Moss lifted from tiles and slate by hand, then treated with an appropriate treatment or soft-wash treatment. No high pressure is used on the roof covering, and the gutters are cleared before we leave.
The problem
Moss holds water against the roof covering long after the rest of the roof has dried. On concrete tiles that accelerates surface erosion; on slate it lifts and works into the laps; and on any roof it adds weight the covering was never intended to carry saturated.
The bigger nuisance is what happens below. Moss breaks away in wind and rain, washes into the gutter line and blocks outlets and downpipes, which is a common cause of overflowing gutters and damp staining at fascia level.
Pressure washing a roof is the wrong tool. It drives water under the laps, strips granules from concrete tiles and can dislodge bedding on ridges and hips. Removing the growth mechanically by hand and then treating what remains is slower, and it is the method that does not shorten the life of the roof.
Roof cleaning removes moss and organic growth from tiles or slate. Heavier moss is removed by scraping where appropriate, then the covering is treated with an appropriate treatment or soft-wash treatment so regrowth is slowed. Gutters and downpipes are cleared afterwards, because moss debris ends up there.
Roofs are not pressure washed as a standard method. Moss is removed by hand and with appropriate tools, and the treatment does the rest over the following weeks as the remaining growth dies back and weathers off.
Our method
The covering, pitch, access and existing condition are checked from ground level and from height where safe access allows.
Safe access is set up, and gutters, glazing, planting and surfaces below are protected.
Heavier moss is scraped and brushed off the covering without high pressure, working with the lap of the tiles or slates, where appropriate for the covering and its condition.
An appropriate treatment or soft-wash treatment is applied at low pressure to reach growth left in the surface of the covering.
Gutters, downpipes and the ground below are cleared of moss debris and washed down.
Photographs are taken from height, any defective tiles or flashings we noticed are reported, and we explain what happens over the following weeks.

Surface care
Being straight with you
Where a surface would genuinely benefit from protection once it is clean and dry, ask about exterior surface sealing.
Before we start
The right method for the surface, not simply more pressure. Before anything is switched on we look at what we are actually cleaning: the material, the contamination on it, the condition it is already in, and whether there is cracking or earlier repair work that needs treating carefully.
We also check the practical side. An outside tap is preferred so we do not have to run hoses through your home; where an indoor tap is needed, we agree a safe hose route, take the hose out carefully and keep the connection monitored and secure. The water flow affects how quickly our equipment or water tank refills. We look at where the water will travel, whether there is a suitable drain or gully, and whether anything is likely to pool. Access, nearby walls and render, planting and delicate areas are all noted so they can be protected or worked around.
If there is no outside tap, it helps to mention it when you enquire. It is easily worked around, but it is better known in advance than found on the morning.
Photographs and existing damage
We often photograph the area before we begin — loose or cracked roof tiles, loose pointing at ridges and verges, and heavy moss build-up. It gives an honest record of the property's condition, and it gives you a genuine before-and-after comparison once the work is finished.
If we find a defect, we would rather point it out than quietly clean over it. We will show you what we have found, adjust the method around the weaker area where that is sensible, and if continuing could do more harm than good we will stop and talk it through. Sometimes the right advice is to have another suitable tradesperson look at it first.
We would rather work carefully around a problem than knowingly make it worse.
What to expect
Cleaning can make a very large difference, but it cannot undo age. Weathering, worn surfaces, permanent staining, previous repairs and colour variation may still be visible afterwards. What we aim for is the best sensible improvement from the existing surface, and we will say so before we start if we think the result will be limited.
Moss taken off a roof has to go somewhere, so gutters and outlets are worth checking at the same time. See gutter clearing.
