Watch this Designing Spaces segment explaining how Atlas shingles with Scotchgard protection prevent roof algae and protect curb appeal.
Designing Spaces Explores Atlas Shingles Featuring Scotchgard Protection
In this episode of Designing Spaces, viewers are introduced to an innovative roofing solution designed to protect homes from one of the most common roofing problems in America—unsightly black streaks caused by algae growth.
The Designing Spaces feature highlights how modern roofing technology can stop algae before it stains shingles and damages curb appeal. For homeowners across the United States, especially in humid climates, roof algae can spread quickly and affect entire neighborhoods.
What many people believe is dirt or mold is actually algae that forms a dark coating to shield itself from ultraviolet rays. These streaks not only affect a roof’s appearance but can also lower curb appeal and neighborhood home values.

The Real Cause of Black Streaks on Roofs
Roof algae spreads through airborne spores carried by the wind. Once it begins forming on a roof, it can quickly spread throughout entire neighborhoods. Homes with north-facing roof slopes often see algae growth first due to moisture and shade.
Left untreated, algae staining can make a relatively new roof appear old and poorly maintained.
If you’re researching roof discoloration problems, learn more about how algae-resistant shingles help prevent roof staining.
Manufacturers began developing roofing solutions specifically designed to stop algae before it starts.
How Scotchgard™ Algae Resistant Roofing Technology Works
The Scotchgard™ Algae Resistant Roofing System by 3M uses advanced copper granule technology embedded directly into roofing shingles. These granules are coated with a ceramic layer containing copper oxide.
As moisture interacts with the shingles, small amounts of copper ions are slowly released across the roof surface. Copper naturally prevents algae growth, allowing the roof to maintain its original appearance for years.
Because the protection is built directly into the shingle, there is nothing additional homeowners need to apply or maintain.
Benefits Highlighted on Designing Spaces
The technology highlighted on Designing Spaces delivers several important advantages for homeowners who want long-lasting roof performance and appearance.
- Virtually no long-term maintenance required
- Expanded shingle color choices that stay vibrant
- Improved curb appeal and neighborhood value
- Reduced need for roof cleaning or harsh chemicals
- Longer roof lifespan and fewer replacements
- More environmentally friendly roofing solutions
By preventing algae growth, homeowners can avoid pressure washing, chemical treatments, and frequent roof replacements caused by staining.
Why Atlas Shingles Stand Out
Only a select group of manufacturers are licensed to use the Scotchgard™ Algae Resistant Roofing System. In markets east of the Rocky Mountains, Atlas Roofing is one of the leading manufacturers producing shingles with this technology.
These shingles feature copper-coated granules evenly distributed across the entire shingle surface. This ensures algae protection is consistent across the entire roof system, including hip and ridge shingles.
Because of the strict testing requirements behind the Scotchgard name, homeowners can feel confident they are receiving proven algae protection.
Designing Spaces Highlights Smarter Roofing Solutions
