Marshall Cleaning Service guarantees no new growth on your roof for 18 months from time of cleaning or we will come back and clean areas of new growth for FREE. Warranty is applied when you have the entire roof cleaned.
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.
