Roof Pressure Washing and Cleaning

Providing Roof Cleaning Services to Commercial & Residential Customers Throughout the Tampa Bay Area

Have you ever wondered where those awful looking stains on your roof came from and why they are so bad on certain sides? Those stains are actually a living plant form (Gloeocapsa magma). This algae is feeding on the limestone filler used to add weight to asphalt shingles. The reason it is more prominent on the north side and shaded areas of your roof is because these areas get the least amount of sunlight. Lack of sunlight means moisture from morning dew and rain remain on these areas longer, creating the perfect environment for maximum growth.

Should you be concerned about it? Yes, besides being an eye sore this algae has a root system and over time it will shorten the life of your shingles by dislodging the granules that protect and give your shingles color.

We clean roof shingles using a “no pressure” approach. The shingle’s granules are its protection. The worst thing to do is to use pressure to clean them because it will blow the granules off of the shingle, severely shortening the life of the shingle.

Our “soft washing” method uses a combination of cleaners, algaecides and soaps to kill the algae at it’s roots. Our custom solutions are based on the Asphalt Shingle Manufacturer Association’s recommendations.

We do however use pressure on tile roof. Call Panorama Tree Care for your consultation today and see the difference on your roof tomorrow.
