Northwest Washington home with heavy moss growth on the asphalt roof and organic staining on the siding.

BUILT FOR NORTHWEST CONDITIONS

Moisture and Shade Leave Their Mark

Northwest Washington provides the moisture, tree coverage, and shade that moss, algae, mildew, and other organic growth need to thrive.
 

That buildup can spread across your roof, siding, concrete, fencing, and outdoor living spaces. It can make a well-maintained home look neglected and, on certain surfaces, contribute to premature deterioration.
 

RoofGuard identifies the surface and type of buildup before selecting the appropriate cleaning method. Your roof should not be cleaned the same way as your driveway, and your siding should not be treated like concrete.

Professional Roof Cleaning

Remove Moss Without Damaging Your Shingles

Moss, algae, lichen, and dark staining do more than affect your roof’s appearance. Moss can retain moisture and grow beneath shingle edges, while aggressive cleaning methods can remove protective granules and shorten the roof’s life.

​

RoofGuard uses a controlled soft-wash process designed to treat organic growth without relying on damaging high pressure.

PROFESSIONAL ROOF CLEANING CAN HELP

• Treat moss, algae, lichen, and dark streaks
• Improve the appearance of your home
• Reduce moisture-holding organic buildup
• Protect shingles from aggressive cleaning methods
• Reveal areas that may need repair or protection
• Prepare qualifying roofs for NuRoof treatment

LOW PRESSURE. PROFESSIONAL RESULTS.

Your Roof Is Not a Driveway

​

Asphalt shingles contain protective mineral granules that help shield the roof from sunlight and weather exposure. Aggressive pressure washing can loosen those granules, damage shingle edges, and force water into areas it should not enter.

​

Soft washing relies on specialized cleaning solutions and controlled, low-pressure application. The solution treats the organic growth, reducing the need to force it from the roof with high pressure.

The goal is not to blast the roof clean. The goal is to clean it without creating a new problem.

CLEAN. TREAT. PROTECT.

Clean Your Roof for the Last Time

Roof cleaning removes the moss and algae that are already present. NuRoof goes a step further by protecting qualifying asphalt shingles and helping prevent organic growth from returning.

​

If your roof qualifies, RoofGuard can professionally clean the shingles, evaluate their underlying condition, and apply the appropriate NuRoof treatment. You receive a clean roof today with longer-lasting protection for the years ahead.

​

NuRoof is optional and depends on the condition of your roof. We will explain whether cleaning alone or cleaning followed by NuRoof treatment makes the most sense for your property.

OTHER EXTERIOR
SURFACES

Soft Washing or Pressure Washing?

Both methods have a place in professional exterior cleaning. The key is knowing which one belongs on each surface.

SOFT WASHING

Best suited for surfaces that can be damaged by excessive pressure.

Common applications include:
​
• Asphalt-shingle roofs
• Vinyl and fiber cement siding
• Painted surfaces
• Vinyl fencing
• Gutter exteriors

Soft washing relies on cleaning solutions and controlled low pressure to treat buildup.

CONTROLLED PRESSURE CLEANING

Best suited for harder, more durable surfaces when properly managed.

Common applications include:

​

• Concrete driveways
• Walkways
• Patios
• Certain masonry surfaces

RoofGuard adjusts the equipment, pressure, distance, and cleaning process according to the surface and its condition.

CARE BEYOND THE SURFACE

Your Property Deserves More Than a Good Cleaning
​
Professional exterior cleaning requires attention to the entire work area, not just the surface being washed. Before beginning, we evaluate landscaping, drainage, outdoor furniture, electrical fixtures, pets, gates, and other property considerations.

OUR PREPARATION MAY INCLUDE:
​
• Pre-wetting and rinsing nearby vegetation
• Moving or covering appropriate outdoor items
• Confirming doors and windows are securely closed
• Managing hoses and equipment around the property
• Adjusting the cleaning process near sensitive areas
• Completing a final property inspection after service

​
Please tell us about delicate, newly planted, or unusual landscaping when requesting your estimate so we can plan accordingly.

Honest Expectations

Some Stains Are More Than Surface Buildup

Most organic growth and general exterior buildup respond very well to professional cleaning. However, not every visible mark is removable dirt.

 

Rust, oxidation, oil, mineral deposits, paint failure, permanent discoloration, and deterioration within the material may require specialized treatment or may not be completely removable.

 

RoofGuard evaluates the surface and explains what you can reasonably expect before work begins.
