Introduction:
Imagine wearing your favourite clothes, only to find them stained and dirty. It doesn't feel good, right? Now, think about your home. It might be beautiful inside, but how does it look from the outside?
Imagine playing catch with your kids in the backyard on a sunny afternoon. Laughter fills the air as you toss the ball back and forth. Suddenly, your throw goes a bit off course, and the ball lands on the roof.
As you look up to retrieve it, you notice something alarming—ugly, black streaks on roof. It’s frustrating, and you begin to wonder if there’s a serious problem with your roof.
Does this sound like your situation?
If so, you’re not alone. Many homeowners face this issue and ask professional roofing contractors for help. These black streaks are unattractive and annoying. Here’s why they appear and what you can do to fix them.
The Real Culprits Behind Black Roof Stains
Black streaks on roofs are primarily caused by Gloeocapsa magma, a type of algae that thrives on the limestone found in asphalt shingles. This algae prefers warm, humid environments and creates dark stains as it spreads, making your roof look dirty.
Moisture and shade also contribute to algae growth, as parts of the roof that don't get much sunlight stay wet longer after rain or dew, providing perfect conditions for black algae. Additionally, pollutants and airborne debris can settle on the roof, giving algae a place to grow and worsening the stains.
Why Does Algae Grow on Roofs?
Roof algae grows because it feeds on limestone, which is in modern roof shingles. Warm and humid conditions, common in places like Knoxville, help the algae spread. This results in black and brown streaks on your roof.
Should You Remove Algae? Is It Harmful?
It's important to remove roof algae because it can harm shingles and make your roof look dirty. Algae holds water, which leads to moss and algae growth and can cause leaks. This weakens and reduces the lifespan of your roof.
If your roof has cedar shakes or wood siding nearby, algae can cause moss and mildew, which can rot the wood and make your energy bills go up by absorbing more heat.
Removing algae can be tricky. Walking on the roof or using the wrong tools might hurt the shingles. Doing regular roof maintenance prevents future repair.
Cleaning Black Streaks on Roof: Is It Possible?
Now that you know roof algae can cause problems—and it won’t go away if you ignore it—you might wonder, “Can’t I just scrub it off?” Well, you can, but you need to be very careful how you do it.
How To Get Rid Of Roof Algae?
Taking care of your roof is important so it lasts a long time. If you want to remove black algae, don’t use a power washer, which can harm your roof shingles.
Instead, mix half water and half bleach, and gently apply it to the stained parts of your roof. (Wear gloves and avoid breathing in the fumes.) Let the mixture sit for 20 minutes, then scrub with a brush. Finally, rinse the area with clean water.
There are a few drawbacks to cleaning off algae. Chlorine bleach’s effects don’t last long and might cause discoloration. Oxygenated bleach needs to sit on your roof for 45 minutes or more before you can rinse it off. Plus, climbing onto your roof can be risky. So get help from a team of professional roofers.
Stop it from growing back by putting copper or zinc strips on the roof and trimming trees nearby to block less sun. This helps your roof stay in good shape and look nice.
