Frequently Asked Questions

For the last 30 years, asphalt shingles have been manufactured using limestone as the base filler for added weight and to cut the expense of manufacturing. Unfortunately, when coupled with moisture, this limestone is a great food resource for algae called “Gloeocapsa Magma.” The bacteria spores are spread by air. Spores land on your roof (typically the north and north east sides which receive less sunlight), begin to feed on the limestone filler in your shingles, and then turn black as the spores form an outer coating to protect themselves against the sun’s UV rays.

As the bacteria colony grows, it lengthens and streaks down the roof. This streaking is caused by gravity and the fact that the colony is holding more moisture on the roof, which also accelerates bacteria growth. The longer the black streaks remain and grow, the more damage is done to your shingles. If the black streaks are left long enough, moss and lichen will begin to grow.

We cannot stress enough the importance of cleaning and treating your roof early to stop the viscous cycle of roof destruction and inhibit the spread throughout your neighborhood. Increase your curb appeal by removing those ugly black streaks.

Yes! If a roof is infested with these contaminants and left untreated it may lose up to 50% of the expected roof shingle life cycle. The black streaks are actually eating the limestone filler in the shingles and causing premature erosion. Roof bacteria, moss, lichen and algae all cause granular loss from shingles. Not only does this erosion weaken the shingles, but the root systems of the moss and lichen can cause small cracks in shingles. The resulting damage will certainly have adverse effects on the life cycle of your roof. Granular loss also reduces reflection of the sun’s UV rays and leaves your roof exposed to the elements.

Pressure washers use kinetic energy to clean with a range of 1500psi-3000psi and are perfect for many DIY and professional projects. Unfortunately, when relying force oftentimes may result in physical property damage and water being blown into the structure. Softwashing uses 45-55psi to apply cleaning agents to kill and safely rinse contaminants away, leaving material intact.

Yes. Our process has been used for over 20 years and proprietary solutions are guaranteed to successfully remove the ugly black streaks from your roof the day of cleaning and treatment. Our 3 in 1 method cleans the roof of black streaks, provides a 100% kill ratio of all bacteria, algae, moss, and lichen to include roots, and inhibits the return of all growth.

Our roof cleaning and treatment process can typically be completed without walking on your roof. Our equipment is designed to reach 4 stories from ground level.

Although there is minimal runoff or over spray to our application, we will take every precaution to protect your plant life and your property. We pre-wet all plants and vegetation as a precaution and we give all plants a final rinsing after the service is complete.

We will NEVER use a pressure washer or high pressure to clean your roof. Our specially designed Softwash roof cleaning equipment applies our cleaning agents at 45 to 50 psi. That’s comparable to the strength of your garden hose or a hard rain fall. We allow our cleaning agents to gently do the work, as recommended by the Asphalt Roofing Manufacturer’s Association (ARMA).

Red River Softwash is a locally owned independent company located in Hooks, TX. We offer professional, full-time exterior cleaning service available to both residential and commercial owners interested in improving the overall appearance of their investment.
