Roof Windows — Long Crendon
Local Roof Windows 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 Windows in Long Crendon — What Makes It Different
Velux installation on Long Crendon conservation area and listed building properties requires planning permission and listed building consent respectively. The presumption in conservation areas is against new roof windows on visible elevations — rear slope windows on slopes not visible from a public road have a better prospect of approval. EDW conservation flashings are standard for approved installations.
What We Find in Long Crendon
The Long Crendon planning risk: proceeding with a Velux installation on a listed property without listed building consent. This is an offence under the Planning (Listed Buildings and Conservation Areas) Act 1990 and can result in an enforcement notice requiring removal at the homeowner's expense. We confirm the consent position before discussing installation.
Our Approach to Roof Windows in Long Crendon
Planning and listed building consent confirmed before any discussion of product or programme. We can advise on what is likely to gain approval — rear slope, EDW conservation flashing, modest size — and help formulate the correct planning application question. We do not install roof windows on Long Crendon properties without confirmed consent.
How We Work
The Roof Windows Process in Long Crendon
Survey and planning check.We measure rafter spacing, confirm roof pitch, and advise on the correct Velux size and flashing type. We check whether installation is permitted development or requires planning permission — this varies by property location, elevation, and conservation area status.
Structural assessment.Standard Velux installation requires opening between two rafters and trimming the top and bottom. We confirm rafter depth and spacing before ordering. Non-standard rafter spacing requires a structural trimmer — we identify this at survey, not on installation day.
Supply and installation.Window supplied, opening formed, rafters trimmed, insulated reveal formed internally. Velux EDW or standard flashing kit installed and dressed into the surrounding tile. Internal boarding completed. Most standard installations take four to six hours.
Weatherproofing test.We test the flashing seal before leaving — running water over the junction and checking the internal reveal for any ingress. Open and close operation checked. Internal and external completion signed off.
Dual guarantee.Velux 10-year product warranty plus our 10-year installation workmanship guarantee. Both issued in writing.
Every job starts with a free survey. Call 0129 670 6028 to book yours.

A roof window is a straightforward upgrade done right. Here is what to consider before fitting one.
A dark loft, landing or extension that needs natural light
An existing roof window that leaks around the flashing
A loft conversion needing light and ventilation
A tired or fogged old skylight due for replacement
A room that would benefit from overhead rather than wall light
When it is not the answer: If your rafter spacing or a conservation-area position makes a standard install impractical, we will say so at survey rather than forcing an installation that will not sit right. Read the full guide.

Good to know
What It Is Like While We Work
A few hours of work with some internal dust around the opening; we sheet up and clean down. You do not need to stay home for external work - we just need power and access agreed in advance.
Installations run year-round; the opening is kept weathertight at every stage. 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."
Gilbert A. · 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."
Gilbert A. · 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."
