Windsor Roof Surveys provide independent, certified roof inspections across this historic royal borough and its surrounding districts. Our survey team combines drone aerial photography with thermal imaging technology to deliver precise, detailed assessments of every roof type found in the shadow of the Castle — from the handsome Georgian townhouses lining the streets around the High Street and Park Street, through the substantial Victorian villas of Clewer Village, the interwar family homes spread across Dedworth and the roads leading towards Old Windsor, to the post-war estates of Clewer New Town and the riverside properties that sit within the Thames floodplain.
Fast, independent roof surveys from local experts.
Windsor Roof Surveys exist because this town's building stock is among the most architecturally diverse in the Thames Valley. Properties here range from medieval timber-framed structures in the oldest streets near the Castle, through the elegant Georgian terraces built during the town's expansion as a royal residence, to the Victorian villa developments that followed the arrival of the railway. Add the ribbon of Edwardian housing along the Maidenhead Road, the 1930s semi-detached estates in Dedworth, and the concrete-tiled post-war developments in Clewer New Town, and you have a roofing landscape that demands specialist, era-specific knowledge. Windsor Roof Surveys bring exactly that expertise to every inspection.
Whether you are purchasing a listed property in the conservation area, investigating recurring damp in an interwar house, supporting an insurance claim after Thames Valley storms, or evaluating an ageing roof before committing to expensive remedial work, our surveys provide the documented evidence that informed decisions require.
Windsor Roof Surveys were established on a principle that applies here as strongly as anywhere in the country: homeowners deserve honest, independent information about the condition of their roof before spending a single pound on repairs. Too many Windsor property owners have been quoted for unnecessary work by contractors whose income depends on the outcome, or have exchanged on a purchase only to discover defects that a proper inspection would have caught weeks earlier.
Our methodology begins with a thorough ground-level perimeter walk, checking rainwater goods, fascia boards, soffits, and any visible defects from street level. Our DJI Enterprise drone then captures high-resolution imagery of every elevation, ridge line, valley, hip, flashing joint, and chimney stack — delivering perspectives that scaffolding cannot match on Windsor's taller Georgian townhouses and the steeply pitched Victorian rooflines characteristic of the streets around Alma Road and Frances Road. Where the survey package includes thermal scanning, our FLIR cameras map moisture patterns concealed within the roof structure and beneath tile or slate coverings.
The roofing challenges in Windsor vary enormously within a short walk. A Georgian property on Park Street will present handmade clay peg tiles, lime mortar bedding, and lead-dressed parapet gutters that behave entirely differently from the machine-made clay tiles on a 1930s Dedworth semi or the concrete interlocking tiles covering a 1960s terrace in Clewer New Town. Windsor Roof Surveys have the training and the local knowledge to read each material correctly and report on its true condition.
Independence is central to everything we do. Windsor Roof Surveys do not undertake roof repairs and have no commercial interest in the outcome of any inspection. When we confirm a roof is performing well, clients can trust that assessment without reservation. When we identify a problem, our costings reflect genuine current trade rates for the materials and labour involved — not inflated figures designed to generate urgency.

Homeowners in Maidenhead and Slough face comparable problems with ageing slate, interwar tile fatigue, and riverside moisture exposure. See our area-specific guides for information tailored to your location.
Windsor Roof Surveys are not roofers, builders, or contractors. We provide independent inspection and reporting only — ensuring every assessment is free from commercial bias.
Windsor Roof Surveys are ready to inspect your property. Whether it is a listed Georgian townhouse near the Castle, a Victorian villa in Clewer Village, or a family semi in Dedworth, our team delivers the clarity you need.
What Windsor Roof Surveys bring to homeowners, buyers, and landlords across the royal borough
Windsor presents unique access challenges for roof inspection. The tight Georgian terraces along Castle Hill and Thames Street leave no room for scaffolding, while the tall Victorian properties around Alma Road and Frances Road have steeply pitched rooflines that ladders cannot safely reach. Our DJI Enterprise drone photographs every ridge, valley, hip, flashing, and chimney stack in high definition — capturing defects that are invisible from the pavement and unreachable by conventional means.
