Blue-green algae has spread to more than 80% of the United States and southern Wisconsin is in the middle to the major threat zone. Leaving stains as it grows the algae makes perfectly good roofs and the homes they cover look prematurely old.
Algae on your roof is a form of bacteria existing as a series of tiny plants. It grows and prospers in highly moisture conditions. The extremely wet summers of this year and last year are idea for algae growth. The species on the roof is also air-borne, so it migrates from roof to roof with high winds. It grows a dark outer layer to protect it from solar heat and UV rays. It’s the same material causing the black stains on your roof. Algae doesn’t threaten your roof’s performance. It is just ugly.
GAF Shingles Feature Break Through Technology
Traditional approaches to getting rid of roof algae include washing shingles with a diluted bleach formula or specialized chemical solutions. Or, sometimes a power washer is used on the roof – which easily damages shingles. Some vendors have suggested fastening strips of zinc on the roof ridge where the element gradually releases onto the roof and trickles from the top down when it rains.
None of these has proven effective. Bleach washing from the roof damages landscape plants. Power washers strip off protective layers of shingles as well as algae. The zinc in strips runs out quickly and can also damage plants.
There have been shingles sold as “algae-resistant” for decades. They feature granules of copper that should release onto the roof when it is wet. Unfortunately, as these shingles age the granules lose their potency. Releasing less and less copper, the shingles are less algae-resistant. The copper in these old-style shingles is gone by the time the roof is halfway through its service life.
Unlike layered technology, StainGuard Plus™ incorporates specially engineered capsules infused throughout with thousands of copper microsites. Hardworking copper remains within reach, ready for timely activation to take on blue-green algae stains. Once installed these shingles eliminate the risk of ugly algae stains. In addition, these high-tech shingles carry a 25-year limited warranty as part of GAF’s overall protection plan.
