Thinking about having your roof cleaned? If you’ve noticed moss build-up, black streaks, or tiles looking tired, it’s time to act — and hiring a professional ensures it’s done safely, properly, and without damage.
At Anthony Russell Exterior Cleaning Services, we specialise in safe, professional roof cleaning across Belfast and surrounding areas, with over 15 years of experience working on all types of domestic and commercial roofs.
Here’s what you can expect when you hire a pro.
1. Detailed Roof Assessment
Every roof is different. Before we begin, we inspect your:
-
Tile or slate type (porous? fragile?)
-
Pitch and access points
-
Moss, algae or lichen levels
-
Existing damage or problem areas
-
Nearby guttering and drainage
This helps us choose the safest, most effective cleaning method.
2. The Right Cleaning Method — Not Just Pressure Washing
There’s no “one size fits all.” A reputable roof cleaning company will never blast your roof with high pressure — especially if it’s tiled, aged, or coated.
We use a combination of:
-
Manual roof scraping (ideal for thick moss)
-
Softwashing (low-pressure chemical application to kill spores)
-
Steam cleaning (where safe and suitable)
-
Biocide treatment (to prevent rapid regrowth)
3. Gutter Clearance Included
As moss is removed, it often ends up in your gutters. A professional service will always include clearing your gutters and downpipes as part of the job — avoiding blockages and overflow.
We also offer optional fascia and soffit cleaning for a complete roofline refresh.
4. Safe Access & Full Insurance
Working at height requires care. We use:
-
Ladders, scaffold towers, or MEWPs (cherry pickers) where needed
-
Fall protection and edge guards
-
Full public liability insurance and safety practices
You should always choose a contractor with the right training, equipment, and cover.
5. Before / After Photos & Honest Results
A reputable roof cleaner will show you before-and-after photos so you can see exactly what’s been done — especially useful if access is limited.
6. Aftercare Advice & Optional Roof Sealing
After cleaning, we apply a professional-grade biocide to kill any remaining moss or lichen spores. This helps delay regrowth and keeps your roof cleaner for longer.
We also offer roof sealing where suitable — a breathable protective coating that helps resist moisture and further moss build-up.
