Property Restoration Services London Ltd are roofers in Marylebone W1, carrying out roof repairs, slate and tile roofing and mansard conversions on the Georgian terraces around Harley Street, Wimpole Street and Portman Square. We are based on Chiswick High Road and cover W1 alongside the rest of Central and West London, including the parapet fronted roofs and conservation area matching rules that apply across the Harley Street and Portman Estate conservation areas. Most Marylebone enquiries are seen within two working days, with emergency callout available for storm damage and active leaks affecting homes, consulting rooms and shops alike.
Marylebone's core was built up between the 1720s and 1820s under the Portman Estate and the Howard de Walden Estate, producing the long stuccoed and brick Georgian terraces that still line Harley Street, Wimpole Street and Devonshire Place. These streets sit within the Harley Street Conservation Area and the Portman Estate Conservation Area, so their parapet fronted roofs read as one continuous roofline from street level, and a mansard loft conversion is normally the accepted way to add space because it can be designed to sit within that roofscape rather than change it. A large share of these townhouses were converted decades ago from single family homes into private medical consulting rooms, so the roof now sits above waiting rooms and treatment rooms rather than bedrooms, which changes how a leak needs to be handled.
Behind the grand facades, Marylebone still has a working mews layer. Streets such as Wimpole Mews and Devonshire Mews were built as coach houses and stable blocks serving the townhouses in front, later converted into mews houses with lower, simpler roofs and much tighter street access than the terrace behind them. Around Marylebone High Street the mix changes again into a village style parade of independent shops, delis and cafes with mansion flats above, most with a flat roofed rear addition over the kitchen or stockroom extension. Grander mansion blocks around Portman Square and Manchester Square add a third roof type into the picture, pitched slate roofs shared across a single freehold and several flats, which raises different questions about who is responsible for a repair.
From slate repairs on Georgian terraces along Harley Street to flat roofing on the mews houses around Wimpole Mews, we cover the full range of roofing work typical of Marylebone. Every job starts with an on site assessment before any quote is given.
Repair of slipped slate and cracked ridge tiles on the Georgian terraces along Harley Street and Wimpole Street, matched to satisfy conservation area requirements.
New roof coverings and mansard style loft conversions designed to sit within the existing roofline, the usual route to extra space in Marylebone's conservation areas.
GRP and modern flat roofing for the mews houses around Wimpole Mews and Devonshire Mews, and for rear extensions along Marylebone High Street.
Clearance and repair of the parapet gutters hidden behind Marylebone's Georgian facades, a common source of damp in the stucco below when an outlet blocks.
Repointing and flashing renewal for the multiple flue chimney stacks typical of Marylebone's Georgian terraces, several built to serve individual rooms.
Emergency callout for storm damage and active leaks, arranged where needed around the opening hours of Harley Street practices and Marylebone High Street shops.
Slate and tile roofing is the service we carry out most often in Marylebone, since the dominant property type across Harley Street, Wimpole Street and the streets around Portman Square is the Georgian terrace with a parapet fronted, mansard topped roof concealed behind the facade. Within the Harley Street Conservation Area and the Portman Estate Conservation Area, Westminster City Council expects any re-roofing or mansard conversion to match the existing slate type, valley detail and pitch, so the roofline still reads as one continuous terrace from street level rather than a patchwork of different repairs.
A large share of these townhouses now operate as medical consulting rooms along Harley Street and Wimpole Street, so a repair sits above a waiting room or treatment room rather than a bedroom, and we plan access and noise around clinic hours where we can. Where a mansard loft conversion is being added, we work to the same slate and dormer detailing as the rest of the terrace so the new floor does not stand out from the street or draw an objection from the conservation area officer.
The process is the same whether the job is a single slipped slate or a full mansard re-roof, so you know what to expect before we arrive.

Yes. Harley Street and Wimpole Street carry one of London's largest concentrations of private medical consulting rooms, most operating from converted Georgian townhouses, and Marylebone High Street runs a parade of independent shops, delis and galleries below mansion flats. We carry out roof repair and flat roof replacement for both, scheduling work around clinic opening hours and patient appointments on Harley Street, and around trading hours on the High Street, with a written scope of work for landlords, managing agents or practice managers who need sign off before work begins.

