Why should I have the exterior of my residence or business cleaned?
Not only is it important to maintain a clean property for the aesthetic value and much-desired curb appeal, but also to provide lasting protection against building material degradation. When mold, mildew, algae and other environmental pollutants found here in the Tampa Florida area are allowed to remain on the exterior surfaces of a property, they can contribute to premature paint failure, and can also cause permanent staining on concrete, gutters, and pool decks.

How long can I expect my property to stay clean?
Each and every property here in the Tampa Florida area is its own unique situation, but on average, most surfaces will stay clean for about one to 2 years. Some roof surfaces like shingles can stay clean for up to three years or longer, and less for barrel and flat tile roofs. There are many determining factors and environmental variables. Trees for instance, will create shaded and damp areas, creating an ideal environment for algae and mildew to develop and thrive in. Unusually dry or damp weather conditions can also have a direct effect on the length of time that a surface will stay clean. During periods of drought, all surfaces will stay clean longer, due to the reduction in moisture and humidity.

What causes those Black Stains on my roof?
The black streaks and stains seen on many roofs here in Tampa are caused by an algae, technically known as gloeocapsa magma. Once present in an area, the algae can quickly spread by airborne spores being carried from rooftop to rooftop by the wind, birds and other small critters. All roof types, including asphalt and fiberglass shingle, cement, ceramic and clay tile as well as wood shake or metal are susceptible to algae infestation. Our heat and humidity greatly accelerate the formation and growth of these black roof stains.

Can a roof be cleaned with a pressure washer?
Honestly, yes, roofs can be pressure washed. Is it a good idea? Absolutely not! Highly pressurized water can temporarily remove the visible stains, but the toll it takes on the shingle and tile roofing material can be extremely costly. Not only does it not destroy all the algae spores, but it can remove granules from shingled roofs and cause color-fading on tile roofs. Since pressure washing spreads the still living algae spores all over, it is not unusual to have to have your home and driveway cleaned, after the roof  has been pressure washed!
