6 Safe Steps to Clean Moss Off Your Roof – Why DOFF Steam Cleaning is the Gold Standard
Why Moss is More Dangerous Than You Think
Moss on a roof might look harmless, but over time it traps moisture, damages tiles, and shortens your roof’s lifespan. It’s more than just a cosmetic issue—it’s a risk to your property’s structure and value. That’s why removing moss safely and correctly is essential.
But here’s the catch: not all cleaning methods are safe for your roof. High-pressure washing can cause severe damage to delicate tiles, while amateur methods risk both safety and effectiveness.
The 6 Safe Steps to a Moss-Free Roof
At CCWC Services, we follow a proven 6-step process using DOFF steam cleaning—a system approved by English Heritage for sensitive surfaces:
1. Risk Assessment and Site Survey
We begin with a detailed risk assessment and site inspection, considering roof pitch, access needs, tile type, and biological growth level. This ensures that our method is tailored to your specific property.
2. Set Up Safe Access – High Rise? No Problem
Using our high-rise access equipment, including cherry pickers and mobile scaffolding, our trained operatives can work safely at height. Safety is our top priority, and every job is supervised by a competent person.
3. Moss Removal with Soft Tools
We manually remove larger moss clumps using non-damaging tools. This prevents clogging in gutters and downpipes, while preparing the surface for steam cleaning.
4. DOFF Steam Cleaning – Safe for Roof Tiles
Unlike pressure washers, the DOFF system uses superheated water (at 150°C) at low pressure. This kills moss spores and removes residue without harming tiles or mortar. It’s environmentally friendly and requires no harsh chemicals.
5. Clean-Up and Gutter Clearance
We clear all gutters and surrounding areas, leaving your property tidy and preventing future drainage issues.
6. Optional Biocide Treatment
To prevent regrowth, we can apply a specialist biocide treatment after steam cleaning—keeping your roof moss-free for longer.
