Roof Washing

Roof Cleaning & Washing

RPS uses a unique no-pressure soft wash process to clean your roof. We apply effective, biodegradable chemicals to safely kill all the mold, mildew, algae and underlying bacteria causing those black streaks.

Algae and other types of build-up often form on the north and west parts of roofs that are shaded or receive less sun and can reduce a roof’s life expectancy. The presence of soot, dirt, or biomass can affect how much sunlight is absorbed by a roof and thus the amount of heat a building absorbs.

Our soft wash system is approved by Asphalt Roofing Manufacturers Association and GAF, so you can be assured it is the safest, cost-effective method of roof cleaning for all of our customers.

Neglecting your roof can lead to creeping damage that may be expensive to repair and could cause loss of personal property from intrusion of water and mold. Doing at least an annual cleaning and inspection will go a long way to prevent long-term issues with your roof. A soft wash cleaning begins with the application of particular surfactants or detergents. These cleansers seep into the pits and pores of a home’s roof, working their way along the undersides of roofing shingles as well as around flashing and other roof materials. Soft wash cleansers are gentle but strong, working to dissolve thick grit, grime, dust, dirt, mud, soot, and other such residues. Soft wash systems use low-pressure rinsing to remove dirt. This pressure is typically just slightly stronger than the force created by a garden hose with a spray nozzle. Low-pressure rinsing won’t loosen or cause damage to old, brittle roofing tiles, and won’t wash away damaged granules along their surfaces.

Here are five things every homeowner should know about residential roof washing:
1. Roof washing is not a DIY job but takes skill and know-how.
2. Roofs are best cleaned with a soft wash system.
3. Moss and algae are not just unsightly but cause severe damage to shingles.
4. Debris does not need to be visible from the ground to be severe enough to damage to your roof.
5. Roof washing is not an overpriced service, but a valuable investment in the condition of your home.
