Scotchgard™ Protector Vs. Algae Resistant Shingles — Know the differences

Scotchgard™ Protector Vs. Algae Resistant Shingles — Know the differences

Over time and early in their life cycle, roofs can slowly be transformed by ugly black streaks caused by algae. In humid environments, algae cells quickly multiply and dark streaks spread, hiding a beautifully designed roof color. When searching for solutions, you will find there are algae resistant shingles, and then there are Atlas Roofing shingles manufactured with Scotchgard™ Protector — and it’s important to know the difference.

Algae Resistant Shingles

There are two factors that separate one manufacturer’s algae resistant shingle from another: the amount of copper granules used and how they are distributed across the shingles.

The amount of copper granules used per shingle varies from one manufacturer to another. Some manufacturers add only a three to five percent blend of copper granules. This means only very light coverage on the shingles, which cannot help prevent algae from growing and black streaks from forming in the gaps. Additionally, many manufacturers do not add copper granules to every shingle or to the ridge across the top of the roof. This creates a checkerboard appearance, as those untreated shingles will allow algae to grow. The appearance is anything but stunning.

Atlas Roofing Shingles featuring Scotchgard™ Protector

Unlike other algae resistant shingles, Atlas shingles featuring Scotchgard™ Protector have a minimum 10 percent blend of copper granules distributed across every shingle. Independent third party testing verifies this process — just one of the many requirements that make Atlas shingles worthy of the Scotchgard™ name. Moreover, to ensure a roof remains algae-free from top to bottom, the copper granules are uniformly distributed across accessory shingles, including the hip & ridge shingles. This leaves no gaps in coverage and less of an opportunity for black streaks to grow.

To help find the perfect shingle to complement a home, Atlas Roofing offers three shingle options featuring Scotchgard™ Protector — StormMaster® Slate, StormMaster® Shake and Pinnacle® Pristine. These products are all supported by the Atlas Lifetime Limited Algae Warranty; the industry-leading exclusive warranty against unsightly streaks caused by algae provides the homeowner assurance.

While it may seem all algae resistant products are the same, the difference can be clear in just a matter of years. Don’t settle for any algae resistant shingles; ask for Atlas shingles featuring Scotchgard™ Protector.
