It is quite common for roofs with asphalt shingles to develop black streaks and stains. However, these stains can be both unsightly and inconvenient. Fortunately, you can clean these stains from your roof and having it look as good as new again.

Black streaks on your roof commonly develop as a result of algae growth, and this occurs in areas that experience humidity regularly. There are algae-resistant asphalt shingles on the market. So, if you live in an area that is likely to experience algae growth, you can ask your roofing contractor to have these installed.

As far as cleaning these black stains from your roof, you can periodically clean your roof with a chemical solution and pressure washer. However, you don’t want to do these too frequently, as over-cleaning your roof can actually lead to damage.

There are a number of products on the market made specifically for removing algae stains from your roof. Purchase one of these products and pour it into a pump sprayer. Spray the chemical solution across your roof, and then let it set for 15 minutes. Once that is done, wash it off with a garden hose.

To prevent future algae stains from appearing, you can place copper or zinc sheet metal on each side of the roof, just below the ridge, using roofing nails.
