Wondering What that
“Stuff” is on Your Roof?

Always on Top in the Business!


Roof stains are not just unsightly, they are damaging:

  • GLOEOCAPSA MAGMA OR GM - (These are the black streaks or stains you see that run down your roof in a straight line discoloring theshingles). Gloeocapsa magma is a species of cyanobacteria. This particular type of cyanabacteria is responsible for creating black stain and streaks on roofs. Rising humidity and temperatures combined with more and more bacteria spores promotes their spread with these conditions. Once the bacteria has become noticeable, the stains will continue to worsen year to year. If left untreated as the growth holds moisture within shingles, it can cause premature aging, rotting, and/or granule loss could start.
  • LICHEN - (Round light green spots) are a photosynthetic fungus which will root around the granules of the shingles, eating the nutrients of the GM and the limestone filler and can eat down to the plywood if not removed
  • MOSS - Feeds on algae and other debris on the roof. Moss and debris that remains on your roof can wrap around your shingles and WILL cause premature deterioration and should be physically removed by washing.
  • INSURANCE COMPANIES can cancel your homeowner's policy if not taken care of (we do have documented proof).

We can remove those stains, lichen, moss, etc. with a bleach free soap (not harmful to humans, pets or gardens) to bring back the life it once had costing only a fraction of a new roof.

REMEMBER…………………………Your roof is the most important part of your home, protecting your family and all of your contents.
