What Most Contractors Don’t Want You to Know, The Truth About Roof Cleaning (Algae)
If you are one of many homeowners who are thinking about replacing your roof, or know of someone who is, make sure the roof needs replaced. The resident’s of the home below thought they needed a new roof and were excited to hear it only needed cleaned, saving them thousands of dollars. One of the services we provide is roof cleaning. Though we offer pressure washing, we do not pressure wash roofs, low pressure roof cleaning is the answer.
What Are The Black Streaks On My Roof?
Unsightly black stains or streaks on asphalt shingles are caused by a hardy type of algae called Gloeocapsa Magma. The algae feeds on the crushed limestone that is used in asphalt shingles. Rain spreads the algae down the roof causing the black streaks. These streaks are not only unsightly but cause the shingles to fail prematurely by not allowing the shingles to reflect heat properly. 50% Of Roofs Are Replaced Due To The Way They Look.
This is not because of their functionality. Half of the roofs ever replaced didn’t need replaced, only roof cleaning. Just as mold and mildew can grow on your vinyl siding, wind blown algae can land and grow on your roof. Replacing your roof because of this algae is like replacing your siding instead of having it cleaned; it just doesn’t make sense.
Some roofing contractors don’t know what these black streaks are, saying it’s the asphalt showing through the shingles or that it’s water stains. Some contractors may know it’s algae but tell you that roof cleaning can’t be done without damaging the shingles. In either case, they may tell you that the roof needs replaced. This is not true if your shingles are still in good shape. The algae can be killed and removed properly without damaging the shingles using a low pressure chemical application (recommended by shingle manufacturers for roof cleaning)
Before we spray your roof and bag the downspouts to collect the runoff. We have a ground technician constantly watering your landscape before, during and after we apply the mixture to protect them from the solution.
The mixture biodegrades and evaporates from the roof. It leaves dried crystals and surfactant that acts as a treatment to keep the roof cleaner longer. Our mixture removes discoloration and streaks from your roof and requires no rinsing or pressure. The rain actually does a better job washing the mixture off. Rain is slightly acidic with a PH of 5.6. Our solution has a PH of 10-11 and most metropolitan water supplies have a PH of 8. The rain ” reactivates” the mixture at a lower PH. This provides the roof a secondary cleaning, neutralizing the mixture better and helps disinfect the mold and mildew embedded in the shingles.
Our technicians will take you on a final walk around your home to show you the instant result and answer any questions. If you are not home, we will call to ensure that you are satisfied with our service.
Cleaning your roof is one-tenth of the cost of replacing your roof.
Roof Cleaning Is Recommended By Shingle Manufacturers.( click here for ARMA algae document )
The Asphalt Roofing Manufacturers Association (ARMA) recommends a low pressure roof cleaning chemical application using certain cleaners to restore shingles suffering from roof algae, followed by a low pressure rinse.
We use the cleaners and methods recommended by these companies, for a safe and damage free roof cleaning. If your shingles are still in good shape but have roof algae on them, having your roof cleaned will allow you to get the full life out of your shingles, saving you thousands of dollars. We do not recommend cleaning shingles that are in need of being replaced.
If you are still unsure about the status of your roof, we will be glad to evaluate it for you. We will not clean shingles that need replaced, because cleaning the roof won’t solve the problem if the shingles are aged.
On the other hand, if you call a roofing contractor, you may not get the whole truth and may be persuaded into replacing a roof that only needs roof cleaning.
