What Are Those Black Roof Stains?
Have you always wondered what those black roof stains are and what is causing them to appear on your roof?
Most homeowners assume something has failed and the shingle's granules have fallen off fortunately that is not true.The black stains on your roof is a form off algae called (Gloeocapsa Magma) this roof algae is spread by wind and animals and can't be prevented, it has been a problem in the southern United States and now has traveled into parts of Canada, cold and freezing temperature's will not stop the growth of this type of roof algae in Canada, this roof algae feeds off the limestone filler that is put in the shingle's, so every time it rains the algae runs down the roof and over time it will causes those black streaks you see on your roof.
Can The Black Stains Be Removed?
The answer is YES at Durham Roof Cleaning we can remove those ugly black roof stains at a fraction of the cost of a roof replacement, some homeowners are replacing there roof because of these black roof stains and do not know that it can be removed when there roof still has life left.We use a safe non-pressure roof cleaning method that the Canadian Asphalt Shingle Manufacturer's Association (C.A.S.M.A.) recommends.
Lichen (Grey Moss)
In the picture above the roof was covered in Gloeocapsa Magma and Lichen you see the white streaks this is dead Lichen, after are roof treatment this grey moss will go white and then turn brown this will come off in time with a few good rain falls or it can be rinsed off with a garden hose. ( Extra for rinsing.)
