In the Peoria area, roof staining often shows up first on shaded or north-facing slopes. Over time, algae and moss hold moisture on the surface and can contribute to premature wear—especially on asphalt shingles.
Damaged shingles from moss lifting the edges
Roof leaks caused by trapped moisture
Black streaks and stains from algae
Reduced curb appeal and home value
Mold exposure and pest infestations
Roof stains aren’t just cosmetic. Organic growth can hold moisture against the roof surface and spread over time, especially in shaded areas. Moss can grow along shingle edges and trap debris, which may increase the chance of water intrusion and shorten the life of the roof.
A professional soft wash addresses the growth at the source and restores curb appeal without harsh pressure. The sooner you treat roof staining, the easier it is to clean—and the longer your roof can perform the way it should.
Roof cleaning should be gentle. That’s why we use a soft wash process designed for roofing materials—no blasting shingles with high pressure. Our approach treats algae and organic buildup at the source, then rinses it away with low pressure to help protect the integrity and appearance of your roof.
We also take steps to protect your property: our team uses proper fall-safety practices, keeps equipment off delicate surfaces whenever possible, and rinses surrounding landscaping before and after the cleaning. The goal is simple—dramatic results without damage.
• Roof Inspection: We identify your roof material, staining type, pitch, and any problem areas.
• Soft Wash Treatment: We apply a roof-safe cleaning solution to break down algae and moss at the source.
• Low-Pressure Rinse: We gently rinse away loosened growth and debris—no harsh pressure on shingles.
• Final Walkthrough: We confirm results, clean up the area, and answer any questions before we leave.
Our soft wash method is ideal for a variety of roof types, but the specific cleaning approach may vary depending on the material and condition of your roof:
Asphalt shingles
Cedar shakes
Metal roofing
Slate tiles
Flat membrane roofs

Roof cleaning makes one of the biggest visual differences on a home—especially when black streaks or moss are visible from the street. Here’s what our soft wash roof cleaning can help you achieve:
• Remove black streaks caused by algae
• Kill and remove roof moss (common on shaded slopes)
• Restore the original color and uniform look of your shingles
• Instantly boost curb appeal across your entire exterior
Every part of your roof is thoroughly covered during the cleaning process to ensure complete protection and consistent results.
Our cleaning process does not leave any part of the roof surface untreated, ensuring a thorough transformation and long-lasting results.
