Without algae resistant shingles, your roof can develop ugly black streaks in short order.

In any Central Ohio residential neighborhood, there’s a chance you’ll see at least one roof stained with black or dark brown streaks caused by algae.

Your roof is such a large part of your home’s curb appeal. The stains that algae leave behind can be a big problem. While algae doesn’t harm your roof structurally, those discolored streaks can lower your home’s value. And just make your property look run down.

Many homeowners mistake these stains for mold, mildew, moss, or even tree sap. They’re often actually caused by tiny bacteria commonly called blue green algae (scientific name: Gloeocapsa magma). The dark stains are not the algae. It’s the hard, dark coating it generates to protect itself from damaging UV rays.

The Benefits of Algae Resistant Shingles

Algae can occur on any roof, but is most common on roofs that get a lot of shade during the day, or that just don’t see a lot of sun. The algae can take hold and begin to grow there, resulting in those tell-tale annoying black streaks.

There are a number of ways you can remove algae stains once it begins to grow. But preventing its growth in the first place is your best defense. This is where you need algae resistant shingles.

The new Timberline® AH algae resistant shingles are the only GAF shingles loaded with both LayerLock™ Technology and StainGuard Plus™ Time-Release algae fighting technology.


With algae resistant shingles, you won’t have to worry about unsightly stains.

The StainGuard Plus™ Algae Protection releases copper capsules over time for long-lasting algae-fighting power.  As a homeowner, you have the peace of mind that this protection comes with a 25-year limited warranty against blue-green algae discoloration.

Additionally, Timberline® AH Shingles are eligible for an industry first: a wind warranty with no maximum wind speed limitation.  These shingles hold up to the strongest of Central Ohio winds.

Keep your roof free from those black streaks caused by algae growing on your roof shingles. You don’t want to be the homeowner whose roof detracts from the look and value of the whole neighborhood!
