What are the Black Streaks on My Roof?

The black streaks are actually algae buildup. They’re called “black algae” because they appear to be just that: a dark material that covers sections of the roof. It’s not the paint or tar but naturally occurring bacteria that grow in warm, wet areas without air circulation. Algae, like any other plant life, needs light and water to survive. However, when it is exposed to such abundant amounts of both resources it can start growing out of control on your roof and that’s where the problems begin. So what does this mean for you? Well, if you don’t get rid of these pesky microbes soon, they’ll keep growing and eventually cause more damage like leaks and mold growth.

Wondering how to get rid of these black streaks fast? Well, the best thing to do is call a professional external cleaning company who can diagnose potential problems and fix any damage without breaking the bank. Always opt for an experienced roof cleaning company like Dr. Powerwash to stay on the safe side. 

However, the following tips may also be of help to you in preventing black streaks or algae from growing on your roof.

Remove standing water

Standing water can lead to leaks which may cause severe damage to your home as well as an unpleasant odor from the wet materials inside of your house. If you notice standing water on your roof, make sure to drain it off without delay because mold growth will start within 24 hours if left unchecked.

Trim the trees  

Have you ever seen a slimy green substance on your roof?  If so, you’re not alone. It’s algae and it thrives in moist environments. What causes this growth is the trees that are close to your house because they release water into the air which then falls onto the roof of your home where there can be a buildup of moisture from humidity or rainwater. The more humid the environment, the higher risk for algae outbreak on your roof! So if you have trees around your home, make sure to keep them trimmed and try to dry out any areas where water could pool up after heavy storms.
