5 Ways to Prevent Roof Stains From Moss and Algae

Moss and algae are among the most persistent problems of roof maintenance. Rooftops can become potential breeding grounds for them, especially after a storm passes or when the weather is humid.

Moss and algae can grow and spread very quickly. And when a storm damage restoration company arrives, they will have to deal with a slippery roof. It requires a lot of work. So, expect more maintenance and replacement cost.


Thankfully, there are some ways to prevent moss and algae from invading your property.

1. More Sunlight

You can trim down tree branches to allow sunlight to reach your rooftop. This will make the roof less conducive for the growth of moss and algae.

2. Less Debris

Debris such as leaves, dirt and animal droppings that accumulate on the roof surface allows moss and algae to survive. Do a regular cleaning to eliminate the problem.

3. Keep It Dry

Moisture is what’s causing moss and algae to grow. A vinyl window installation expert can locate the presence of moss on the deep corners of the windowsill and help you deal with it.


The same goes for your roof. So, keep you gutters clean all the time. After rain, snow, or hail, make sure to remove all clogs in the gutter.

4. Zinc and Copper

Add some zinc and copper strips to your roof. You can also buy shingles that are moss and algae resistant such as copper-infused asphalt shingles.

5. Applying Solutions

When moss and algae are already visible, you can clean them off using a bleach solution. This method will prevent them from spreading further to other parts of the roof.
