Black Streaks on your Shingles can be a sign of Trouble

What’s growing on my roof?

Most homeowners do not realize what is actually growing on their roof and the damages it can cause. These fast growing organisms slowly break down your roof creating a more inhabitable environment for higher organisms to move in causing even greater damage.

The streaks that are staining your roof are actually a bacteria called Gleocapsa Magma. This is the main culprit for most of the roof staining throughout the US.

There are a few more culprits that also grow up on roofs making a mess of things. Organisms like mildew and algae are unsightly but not as destructive as some of the more aggressive bacterias and fungus.

Moss and Lichens also abound and are the final bad actors that show up after the party has been started by the fungal growths. Algae, molds, mildews, bacterias, lichens and mosses directly decompose and break down roofing materials drastically reducing service life.

Todays asphalt roofing shingles are made with materials that can be metabolized by the micro organisms. Shingles contain limestone which is a base nutrient allowing the growth to flourish.

The good news is that these stains and micro organisms can be safely removed. Our eco-friendly restoration process removes roof growth and is 100% safe for people, pets and plants.
