Slate Roof Soft Washing in Marlow
Lichen and algae had dulled the slate on a timber-framed Marlow property. Soft washing from a tower brought the stone back without walking the roof or disturbing a single slate.
Roof Cleaning
Low-pressure roof cleaning and Chiltern EverGuard™ treatment across Buckinghamshire, Berkshire & Oxfordshire — moss, algae and organic growth removed using the method and the pressure that suit your tiles.

Roof Cleaning
Moss and algae build up on a roof, mark the tiles and end up in the gutters. We take the growth off by hand first, clean at low pressure, then apply Chiltern EverGuard™. We look at the roof at the site visit and choose the method and the pressure that suit it, whether it is clay, slate or concrete.
Our approach
We use the lowest possible pressure and the least amount of chemical necessary to achieve the right result. This may sometimes require additional applications or a more considered process, but we believe that is always preferable to taking the quickest or most aggressive approach. Our priority is to achieve the best possible result while protecting the surface and surrounding environment.

What we do
Clay, concrete and slate all weather differently, so we look at what is actually on your roof before deciding how to clean it. The method and the pressure are set at the site visit.
The moss is taken off by hand first, then the roof is soft washed at low pressure and Chiltern EverGuard™ is applied. It takes longer than going at it with pressure, and we think that is the right trade.

Step one
Thick moss is taken off the roof physically. Every clump is worked loose by hand and scraper, tile by tile, working down the slope.
It is the slow part of the job, and we do it before anything is sprayed — a treatment applied over thick moss leaves the moss where it is.
Our roof cleaning service
Every property is different. We start with a free site visit, assess the surfaces, then choose the method and the pressure that suit them.
We inspect the roof, the tile type, the access and the drainage, then set the method and the pressure to suit it.
Moss is removed by hand and scraper, working down the slope, so the tile surface and the bedding underneath are left alone.
Controlled, low-pressure cleaning lifts the algae and the grime, with the water kept running down the roof.
Chiltern EverGuard™ is applied across the roof once it is clean. Protection typically lasts between 12 and 24 months, depending on the property's location, surrounding environment, surface type and ongoing maintenance.
Everything taken off the roof ends up in the gutters, so we clear them out and leave the property as we found it.
Tile by tile
Hand-made and machine-made clay. The moss is taken off by hand and the tiles are cleaned at low pressure.
Cleaned at low pressure once the moss has been taken off by hand, then finished with Chiltern EverGuard™.
Worked down the roof by hand, with the water kept running down the slope.
Man-made slate. A gentle soft wash lifts the algae off the surface.

Only then
With the bulk of the moss removed, the roof is soft washed at low pressure to lift the algae and the staining left behind, then Chiltern EverGuard™ is applied across the whole slope.
Working from a pole keeps the weight off the tiles and keeps the water travelling down the roof.
Why it matters
The moss is taken off by hand before anything is sprayed.
A clean roof changes how the whole property looks from the street.
Applied to every roof once it is clean. Protection typically lasts between 12 and 24 months.
Clay, slate and concrete are each cleaned at the pressure that suits them.

Questions
No. We look at the roof at the site visit and set the method and the pressure to suit the material. Clay, concrete and slate are all handled differently.
Yes. The moss is taken off by hand first, and Chiltern EverGuard™ is applied to the cleaned roof afterwards.
Chiltern EverGuard™ protection typically lasts between 12 and 24 months, depending on the property's location, surrounding environment, surface type and ongoing maintenance. We'll give you our view of your roof at the site visit.
The lowest pressure that will achieve the right result on that roof, decided at the site visit once we have looked at the tiles and their condition.
Yes, as standard. Everything we take off the roof washes into the gutters, so leaving them full would simply move the problem. We clear the run and check the downpipes before we finish.
Moss removal can be carried out through the year. We apply Chiltern EverGuard™ in settled, frost-free conditions, so in hard weather we'll carry out the removal and come back to treat.
