Why siding and roofs stay green in Chattanooga
Chattanooga has a lot of shade and a lot of water. Homes near the Chickamauga Dam Day Use Area, Williams Island State Archaeological Park and the city’s wooded hills dry out slowly after rain. That damp, shaded surface is where algae, mildew and lichen take hold.
You see it as green film on the north side of the house, black streaks running down the roof, and slick moss on shaded walkways. It does not wash off with a garden hose. The growth has to be killed at the root, or it comes back within months.
With about 181,000 people across Hamilton County’s largest city, there is every kind of surface to deal with. Older brick in one neighborhood, vinyl siding and new concrete in the next. Each one needs a different method.

Services that fit Chattanooga homes
Most calls we get from Chattanooga come down to the same problem: organic growth on shaded surfaces. Here is how we handle it on each part of your property.
For apartment complexes and storefronts, we also offer Commercial Pressure Washing. After a driveway or patio is clean, Paver & Concrete Sealing helps keep water and stains out.
- House Washing: Green film and mildew gone from siding. We soft wash with low pressure and a cleaning solution, so paint, vinyl and stone veneer are not damaged.
- Roof Cleaning: Black streaks and lichen removed from shingles. Roofs never get high pressure. A soft wash kills the growth and rinses away.
- Driveway & Concrete Cleaning: Even, clean concrete with no stripes. We use a rotary surface cleaner and pre-treat oil, rust and organic stains first.
- Deck & Patio Cleaning: Slick, gray boards cleaned without fuzzing the wood. Composite and soft wood get low pressure only.
How a Chattanooga job is scheduled
Our crew drives in from Graysville, TN, about 31 miles from the city. We work 6:00 AM to 8:00 PM, seven days a week, so you can pick a weekday or a weekend. Call Harrison at (423) 387-0784 or email h.murphypowerwash@gmail.com. Sending a few photos of the house, roof or driveway helps us understand the job before we talk price.
You do not need to be home. If there is an outdoor spigot we can use, we can finish while you are at work. Before we spray, we wet your plants and beds, protect them, and rinse them again when we are done. We let you know when the job is finished.
