McKinney Roofing: Article About Removing Algae and Preventing Its Reappearance
Black streaks on the roof are the bane of homeowners everywhere. These streaks are an eyesore, can be time-consuming to clean and seem to constantly reappear.
Black streaks are caused by algae called Gloeocapsa Magma. The algae growth is spread by airborne spores and finds itself at home in dark or damp areas of the roof where it feasts on the limestone found in the shingles. Algae can be difficult to clean if the growth resides in hard to reach areas of the roof. The safest way to clean algae off a roof is by climbing an extension ladder and using a good pump sprayer to coat the trouble zones with a commercial roof cleaner or a mix of water and oxygen bleach. Chlorine bleach, while an effective cleaner, should be avoided as it can cause harm to the lawn if it drips down from the roof. If afraid of heights or if unsure about safety, homeowners should consult with McKinney Roofing experts to get the job done.
Observing all safety precautions when climbing a ladder or getting on the roof itself is vital.

Homeowners should wear slip-resistant shoes or roofing cleats, use a sturdy extension ladder, and wear gloves and goggles to protect against the chemicals used.
Once clean, keeping algae from reappearing prevents future trips to clean the roof and avoids the wear and tear that constant cleaning causes on the asphalt shingles.
If it's time for a new roof, homeowners should consider getting asphalt shingles with copper embedded in them. Copper is a natural biocide and shingles imbued with copper are much less likely to develop any kind of algae growth. If it isn't time to replace the roof, installing thin copper strips near the apex of the roof works wonders against buildup. The strip is simply installed underneath the topmost shingles with the exposed portion bent upward. The exposed portion should be roughly three to four inches high. When rainwater hits the house, the miniscule amount of copper it erodes away pours down the entire face of the roof, killing any algae in its path.
Installing copper strips is not overly complicated, but homeowners may want to bring in professional assistance. Professionals are able to install the strips safely, efficiently, and without damaging any of the shingles.
With a good cleaning and the installation of copper imbued shingles, copper strips or both, the roof of any home will be well protected against unsightly black algae streaks.
