What Are Those Black Stains On My Shingles?

Posted on January 11, 2018

Roofing in Towson, MD

The climate in Maryland is humid sometimes. Some people like the humidity and others don’t. Regardless of your stand on the climate, there are advantages and disadvantages to living in this area.

One of the disadvantages comes in one of the places that you would least expect it: your roof. If you’ve ever driven around a neighborhood and taken notice of the many different roofs you see, there is one problem that you will come across repeatedly.

It is a problem most common with the shingled roofs. Newer shingled roofs will look very uniform and the variations in the coloring and texture are slight if any. This is normal and a good sign. What is concerning, is when you see a shingled roof with black areas on it; almost like black stains.

What is this black stain and where did it come from? What can be done about it and is there any way to prevent it? Let’s find out.

Algae, Moss, and Mold

That black stain on your shingled roof is likely algae. Algae, moss, and mold or mildew all grow in areas where there is a lot of moisture and little sunlight. You will probably notice them on the parts of your roof that are shaded.  Not only do algae make your roof unsightly but it can also lower the resale value of your home. It is especially important to have algae taken care of if you could possibly sell your home in the future.

Algae are bad, but if you notice greenish-white splotches that look like they have been made with a paintbrush, it’s time to call a professional and soon. This could mean an entire roof replacement. It is lichens and they can dig down under your shingles and damage the roof beneath them.

Lastly, if your problem isn’t algae, but mold or mildew, do not attempt to remove it yourself. Mold, especially black mold, can be very dangerous. It can get into your lungs and cause severe illness. It should not only be removed quickly for the sake of your health but can weaken the entire structure of your home.

Will It Hurt My Roof

If detected early, algae can likely be removed by a licensed roofer in Towson, MD. If left unchecked, though, it can do permanent damage and you could be looking at total roof replacement.

Should I Call A Roofer To Remove It

If your roof is more than ten years old, it is wise to call a roofer to inspect it for plant growth and further damage. If you see any black stains, plant growth, or discolorations on your roof, they need properly inspected. It is not recommended to climb on your roof and check these out yourself. It is also not recommended to try to clean stains yourself.Many cleaners can harm your roof and make your shingles deteriorate.
