Black Streaks and Your Roof

What Causes the Streaking?

At first glance, the black streaks on your roof might look a lot like dirt, mold, or mildew. You might even think that this staining is it a sign of old or defective roof shingles. As time goes on and the streaking worsens, you may begin to notice a distinct pattern: the shingles directly below areas of metal flashing appear to be unaffected by the strange phenomenon that is occurring on your roof. So, what gives?

More often than not, the black streaks you see on your roof are actually caused by an airborne algae — Gloeocapsa Magma to be exact. This blue-green algae is carried by the wind from one roof to another and is very common in regions with sustained high humidity levels. As you can imagine, roofs in the beautiful south-central area of Mississippi are very prone to this streaking problem.

Unfortunately, all types of roofing materials, including clay and concrete tiles, asphalt shingles, and wood shakes, are susceptible to developing these troublesome streaks. Although the algae growth doesn’t have any serious effect on the structural integrity of roof shingles, it can detract from your home’s appearance and resale value. Wouldn’t it be wonderful if there was an affordable solution for this unsightly problem? Thankfully there is!

How Can 3M Scotchgard Shingles Help?

As an industry leader in shingle technology, 3M has developed a product that is designed to protect your roof against black streaks. While no product can stop algae growth completely, their Scotchgard Protector shingles go a long way in preventing the condition from taking hold on your roof. How does it work?

The secret lies in the shingles’ granules. Through in-depth research and rigorous testing, it was determined that certain chemical elements that are incredibly effective at inhibiting algae growth. Copper is one of those chemical elements, and it is present in roof flashing. This is why areas below flashing tend to have less algae growth than other parts of the roof.

Scotchgard designed their Protector shingles with copper in the granules. The copper slowly dissolves over time with exposure to high levels of moisture, which essentially forms a layer of protection over your roof. Finally, you can say sayonara to those ugly black streaks on your roof.

Can’t I Just Clean My Roof?

We know you’re probably wondering why you can’t just clean your roof to get rid of the algae. While there are several products on the market which are designed to remove algae stains from roof shingles, they often provide short-term results because the algae will eventually grow back. Additionally, corrosive chemicals and power washing your roof can actually shorten the life of asphalt shingles. The better solution is to prevent the algae growth before it starts, and 3M Scotchgard Protector roof shingles make that possible.
