BLACK STREAK REMOVAL

Most homeowners know about those telltale black marks that stain your roof. This discoloration is caused by a species of algae called Gloeocapsa magma, otherwise known as roof algae. The bacteria accumulate over time as it feeds on moisture, and calcium carbonate, (the active ingredient in agricultural lime).[2] This accumulation begins to show the black stains as the cyanobacteria develop their dark and hard UV-protective outer coating. As Gloeocapsa continues to grow, they develop expansive and deep root systems resulting in a “hot roof”. Consequently, your home becomes less energy efficient and roof life is significantly shortened. Left untreated, lichen and moss will grow. At Marshall Cleaning Service we use top of the line technology to completely remove spore growth and stains from your roofing. This prevents algae from spreading into your home, gives your home an instant face-lift, and ensures the longest roof life possible.

KEEP YOUR ROOF LONGER

Regular roof cleaning services have been known to lengthen the life of a roof while improving its efficiency saving you money each month. A roof is a costly investment and something you want to maintain on a regular basis.

IMPROVED CURB APPEAL

We use an approach that removes years of organic growth from your roof so it can complement the rest of your home. Make all of your neighbors jealous with great curb appeal and while protecting and maintaining your roof for years to come.

18 MONTH WARRANTY - GUARANTEED

Marshall Cleaning Service is setting the new standard in environmentally responsible exterior cleaning solutions.

The streaks that are staining your roof are actually a strain of bacteria called Gleocapsa Magma. This bacteria is the primary actor for almost all of the roof staining throughout the US. These algae, molds, mildews, bacteria, lichens, and mosses directly decompose and break down roofing materials. Many of the organisms on a roof are there because of the warm, moist environment a roof creates, especially on the north and west sides of a roof. Once there are multiple colonies on a roof, moisture and gravity cause them to elongate and appear as streaks. Each individual streak is one colony of algae. Eventually, these streaks or colonies grow together creating a super colony.

Marshall Cleaning Service can safely remove these damaging micro-organisms and associated staining.
