What is Roof Cleaning?
Roof cleaning is the process of removing all the unwanted stuff that builds up on your roof over time. We’re talking about dirt, debris, moss, algae, lichen, and those dark streaks that make your roof look older than it is.
With the humid climate that Louisiana has, these organisms grow easily on your shingles and if you don’t clean them, they can damage your roof and make it wear out much faster.
The 3 Types of Roof Cleaning Methods
Not all roofs are cleaned the same way. The method depends on your roof type, the materials, and how bad the buildup is.
Method | Best For | Key Benefits |
Pressure Washing | Concrete tiles, metal roofs | Fast removal of heavy buildup |
Soft Washing | Asphalt shingles, delicate materials | Safe, effective, no damage risk |
Chemical Treatment | Stubborn moss, algae, lichen | Targets specific growth problems |
Pressure Washing
This method uses high-pressure water to blast away grime, algae, and moss. While it works fast and gets results, the problem is that too much pressure can cause damage to the singles and even cause links.
Soft Washing
Soft washing is the safest and most effective way to clean most residential roofs. It uses low-pressure water combined with specially formulated cleaning solutions.
This soft wash roof cleaning approach is perfect for shingle roofs because it removes algae, moss, and stains without stripping away the protective granules. At Cajun Softwash, we’ve been using this method since 2013 because it works, and most importantly protects your roof.

Chemical Cleaning
Sometimes specialized cleaning agents are needed to treat tough problems like moss or algae. These solutions are designed to kill growth at the root.
Professional companies use eco-friendly, biodegradable products that won’t harm your landscaping or contaminate water systems. The key is using the right product for the job and applying it correctly.

Benefits of Roof Cleaning
So why should roof cleaning be on your maintenance checklist? Here are the four biggest reasons homeowners in Baton Rouge trust us with their roofs.
1. Extends Your Roof’s Lifespan
Moss, algae, and lichen aren’t just ugly—they’re destructive. These organisms trap moisture against your shingles, which leads to rot, deterioration, and premature aging.
Regular cleaning removes these threats and can add years to your roof’s life. That’s money saved on early replacement costs.
2. Boosts Curb Appeal and Property Value
First impressions matter. A dirty, streaked roof makes your whole house look run-down, even if everything else is in great shape.
A clean roof instantly improves your home’s appearance. If you’re thinking about selling, this can make a real difference in how buyers see your property—and what they’re willing to pay.
3. Improves Energy Efficiency
Dark algae stains don’t just look bad—they absorb more heat from the sun. This raises your attic temperature, which makes your air conditioner work harder.
A clean roof reflects more sunlight and helps keep your home cooler. That means lower energy bills during those brutal Louisiana summers.
4. Prevents Water Damage
Debris buildup doesn’t just sit on your roof—it blocks gutters and downspouts too. When water can’t drain properly, it pools on your roof.
Standing water is bad news. It can lead to leaks, wood rot, and damage to your home’s interior. Keeping your roof clean ensures water flows where it should—off your house and away from your foundation.
How Often Should You Clean Your Roof?
For most homes in the Baton Rouge area, we recommend roof cleaning every 1 to 2 years. But Louisiana’s climate can speed things up.
If you notice dark streaks, moss, or heavy debris, don’t wait. The longer you let it sit, the more damage it can cause.

DIY vs Professional Roof Cleaning
Some homeowners think about tackling roof cleaning themselves to save money. While we get it, there are some serious things to consider first.
Why DIY Roof Cleaning is Risky?
Safety concerns are the biggest issue. Roofs are slippery, especially when wet, and falls can be deadly. Without proper safety equipment and training, you’re taking a real risk.
Damage potential is another problem. Using the wrong pressure, the wrong chemicals, or the wrong technique can strip shingles, void warranties, and cause expensive damage.
Time and effort matter too. What takes a professional crew a few hours can take you a full weekend—if you even finish the job properly.
