Our company, TwinCities roof cleaning, was formed in 2004 after we began noticing dark streaky stains on roofs that seemed to be popping up everywhere. Back then many homeowners had no idea what was causing the ugly roof stains. People were theorizing all sorts of possible causes such as acid rain, jet fuel, and even duck poop! Everyone now knows that the dark stains infesting millions of roofs nation-wide are actually caused by algae growth with roots that wrap around the granules on asphalt and fiberglass shingles. We also observed that homeowners and contractors were attempting to clean the roof stains either by using chlorine bleach and phosphate concoctions or high pressure power washing. It was clear to us that high pressure would damage the integrity of the shingles, that phosphates are harmful to our waterways, and that bleach is a toxic chemical dangerous to the environment and to the people using it. We are a company that values quality, innovation, eco-friendly technology, and above all else, customer satisfaction.
