Why Do I Have Black Streaks On My Roof?

Are you dealing with unsightly black streaks on your roof? These are unfortunately a common problem for homeowners. Luckily though, there are ways to treat the streaks- and to prevent them from forming again in the future. Read on to learn all about this mysterious roofing problem.

What Causes Black Streaks on a Roof? 

Black streaks on a roof are usually caused by a type of algae called gloeocaspa magma. This type of algae can grow in a variety of places. However, it prefers to grow in hot, humid environments with plenty of limestone or other lime-based products to feed on. Of course, this means that Texas roofs are a perfect place for this algae type to thrive. If left untreated, this algae spreads quickly, causing dark-colored streaks or splotches to develop.

Other Possible Culprits

While algae is the most common cause of a roof’s black streaks, other issues might also be to blame. Moss, mold, mildew, dirt, and debris can all affect the color of your roof. Make sure you know the exact cause of your discoloration before you attempt to treat the issue. Using the wrong methods can make the problem worse.

Treating the Problem

A roofing professional can remove algae with certain chemical cleaners, such as chlorine bleach or sodium hydroxide. It’s important to call a professional for this job, as only specific tools and cleaning techniques can safely remove the algae. After cleaning the roof, this professional can help you create a long-term prevention plan to keep the algae from returning. For instance, copper sheets and/or specialized shingles can be installed to help keep persistent algae from growing and spreading.

Start With an Inspection

If you have black streaks on your roof, then you are probably eager to fix the problem. A roofing inspection is the quickest and easiest way to begin the process. During the inspection, a roofing professional will identify the problem and create an action plan.
