Restore your roof’s appearance with our professional roof cleaning service. Call (865) 383-3622 to schedule an appointment.

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.

A painter that did some work on the front of my home got green paint all over the brick when he spray painted my front door and shutters. I called SmartWash... and spoke to Brennon, the owner. He sent out technician Tristian who worked a miracle at removing all of the green paint! I am so grateful to SmartWash and will be using them again in the future since they offer many residential cleaning services!read more

We had a great experience with SmartWash. I called and requested a quote and they had someone come out a couple hours later the same day to look at our roof. I... really appreciated that because another company quoted and didn't even look at our roof first. SmartWash also guaranteed 5 years on our roof and another company said a roof should be washed every 6 months. They washed our entire roof and house and it looks completely brand new. We were especially astonished by the gutters and all the white overhangs we have, so bright, everything looks freshly painted but it's just SUPER CLEAN! Very efficient and helpful. Will definitely use again and recommend to others!read more

I've worked with SmartWash before as they did a dryer vent cleanout for me and they did a good job. I also had them quote the house washing but the house was... not ready for it and I did some work on my own. They just finished washing the house, cleaning my stone work that had clay from the original house construction, and they cleaned my solar panels. It was great having a professional crew out. They had the right products and tools to get the job done faster and better than I could. The house looks great - the trim work, naming my white wood soffits looked bad and now they look great. They also got >95% of the clay off the stone which is much better than what I was getting with cleaner and high pressure washer. My solar panels look great and I expect to get more output from them. They did this all in about a 1/2 day. They showed up on time and they listen to you.read more

I am very late getting this review done, but late is better than not at all. Last summer SmartWash did a washing of the eaves, gutters, and other vinyl... trimmed surfaces at my two-story home. The whole process from getting a quote to scheduling and performing the work went very quickly and as promised by the company. The results were very good in most areas. The higher gutters and eaves were still a bit dirty, but I had not had them cleaned since we bought the house in 2004. They were very dirty. The surfaces closer to the ground, such as roof trim on a screened porch were very clean. The technician was very courteous, careful, and diligent in performing the washing. The price for the work was a bargain. I would highly recommend this company for any project that does not require a high-pressure wash.read more

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.

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.
