Your Roof - It's What's for Dinner - 10 Steps to Algae, Moss, Lichen and Mold Growth on Asphalt Shingle Roofs! What every Homeowner Needs to Know!
The process of roof debris accumulation is a gradual one but a damaging one, nonetheless.
1. First, the roofing shingle manufacturer placed crushed limestone in the shingles used a filler, binder to the fiberglass and asphalt shingle matting which made the modern shingle, a natural snack food "pit stop" for the blue -green cyanobacteria GLOEOCAPSA MAGMA algae.
2. Then, Two, the algae was allowed by the homeowner to start growing and then remain on the roof until it was in "full bloom" and covering most of the Northern facing, roofs exposed areas, then later, as the roof continued not to be maintained and properly cleaned, the algae continued its growth as their was never any treatment or biocide or fungicide agent applied (ever) to stop its rapid growth, and soon it covered the entire roof surface.
3. Once the bed was made, i.e. the algae had propagated, sheathed itself by developing its dark colored husk and turning black to protect itself from the sun's rays, it continued to grow and grow, until it built a thick bed of algae, holding in the accumulation of the overnight moisture, roof condensation and dew, which allowed the next phase to occur.
4. This next phase is when their is all the right ingredients for additional growth of OTHER organisms BESIDES the GM algae, such as , LICHEN, MOSS, etc.
5. Once the bed has been made by the HOMEOWNER, neglecting to safely use non pressure roof cleaning methods, like the methods and teaching, here on the ARCA and RCIA, the algae was given all the opportunity it needed to "INVITE" additional "roof dwelling friends" to the party up on the homeowners rooftop.
6. This final stage is when the most damage can occur, when the algae has a thick bedding made and moisture is allowed to soak up into this algae bedding like a sponge, holding many other nutrients that occur by the gradual decomposition of the combination of the dying, re-propagating and shedding of the protective outside layers of the GM algae or husks, in combination with the crushed limestone roof shingle filler "combined" so that the roof now has all the ingredients to grow this moss and lichen.
7. This moss and lichen and algae are like any other plant. They have a root system. Once the roots are firmly planted and embedded in a homeowner’s roof, the roots actually suck or pull nutrients out of the shingle, AND, the roots also tug and pull on the roof shingle GRANULES, thereby dislodging and removing them from the shingle.
8. Granule loss exposes the shingle roof to the repeated day in and day out of the SUN'S brutal and harsh ray's and without the important Ultraviolet Protection, that the granules are designed to provide, the essential oils in the roofing shingle are leeched out of the shingle, causing the shingle to prematurely dry out and become brittle and soon curl and break.
9. Once the roofing shingle has all of these element occurring, the damage is now irreversible and eventually the roof will leak from this massive microscopic attack on the roof that is depended upon to keep all we hold dear and important to us safe and dry.
10. Luckily, much of this can be avoided by proper, regular annual roof maintenance.
Annually, a homeowner can do his /her part to extend and maximize their roofs longevity and life and save themselves thousands in expensive tear-off and re-roofing. Every homeowner should annually get their roof checked for the presence of roof algae, moss, lichen and mold. If any of these are present, the roof should be scheduled for a non pressure roof cleaning by a ARCA or RCIA Certified Roof Cleaning Professional Contractor. Then, once the offending algae, lichen or moss growth is controlled, the homeowner should get set up for annual anti- algae roof treatments to keep their roof looking and performing its very best.

Today I found some black spots in the roof of my mouth?
There are two small black kind of gray spots in the roof of my mouth I'm 22 years old and don't take any medicine does any one know what is the cause of these spots?
There are several reasons for black spots to develop in the mouth, including use of certain medicines or even cigarettes. Most mouth spots are benign and not serious, but there is one rare exception called oral melanoma that is related to the skin cancer of the same name.
Because of this unlikely possibility, I recommend you see your dentist or a dental specialist such as an oral and maxillofacial pathologist or surgeon for a personal consultation for your peace of mind.

The Black (Roofing Shingle) Plague
Homeowners have been plagued for years by unappealing black streaks on their roofs. Frequently, these black stains on shingles are mistaken for fungus, mildew, dirt or oil. In reality, however, a roof's ‘black plague' is normally caused by a rugged type of algae. Unfortunately, this common problem has become worse over the last 20 years as a result of increasingly humid meteorologic trends. In short, algae thrive in increased humidity. Often appearing first on the North slope of a roof where shade supports its growth, algae will continue to spread sometimes covering the entire roof. Once algae are present in an area‚ airborne spores can be carried from rooftop to rooftop, infesting entire neighborhoods. All roof types‚ including wood shakes, concrete and clay tile, and asphalt shingles are susceptible to algae infestation. While algae may cause damage to the roof and its components, the place it does the most damage is to your wallet.
The most common solution to the problem is expensive roof cleaning. These cleanings can cost anywhere from $400 - $700 per cleaning. Unfortunately, this is only a temporary solution as it will require ongoing treatments to minimize the staining. And while there are many reputable roof cleaning companies out there, improper or frequent cleanings can cause damage to your roof.
Sounds like keeping your roof clean is a futile effort, right? Wrong! As you know now, those black streaks are caused by algae. So, what's the best way to get rid of algae stains on a roof? Simple—prevent them from happening.
The most effective way to avoid algae growth is by installing an algae resistant shingle. While many manufacturers claim that their shingle is ‘algae resistant' it is important to remember that not all algae resistance technology is created equal. While most algae resistant shingles are infused with algae-fighting copper granules, they're not always distributed evenly throughout the face of the shingle. This uneven distribution of the granules allows algae to form on the untreated areas of the shingle. Again, uniform distribution of the copper granules throughout the whole shingle is the key to keeping your roof looking clean.
Currently, Atlas Roofing Corporation offers the maximum algae resistance technology offered in a roofing shingle today through their line of Pristine Architectural Shingles featuring Scotchgard™ Protector from 3M. That's right, the same name you trust to keep your household items clean and protected can also help you protect your roof.
All Atlas roofing shingles including StormMaster® Shake (formerly StormMaster® LM), StormMaster® Slate and Pinnacle® are available with Scotchgard™ Protector—and can help ensure that your roof is never afflicted with ‘the black plague' of algae staining and streaking.
