Roof discoloration occurs due to varying reasons. Thankfully, it’s not always a cause for alarm, and it can be treated in order to bring back the beauty of your roofing.
Algae Roof Stains
These often appear in patches or streaks of blue-green or black slime. They aren’t considered as harmful as mold. You can get rid of this type of stain by using oxygen bleach or a solution of trisodium phosphate. Algae stain removal can be tricky, so you might want to consider hiring a professional for your safety.
Rust stains typically appear as a red or brown discoloration on the roof. They are often found around the chimney, in which case they may be caused by a rusting metal, such as the chimney flashing. To clean rust stains, you can treat the affected area with oxalic acid. Make sure to have your roof inspected as well. Find out if roof repair would be necessary or a simple replacement of the rusty metal components would be enough.
If a stain only develops in a specific area of your roof, you might want to check the proximity of the stained area to a tree or chimney. The tree, for instance, may be dropping some organic debris on your roof like seeds, leaves and berries, which could be causing the stains. Moss could also grow in the shade of trees, and this can result in dark stains on your roof.
