Receiving Professional Help From A Roofing Company: Causes Of Mold And How To Get Rid Of Them

The black streaks on your roof indicate the presence of Gleocapsa magma, a type of blue-green algae or cyanobacteria. The black streaks normally appear on the lower sections of the roof and will taper off towards the ridge. They are hard not to notice. If you are dealing with a mold problem, you should consider contacting a roofing company immediately for professional assistance. Roofing contractors can offer a professional and thorough inspection to determine the extent of the mold growth, and can also give you a better idea on what the most effective methods of removal may be. This article will look at the cause of mold growth and how you can get rid of them. 

What Are Common Causes of Mold Growth on Roofs?

The cyanobacterium typically first arrives on your roof in the form of airborne particles or spores, and will attach itself randomly to the surface of the roofing shingles. They require two important factors to grow: moisture and proper temperature. The cyanobacteria thrives in humid environments, and will often root itself to the north slope for extra shade and moisture support.

This type of mold thrives in the sun, and will require significant exposure for photosynthesis. Its dark color is attributed to the protective sheath that the mold produces to protect itself from the harmful effects of the sun's ultraviolet rays. 

What Are The Effects of Mold Growth?

Luckily, the mold growth will not affect nor influence the structural integrity of your shingles at all nor compromise their lifespan. It merely affects the outer appearance as it takes away from the stunning, uniform colors of the shingles. While mold growth is not an immediate concern to homeowners, its presence does interfere with the outer aesthetics of your home, which can significantly impact the market value of your home.

How Do You Get Rid of the Mold?

Due to the risk of slip and fall accidents, most homeowners will want to leave the mold removal to roofing professionals. Depending on the extent and severity of the mold growth, different strategies may be recommended to get rid of the mold. Some common strategies that are rather effective will include:

  • replacing all of the shingles. This can be a lot of work, and most homeowners will opt for replacing the lighter shingles that they have with darker alternatives that can easily mask the presence of the mold.
  • install shingles that are laced with copper granules from the start or replace your old shingles with new ones that contain copper granules. Replacing your old shingles with new ones can be rather expensive; however, you will never have to worry about experiencing mold ever again.
  • install copper or zinc metal strips near the ridge line of the roof. 
  • spray a solution containing 50 percent bleach in water onto the entire roof or the affected area. This should kill off the spores and the mold, and prevent the mold from returning.

When you are attempting to get rid of the mold, do not power wash the shingles as this will damage the shingles and cause premature deterioration. If you will be walking on the roof, you will need to have proper fall protection to protect yourself from sustaining injuries in the event of an accident. Don't forget that roofing shingles can be extremely slippery!
