What roof spraying actually involves
Roof spraying is the application of a coloured, water repellent coating to cleaned roof tiles. It is sprayed on in even coats after manual moss removal and a biocide treatment, restoring a consistent colour to faded tiles and making the surface shed water faster. It protects and improves the look of a roof that is structurally sound. It does not fix cracked, slipped or delaminating tiles, and it is not an alternative to re-roofing.
Roof spraying is a coating, and it is worth being straight about that. It goes on after the roof has been cleaned, and it does two things: it puts an even colour back onto tiles that have faded, and it leaves a water repellent film that slows down how quickly algae and moss get a grip again. That is the honest description. It is not a repair, it is not a membrane, and it adds nothing structural to a tile that is already breaking up.
Concrete tiles are the ones that benefit. They are made with a pigmented slurry on the face, and after twenty or thirty Lancashire winters that face is porous, patchy and grey. A coating restores the colour and closes the surface back up. On clay and natural slate there is far less to gain, because those materials do not fade in the same way, and we will tell you that rather than sell you a coating you do not need.
We only spray a roof that we have cleaned ourselves, because the coating is only ever as good as what is underneath it. Moss, lichen and loose slurry have to come off first, or you are painting over the problem and it will flake within a couple of seasons. Where tiles are cracked, delaminating or slipping, the right answer is a roofer, not a spray gun. We would rather turn the work down than coat a covering that needs replacing.
Suitable for
- Faded concrete interlocking tiles that have gone patchy and grey
- Roofs where the covering is intact but the colour has weathered out
- Houses being prepared for sale, where kerb appeal earns its money
- Bungalows and dormers where the roof is most of what you see from the road
- Roofs that have just been cleaned and are in good order
- Garage and extension roofs that no longer match the main house
Problems it solves
- Faded, blotchy concrete tiles that make a well kept house look neglected
- A roof that greens up again quickly after every clean
- Porous tile faces that soak up rain and take days to dry out
- Mismatched colour where tiles have been swapped in over the years
- Wanting the roof to look right without the cost and upheaval of a re-roof
How we approach roof spraying
Survey and honest assessment
We get up and look at the tiles first. Sound tiles, and a coating makes sense. Cracked, delaminating or slipping tiles, and we tell you a roofer is the right call and do not quote for spraying.
Full roof clean
Moss and lichen are removed by hand, the gutters and downpipes are cleared, and a biocide treatment goes on. Nothing gets coated until the covering is genuinely clean and the surface underneath is stable.
Preparation and drying
Loose or displaced tiles are flagged, ridge bedding and flashing issues are pointed out, and the roof is left to dry through. A damp or dusty surface will not hold a coating however good the product is.
Masking and protection
Gutters, flashings, rooflights, solar panels, walls and everything on the ground below are masked and sheeted. Overspray on a neighbour car is the quickest way to spoil an otherwise good job.
Coating applied in coats
The coating is sprayed in even passes, normally more than one, working methodically across the pitch. Coverage is checked as we go, so there are no thin patches at the ridge or heavy runs at the eaves.
Final inspection
Masking comes off, gutters are checked again for overspray and debris, and we walk you round the outside in daylight so you can judge the finish from where people actually see it.
What you get
- Even colour restored across tiles that have weathered unevenly
- Water sheds off a sealed face, so the tile dries out sooner after rain
- Slower return of moss and algae compared with cleaning on its own
- A noticeable lift in how the whole house reads from the street
- Far less cost and disruption than replacing a covering that is still sound
- Work only quoted where the roof is genuinely suitable for it
