Asphalt shingles are one of the most popular roofing materials available on the market thanks to their affordable price and exceptional appearance. These shingles are available in multiple colors and look great. But unfortunately, they are vulnerable to black streaks.
If you’ve ever looked up at your roof and noticed dark, unsightly streaks running down your shingles, you’re not alone. Many homeowners face this frustrating issue, and it can make even the most well-maintained homes look aged and neglected.
As a premier roofing company, we understand how much curb appeal matters. Whether you plan to sell your home or just want to keep it looking pristine, the last thing you want is a roof covered in black streaks. Fortunately, there’s a long-term solution that you should consider if you are in search of new options: asphalt shingles with Scotchgard™ Protector (A unique option by the innovation powerhouse, 3M™).
What Are These Black Streaks On My Roof?
As a homeowner with a shingle roof, you might have come across a situation where some of your shingles have taken on a black shade. The black streaks you see on asphalt shingles are caused by airborne algae spores. These spores land on your roof and start feeding on moisture and the limestone filler in traditional shingles. Over time, they spread across your roof, creating those ugly dark streaks.
Yes, these are more of an aesthetic problem, but as they spread out across the roof they can hurt your shingles and also bring along some other problems. Many homeowners attempt to clean these streaks using pressure washing or chemical treatments, but these solutions are only temporary. Pressure washing can damage your shingles, while chemical treatments often need to be reapplied frequently.
If you encounter black streaks on your roof frequently, or if there are other problems with your roof, it might be time for a replacement. This could be the best time to select new shingles with Scotchguard Protector.
What Is 3M Scotchgard Protector for Asphalt Shingles?
3M, is a renowned multinational corporation known for its innovation and reliability. One of their popular brands was Scotchgard. Originally, this was a type of fabric protector that repelled stains, but once the company became a household name they expanded their expertise to roofing.
Scotchgard Protector is a built-in technology designed to prevent algae growth on asphalt shingles. This technology works by using copper granules embedded within the shingles.
Copper is naturally resistant to algae, and when distributed evenly across the shingle surface, it creates a base mineral layer on the shingles where algae simply can’t thrive.
What Sets The Scotchgard Protected Shingles Apart?
The key difference between standard algae-resistant shingles and shingles with Scotchgard Protector is the concentration and uniform distribution of copper granules. Many algae-resistant shingles contain copper, but only in limited amounts. This results in uneven protection, which means algae can still grow in certain areas. Shingles with Scotchgard Protector, on the other hand, contain a higher percentage of copper granules. The copper ions here are evenly dispersed, ensuring long-lasting and consistent protection.
Benefits of Choosing Shingles with Scotchgard Protector
Here are a few reasons why you should install algae-resistant shingles that come with Scotchgard Protector for your new roof replacement project:
Long-Term Algae Resistance
Unlike standard shingles that may resist algae for a few years, shingles with Scotchgard Protector offer long-term, consistent protection. You won’t have to worry about black streaks reappearing after just a few seasons.
Maintain Curb Appeal
A streak-free roof keeps your home looking clean, fresh, and well-maintained. This is particularly important if you’re planning to sell your home, as first impressions matter to potential buyers.
Reduce Maintenance Cost
More durable shingles = less maintenance worry. Since algae-resistant shingles prevent black streaks from forming in the first place, you’ll save money that you would have spent on frequent maintenance like roof cleaning as well as roof repairs.
Protects Your Investment
It is natural that when you invest in a new roof, you want it to last as long as possible
As we covered, algae growth doesn’t just affect appearances; it can retain moisture and shorten the lifespan of your shingles. By preventing algae from growing on your roof, Scotchgard Protector helps your roof last longer and also perform better.

- You receive warranty protection, whereas many roofing manufacturers require certified installation for full warranty coverage.