Windsor's position beside the Thames means higher ambient humidity and frequent morning river mist — conditions that promote slow, concealed moisture ingress through ageing tile coverings and degraded flashings. Our FLIR thermal cameras detect the temperature differentials that indicate trapped moisture beneath slates, behind lead work, and within timber roof structures, identifying problems months before they produce visible internal staining.
Every Windsor Roof Surveys report is assembled as a comprehensive, evidence-based document. High-resolution drone photographs are annotated to pinpoint specific defects, thermal overlays highlight moisture paths, and all recommended repairs are costed at current trade rates. The finished report serves equally well as evidence for a solicitor during property negotiations, as documentation for an insurance claim, or as a precise specification for a roofing contractor.
Windsor Roof Surveys hold full professional indemnity and public liability insurance. Our surveyors carry recognised industry certifications and CAA-approved drone pilot licences. Every inspection follows a standardised methodology developed across thousands of properties, ensuring consistent accuracy whether we are assessing a medieval building within sight of the Castle walls or a modern apartment block beside the railway station.
Windsor is not a single type of town — it contains several distinct neighbourhoods, each with its own architectural character and roofing materials. The historic core around the Castle and the High Street features Georgian townhouses with handmade clay peg tiles, lead-dressed parapet gutters, lime mortar ridging, and tall chimney stacks — many of them listed. The Victorian streets radiating from the station and through Clewer Village present Welsh slate, ornate ridge tiles, and decorative bargeboards. Dedworth's interwar housing carries machine-made clay tiles on steep pitches with bay window lead work prone to fatigue. Clewer New Town's post-war estates use concrete interlocking tiles with a finite service life.
Windsor Roof Surveys understand these distinctions because we have inspected properties across every one of these neighbourhoods. We do not rely on a generic assessment template — each survey is tailored to the age, material, and construction method of the roof we are examining. That targeted approach is what separates a report that actually helps you from one that simply confirms a roof is present.
From the Georgian peg tile roofs near the Castle to the concrete tiles of Clewer New Town, Windsor Roof Surveys know this royal borough's roofscape thoroughly.
How Windsor Roof Surveys have helped local homeowners and property buyers
A couple purchasing a Grade II listed Georgian townhouse on Park Street received a homebuyer report that described the roof as "satisfactory for a building of this age." With an asking price above one and a quarter million pounds, the buyers felt this vague assessment left too many unanswered questions. They instructed Windsor Roof Surveys to provide a detailed independent inspection before exchanging contracts.
Our drone captured a concealed parapet gutter running along the rear elevation — entirely hidden from ground level by the raised front parapet wall. The lead lining had cracked along a two-and-a-half-metre section, and thermal imaging confirmed active moisture migration into the roof timbers below. We also documented eroded lime mortar bedding on both chimney stacks, three displaced handmade peg tiles on the rear slope, and corroded rainwater hopper heads on the side elevation.
Windsor Roof Surveys estimated total remediation at approximately twelve thousand eight hundred pounds. The buyers' solicitor submitted our report and the vendor accepted a price reduction of the full amount. The lead parapet gutter was replaced using heritage-grade materials within eight weeks of completion, preventing structural timber damage that would have escalated rapidly through another winter season.
Following severe storms in autumn 2024, a Dedworth Road homeowner discovered water pouring into the front bedroom through the ceiling rose. Their insurance company sent a loss adjuster who attributed the damage to "long-term maintenance failure" and rejected the claim entirely. Frustrated and facing a significant repair bill, the homeowner contacted Windsor Roof Surveys for an independent opinion.
Our drone inspection documented seven freshly displaced clay tiles on the south-west facing slope — the orientation directly exposed to the recorded storm wind direction. The fracture edges were clean and unweathered, confirming recent breakage rather than gradual deterioration. Thermal imaging traced a clear moisture path from the displaced tiles through to the bedroom ceiling immediately below. We also identified that the ridge mortar along the affected slope had been disturbed by wind uplift, with sections of dry verge mortar blown out cleanly.
