Roof Cleaning Horsham – Safe, Moss Removal Without Pressure Washing
If your roof in Horsham has become overrun with moss, algae or lichen, you’re not alone. These common growths not only look unsightly but can damage tiles, block your gutters, and lead to costly damp issues if ignored.
At Skyhawk Exterior Cleaning, we specialise in roof cleaning in Horsham using non-pressure, tile-safe methods that get results without risk.
We never pressure wash roof tiles — instead, we combine manual moss scraping with a professional biocide application that keeps your roof cleaner for longer.

How We Calculate Your Roof Cleaning Quote in Horsham
No two properties in Horsham are the same, so we take a detailed approach when preparing your quote.
From the roof size to the condition of your tiles, everything is considered to ensure an accurate and fair price.
Here’s what we look at:
✅ Roof size (m²) – Measured using tools like Google Earth for accuracy
✅ Complexity of the roof – Including dormers, valleys, or extensions
✅ Height and access – Some roofs require towers or special equipment for safe access
✅ Ground conditions – Slopes, soft ground, or tight spaces can affect setup
✅ Level of moss, algae, or lichen – Heavier growth requires more labour and treatment
✅ Age and tile type – Some tiles are more delicate and need extra care
We often start by measuring your roof remotely using satellite tools, then apply a pitch factor (typically x1.2) to reflect the real surface area. From there, we tailor your quote to your exact property – no guesswork, no overcharging.

At Skyhawk - Exterior Cleaning Services, your safety—and ours—is our top priority. Every roof cleaning job in Horsham is carried out using the safest and most appropriate access method, based on the layout and height of your property.
Here’s how we keep things safe and compliant:
-
Ladder access – Suitable for some lower or simpler roofs

Our Roof Cleaning Process in Horsham
Every roof we clean is different, but we follow a safe, proven method:
Step 1: Fast, Flexible Quoting – No Site Visit Needed for Most Jobs
We typically provide quotes remotely using satellite imagery, a few questions, and any photos you can send.
We also offer video call site surveys if you’d prefer to show us around virtually. For larger or more complex roofs, we’re happy to visit in person if it helps you feel confident before booking.
You’ll get a fixed-price quote with no pressure — just straightforward, honest advice.
Step 2: Manual Moss Removal
We use specialist scraping tools on extendable poles to remove moss without walking directly on your roof unless absolutely necessary.
Step 3: Gutter Clearing
All moss and debris is cleared away, and we check and flush your gutters and downpipes to ensure water can flow freely.
Step 4: Biocide Treatment
Once the moss is cleared, we apply a professional biocide to eliminate lingering spores and help prevent moss returning. The treatment continues to work for months, gradually improving the appearance of your tiles.
Step 5: Optional Extras
We can also clean gutters, fascias, soffits, conservatories, or install bird deterrents and gutter guards as needed.

Had the Chris and Craig from Skyhawk Exterior Cleaning over recently for a full roof moss removal and treatment — and honestly, I couldn't be happier with the results. My roof was completely covered in moss and looked tired and neglected, but now it looks fresh and well-maintained. They didn’t just scrape the moss off — they treated it with a proper HSE-approved biocide to prevent it from coming back. You can tell they take pride in their work and know what they’re doing. They were polite, professional, and left everything spotless afterwards, even clearing the gutters and washing down the fascias. If you're looking for reliable roof cleaning in Crawley or West Sussex, I'd highly recommend Skyhawk. Proper job from start to finish.

Chris and the Skyhawk team worked wonders on my heavily Moss and debris laden roof. It hadn't been treated in a number of years and the end result is excellent. The guys really know their stuff and I was really impressed with the care taken and the little additional tasks they undertook, leaving my property looking in great shape. I wouldn't hesitate to use them again and I cannot recommend them highly enough.

Had a really good experience with SkyHawk. They was very professional throughout and the work we got done was excellent. They provided exterior roof cleaning and bird deterrent work. Since the work that finished a week ago, I have a clean roof and no birds. Very happy customer.
