Roofs look great in the weeks and months following their installation. However, over time, they lose their shine as the elements act to wear down the roof’s material. Combined with the growth of algae, moss, and lichen, you’ll have a worn-out roof with lots of black streaks and discoloration in as little as five years.
In this scenario, you may conclude that you need to replace the roof to restore your property’s curb appeal. In reality, all you need is professional roof washing.
SmartWash is the leading name for roof cleaning in Knoxville, TN. We use our custom blend of roof cleaning solutions to restore your roof’s appeal, and our soft wash system will clean the stains from your roof without damaging it.

Dangers of Ignoring Service
A Look at the Main Causes of Roof Discoloration
Ignoring roof stains can reduce your roof’s lifespan by up to ten years. Some of the leading causes of roof discoloration include those listed below.
Black or brown stains on your roof signify the presence of Gloeocapsa magma. These air-borne algae feed on filled-in composite shingles and thrive in humid environments. Thus, you’ll first notice the growth from the northern parts of your roof.
Rain transports the algae down the roof, creating the black streaks you’ll see. However, the rain never washes away the algae entirely. The algae colony will spread until your entire roof has the characteristic decay-like dark coloration.
Apart from the reduced aesthetic appeal, algae can affect your roof in other ways. Algae activity can make the shingles lose their ability to reflect heat, causing a rise in your home’s heating and cooling costs. Such roofs also deteriorate faster, so you’ll need a replacement sooner than expected.
Moss grows in damp and shaded environments. It absorbs moisture from the environment by establishing roots on the roof. Moss activity leads to roof degradation because the roots lift shingles.
The combination of lifted shingles and moss growth will lead to mold. Eventually, your roof could have holes. Moss-covered roofs are also very slippery when wet. If your roof is under any shade, you should take active steps to prevent moss growth on your roof.
A roof lichen is a symbiotic organism formed from the relationship between fungus and algae. Unlike roof moss and algae, roof lichen is more challenging to remove. It is persistent, adhering tightly to the roof.
Professional roof cleaning is the only way to remove the lichen, including the embedded roots. Here at SmartWash, we have years of experience cleaning lichen from residential properties in the Knoxville, TN, area. After we complete the process, the lichen will not return for a long time.

Benefits of Service
Choose a Qualified Roof Washing Company in Knoxville, TN
Roof cleaning is a service that most people don’t consider throughout a roof’s lifespan. However, in the last few years, more people are aware of the benefits of cleaning their roofs.
Unfortunately, homeowners looking for expert roof cleaning companies have to wade through many inexperienced roof cleaning businesses to find qualified experts.
There is no state licensing requirement for cleaning companies in Tennessee. Therefore, anyone can claim to be a roof cleaning company. This lack of oversight is why you find some contractors that pressure wash roofs. The best way to avoid working with inexperienced companies is to choose companies with years of proven history.
At SmartWash, we are the leading name for roof cleaning in Knoxville, TN. With more than a decade of roof cleaning experience, we are not your average roof cleaning company. We have worked on thousands of properties and have many positive reviews from real people near you.
