H2O-PROS Pressure Washing LLC.

H2O-PROS is a licensed and insured exterior cleaning contractor serving Gainesville, FL, and the surrounding communities. We specialize in a low-pressure roof washing process that is safe for asphalt shingles and other types of roofing materials.If you live in Florida, you've probably noticed the dark streaks on asphalt shingle roofs. Though often attributed to an accumulation of dirt, defective shingles, mold, or mildew; the most common culprit is actually blue - green algae known as Gloeocapsa Magma that is spread by airborne spores.One obvious benefit to having your roof cleaned is that it increases your home's curb appeal and helps maintain its value. You may have the most attractive landscaping, beautiful windows and charming mailbox, but black streaks running down your roof can ruin your home's curb appeal and shorten the life of your roof. In addition to keeping your home looking great, keeping your roof clean will help it last longer. Roofing materials break down faster when not kept clean. Though algae growth is largely a cosmetic issue, the algae actually feeds off limestone in asphalt shingles. Algae or moss that grows thick on a shingled roof can create space between shingles and cause the decking underneath to be exposed to moisture, which can cause rot and leaks.
