Soft washing is a safe, low-pressure cleaning method used to remove algae, moss, mold, mildew, and dirt from exterior surfaces. Instead of using high pressure that can damage shingles, siding, and other materials, soft washing relies on specialized cleaning solutions that break down organic growth at its source.
This process is especially effective for cleaning roofs. The solution kills algae and bacteria that cause the common black streaks you see on shingles, then the weather naturally rinses the surface over time. Because the contaminants are treated at the root, soft washing typically lasts much longer than traditional pressure washing.
Soft washing can be used on many exterior surfaces including roofs, siding, stucco, gutters, fences, and more. It provides a deep clean while protecting your home’s materials and extending the life of your exterior surfaces.

Soft washing uses low-pressure water and specialized cleaning solutions to remove algae, moss, and bacteria without damaging shingles. High-pressure washing can strip granules and shorten the life of your roof.

Those black streaks on your roof are caused by Gloeocapsa magma algae. Soft washing doesn’t just rinse the surface — it kills the algae and organic growth at the source, preventing it from returning quickly.

Because soft washing eliminates the underlying growth, the results last significantly longer than pressure washing alone.

Your roof is one of the most expensive parts of your home. Regular soft washing helps extend the lifespan of your shingles and prevents premature roof replacement.

Removing black streaks and moss can dramatically improve the appearance of your home, making the roof look newer and cleaner.

Many roofing manufacturers recommend soft washing over pressure washing to maintain the integrity of asphalt shingles.
