Mold & Algae Growth
Black streaks and green patches are common in Myrtle Beach's humid coastal climate. Left untreated, these organisms damage shingles and diminish curb appeal.
Types of Biological Growth on Roofs
Gloeocapsa Magma (Black Algae)
The most common cause of black streaks on roofs. Thrives in humid coastal climates.
Green Algae
Creates a greenish tint, especially in shaded areas. Feeds on limestone in shingles.
Moss
Thick green growth that holds moisture against shingles, accelerating deterioration.
Lichen
A combination of algae and fungus that penetrates deep into shingles.
Mold/Mildew
Dark patches indicating moisture problems and potential health concerns.
Why Myrtle Beach Roofs Are Prone to Growth
High Humidity
Coastal air carries constant moisture that algae and mold thrive on.
Warm Temperatures
Mild winters mean organisms grow year-round, not just in summer.
Shade & Trees
Tree cover blocks sunlight that would naturally inhibit growth.
Airborne Spores
Once one roof in a neighborhood has algae, spores spread to others.

Frequently Asked Questions
Are black streaks on my roof harmful?
Yes. While primarily aesthetic at first, algae feeds on the limestone in shingles, gradually degrading them. It also holds moisture against the roof surface, accelerating aging. In Myrtle Beach's humid climate, untreated algae spreads rapidly.
Can I pressure wash my roof to remove algae?
We strongly advise against pressure washing asphalt shingles. High pressure dislodges protective granules and can force water under shingles. We use low-pressure soft washing with specialized solutions that kill algae without damaging roofing materials.
How do I prevent algae from coming back?
We offer algae-resistant shingle installations and zinc/copper strip treatments that inhibit regrowth. Trimming overhanging trees to increase sunlight and improve airflow also helps. Regular roof cleaning every 2-3 years maintains protection.
