What Is Soft Wash Roof Cleaning? Everything You Need to Know

Let’s talk about your roof. Sure, it’s not the flashiest part of your home, but it’s one of the hardest-working. Think about it—it shields you from rain, sun, snow, and everything in between. Over time, though, it takes a beating, collecting grime, algae, moss, and lichen that make it not only look worse for wear but can actually shorten its lifespan.
If you’re tired of those stubborn black streaks or green fuzz creeping across your shingles—or if you just want to help your roof last longer—soft wash roof cleaning might be exactly what you need. This method is effective, gentle, eco-friendly, and so much better for your roof than blasting it with high-pressure water. Let’s dive into why soft washing is worth considering for your home!
So, What Exactly Is Soft Wash Roof Cleaning?
Soft wash roof cleaning is a safe, low-pressure method used to clean delicate surfaces like roof shingles. Unlike traditional pressure washing that relies on powerful jets of water, soft washing uses a gentle spray paired with specially formulated, biodegradable solutions to break down dirt, algae, mold, mildew, and other organic growth.
And here’s the beauty of it—it doesn’t just rinse away these unwanted guests; it kills them at the root, stopping them from coming back anytime soon. (That’s more than you can say for your typical pressure washing job.)
What Kinds of Problems Does Soft Washing Solve?
Soft washing works wonders on:
1. Algae stains (black streaks) caused by Gloeocapsa Magma
2. Moss and lichen that damage shingles
3. Dirt buildup that traps moisture and leads to roof deterioration
How Does It Work?
Here’s how a professional typically performs a soft wash:
Inspection
– to assess the roof’s condition.
Application of Cleaning Solution
– eco-friendly mix with surfactants.
Soak & Settle
– allowing the solution to kill algae and mold at the root.

How to Maintain Your Roof After a Soft Wash
Getting your roof soft washed is a great start—but keeping it clean and healthy over time makes an even bigger difference. Here’s how to protect your investment after a professional soft wash:
1. Schedule Regular Inspections
Inspect your roof every 6–12 months, especially after storm seasons. Early signs of moss, algae, or damage are easier (and cheaper) to handle if caught early.
2. Keep Gutters Clean
Clogged gutters cause water to back up onto the roof, creating the perfect environment for mold and algae. Make sure your gutters are cleared out at least twice a year.
3. Trim Overhanging Trees
Shady, damp areas encourage moss and lichen growth. Trim back tree branches that hang over your roof to let sunlight naturally dry it out.
4. Watch for Drainage Issues
Make sure water runs off the roof properly and doesn’t pool near valleys, chimneys, or flat spots. Standing water accelerates roof deterioration.
5. Book Preventative Soft Washing
Even if you don’t see visible stains yet, a gentle preventative wash every few years keeps algae, moss, and grime from getting a foothold in the first place.
