Soft Wash Roof Cleaning Takes Care Of Shingles in Huntington Beach, Costa Mesa, Newport Beach, and Surrounding Areas

Instead of using traditional pressure washing, which can potentially damage shingles, we soft wash the roofs we work on. Soft washing utilizes a low-pressure application of cleaning solutions to break down and remove dirt, algae, mold, and other contaminants. This approach is particularly crucial for asphalt shingles, as they are more susceptible to damage from high-pressure water.

The detergents used in soft washing not only eliminate unsightly stains but also address the root causes of issues like algae and mold growth. Soft washing is just as thorough and effective as pressure washing but doesn't come with the same risks of damage when cleaning delicate surfaces. Our soft washing cleans, protects, and extends the lifespan of your roof!

Frequently Asked Roof Washing Questions

When dark algae stains collect on your roof, they make your shingles less reflective so that they absorb more of the sun's heat. This makes your HVAC system have to work harder to keep your home cool in the summer, impacting your energy efficiency. Washing your shingles makes them more reflective and reduces the amount of heat your roof absorbs!

Those dark streaks on your roof are likely caused by the growth of algae, specifically Gloeocapsa magma or "black algae". Algae growth on roofs often appears as black or dark green streaks, and it can spread if not addressed. This algae growth can absorb excess heat, retain moisture, promote fungi and lichen growth, and even erode your shingles if left to grow on your roof.

Using soft washing and eco-friendly detergents, our roof washing experts can eliminate algae growth and wash away their unsightly streaks. Our regular roof maintenance will help preserve the appearance and structural integrity of your roof for years to come!

Roofs should typically be cleaned every 1–2 years, depending on local climate and the amount of shade and moisture your roof is exposed to. Visible algae streaks, moss, or debris buildup are clear signs that it's time for a cleaning.

Yes. Soft-wash cleaning uses low-pressure water combined with eco-friendly solutions, making it safe for all common roofing materials like asphalt shingles, tile, and metal. It's designed to clean without causing damage to your roof's surface or structure.

After cleaning, maintain your roof by trimming overhanging branches, cleaning gutters regularly, and checking for signs of algae or moss growth. Scheduling routine inspections and periodic soft-wash treatments can extend your roof’s life and keep it looking great.
