Roof spraying involves applying specialist roof coatings directly to your roof tiles using professional equipment. The result is a cleaner, more even finish that transforms how the whole property looks from the street.
At Northern Powerwash, we provide a roof spraying service across the North East and North Yorkshire. Whether your existing roof tiles have faded, become patchy or are covered in moss and algae, our roof coating service can restore the look of your roof without the disruption of a full roof replacement.




Roof coatings work in three ways. Before application, the roof is cleaned thoroughly to remove moss and algae, lichen and debris so the coating can bond properly to the tile surface. Thorough cleaning at this stage is what separates a coating that lasts from one that does not. Once the roof cleaned and dried fully, the surface is ready for the roof spray.
After the coating has cured, roof coatings create a protective barrier that slows down weathering over the years ahead. Roof coatings applied to a well-prepared surface are far more effective and last significantly longer than those rushed onto dirty or damp tiles.
The roof coating application begins once the roof has been professionally cleaned and left to dry. We apply good quality roof paint using professional spraying equipment that delivers an even, controlled coat across the entire roof structure. That gives a more consistent result than brush or roller methods, with no thin patches or missed sections. A professional roof spray also dries faster and bonds more evenly than hand-applied alternatives.
Where a second coat is needed, we apply it once the first is fully cured. Each coat of roof paint adds to the protection and depth of finish, building up the protective coating that will defend the tiles against the elements. That is how roof coating is applied properly, and it is the only way we do it.

How much does roof spraying cost? Based on our recent projects, roof spraying cost typically falls between £1,000 and £3,000 for a standard domestic roof. Roof coating cost depends on roof size, access requirements, tile condition and the number of coats needed.
How much does roof coating add up to when the job is larger or more complex? The answer varies, but understanding how much does roof coating cost for your specific property is exactly what our free quotes are for. Roof coating cost for homes needing more preparation will sit toward the higher end. Roof size is one of the biggest factors in the final figure.
A new roof can cost anywhere from £5,000 to £20,000 depending on pitch, roofing materials and property size. Roof replacement at that cost is a major spend. A new roof also means days of disruption, skips on the drive and waste from old tiles. Avoiding a full roof replacement when the existing roof is structurally sound is one of the main reasons homeowners choose roof spraying instead.

Concrete roof tiles are one of the most common roofing materials we coat. Concrete roof tiles are porous and allow roof coatings to bond well to the surface, which gives a particularly clean and even result. Concrete tiles that are faded, stained or mossy respond very well to roof tile painting. Concrete tiles are also one of the most affordable tile types to maintain using a spray-applied roof coating.
Clay roof tiles can also be coated in many cases, though clay tiles require a breathable product to avoid trapping moisture beneath the surface. Composite and fibre cement tiles are often suitable for roof coatings too, depending on their age and condition. Silicone roof coatings work well on certain surfaces, including flat roof sections, where flexibility and water resistance are especially important. The right product for a flat roof will differ from the right product for a pitched tile roof, so we always match the coating to the surface.
Metal roofs and some flat roof surfaces may need specialist roof coatings rather than a standard product. Asphalt shingles and wooden shingles behave differently to concrete or clay tiles, so the product must match the roofing materials involved.
Metal roofs can be coated in some cases, but they need a product designed for metal rather than tile. We always assess the existing roof and roof structure before recommending roof coatings, so you are never sold something that is not right for your roof. Recommending the right roof paint for the material is part of how we keep results lasting longer.
Roof coatings act as a protective coating between your tiles and the elements. A high quality roof coating slows down the surface deterioration that leads to cracking and the kind of costly repairs that come from years of untreated exposure to the weather.
When the protective layer breaks down and tiles are left bare to harsh weather conditions, water gets in. In winter that water freezes, expands and damages the tile from inside. Minor repairs are far cheaper when caught early, and applying roof coatings before things deteriorate further will always cost less than leaving it.
How long does roof coating last when properly applied? A high quality roof coating on a clean, well-prepared surface will typically last between 10 and 20 years. How long does roof coating remain effective depends on the prep work done, the product used and how exposed the roof is to the elements.
Roofs in more exposed locations with persistent moss and algae problems may need maintenance sooner. Keeping the roof cleaned every few years and dealing with organic growth early extends the life of roof coatings considerably. We recommend the roof cleaned on a regular schedule rather than waiting until moss and algae become a major problem. A roof cleaned every few years will hold its coating far longer than one left to accumulate organic growth.
A roof professionally cleaned and coated at the right time will always outlast one left untreated.


A newly painted roof changes how the whole property looks from the street. Roof tile painting restores a more even colour across the roof tiles, removing the patchiness that comes from years of mixed weathering. That is where kerb appeal comes in. A clean, consistent roof makes the whole home look better maintained, which is worth a great deal whether you are staying or selling. That visual lift is one of the most immediate results of a professional roof spray. It is also one of the most common reasons people enquire about our roof spraying service.
Certain roof coatings also contribute to improved energy efficiency. Reflective roof coatings reduce heat absorption through the roof space during summer, which lowers demand on air conditioning inside the property. That improved energy efficiency is particularly relevant for homes that see significant sun exposure through the warmer months.
Both of these follow from the same outcome: roof coatings that are doing their job properly across the entire roof. Energy efficiency gains might not be visible the way kerb appeal is, but over a warm summer they add up.
Roof coating colours range from traditional terracotta and blended reds through to slate grey and darker charcoal finishes. Slate grey is the most requested colour we apply, particularly where roof tiles have faded unevenly and the original shade no longer looks consistent across the surface.
If you want to change the look of your roof rather than simply refresh the existing tone, that is possible with the right protective roof coating product. We can discuss colour options when we carry out the roof spray assessment and advise on what works well for your property type and roofing materials.


We have worked on roofs across the North East and North Yorkshire long enough to understand what the climate demands here. Persistent damp, frost and organic growth make quality roof coatings more important in this part of the country than in drier regions. As an experienced jet washing company, we understand how important proper roof preparation is before any coating work begins.
Every job starts with a proper assessment of whether our roof spraying service is the right fit for your tiles. If the roof needs cleaning first, we handle that as a separate services roof coating and preparation stage and can direct you to our roof cleaning page for more on that. After cleaning, is roof coating the right next step? In most cases, yes. If roof sealing is also needed, we offer that too.
We use roof paint that is high quality paint matched to your specific tile type, not a generic product off the shelf. The roof paint we use is selected for durability in the North East climate specifically. The roof coating applied by our team is the same standard whether we are working on a terrace or a larger detached home. An extended roof lifespan starts with the preparation, and that is where we spend our time before a single coat goes on.
We apply roof coatings the same way on every job: thorough prep, proper drying time and professional application from start to finish.
If your roof tiles are faded, mossy or looking worn, our roof coating service could be exactly what the property needs. Northern Powerwash provides a roof spraying service across the North East and North Yorkshire, and we offer free no-obligation quotes for all roof spraying projects.
Is roof spraying the right choice for your property? Is roof coating worth it compared to replacing the roof? In most cases where the existing roof is sound, yes. Get in touch with Northern Powerwash today. We will look at your roof, give you an honest recommendation and provide a clear price for the work.
