Why Does Your Roof Need Cleaning?
Pollution, trees, granular loss and jet exhaust are the first things people think of when they see staining on their roof. They are often surprised to learn that the problem is almost always a growth such as algae, mold and various other fungi, which feed on minerals being held within the asphalt of their shingles.
So many roofs have been replaced due to their appearance and not their functionality. Roofing contractors will be the first to tell you that those stains won't come off. After all, they are in the business to replace roofs not clean them. While we replace roofs too, it's not always the best choice.
Most people are not aware that their roofs are usually just covered in algae. They also don't know that there are companies out there such as ourselves that specialize in the removal of those ugly black stains.
Beware of pressure washing companies! They will claim to do roofs along with the million other things they clean but don't inform you on just how much pressure those machines will put out. Shingles are no match for the pressures of 1000psi and up. The shingles get get blown off, torn, and 99.999% of time the granules will be removed taking away from the structural integrity of the shingles. Only companies like Roof Rejuvenators specialize in safe and effective no pressure soft wash roof cleaning which will not harm roofs and removes 99% of the stains. Our process and cleaning solutions are approved by the Asphalt Roofing Manufactures Association.
What Is Really Causing Those Black Stains?
The most common culprit causing those ugly black stains is a blue-green algae called Gloeocapsa Magma. Over the past 25 years this strain of algae has become hardier and has migrated to the less humid areas. It is now a common sight on 80% of the homes in the US. The algae usually grows on the north or west side as well as shady areas of the roof. As the algae grows and decomposes, it holds moisture, which accelerates its growth. The reason those stains are so common now is due to the way shingles are manufactured. Long story short, the shingle makers are taking the cheap route and adding limestone or marble dust to the asphalt coating as a filler or extender.
Well guess what? Limestone to algae is like peanuts to an elephant. They have an all you can eat buffet now and that is why everywhere you look there are roofs with black stains and streaks.
Roofs infested with algae can see increased energy usages due to the darker color of the roof which means bigger electricity bills due to cooling in the summer. The life span of the roof can also be shortened due to the fact that as the algae grows it dislodges the granules. The longer you wait to clean your roof the worse the problem gets!

What Do We Do Differently?
Roof Rejuvenators uses a no pressure soft wash cleaning process. The pressure is no more than what comes out of your garden hose. Our advanced detergents allow us to soak your entire roof and let it sit. The detergents will then go to work eating away and killing all the algae that has been growing on your roof for years. Once that process is complete we rinse away what's left leaving your roof looking dramatically different. People are so shocked when they see what was hiding under those ugly black stains. Improvements are so dramatic and occur the same day.
