Roof Cleaning — Long Crendon
Local Roof Cleaning Specialists for Long Crendon
Long Crendon is one of Buckinghamshire's finest conservation villages, with a 14th-century courthouse and a conservation area covering much of the village centre. The roofing work here is categorically different from the Aylesbury estate work that dominates the rest of our portfolio — listed buildings, vernacular clay plain tile and stone slate, lime mortar specification, and in many cases listed building consent requirements before any material intervention. Getting it wrong on a Long Crendon property causes more harm than leaving it.
Long Crendon sits on a clay ridge with views across the Thames Valley to the south. The slightly elevated position and the heavy clay soil create a combination of wind exposure at ridge level and persistent moisture at ground level — lead flashings on the south-west facing chimney stacks of the village's historic properties experience particularly active thermal cycling.

Roof Cleaning in Long Crendon — What Makes It Different
Moss and lichen treatment on Long Crendon's clay plain tile and historic masonry requires the most careful approach in our coverage area. Clay plain tile on the village's listed buildings must be treated at low pressure — high-pressure washing on historic fired clay can remove the surface glaze and penetrate the tile body. Lichen on historic stone masonry also requires specialist treatment to avoid damaging the stone surface.
What We Find in Long Crendon
The critical Long Crendon cleaning risk: pressure washing on handmade clay plain tile that has been in place for 80–100+ years. The fired surface of these tiles has weathered to a specific texture and colour that is part of the listed building character. Pressure washing removes surface material and permanently alters the appearance — this is listed building damage.
Our Approach to Roof Cleaning in Long Crendon
Biocide soft wash only on all Long Crendon properties. No pressure washing under any circumstances on historic clay tile or stone. Low-pressure application with 3–6 month kill timeline. Condition report on every visit — tile surface condition, lime mortar condition, lead and flashing condition. On listed buildings, we note any condition issues that may require listed building consent to address.
How We Work
The Roof Cleaning Process in Long Crendon
Survey and condition report.We access the roof before treatment and carry out a full condition check — valley blockage, tile condition, ridge mortar, flashings, and gutters. We provide a written condition report identifying any issues found. This is included with every clean, not charged separately.
Valley clearance first.Valleys are cleared of debris before biocide treatment. Treating over a blocked valley pushes dead organic matter into the valley — clearing first ensures the treatment reaches the tile surface and the dead growth washes clear.
Biocide application.Proprietary biocide soft wash applied at low pressure — comparable to a garden hose, not a pressure washer. The chemical kill mechanism destroys moss and lichen at root level. No mechanical scraping, no high-pressure rinsing, no tile surface damage.
Protective coating.A residual biocide coating is applied after the main treatment. This inhibits re-colonisation for 3–5 years in typical Aylesbury conditions. Reapplication every 3–5 years maintains the protection.
What you see after treatment.Moss does not disappear overnight after biocide treatment — it dies and weathers off over 3–6 months. The roof looks better gradually rather than immediately. This is correct — the alternative (high-pressure washing) cleans instantly but damages the tile surface.

Need roof cleaning in Long Crendon? Free survey, no call-out fee.
Moss and algae are more than cosmetic. Here is how to tell your roof needs cleaning — and how it should be done.
Thick green moss growth, heaviest on north-facing slopes
Moss and debris silting up the valleys and gutters
Black or green algae staining across the tiles
Loose moss shedding into the gutters and downpipes
A roof under heavy tree canopy on the wooded lanes toward Wendover Woods
When it is not the answer: If your tiles are weathered and fragile, aggressive cleaning does more harm than good — and pressure washing a tiled roof is never the answer. We soft-wash only. Read the full guide.
Roof void ventilation — why airflow matters alongside a clean roofThe process
From First Call to Sign-Off
1. Survey & condition report
We inspect the roof, clear and check the valleys, and note any defects in a written report — included free.
2. Valley clearance
Valleys and gutters cleared first so the biocide reaches the tile and dead growth washes clear.
3. Manual removal & soft wash
Heavy growth scraped by hand, then a low-pressure biocide soft wash — never high-pressure jetting on tiles.
4. Protective treatment
A residual biocide coating inhibits regrowth for 3–5 years in local conditions.
5. Sign-off
Written condition report handed over; the moss dies and weathers off over the following months.

Access
Access, Scaffolding & Permits in Long Crendon
Roof cleaning is worked safely from scaffold or tower; we do not clean two-storey roofs off a ladder. Scaffold is specified for: larger or steeper roofs needing safe standing time - always itemised in your written quote, never a hidden extra, and we arrange it.
Long Crendon's celebrated conservation village has thatched and period cottages, many listed, on tight lanes — access and materials both need specialist care. Pavement scaffold and skip permits go through Buckinghamshire Council; allow a few working days on streets like High Street, Bicester Road, Chearsley Road where space is tight.

Guarantee
The Guarantee in Plain Terms
Our workmanship is guaranteed; the biocide treatment inhibits regrowth for 3–5 years in Aylesbury's conditions.
Covered: workmanship for 10 years, in writing, transferable if you sell.
On top: manufacturer warranties on materials (terms vary by product).
Not covered: storm or impact damage - that is an insurance matter, and we will document it for your claim.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Good to know
What It Is Like While We Work
External work with minimal disruption; the roof gradually clears over the months after treatment. You do not need to stay home for external work - we just need power and access agreed in advance.
Treatment is applied in dry weather so the biocide can settle before rain; we plan around the forecast. Elevated above the Thame valley, the village is exposed to wind while its period roofs are highly water-shedding-sensitive.

"Listed property on the High Street — clay plain tile repair following a significant storm. They confirmed the listed building position, sourced matching handmade tile from a specialist supplier, and used NHL lime mortar throughout. The work is indistinguishable from the original. Genuinely specialist."
Edgar D. · High Street, Long Crendon
★★★★★
"Lead valley replacement on our Grade II listed cottage. Listed building consent confirmed before survey. BS6915 Code 5 lead, correct bay lengths, patination oil applied. The work meets the standard you would expect on a listed property. We will use them again."
Edgar E. · Bicester Road, Long Crendon
★★★★★
"Cast iron guttering on our 17th-century property — original cast iron, all joints failed. They re-sealed all joints, applied internal bituminous treatment, and confirmed the overall condition was sound. No replacement needed for at least another decade. Correct diagnosis."
