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 gutters, and lead to costly damp issues if left untreated.
ā
At Skyhawk Exterior Cleaning, we specialise in professional roof cleaning in Horsham, using safe, tile-friendly methods tailored to your roof type.
We offer two options:
ā
-
Manual Moss Removal & Biocide Treatment – Carefully scraping moss from the tiles with specialist blades on telescopic poles, followed by a biocide application to kill off remaining spores and prevent regrowth.
ā
-
Low-Pressure Washing & Biocide Treatment – Using carbon fibre poles, flat-surface cleaners, and turbo nozzles for more intricate areas, this method delivers instant results while being far safer than traditional jet washing. A biocide treatment is then applied for lasting protection.
ā
We’re fully insured, trained in working at height, and trusted by homeowners and businesses across Horsham and the surrounding villages.

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:
ā
ā
Roof size (m²) – Measured using tools like Google Earth for accuracy
ā
Complexity of the roof – Including dormers, valleys, or extensions
ā
Height and access – Some roofs require towers or special equipment for safe access
ā
Ground conditions – Slopes, soft ground, or tight spaces can affect setup
ā
Level of moss, algae, or lichen – Heavier growth requires more labour and treatment
ā
Age and tile type – Some tiles are more delicate and need extra care
ā
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.
Safety Comes First with Every Roof Clean in Horsham
ā
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.
ā
Here’s how we keep things safe and compliant:
ā
-
Ladder access – Suitable for some lower or simpler roofs
-
Scaffold towers – Our go-to solution for most Brighton properties (included in your quote)
-
Scaffolding or cherry pickers – Recommended for high or awkward roofs, quoted separately if requiredā
ā
We’re fully insured and trained in safe working practices, so you can have complete peace of mind knowing your home is in experienced hands.
Our Roof Cleaning Process in Horsham
Every roof we clean is different, but we follow a safe, proven method:
ā
Step 1: Fast, Flexible Quoting – No Site Visit Needed for Most Jobs
ā
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.
ā
Step 2: Manual Moss Removal or Low Pressure Washing
ā
We can offer two safe and effective options for cleaning your roof:
-
Manual Scraping – Using specialist blades on long telescopic poles, we carefully remove moss, dirt, and debris by hand. This method is recommended for older or more delicate roofs to protect the tiles and underlay.
-
Low-Pressure Washing – Using our carbon fibre poles, roof flat-surface cleaner, and a turbo nozzle for more intricate areas, this method delivers instant results while remaining far safer than walking on the roof with a traditional pressure lance. By cleaning from the ground or scaffold, we minimise the risk of water intrusion under tiles and avoid unnecessary damage.
Both methods are designed to protect your roof while delivering great results — we’ll always recommend the most suitable approach for your property.
Step 3: Gutter Clearing
ā
All moss and debris is cleared away, and we check and flush your gutters and downpipes to ensure water can flow freely.
ā
Step 4: Biocide Treatment
ā
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.
ā
Step 5: Optional Extras
ā
We can also clean gutters, fascias, soffits, conservatories, or install bird deterrents and gutter guards as needed.

Excellent soft wash on an old Edwardian house roof with clay tiles followed by biocide treatment to remove any stubborn lingering patches of moss, with all gutters cleared as well as our aco drains on the driveway. Roof has been transformed. Skyhawk were polite, efficient and tidy. Fully recommend.

Would definitely recommend this Company. Very professional Roofing Company. Right from the outset of meeting Chris where he explained everything to me and on surveying our roof showed me what poor condition our roof was. Once agreeing the very reasonable price the communication from SkyHawk was very professional. Craig and Owen cleaned our roof with attention to detail was immense. They genuinely care about what they are doing carrying out the best job they could in a very professional manner.

Our roof looks brand new! The guys worked in very challenging conditions (rain and wind) to get it all done.
