Ugly Black Stains On Roof

roof_projects

Let’s face it…your tired of seeing them. Yes, I am talking about those ugly roof stains. Are the buildings in your complex or home covered with black streaks or stains? If so, then you may be surprised by what the staining you see actually is. It is a form of algae called “Gloeocapsa Magma” which feeds on crushed limestone used in common asphalt shingles. The good news is it can be removed using the right roof cleaners and cleaning technique. Many people don’t realize what causes the stains on your roof. We have heard almost everything…from residue of jet fuel to the shingles rotting from the inside out.

The truth is shingle roofs are manufactured with different degrees of quality. Most roofs applied by builders and roofing contractors are in the low quality range with few, if any, fungus fighting elements like zinc or copper. Higher quality roofs are generally found on expensive custom homes and where the owner has taken a special interest in the quality of the roof.

Contributing Factors: – Black fungus requires three things to grow: heat, moisture, and a nutrient. Nutrients can be found within the shingle themselves while other variables contribute to and hasten fungus growth. The north side of the roof is usually the first to exhibit staining because the moisture remains there longer.

Add to that, the type, grade and manufacturer of the shingle, the age of the roof, the close proximity of trees, pool, or lake, how hot and humid the weather is and if there are leaves accumulating on the roof. Now, you have most of the answer to the question why your roof turns black.

What Can You Do?: – If you do nothing, your 25-year roof will most likely last less than 15 years and your homes will remain an unhealthy eyesore. Roof stains will increase energy costs, can cause health issues and its just plain UGLY. You can clean your roof yourself or hire an unqualified contractor, both are a risky proposition, or you can hire a professional like Long Island Roof & Exterior Cleaning. Roof stains can be easily removed with a NO PRESSURE washing and proper safe cleaning solutions. NEVER let anyone use high pressure to clean your roofs.
