Winston Salem Roofing: Article About Prevent Black Algae Stains
There's no doubt that asphalt shingles are an economical and extremely popular choice for many homeowners; however, humidity can cause algae growth and lead to unsightly black streaks on a roof with this type of shingles. While there can be a number of reasons why a roof begins to develop dark streaks, including decaying shingles, dirt and debris, one of the most common reasons is attributed to algae growth.
Algae is not particularly harmful to a roof, but it does present an aesthetic problem. The dark streaks can detract from the look of a home and can even result in a lower resale value. It is now possible to purchase algae resistant shingles, but unless a homeowner is ready to reroof their home, this solution is likely not going to be of much use; at least at the present time.
For homeowners who are considering new shingles, algae resistant shingles can be a great option, especially in humid areas where algae is a common problem. Winston Salem roofing contractors can install these algae resistant shingles, but they also have effective solutions for homeowners who aren't quite ready for a new roof installation.

Cleaning can help eliminate the dark streaks, but the harsh chemicals can have a corrosive effect on asphalt shingles. Whether a homeowner uses a power washer or commercially prepared cleaning solutions, it is important to keep in mind that these cleaning methods can shorten the life span of the asphalt shingles.
In order to get the best results, homeowners should consider cleaning their roof, and then follow up with a preventative measure to avoid future problems. By eliminating the re-occurrence of the black streaks, homeowners can minimize the damage that cleaning will have on their roof's shingles.
One of the most effective ways to prevent algae or moss growth on a roof is to install a strip of copper just below the ridge. Another solution that is a little less effective, but much more budget-friendly, is to install a strip of zinc coated sheet metal.
Whether you choose a commercially manufactured product or a roll of galvanized steel, it is important that the strips are applied properly to the roof. In most cases, the metal can be screwed or nailed directly on top of the asphalt shingles; however, this is a job best left to an experienced roofer. A professional roofing contractor will be able to provide fast installation for quality results.
