What Is That Black Stuff Growing On Your Roof?

What are those black streaks on your roof?

The streaks are an algae that feed on the Limestone that’s in your shingles. The algae grows as it eats more limestone on your roof, so you will notice the stains increase with time.

Here is an excerpt from the Washington Post about Roof Cleaning

“Black streaks running down your roof aren’t a sign that the asphalt shingles are dissolving or that you need a new roof. Rather, you have roof algae.

The organisms arrive on the rooftop as either spores or clumps of cells. If they land on the north side of the roof, where the sun is less harsh and moisture more plentiful, the algae will have a good environment to multiply, spreading in a delta down the slope of the roof.

Asphalt shingles contain limestone, which makes them heavy, durable and reflective. Roof algae over time will slowly consume the limestone, ultimately weakening the shingles. Click here to read about Gutter Cleaning Twin Cities.

Algae cells produce a dark pigment that acts as a sunscreen, protecting the cells from the sun. As this pigment accumulates on shingles, the roof becomes less reflective and absorbs more sunlight, which is transferred into the house as heat, raising cooling costs.”

1. What exactly is all the Dark Black Staining on my roof?

This unsightly shingle or tile  roof discoloration is due in part to a pandemic like spread of the airborne spores and later adult cyanobacteria called Gloeocapsa Magma algae. This particularly hardy strain of roof algae cyanobacteria are particularly attracted to limestone which acts like a fertilizer, allowing this once dormant blue green algae to react like a living roof plaque. This is due in part to a reduction in petroleum additives in the asphalt and fiberglass roofing shingle manufacturing process and the increase of “OTHER” inert, crushed and powdered filler material, used to help control the ever spiraling fuel, energy and oil costs.

Due to rising oil prices as a cost saving measure, powdered, limestone and other filler products were added starting 25-30 years ago (about the same time as the OPEC oil embargo) and since that time, the addition of these petroleum “fillers” have been commonplace according to research we have located on the internet.

These inert “additives” have, in recent years, been acting like a “snack food” or corner “Quickie Mart” for many of these roof eating miniature plants, especially Gloeocapsa Magma.

This unknowing addition of what amounts to “Algae Fertilizer” by roofing material into the manufacturing process has since, in part, produced a ever increasing worldwide roof algae pandemeic

Especifically damaging once the algae root system begins to methodically work it way into the sun drenched roofs in the hot, humid densely populated areas, enhancing the degradation of roofing materials located in the southern regions of the U.S.

If you are a property owner and are reading this, chances are, this ALGAE is up on your roof, as well as on shingle or tile roofs all over your neighborhood.

This very fast moving Gloeocapsa Alage , move thru airborne spores, ROOF hopping, if you will, like the common cold, from roof, to shingle or tile  roof, its shortening the longevity of countless roofing, while creating a neighborhood wide eyesore throughout many owns, and cities nationwide.

20 to 25 years ago many roofs typically lasted the full 20 to 30 year lifespan. Not anymore. With Roof life has been shortened in recent years due to increased roof algae, mold, mildew, moss etc.

Many roofs are being replaced today in Tampa due to a lack of proper cleaning and roof maintenance.

Premature shingle or tile  roof replacement can be avoided with proper maintenence.

According to research, staining and  discoloration account for over 60 percent of re-roofing occurring across the country, much of which is unessaary.

Just like washing and maintaining your car, spraying and clearing off your patio, porch or deck of annual debris, or soft washing the vinyl siding on your home, your roof should be cleaned, maintained and treated periodically to repel algae and other ” shingle or tile roof destroyers” .

Naturally, you would not go very long without brushing your teeth, showering or washing your clothes, and along that same line of common sense thinking, it just makes sense that in order for your roof to perform as it should, and to provide you safe shelter for all your belongings and personal possessions, it too should be cleansed and cleared of leaves, pine needles, debris and roof algae, etc.

2. How long does roof cleaning take?

Homes up to 5,000 square feet can usually be completed in one day, depending on the size and scope of the work performed. The average 2,000-3,000 square foot home takes us about 2-3 hours to complete.
