof? Wondered how they got there, and if you can get rid of them without replacing your roof? Well the answer is here! The algae and moss you see growing on your roof tends to grow on the Northern sides of the roof. This is because it gets less sun and results in longer periods of moisture. The dark colored stains you see are an algae called Gloeocapsa Magma. It is feeding off of limestone, which is used as filler in newer shingles. Paper was used previously, hence why your old shingles didn't get it. Moss also loosens the granules and can cause premature shingle failure, so an ounce of prevention here is worth a pound of cure. If you are considering a new roof, ask us about the algae resistant shingles.

We offer a solution and a prohibitor to this problem. Certainteed, the leading shingle and siding manfacturer, recommends the product we use. For a free estimate, call us at 410-428-6806. Licensed MHIC#89605 - Bonded - Insured
