Soft Wash Cleaning
Non-Pressure No Damage
Roof cleaning in Maryville and Knoxville is essential to the longevity of a shingle roof. The black streaks are algae that are feeding on the shingles. Save time and money by preventing algae, lichen, and moss from causing premature failure. A dirty roof that’s not leaking may not need to be replaced. Let professionals with years of experience bring it back to life. ProClean can restore the original color, regardless of shingle type, with a soft roof wash. Why waste thousands of dollars on a new roof?
Our Roof Cleaning Method
We use custom-built soft wash systems that kill algae without the damage of high pressure. Our soft wash systems are built in-house using Comet® pumps that are capable of spraying 60′ at only 100 psi. Our system’s long-range keeps walking on the roof to a minimum during roof cleaning.
Uniformed, safe, insured professionals. Your property and our technician’s safety are always top priorities. ProClean protects all vegetation and, when possible, bags runoff.
Does Your Roof Really Need Replacing, Or Just Cleaning? (What Most Roofing Companies Won’t Tell You)
If your roof is covered in ugly black streaks or green moss, your first instinct might be to call local roofing companies for an inspection. But here is a dirty secret in the industry: many roofers will immediately recommend a full roof replacement, even when you still have perfectly good shingles.
Replacing a roof is one of the most expensive home improvements you can make, and it’s how roofing sales reps make their biggest commissions.
The truth is, those black stains aren’t actually dirt—it’s a hardy bacteria called Gloeocapsa Magma that feeds on the limestone in your shingles. It looks terrible and can rot the shingles over time, but that doesn’t mean your roof is dead.
Before you spend thousands of dollars with roofing companies on a replacement you don’t need, consider professional soft wash roof cleaning. We use a gentle, low-pressure chemical treatment that kills the root cause and completely restores your roof’s appearance for a fraction of the cost. If your shingles are physically intact and structurally sound, a professional cleaning can easily add years of life to your current roof.

Soft Roof Cleaning – Maryville
Soft Washing is the only roof-cleaning method approved by the Asphalt Roofing Manufacturers Association for shingle roofs. This method kills algae. Not just remove the algae from your sight. They recommend using sodium hypochlorite (chlorine bleach) at a 50/50 ratio with water. Also, a good industrial-strength surfactant should be added to the mix. Surfactants keep the mix wet longer and hold it on the surface, giving the chlorine time to work.
What’s growing on your roof – Maryville and Knoxville?
There are three types of growth that appear on roofs in E. TN. The black streaks are commonly mistaken for mold or mildew. Actually, it’s an algae called Gloeocapsa magma. This algae is hard to kill. Because it protects itself with a dark-pigmented sheath or coating. The colonies spread by airborne spores. The wind and rain also help pull it down the roof. “Black roof algae” is mostly cosmetic. But it slowly feeds on the limestone granules on shingles.
Moss and lichen are the other two types of algae. Both of these species are aggressive and can cause damage if left to grow. They are usually found on the north side of roofs and under overhanging tree limbs. These types of algae thrive in cool and damp areas. Their growth pushes underneath shingles, making them vulnerable to wind and leaks. This is why they’re so damaging. They also hold moisture and divert water in the wrong direction. After our roof cleaning service is concluded, you will notice the moss and lichen have turned light brown. This means it’s dead and will fall off naturally with a few rains.
What Makes Our Roof Cleaning Service Different?
Our roof washing service is more than just spraying bleach all over the roof. Each roof is different and should be treated as such. Our soft roof-cleaning mixture is prepared at varying strengths based on the severity of the algae problem. We only use high-grade chemicals and biodegradable detergents. Ask plenty of questions before you hire a company to clean a delicate and expensive surface such as your roof.

Things To Ask a Roof Cleaning Company:
Do They Have Proper Insurance Coverage?
An above-ground endorsement must be added to their workers’ comp and general liability policies. Otherwise, they are not covered for roof, gutter, or window cleaning. They may not be covered for house washing depending on the height of your home.
How Do They Protect Plants and Other Surfaces?
The minimum protection practices are covering plants and/or drenching everything with clean water before, during, and after the cleaning. A highly experienced company adds neutralizing and collection to the arsenal.
How Many Technicians Will Be On The Job?
Many pressure washing companies are one-man shows. This is fine for house washing, concrete cleaning, and other jobs that use mild chemicals and are primarily performed from the ground. Roof Cleaning requires high-ladder work and strong chemical solutions. One person can’t be on a 24’+ ladder and spraying plants, watching for people, and collecting downspout runoff at the same time. It’s even more unsafe if the tech needs to walk the roof without someone on the ground to spot and help pull the hose into the right position.
Do You Use High Pressure?
Soft washing is now a well-known and adopted roof cleaning strategy. However, it requires very specialized equipment and chemical knowledge that goes far beyond pressure washing. If you hire the cheapest guy instead of the experienced professional, you run the risk of them blasting at your shingles and causing irreversible damage.
Most pressure washing guys/companies offer roof cleaning. This is the most profitable service we offer. However, the dangers to the technicians and the risk of damage are too high to hire just anyone. Make sure they can protect your family, themselves, your home, and your plants.
