Roof Cleaningin Hurley
Hurley sits between the Thames and open countryside, so its roofs take damp from one side and wind-blown debris from the other. We clean old clay and later concrete alike with care, and finish every roof with Chiltern EverGuard™.

Our approach
Old roof details are checked first before anything is cleaned
Many roofs in the village are older than they look from the lane. Ridge tiles bedded in mortar, mortared verges and handmade clay tiles all weather with age, and some are more fragile than the moss on them suggests. We identify those details at a free site visit, so the method is set around them rather than discovered halfway through the job.
Hurley roofs
Between the river and open countryside
Hurley lies on the Thames a short way upstream of Marlow, with open fields and countryside around it. That setting works on a roof from two directions: damp air off the river keeps slopes wet, while the wind carries leaves, seed and organic dust in off the land. Exposed roofs here pick up lichen and moss sooner than the same tiles in a sheltered street.
The housing mixes village homes and period cottages with riverside houses and larger country properties along narrow private lanes. Older buildings often carry handmade clay tiles and mortar-bedded ridges, later ones concrete. Garages, porches and outbuildings add roofs of their own, and on many properties they are the ones that look most neglected.
Mortar and ridges
Weathered mortar at the ridge and verge
Ridge tiles, hips and verges on older roofs are often bedded in mortar, and mortar weathers. It can crack, crumble at the edges or loosen behind a ridge tile without that being obvious from the ground. Moss tends to settle along exactly those lines, so it has to be removed from them carefully.
We check the bedding at the site visit, lift the moss from mortar lines by hand and keep any cleaning there gentle. Where mortar is already failing, we tell you before work begins; repointing is a job for a roofer, and cleaning is no substitute for it.
Clay tiles
Handmade clay that has softened with age
Handmade clay tiles vary in thickness, colour and finish, and after many decades on a roof some become porous and brittle at the edges. Pressure that a modern concrete tile shrugs off can strip their surface or crack them outright. On these roofs, moss is removed by hand and the clay is soft washed, letting the treatment do the work rather than the water.
Their natural tonal variation is part of what makes them attractive, and we do not try to clean it away.
Smaller roofs
Porches, bays and outbuildings deserve the same care
Secondary roofs often face a different way from the house, sit beneath its higher slopes or stand under trees at the edge of the garden. They catch more run-off and less sun, and they frequently look worse than the main roof as a result.
- Porch and bay roofs: cleaned with the main roof in one sequence
- Garages and outbuildings: assessed for their own covering and condition
- Dormers and roof windows: worked around frames, seals and lead
- Lower roofs cleared of debris that fell from above
Treatment
Chiltern EverGuard™ on exposed and sheltered roofs alike
The Chiltern EverGuard™ Treatment is applied to every roof we clean, including the smaller ones. It reaches into the surface to target spores and remaining growth, and it helps reduce how quickly moss, algae and lichen re-establish.
Protection typically lasts between 12 and 24 months, varying with exposure, shade and the covering itself. It needs settled, frost-free weather, so in a cold spell we take the moss off and return to apply it. We email as the protection period ends to offer a free reassessment.
How it works
From lane access to handover in five stages
Every roof follows the same five stages. On a village or country property, access along private lanes is settled at the first of them.
- 01
Site visit, access and drone view
We look at the roof, the mortar details and the lane access, using a drone where appropriate and showing you live footage of tiles you cannot see from below.
- 02
A clear quotation in writing
You receive a report with our recommended method for each roof, the reasons for it and a defined statement of works, together with a clear quotation.
- 03
Moss removed by hand
Working from towers, platforms or poles rather than the roof itself, operatives lift the moss by hand, taking extra care along ridges, verges and around older clay.
- 04
Soft wash or low-pressure clean
Each roof is cleaned in the way its tiles can stand, from a soft wash on fragile clay to a low-pressure clean on concrete, followed by the Chiltern EverGuard™ Treatment.
- 05
Debris cleared and handover
Moss is cleared from the gutters, lower roofs and paths, downpipes are checked, and the project lead explains what was done and what the aftercare involves.
Plain facts
Cleaning shows the roof's history, it does not erase it
Taking off the moss reveals the roof as it really is. Weathered mortar, older repairs, replacement tiles that do not quite match and the natural colour range of clay all become easier to see. That is useful to know about, but none of it is changed by cleaning, and repairs remain a separate job for a roofer.

Questions
Roof Cleaning in Hurley: your questions
Can you clean old handmade clay tiles?
Yes, with care. Moss is lifted by hand and the clay is soft washed rather than pressure cleaned, because age leaves handmade tiles porous and sometimes brittle. If they are too fragile to clean, we say so at the site visit.
Will cleaning damage the mortar on my ridge?
No, not when sound mortar is handled properly. Moss is removed from mortar lines by hand and any cleaning there is gentle. Where bedding is already cracked or loose, we point it out before work starts.
Do you clean garage and outbuilding roofs?
Yes, where access is safe. Smaller roofs are assessed for their own covering and condition and can be included in the same visit, so the whole property is finished together.
Why does my roof go green faster than houses in town?
Exposure works both ways here. Damp air from the river keeps roofs wet, and wind off open countryside brings leaves, seed and organic dust that feed growth. Together they let moss and lichen establish quickly.
Can you reach a property down a narrow private lane?
Usually, yes. Turning, parking and where access equipment can stand are checked at the site visit, so the crew arrives with a plan rather than working it out on the morning.
Will the roof look even straight after cleaning?
Not always. Natural colour variation in clay, older repairs and some residual staining can remain, and treated growth often fades gradually afterwards. We aim for a clear improvement suited to the roof's age.
How long does Chiltern EverGuard™ protection usually last?
Typically between 12 and 24 months, depending on exposure, shade, the tile and maintenance. As the period draws to an end we email you and offer a free reassessment of the roof.
