Make Your Roof Look Its Best By Removing Mold Stains

Black streaks and stains found on asphalt shingles are eyesores that make a home unsightly. They also can invite plant matter and fungi to attach to shingles and cause damage if untreated.


These black streaks found on your roof are usually mold or fungi, and they build strength through photosynthesis and a limestone filler found in shingle composition. You can rely on Hometown Roofing of Texas, Inc for mold stain removal throughout the Dallas-Fort Worth area.


Inspections and estimates are free, so call us today to get rid of the mold and algae stains on your home or business.

Get the Facts About Roof Molds and Algae

Today’s shingles are mostly made of limestone and fiberglass, and algae utilize the limestone as a food source. Black algae can only be found on the north- or east-facing sides of a roof. The algae can form a coating that protects it from UV rays.


Areas with little or no light produce algae with a blue-green color. Algae also protect themselves by finding areas of a roof where moisture is most prevalent, as these areas are cool and shady. According to both the American Roof Manufacturers Association and the Canadian Asphalt Shingle Manufacturers Association, algae is only an aesthetic issue and not a damaging issue for your roof.


However, roofs having algae on them attract other life forms that are capable of causing damage. Algae and fungus combinations create something called lichen, which is a photosynthetic fungus with roots that wrap around granules. The plant feeds on shingle filler, and once attached, lichen is hard to remove. Dried-out lichen comes back to life when moisture or rain occurs, and oftentimes, power washing and scrubbing cause even more damage.


Moss is another organism that grows on roofs. It shortens the lifespan of a roof because it retains moisture that freezes in cold weather and causes damage to granules and shingles. Roof cleaning is not a do-it-yourself project. Without proper equipment and training, the result is sometimes disastrous. Professional roof cleaning done by Hometown Roofing of Texas removes streaks and discoloration for much less than roof replacement costs. Call us today for your free estimate.

Jim Otis was exceptional to work with. He presented my wife and me with a game plan and executed it in an extremely timely manner. He went over and beyond what we thought a roofer should do for us. My wife, being in the insurance business, could not believe how well he performed! Thank you, Mr. Jim Otis and Hometown Roofing. I would recommend you to all of my family and friends.
