Black and green streaks are from Algae growth on your homes roof. Allowing Algae to remain on your roof will cause shingles to deteriorate and eventually rot completely due to moisture retention.
Roof algae is not harmful or dangerous in itself, but after a period of time, the algae can cause the protective UV granules that cover roofing shingles to begin to come off, eventually drying them out. Fungus—which also travels through the air—can combine with algae already present on your roof and form into lichen.
Black streaks are a sign of having Algae present. Algae invites a larger more damaging intruder named Lichen, so this is the first sign of needing to have your roof cleaned.
Some companies that aren’t educated in this may say or think that the granules have fallen off your roof due to age. If you’ve heard this, call us for a free estimate & demo to see if your roof just needs to be cleaned.
Known as black algae or roof mold, Gloeocapsa Magma is usually blamed on dirt accumulation, mold and mildew or defective shingles. It’s actually just a blue-green algae spread by airborne spores. It is easily spread and causes those colorful stains on so many roofs. It needs heat, moisture and nutrients to grow.
Generally, it is a good idea to get your roof cleaned by professionals regularly. This is often enough to where if problems develop, they can be caught early on. If you have a roof that is in good shape or was just recently installed, then you may be able to go a little while before a cleaning. At max, you shouldn’t go any longer than 5-7 years.
There’s no cure for Algae growth on roofs. This is something that occurs naturally, and more so depending on location of your home i.e. around lakes.
We do however install zinc strips. These strips are generally good for approximately 5 years. In that time you should be free of any severe growth. All though, once past the 5 year mark its a matter of time before they stop working again.
Lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship. The combined lichen has properties different from those of its component organisms. Lichens come in many colors, sizes, and forms.
Lichen growth isnt dense like moss, so water retention is less of an issue.
The issue with Lichen is how it attaches to the roof and feeds off the limestone roofing manufactures put into their shingles. When Lichen is present, there is already damage occuring. Having a professional roof cleaning company clean your roof can help prevent any further damage.

Yes we can. However, we don’t pressure wash metal roofs. Rather we use our Low-pressure Soft Wash System and eco-friendly biodegradable detergents to clean your metal roof. Which is a less agressive method like soft washing where our detergents do the work and will save from any potential damage that can occur from pressure washing.
Black streaks appearing on your metal roof is an indicator that you have Algae growth. As it accumalates, it will develop a dark hardened outer coating which results in black stains. This can also appear green and lighten the color of your metal roof in appearance as well.
Dull looking metal roofs can also be a sign of oxidation. This is another process in itself and something we do offer if your roof is in need of what we call a “restoration.”
