ALGAE STREAK REMOVAL
Those Black Streaks Are Alive. We Kill Them.
The dark black streaks on your roof are a living organism called Gloeocapsa Magma algae. It feeds on your shingles. We kill it and keep it gone.
What You Need to Know
WHAT IS THAT BLACK STUFF ON YOUR ROOF?
Those dark streaks are not dirt or soot. They are a type of algae called Gloeocapsa Magma that feeds on the limestone filler in your asphalt shingles. It spreads from roof to roof through the air — which is why you often see it on multiple houses on the same street.
Left alone, the algae spreads across the entire roof and shortens its life. It also holds moisture against your shingles, which accelerates deterioration. And it makes your home look neglected, which hurts your curb appeal and your home's value.
The fix is simple. We use a soft-wash treatment that kills the algae at the root and prevents it from coming back for years.
Signs You Need This
IS THIS THE RIGHT SERVICE FOR YOU?
Dark black or gray streaks running down your roof
This is the classic sign of Gloeocapsa Magma algae. It almost always runs in streaks from the ridge down.
Your neighbors have the same streaks
Algae spreads through the air. If your neighbors have it, you probably do too.
The streaks get worse every year
Algae grows and spreads. What starts as a small streak becomes a full roof coverage problem within a few years.
Your roof looks older than it is
Algae makes roofs look much older and more worn than they actually are.
How It Works
WHAT TO EXPECT
We protect your property
We cover all plants, bushes, and landscaping before we start. We also pre-wet everything to dilute any runoff.
We apply the treatment
We apply our soft-wash algae-killing solution to the entire roof surface. It starts working on contact.
We rinse and inspect
We rinse the roof at low pressure and inspect every area to make sure the treatment is complete.
We apply a preventative treatment
We apply a preventative treatment that slows regrowth and keeps your roof looking clean longer.
QUESTIONS WE HEAR ALL THE TIME
Will the streaks come back?
Eventually, yes — algae is in the air. But our treatment plus the preventative coating keeps most roofs clean for 3 to 5 years.
Is the treatment safe for my family and pets?
Yes. We use biodegradable solutions and we take precautions to protect your landscaping, pets, and gutters.
Can I just use bleach myself?
Bleach will kill algae temporarily but it also damages shingles and kills plants. Our professional-grade solution is safer and more effective.
Does algae actually damage my roof?
Yes. It feeds on the limestone in your shingles, which weakens them over time. It also holds moisture that accelerates deterioration.
How much does it cost?
Most homes pay between $250 and $500 for algae removal treatment. We give you a firm price before we start.
