What should you know about the black streaks on your roof and how did they get there?

You could find an article upon article about the next and newest magic chemical someone is trying to market and get rich quick over-promising unremarkable results. Many people would rather skip the chemistry lesson and the biology research on roof algae and other living organisms that are on their roof and hire a true professional. Here’s a quick guide to educate our consumers on roof algae.

Well, it’s Alive! Yes! Those ugly black streaks known as roof algae or the scientific name Gloeocapsa Magma, has gained notoriety in the Northeastern part of the United States.  This particular type of cyanobacteria is responsible for creating black stains and streaks on roofs. The bacteria accumulate over time as it feeds on moisture and calcium carbonate. This accumulation begins to show the black stains as the cyanobacteria develop their dark and hard UV-protective outer coating. These stains take months, or even years, to appear, but once they are present they are here to stay, living and feeding on your roof shingles. So how did they get on my roof you ask? Well, you could thank your neighbor or someone in the area, algae spore are thought to break free and become air born and land on your house. These algae spore set up shop on the North Side of your house, as they begin to feed on your asphalt shingle. Every rainfall or moist weather forecast causes an increase in the growth of the roof algae / Gloeocapsa Magma. This formation of roof algae can be noticed streaking towards your gutter line. As our climate in Clinton, CT and surrounding areas begin to warm our problem with roof algae begins growing as well.

Roof algae: more than just a curb appeal problem.

Roof Algae will eat years off your roof by feeding on the limestone filler in the shingles.  Over time your roof will have premature aging, rotting, and granule loss. Roof shingles are designed to reflect sunlight and keep your house cool in the warmer months. As the roof algae become larger growing in size so does its black UV shield. The larger the black stain the more heat absorption from the sun. The heat from the sun becomes trapped in your roof; thus, warming your attic and raising your electric bill.

Why use a Soft Wash Roof Cleaning and not just  Pressure Wash?

What goes into cleaning a roof properly? Why can’t I Pressure Wash it? First, roof cleaning and pressure washing are two very separate techniques with the very distinct equipment. Pressure washing a roof takes years off the roof life and voids warranties. Pressure washers are designed to clean and break free grime and other stains with the use of force or PSI (pound per square inch). This unregulated pressure is the damaging factor and the wrong way to clean a roof. Connecticut Roof Cleaning uses State-of-art-equipment Soft Wash Cleaning coupled with the correct cleaning agents. In fact, the correct chemical usage is the main facet in cleaning a roof properly. Pressure from the unit in the Soft Wash Cleaning System has very little to do with the end result. A Soft Wash System only delivers about 65 P.S.I, as much as a household garden hose.

Clean Black Stains from Your Shingle Roof

One of the most common complaints about the look of a home is black stains on an asphalt shingle roof. These stains are caused by algae that grown within the surface of shingles after prolonged exposure to moisture. The best way to clean black algae stains from a delicate roofing system is soft washing.

Clinton, CT roof cleaning uses only the Asphalt Roofing Manufacturers Association (ARMA) approved method of cleaning roofs. Our process uses a sprayed chemical solution that has proven to be both effective at removing algae and safe to the surrounding environment.

Our roof cleaning solution is contained and controlled to protect your property at all times during the process. We do not use high-pressure cleaning during any part of the roof cleaning process. All roof stains will be removed by the time we leave the job. Any roof moss left behind will be dead and will fall off after a few heavy rains. If you have moss or lichen and want it removed immediately we can scrape it off, but it is not recommended as it pulls granules off the shingles with the roots. We recommend that moss and lichen be left to break at the root level after it is treated.

We do not rinse the solution off because the solution is still active and continues to work hours after applied. The longer it is left on the roof the more effective it is, as a preventive measure against future growth. Not rinsing saves time and money for the homeowner as well as saves water in the process. Once the solution becomes inactive it is simply salt left behind.

The chemical solution that we use has been found by 3M Corporation and the Asphalt Roofing Manufacturers Association (ARMA) to be the most effective and safest method to combat the growth of Gloeocapsa Magma algae, Moss and Lichen on residential roofing shingles.

Frequently Asked Questions (FAQ)

What are the Black Streak on my Roof?

The most common culprit causing the black streaks on roofs is a black alga called Gloeocapsa magma. That’s right! You have organic matter growing and feeding on your roof! Over the past 30 years, this algae has become more aggressive and has migrated via spores released into the atmosphere to cooler less humid environments. It has become a fairly common sight on asphalt shingle roofs across most of the Country.

This ugly growth usually occurs on the north or west side of the house as well as the tree-shaded areas of the roof. As the algae grow and spread, it holds moisture, which accelerates its growth.

Is this Gloeocapsa magma algae dangerous to my roof?

Yes, algae growth on your roof causes several problems over time. First of all the algae is usually black in color so it absorbs the sun’s rays, heats the roof surface quicker, and leads to higher cooling costs. As if that were not enough reason to have it removed, the algae on your roof are actually eating your shingles! This strain of algae feeds on the limestone used in the manufacturing of today’s roof shingles.

Over time the granules protecting the surface of the shingle begin to loosen and wash off as the limestone is diminished. Algae present on roof shingles promotes other damaging biological growth such as lichens and roof moss which are even more harmful if left to grow and spread. Roof moss and lichens anchor into the shingles and spread even more quickly then algae. Moss and lichens grow up into and under the shingles and along edges causing them to lift and make the roof more prone to wind damage and leaks. This destructive growth acts like a sponge that keeps the roof damp causing even more and faster growth

Premature roof replacement could cost you many thousands of dollars. Removing the stains and growth early is your best option. Don’t wait until the entire north side of your roof is black, it may be too late and some damage to your shingles may have already been done.

How do I get rid of this destructive algae, moss, and lichen?

Professional cleaning with environmentally safe solutions and very low pressure is the best answer. Clinton, CT roof cleaning uses only safe, nonpressure system for cleaning roofs. The chemicals do all the work. We systematically apply the cleaner and then wash away the algae to a clean, new looking roof.
