Why Is My Roof Getting Discolored? Possible Ways To Prevent It

If you are noticing discoloration on your roof or any type of dark streaks along the roof shingles – it is likely there is something wrong with your roof’s integrity. The main reason for this discoloration is because you are experiencing some kind of algae growth. Algae growths can be caused in extremely humid areas. The gloeocapsa magma, also known as blue-green algae, floats through the air and eventually binds themselves to your roof. Spores can grow and multiply in any roofing material which is not metal. This means your entire roof can be suspected of algae growth except the metal components like chimney flashing, gutters, and other metal based joining spots across your roof.

Will Discoloration Affect Your Roof?

Discoloration in your roof may not have an impact on the function and structure of your roof. However, it can detract from the overall look of your home. The streaks on the roof can lead people to believe that your home is in some form of disrepair, or you have older roofing materials. The perception of older roofing materials can cause your house price to lower leading people to avoid putting offers in on your home, or even missing the chance to bid on your home entirely. Which is why we recommend getting rid of discoloration before you put your house on sale.
