Why Do Mold and Algae Grow on Roofs?
Mold and algae prefer damp, warm and shady places. The humid locations provide them with the ideal residence in the form of roofs.
Here’s why they grow:
-
Humidity: Lots of moisture in the air means more wet spots on your roof.
-
Shade: If trees hang over your roof, they block sunlight. That shade helps mold and algae grow.
-
Leaves and Dirt: When debris sits on your roof, it traps water. That’s a big “Welcome” sign for mold.
Not only do these organisms make your roof ugly, they also have the potential of destroying your shingles to end up in your walls and decreasing the value of your home.

Step-by-Step: How to Prevent Roof Mold & Algae in Humid Climates
You don’t need to be a roofer to do this. Just follow these steps.
1. Keep Your Roof Clean
-
Remove leaves, twigs, and dirt often.
-
Clean your roof at least twice a year.
-
Use a leaf blower or soft brush—not hard scrubbing.
Tip: Cleaning helps dry your roof faster after rain.
2. Trim Nearby Trees
-
Cut back tree branches hanging over your roof.
-
Let sunlight reach your shingles.
-
Sunlight helps dry your roof and kills mold.
3. Clean Your Gutters
-
Clogged gutters cause water to sit on your roof.
-
Water buildup is perfect for mold growth.
-
Check your gutters every month, especially in rainy seasons.
4. Use Algae-Resistant Shingles
-
Some shingles have copper or zinc mixed in.
-
These materials stop mold and algae from growing.
-
If you’re replacing your roof, ask for these special shingles.
5. Install Zinc or Copper Strips
-
These go along the top ridge of your roof.
-
When it rains, tiny bits of zinc or copper wash down.
-
That stops mold and algae from growing.
Fun fact: Mold hates metal like copper and zinc!
6. Use a Roof Mold Cleaner
-
Use gentle roof-safe cleaners, not harsh bleach.
-
Spray the cleaner, let it sit, then rinse with water.

Don’t use pressure washers—they can break shingles.
