As time goes by, it’s possible for your roofing system to get stained. Depending on the color of stain, it’s likely that you won’t have to worry much as some are not symptoms of roof damage. However, whether it was caused by roof damage or something else entirely, it’s in your best interest to get rid of any discoloration on the system in order to maintain your curb appeal.
Green or Black Stains
If you notice your roofing system has some green or black stains, then it’s likely that the stain was caused by algae, which appears in streaks or patches of slime on the roof. While it doesn’t pose any threat to the health of your roofing system, it’s still an eyesore to have on your home so it’s best to remove it as soon as possible. Popular cleaning methods involve oxygen bleach or a solution of trisodium phosphate applied by a low-pressure wash. Alternatively, you can also have a roof cleaning service take care of it for you. To prevent future algae growth, consider using small sheets of copper or zinc.
Red or Brown Stains
Red or brown stains are tell tale signs of rust or chimney soot stains, another common roof stain. Similar to algae, it can easily be cleaned with a low pressure wash. To prevent future rust stains, consider having a roofing company treat your roof with oxalic acid.
Tree Stains
Tree stains are patches under trees that are often caused by seeds, berries, leaves and other decaying debris that may fall on your roofing system. Under the shade of trees, it’s also possible for moss to grow. To remove tree stains, simply give your roof a thorough cleaning with a low pressure wash and prevent future tree stains by cutting off any overgrown branches of the trees on your property.
Water Stains
Water stains are often characterized by white or yellow discoloration on your roofing system, which suggests a hard-water buildup from an air conditioner or even an evaporative cooler. Once this occurs, consider fading the damage with a vinegar solution. Avoid harsher home remedies as much as possible as they can become dangerous if you accidentally mishandle it.
