What are the black streaks on my house?
Those ugly black streaks on your roof, patio, pool cage or siding are not air pollution or dirt. They are a cyanobacteria called Gloeocapsa Magma. This kind of algae is fueled by Florida’s hot, humid climate. If left untreated, it will eventually take over your exterior surfaces.
What will happen if I let algae stay on my roof?
Leaving algae on your roof is a lot worse than just having to look at a dirty roof. Algae, moss, and lichen will start to decay your roof by holding moisture. Think about a wet sponge on your wood table. After time the water will cause damage as it seeps into the wood. In your case, water is seeping into your roof. Once the liner on your roof is exposed and decaying, leaks will sprout and you will have no choice but to spend thousands of dollars to replace it.
Do I need to be home during cleaning?
In most cases, you do not need to be home. All that we ask is that your animals are left inside and all of the windows are shut. A detailed invoice will be sent the day before giving us permission to work on your home.
Can roof cleaning save me money?
Yes, algae and fungus grow on your roof and eat the limestone, so it shortens the life of your shingle roof. Insurance companies are cancelling insurance policies if they get too bad. The algae also turns your roof black making it less reflective. It retains heat, and  your energy bill will go up! Last but not least, it improves the curb appeal of your house. By cleaning the exterior of your house before you sell, it will  earn you top dollar on your sale!
What is the best way to clean my patio or concete?
Concrete and pavers are very porous and and soak up dirt and algae. Once dirt and algae have settled into the pores, water alone won’t get it out. That’s what makes cleaning a concrete driveway or cleaning a concrete patio very difficult.

The best way to clean concrete is to kill the algae and remove the dirt with a solution first. Using a professional grade cleaner instead of a power washer wand prevents streaking and gives a clean, uniform result.