The Windsor Roof Surveys report — with timestamped photography, thermal evidence, and a clear distinction between storm-caused damage and pre-existing wear — was submitted to the insurer as a formal dispute. The claim was reassessed and approved in full within four weeks. Repair costs of five thousand six hundred pounds were covered under the policy. The homeowner would have been left paying the entire amount without the documented evidence our inspection provided.
The owner of a detached Victorian villa in Clewer Village received a contractor quote of twenty-six thousand pounds for a complete strip and re-slate of the entire roof. The contractor spent twenty minutes on site with a ladder and declared the whole covering "past saving." The homeowner was sceptical of such a sweeping assessment and asked Windsor Roof Surveys to investigate independently before committing to the expense.
Our comprehensive survey — drone photography of every elevation combined with an internal loft space inspection — revealed that the front and both side elevations were in sound condition with the original Welsh slate performing well and fixings still secure. The rear slope, however, showed widespread nail fatigue causing progressive slate slippage, degraded felt underlay visible from the loft, and a failed lead soaker along the abutment with the rear addition. Only the rear elevation needed intervention.
Windsor Roof Surveys costed the rear slope re-slate and abutment lead replacement at approximately twelve thousand pounds — less than half the original quotation. The homeowner instructed the work on the rear elevation only, based on our detailed specification. The front and side slopes continue performing well, and our report provides a clear maintenance schedule for monitoring their condition over the coming years.
The owners of an Edwardian property in Old Windsor had been battling recurring damp in their first-floor rooms for over a year. Two separate damp-proofing companies diagnosed rising damp from the Thames water table and quoted for extensive tanking works costing over fifteen thousand pounds. The owners remained unconvinced and contacted Windsor Roof Surveys before agreeing to any remedial scheme.
Our thermal imaging scan — conducted from both drone altitude and internally within the loft space — revealed that the moisture was entering from above, not rising from below. A cracked lead step flashing where the main roof met a rear bay projection was channelling rainwater behind the wall plate and into the first-floor wall cavity. The damage pattern mapped precisely onto the internal staining. The Thames water table was not a factor at all.
The lead step flashing replacement cost approximately two thousand three hundred pounds. The first-floor damp dried out entirely within six weeks of the repair. Had the owners accepted the tanking diagnosis, they would have spent over fifteen thousand pounds on invasive work that would not have addressed the actual cause. The Windsor Roof Surveys report saved them thousands and identified the real source of the problem.

Feedback from homeowners and buyers who have used Windsor Roof Surveys
"We were buying a Georgian townhouse near the Castle and knew the homebuyer survey would not cover the roof properly. Windsor Roof Surveys found a cracked parapet gutter lining and deteriorated lead flashings that would have cost over eleven thousand to repair. Their evidence gave our solicitor the leverage to negotiate a significant price reduction. Cannot recommend highly enough."
"Damp above the bay window in our Dedworth Road semi had been getting worse for months. Two roofers gave contradictory opinions. Windsor Roof Surveys traced it using thermal imaging to a failed lead apron behind the chimney stack — something neither tradesman had examined. Repaired within a fortnight of receiving the report and the problem has not come back."
"A contractor wanted twenty-six thousand for a complete re-slate on our Clewer Village house. Windsor Roof Surveys proved that only the rear slope actually needed replacement — the front and sides were sound for years to come. Saved us nearly fourteen thousand pounds and gave us a clear maintenance plan going forward. Honest, thorough, and genuinely independent."
How Windsor Roof Surveys help property owners navigate insurance claims and disputes
Windsor's Thames-side position and exposure to prevailing south-westerly weather systems make storm damage claims a regular occurrence across the borough. When tiles are displaced, flashings are torn, or chimney stacks are damaged by high winds, the difference between a successful claim and a rejected one almost always comes down to the quality of the documented evidence. Windsor Roof Surveys produce reports specifically structured to meet the evidentiary standards that insurers require.
