Algae & Moss Prevention and Cleaning for Asphalt Roofing Systems-
What is it: Often mistaken as mold or mildew, the black discoloration and streaks visible on many roofs across the country are actually algae. The algae can form where moisture tends to dwell on the roof surfaces. The most common type (Gloeocapsa magma) protects it self from UV rays by producing the dark black pigment that homeowners see as spots that quickly turn to black streaks, the total roof covering.
What it can do: If left unchecked the growth can cause premature roof aging and damage. When the surface of the roof becomes predominantly black, it is less efficient at reflecting the suns rays and causes the shingles the get much warmer than they would normally. This can speed the deterioration the of shingles alone not to mention the curling of edges of shingles if the growth gets thicker or allows lichen to grow.
What we can do about it: We can make an old roof look NEW, by safely killing the algae and removing the remnants left behind, you will have a new looking, longer lasting and more efficent roof surface. (Also really great for curb appeal when putting a house on the market.)
If you have any quesitons or concerns about the process, please do not hesitate to call and ask! As always, I look forward to speaking with you.
