Black streaks caused by Roof Algae...
a common sight through-out West Michigan.

This is the best video... explaining the "black streak" problem exploding here in Michigan. (click to play)

What's on my roof?

With its food source being the limestone filler in asphalt singles, Roof Algae (Gloeocapsa Magma) has successfully migrated north and is thriving in the humid climate of Michigan.

The build-up of dead algae creates a hardy protective "shell", fostering its rapid growth. Visible as dark streaks running down the roof.

Our cleaning process safely kills, disinfects and removes algae, moss, mold and mildew. Rinsing away years of discoloration and restoring to a like new appearance.


Neighbors appreciate it too

As with many homes, the roof-line makes up a large percentage of the visible part of a home. (visible from the street.) Many have noticed the problem but didn't know what it was, or where to turn.

  • ROOF algae gives a home or neighborhood that "run down" look. It also fools many into thinking they need to spend thousands for a new roof.
  • ROOF algae can infect a whole neighborhood, subdivision or condo community, detracting from the overall efforts to maintain an attractive and appealing environment.

Beyond Aesthetics

BSROOF algae multiplies at a fast rate; the ROOT build-up retains moisture and works to dislodge the tiny granules that protect the shingles. The result is a shortened shingle life and a costly roof replacement.

The dark stains can also contribute to increased cooling costs by raising interior temperatures. This increased "heat cycle" also works to further deteriorate and reduce the life of the shingle.

Routine Maintenance

We caulk and paint our homes to protect and beautify, we landscape to make things look nice... If you have an outbreak of black streaks, moss, or algae, it detracts from your home.... Consider roof cleaning, Routine Maintenance.

Algae, Moss, Lichens and even a sprout!

Those shingles are actually green, not black.

  1. Many roofs are replaced prematurely due to appearance, NOT shingle failure.

  2. Cleaning your roof
    can restore its true
    color and help
    maintain proper
    shingle life.

  3. Sterling Maintenance uses cleaning agents which do not harm the environment.

Considering selling
your home?

  1. Roof cleaning greatly
    improves curb appeal and the overall aesthetics of your property.

  2. A dirty, ugly roof raises "red flags" with potential buyers.

  3. Roof cleaning decreases "resistance to buy."
