If you notice black stains on your roof, you may be concerned that there is some damage on your house. While black streaks aren’t a positive and require roof repairs, they won’t cause damage immediately. They can, however, make your roof age prematurely. Here's what you should know about black streaks and what you should do about them. 

Why Does Your Roof Have Black Stains?

1. Algae

Algae often grows on the roof due to moisture and feeds on the limestone in asphalt shingles. It’s important to note that the longer the algae remains on the roof and feeds on the limestone, the weaker your roof becomes. The algae can also trap moisture and eventually cause rot. 

2. Mold and Mildew

Mold and mildew are the most common in humid and rainy times of the year. While it may seem like a good idea to use a pressure washer to clean this off, this can actually make the damage worse. Instead, you should call a professional roofer for roof repairs. 

3. Dirt

The black stains on your roof may simply be dirt. Luckily, a dirty roof is fairly easy for you to clean off by yourself. If possible, you can use a garden hose to wash off the stains, or you might also consult a professional to climb on the roof and use a pressure washer to remove the debris.