Every comprehensive and premium inspection generates timestamped drone photography — capturing the exact condition of the roof at the time of our visit. Thermal imaging overlays identify active moisture ingress paths. Crucially, our reports distinguish clearly between damage caused by a specific weather event and pre-existing wear or gradual deterioration. This distinction is precisely what loss adjusters scrutinise when assessing whether a claim falls within policy coverage.
We have supported Windsor homeowners through dozens of successful insurance claims, including cases where an initial claim was rejected by the insurer's appointed loss adjuster. In several instances, our independent evidence — presented as a formal dispute — led to the original decision being overturned and the full claim being approved. The cost of a Windsor Roof Surveys inspection is typically a fraction of the repair costs that a successful claim recovers.
Beyond insurance work, our reports serve as professional surveyor-grade documentation that solicitors, mortgage lenders, and property managers accept and rely upon. Whether you are purchasing a property, managing a portfolio, or simply seeking a clear, honest record of your roof's current state, the Windsor Roof Surveys report provides that evidence.
Windsor Roof Surveys reports include all the documented evidence that insurance providers require — timestamped photography, thermal imaging, and clear damage narratives.
Common questions answered by Windsor Roof Surveys
Windsor Roof Surveys operate across the full extent of the royal borough and its surrounding areas. Our regular inspection territory covers Windsor town centre — including the streets around the Castle, the High Street, and Peascod Street — the residential neighbourhoods of Clewer Village and Clewer New Town, the interwar and post-war housing of Dedworth, the village of Old Windsor to the south, and the riverside properties along the Thames towards Datchet and Eton. We also attend homes along the Maidenhead Road corridor and in the lanes towards Winkfield and Cranbourne.
On-site inspection time depends on the property type and roof complexity. The Georgian townhouses in the town centre, with their concealed parapet gutters, multiple chimney stacks, and sometimes intricate valley arrangements, typically require two to three hours. A standard 1930s semi in Dedworth might take ninety minutes to two hours. Post-war terraces in Clewer New Town are generally assessed within ninety minutes. Every Windsor client receives their complete written report within forty-eight hours of the site visit.
Listed and heritage properties make up a notable proportion of our Windsor workload. The town sits within an extensive conservation area and contains a particularly high density of Grade I and Grade II listed buildings. Our drone-based inspection methodology is ideally suited to these structures — it delivers detailed imagery of every roof surface without placing scaffolding against fragile masonry or positioning ladders on historic stonework. We regularly survey Georgian townhouses, medieval timber-framed buildings, Victorian villas, and converted historic commercial premises across Windsor.
Insurance documentation is a core strength of our reporting format. Every comprehensive and premium Windsor Roof Surveys report includes timestamped drone photography, thermal scan evidence where applicable, clear narratives that separate storm damage from pre-existing deterioration, and itemised repair costings based on current trade rates. We have supported numerous successful claims for Windsor properties — including several that were initially rejected and subsequently overturned on the strength of our independent evidence.
The Thames creates a microclimate across Windsor that affects roofing materials in specific ways. Elevated humidity and persistent morning river mist promote aggressive moss and lichen colonisation, particularly on north-facing slopes. On the Georgian and Victorian properties in the town centre, we frequently find degraded lead flashings, eroded lime mortar, and displaced natural slates. The interwar housing across Dedworth commonly shows cracked clay tiles, failed bay window lead work, and softened timber fascias. Concrete tile fatigue and ridge mortar crumbling are widespread across the 1950s and 1960s estates in Clewer New Town.
Commercial roof inspections are a growing part of the Windsor Roof Surveys schedule. We inspect retail and hospitality premises along Peascod Street and the High Street, office conversions in the conservation area, hotel and guest house buildings, school premises, and the range of commercial properties scattered across the wider borough. Our scope covers all flat roof systems — felt, GRP, EPDM, and single-ply membrane — alongside the pitched coverings found on many of Windsor's converted period commercial buildings.

