Pressure Washing & Parking Lot Striping in Greater Montgomery
Roof Cleaning
Roof cleaning removes the black streaks, moss and lichen that grow on shingles here. Those dark streaks are mostly algae, often a type called Gloeocapsa magma. We clear them with a soft wash: a cleaning solution applied at low pressure. Your shingles keep their protective granules, and the roof looks cleaner from the street.
From our Prattville base, we clean roofs in Montgomery, Millbrook and Pike Road. Our crew serves homes and commercial buildings across Greater Montgomery. We are a family business that wants every roof done right the first time.

What's Included
Roof cleaning starts with a cleaning solution, most often a diluted sodium hypochlorite mix. We apply it gently and never scrub, since friction loosens shingle granules. The solution kills algae, moss and lichen, and a soft rinse carries it off. Roofs across Greater Montgomery come clean this way without the wear of a pressure washer.

A plain rinse leaves living algae behind, so streaks come back fast. Our solution kills the growth where it sits on the shingle. Soft washing is a main service at On Site Power Cleaning. Cleaning is still temporary, and roofing makers note that algae can return over time.
Black algae streaks usually rinse away during the visit. Thick moss and lichen hold on longer, even after they die. Dead growth keeps drying and loosening, and later rains wash much of it off. Forcing it off with pressure would tear up the shingles underneath.
Rinse water runs off the roof into your gutters and out the downspouts. We pre-wet plants near each downspout and rinse them again once the job is done.
Where We Work
We are based in Prattville and serve commercial and residential properties across Greater Montgomery.
View All Service AreasAlgae streaks show most clearly on light-colored asphalt shingles. Shingle roof cleaning with a soft wash protects the granules that shield asphalt from sun. Metal roofs resist moss better, but they still collect algae, dirt and lichen spots. Tile roofs on homes and commercial buildings also clean well at low pressure. Many homeowners pair roof cleaning with house washing so the walls match the roof.
Lichen and moss loosen shingle granules as they grow, which shortens a roof's life. That is why we kill them with a solution instead of scraping them off. Roofs under heavy tree cover usually need more dwell time than open, sunny roofs. A wet roof is slippery, so we keep walking on it to a minimum. Where panels are already up, solar panel cleaning uses a gentle rinse for the glass.

It flows through your gutters and out the downspouts like rainwater. The rinse dilutes the solution as it runs off. We wet the plants near each downspout before and after to keep them protected.
Moss and lichen anchor tightly to shingles, so they let go slowly even after they die. The dead growth dries out and loosens over the following days and weeks. Rain then washes most of it away without any force on the shingles.
Yes, cleaning first makes sense, since panels make much of the roof hard to reach later. Algae and moss left under the panels can keep growing in the shade they create.
Yes, for many homes, because black streaks make a roof look older than it is. Buyers and inspectors tend to notice moss and lichen. A cleaned roof shows its true condition.
Pro Tips
Most parking lots need restriping every one to three years, depending on traffic and weather. Busy shopping center and retail lots usually sit at the short end of that range. Quiet office and warehouse lots can often go longer between fresh coats of paint. Sun, heavy […]
For most homes, the right answer is both, each on the right surface. Soft washing is the safer choice for siding, roofs and painted wood. Pressure washing is the better tool for concrete driveways, sidewalks and other hard, bare surfaces. The difference between soft washing and […]
Siding turns green in Alabama because algae grows wherever walls stay damp and shaded. Tiny algae spores ride in on the wind and settle on siding, trim and roof edges. Warm temperatures and high humidity give them the steady moisture they need to spread. The green […]
