Stains and discoloration on your roof can be a real eyesore. Learn about the common causes of roof stains and how they can be remedied!
If you live in the North Florida area, then you might have recently noticed the appearance of dark stains or streaks on your roof. While this discoloration resembles streaks, it may not appear noticeable under vents. There are actually a number of causes that could be attributed to this discoloration. In order to determine root cause and determine the appropriate course of treatment, it will be important for you to contact a professional roofing contractor.
However, here is a closer look at some of the common causes of roof discoloration:
Algae or Fungal Growth
Algae or fungal growth is a common cause of black streaks on one’s roof, especially in the warm, humid climate of Florida. Many experts believe that this is due to the increased use of limestone as a form of filler material for asphalt shingles. Limestone is certainly an economical choice when it comes to fashioning shingles; however, it contains a compound called calcium carbonate that is beneficial to algae growth.
While most new roofs are equipped with algae warranties, these warranties are generally good only for around 10 years.
If the stains on your room are limited to a certain area of the roof, then it may be caused by trees positioned near your roof. For example, a tree will often drop organic debris on a room that can cause discoloration, like accumulated leaves or sticks. If the tree is a shade tree, then its shady conditions may have encouraged lichen or moss to grow on your roof. Fortunately, this is a condition that is easily treatable.
Black staining on roofs or gutters may be caused by black mold or sooty mold. Black mold growth can be found on fallen leaves, organic roof debris, aluminum gutters, and even wooden roof shingles. Most modern roof shingles are now treated with substances to be resistant to mold, so this problem is generally limited to older roofs. However, it can still occur on newer roofs as well.
Regardless of its cause, if you notice discoloration on your roof, you should contact a professional roofing contractor immediately. If left untreated, the condition could worsen, and it could compromise the integrity of your roof. You certainly do not want to discover how expensive an entire roof replacement can be!