What makes Windsor's housing stock unique — and why specialist roof knowledge matters
Windsor has been shaped by its relationship with the Crown for nearly a thousand years, and that history is written into the fabric of the town's buildings. The oldest structures cluster around the Castle and the streets that served it — medieval timber-framed properties, some with handmade peg tile roofs that have been repaired and relaid across centuries. The Georgian era brought the elegant brick townhouses along Park Street, Sheet Street, and the High Street, many with parapeted rooflines, concealed lead-lined gutters, and chimney stacks that require lime mortar maintenance rather than modern cement.
The arrival of the Great Western Railway in 1849 triggered Victorian expansion, particularly through Clewer Village and along the roads south towards Old Windsor. These streets are characterised by Welsh slate roofs, ornate clay ridge tiles, decorative bargeboards, and the tall chimney stacks that give the Victorian streetscape its distinctive silhouette. Many of these properties are now over a hundred and forty years old, and while the original Welsh slate often remains in serviceable condition, the supporting lead flashings, timber fascias, and mortar bedding have frequently reached the end of their working lives.
The twentieth century added further layers to Windsor's housing stock. Edwardian villa developments along the Maidenhead Road corridor brought handsome detached homes with clay tile roofs and deep eaves. The interwar period saw Dedworth develop as a suburban district of 1920s and 1930s semis with plain clay tiles, bay window projections, and the characteristic hipped rooflines of the era. After the war, Clewer New Town and surrounding estates were built with concrete interlocking tiles and flat-roofed extensions — materials now approaching or exceeding their expected service life.
Windsor Roof Surveys provide professional roof inspections across the royal borough and beyond
The historic core around the Castle, the High Street, and Peascod Street contains a rich mixture of Georgian townhouses, Victorian commercial conversions, listed buildings, and medieval structures. Handmade peg tiles, lead parapet gutters, lime mortar ridging, and ornate chimney stacks define the town centre roofscape.
Clewer Village retains its Victorian character with detached and semi-detached villas featuring Welsh slate coverings and decorative ridge work. Neighbouring Clewer New Town, built largely in the 1950s and 1960s, presents concrete interlocking tiles and flat-roofed rear extensions now nearing the end of their serviceable life.
Dedworth developed primarily between the wars and contains a substantial stock of 1920s and 1930s semi-detached houses. Clay tile roofing on steep pitches, bay window lead work, hipped rooflines, and original chimney stacks are characteristic of the area. Ridge mortar deterioration and tile fatigue are common concerns.
The village of Old Windsor to the south of the town contains a mix of period cottages, Edwardian houses, and riverside properties. Proximity to the Thames increases humidity exposure, and the older buildings carry a variety of traditional roofing materials including handmade tiles, natural slate, and lead detailing.
The properties along the Thames and bordering Windsor Great Park include some of the borough's most substantial homes. Large detached houses with complex multi-pitch rooflines, deep valleys, extensive lead work, and multiple chimney stacks require particularly thorough aerial inspection to assess comprehensively.
Windsor Roof Surveys deliver the independent, expert roof inspections that this historic royal borough demands. Whether you are purchasing a Georgian townhouse in the conservation area, battling recurring damp in a Dedworth semi, navigating an insurance claim after storm damage, protecting a listed property in Clewer Village, or simply seeking honest clarity on the condition of an ageing roof before committing to costly repairs, our surveys provide the documented evidence and professional analysis you need to act with confidence.
Every inspection pairs certified expertise with advanced technology — drone aerial photography, thermal imaging, and comprehensive written reporting — giving you a complete, unbiased picture of your roof's condition. Windsor Roof Surveys do not carry out repairs. We do not recommend contractors. We provide the facts, the photographs, and the costings, and you make the decisions.
Every report from Windsor Roof Surveys is independent, detailed, and structured to be acted upon — whether you are buying, selling, claiming, or simply protecting your property.
