Have you noticed stains on your roof? Stains come in a number of shapes, sizes, and colors, and each type of stain could mean something different. So, here’s what you should know about roof stains and what they mean for your home’s roof:

The most common type of roof stains are black streaks. These typically occur from blue green algae growth; these algae spores are often carried through the wind and like to set up shop on your roof, especially if you have asphalt shingles. In addition, the humidity in North Carolina makes the perfect environment for this algae to grow and spread. If you find these unsightly black streaks on your roof, call a professional roofing company to come out and clean your roof. 

If you notice any red stains on your roof, these are likely rust stains from metal on your roof. The metal that causes these rust stains is oftentimes your roof flashing. Again, this is something that we suggest you have checked out by a roofing company. If you decide to clean any roof stains yourself, be sure to use caution when working on your roof, and whatever you do, don’t use a pressure washer as these can cause damage to your shingles.

If you notice dark brown or black stains that are located in only one area of your roof, especially if this area is under a nearby tree, then your stains are likely coming from yard debris. Keep your nearby trees trimmed so that they don’t hang over your roof.
