Moss and Algae Growth What It Means for Your Roof
If you’ve noticed dark streaks, green patches, or moss buildup on your roof, you might think it’s just cosmetic—but it could be a sign of moisture retention and damage. Understanding how moss and algae affect your roof can help you prevent costly repairs.
Why Does Moss Grow on Roofs?
Moss and algae thrive in humid environments, often forming on shaded roofs with trapped moisture. Over time, this can degrade shingles and promote rot.
How to Tell If Moss Is a Problem
Look for these common signs of moss or algae growth:
- Dark streaks: Often a sign of algae growth, which can spread quickly.
- Green patches: Thick moss buildup holds moisture, accelerating shingle damage.
- Slippery surfaces: Excess moisture can create safety hazards on walkable roof areas.
How to Prevent Moss Growth
Regular cleaning, proper ventilation, and zinc or copper strips can help prevent moss buildup and extend your roof’s lifespan.
