Roof Stains in Tampa Should Be Cleaned Without Scrubbing
In my dealings with potential customers who want their black roof stains removed, I’ll sometimes run into someone who thinks the roof should be scrubbed clean with a hard-bristle brush in conjunction with some sort of cleaner. At first this roof cleaning “method” might seem to make sense, but it’s a definite no-no and I’ll tell you why.

I can pretty much guarantee that if you try to clean your Tampa roof stains with aggressive scrubbing or agitation, you’re going to lose a lot of shingle granules in the process. With enough force these will pop right off of asphalt shingles, which is why I also do not recommend roof cleaning with a power washer. Granules do more than just add the color to your shingles. They are vital to your roof’s health because they reflect sunlight, thus keeping your attic cooler and your AC bills lower. If you think your attic is warm now just climb up into one that is covered by a roof that is missing a lot of granules or is covered in black algae stains – you’ll probably notice the difference in temperature. In general, the quicker your roof loses granules the quicker it will lose its integrity, and the quicker you’ll need to get a new roof. So hopefully you can see how important this so-called “shingle grit” actually is.

The other reason you shouldn’t be scrubbing or pressure washing your roof is that in most cases it’s simply not necessary. I go into this in a lot more detail throughout this site, but the bottom line is that if your contractor is using the correct chemicals then no surface agitation should be required. You simply have a roof cleaning professional spray on the chemical with the help of a non-pressure pump

The only rare instance where a pressure washer might be useful is with very thick, green moss, but if all you have are black algae roof stains then you should have no need for scrubbing or power washing. Make the mistake of cleaning your roof with high-pressure or aggressive agitation and you will probably only shorten its lifespan. Using the right roof cleaning chemicals without pressure washing and you will extend your roof’s life.

Its only 5 Days into March in and Tampa Home Owner Associations (HOA) are already busy at enforcing Deed Restrictions and/or covenant rules. Which rules? Rules most people don’t even know about. Restrictions governing the appearance of your Tampa ROOF SHINGLES.
Most people in Tampa think about deed restrictions governing barking dogs and where the garbage cans are stored, but in Tampa, Florida and other states, the “Home Appearance” clause now insists that your tile or shingle roof be ‘free of stains, algae, black mold, moss, mildew, or other unsightly roof distortions’.

Over the last several days I have spoken to a number of homeowners in a Tampa Florida development who have received letters from their Tampa Homeowners Association telling them to Clean their roofs, or the neighborhood association would have them cleaned and send them the roof cleaning bill!

Why clean your Tampa Roof you ask? Its pretty simple actually, think about crab grass.

When your lawn is covered in crab grass, it looks bad, and property values may reflect the unattractive appearance. When you remove the crab grass from your lawn, and your neighbor doesn’t, well the crab grass ends back up in your lawn too! The whole neighborhood suffers.

Black Roof Stains are pretty much like crab grass, but much worse!

* Black Roof Stains are caused by an airborne algae that will spread from roof to roof (if everyone does not keep a clean roof, then no one will have a clean roof).

* Black streaks on your roof (which is the most visible part of the house) will make the house look bad, and everyone’s home then suffers a decrease in value.

* Roof Algae will lead to premature shingle roofing failure.

* Worst of all, black roof algae, can allow mold to get into a home creating ‘sick home’ syndrome.

The solution to this problem ?
First Clean your Tampa Roof w/o Pressure Cleaning. Second Block the Stains from returning.

Origin of the Roof Stains on your Tampa Roof:
Cyano bacteria has existed on earth for millions of years. Bacteria spores are carried by wind, birds, squirrels, etc. The roof stains are caused by the airborne spores from blue / green algae (Cyano Bacteria). These roof raiders land on your roof shingles and feed on the limestone base of the asphalt shingles. The fungus, mold and mildew grow on the roof algae, as they require organic food (the algae) to survive.

Survival – Prior to 1978, cyano bacteria would starve to death when it landed on your Tampa roof:
After 1978 limestone was added to asphalt shingles, and limestone is a favorite food for algae, properly called cyano bacteria gloeocapsa.
So when the wind and birds spread algae to your Tampa roof, it thrives on your roof by eating it!

Roof Stains On Tampa Roof:
Bacteria Gloeocapsa, an airborne bacteria that is spread from one house to another by wind and animals (birds, squirrels).
Roof algae needs three criteria to grow: Heat, moisture, and nutrients.
Your home’s roof, provides sun, rain, and limestone in the shingles. Everything to support a colony of bacteria.
Once the algae / bacteria are in place, fungus and mold arrive! Mold, Mildew, Lichens feed on the roof algae.
The fungus and mildew, would not survive without the roof algae / bacteria, and the roof algae / bacteria survives, because new asphalt shingles are made from limestone.

Roof Stains: Rapid Spread in Tampa
As the roof algae grows, it holds moisture allowing the growth to accelerate.
Thus the roof streaks and stains spread wider and darker over time.
The spread of roof algae, mold, mildew and associated roof fungus extends throughout the country.
Originally believed to be primarily a Florida issue, the spores have been found to survive in some of the harshest climates.
Even shingle manufacturers have indicated that 80 percent of the asphalt shingle roofs in the United States are streaked or showing signs of being affected.
An estimated 40 percent of shingle roofs in Michigan, have an shingle algae problem.
Extreme temperatures won’t prevent the roof streaks spread, extreme heat or cold make them dormant until more favorable weather returns.

Tampa Roof Stains: What to do?
At the first sign of roof algae/fungus streaks, it makes good sense to clean your Tampa roof! Here’s why: As the roof algae and fungus grow on your Tampa roof, they eat away the base of the shingle and expand and contract with the outside temperature. This growth and movement loosens the granules, creating premature granule loss, dramatically shortening the life of your roof. A 25-year roof may not even last 15 years in Tampa if nothing is done. Failure to remove the roof algae will raise roof temperatures by preventing the reflective capabilities of the granules from doing their job. These temperatures make your air conditioner work a lot harder and increase your Tampa Electric bills sometimes as much as several hundred dollars a year.