Property Restoration Services London Ltd covers Marylebone and the full W1 postcode, along with neighbouring Mayfair, Soho, Bayswater and Paddington across Central and West London. We aim to carry out an on site assessment within two working days for standard repairs, and offer emergency callout for storm damage and active leaks affecting Harley Street practices, Marylebone High Street shops or private homes. Every W1 postcode is covered, including the terraces around Harley Street and Wimpole Street, the shops along Marylebone High Street, and the mansion blocks around Portman Square and Manchester Square. Many of our Marylebone jobs involve matching slate and mansard detailing to satisfy the Harley Street and Portman Estate conservation areas, so we check the full roofline rather than treating a repair as an isolated patch. Quotes are provided after an on site assessment, with no call out charge for the initial visit anywhere within our W1 coverage area.
Alongside Marylebone we cover the following areas, with dedicated pages for those already live on our site.
The questions below cover what Marylebone customers ask us most often.
We aim to carry out an on site assessment within two working days for standard repairs across Marylebone and the rest of W1. For storm damage or an active leak we offer emergency callout and try to attend the same day, since a leak above a Harley Street consulting room or a Marylebone High Street shop can disrupt a business as much as it damages the building. Response times can vary slightly during periods of severe weather when demand rises across Central London, but Marylebone is a core part of our coverage area alongside Mayfair and Soho, and is not treated as a lower priority than streets closer to our Chiswick High Road base. Once we have inspected the roof we confirm a schedule for any follow up work, so you know when the job will be completed rather than waiting on an open ended timeframe.
We cover every street in Marylebone and the full W1 postcode area, from the Georgian terraces around Harley Street and Wimpole Street to the shops and mews properties around Marylebone High Street and Portman Square. We also cover the neighbouring areas of Mayfair, Soho, Bayswater and Paddington, so a job that sits near a postcode boundary is not a problem. Coverage includes residential roofing, such as slate repair and mansard conversion work on Georgian townhouses, and commercial roofing for Harley Street consulting rooms and Marylebone High Street shops. Our engineers are based on Chiswick High Road and travel out to W1 for every job, we do not subcontract Marylebone work to a third party roofer working under our name. If you are unsure whether your street falls inside our standard coverage area, call us and we can confirm before booking an inspection.
All quotes are provided following an initial assessment of the work required, we do not quote over the phone without seeing the roof first. Costs depend on the extent of the damage, the materials involved and how accessible the roof is, and a mansard or parapet repair on a Marylebone Georgian terrace can look very different once we are actually up there compared with what is visible from the street. Contact us for a free, no obligation inspection and a clear written quote before any work begins. For larger jobs, such as a mansard conversion or a full re-roof requiring conservation area matching, we provide a written scope of work you can share with a managing agent, freeholder or practice manager if needed, so there is a clear record of what has been agreed before work starts on site.
We carry out a free, no obligation inspection before providing a quote. All quotes are provided following an initial assessment of the work required, we do not quote without seeing the roof first, since a parapet gutter problem behind a Georgian facade can look very different once we are actually up there. Once you accept the quote we schedule the work and confirm a date. There is no call out charge for the initial inspection visit anywhere within W1, whether the job turns out to be a small slate repair or a larger mansard conversion. We aim to give you a realistic idea of timing at the point of quoting, rather than leaving you to chase for a start date afterward, and the same process applies whether the work is a single repair or a full re-roof on one of Marylebone's Georgian terraces.
Once you accept a quote we agree a date and confirm what access is needed, whether that is a ladder, a tower or scaffolding depending on the roof and the width of the street. Our engineer carries out the agreed work, matching slate, valley lead or mansard detailing to the existing roof covering where the job is a repair rather than a full replacement, as expected within the Harley Street and Portman Estate conservation areas. On parapet gutter work we check the full run for other weak points as standard, since this is the most common failure pattern we see across Marylebone's Georgian terraces. Once the work is finished you receive a written summary of what was done, along with any maintenance advice. If anything is found during the job that was not visible during the original inspection, we discuss it with you before proceeding rather than carrying out extra work without agreement.
The most common issues are blocked parapet gutters and hoppers behind the stucco facades of Marylebone's Georgian terraces, slipped slate and worn valley lead on mansard sections after wind, and multiple flue chimney stacks needing repointing on the older townhouses. Because these terraces conceal their roofs behind a parapet, a blocked outlet can cause internal damp before it is visible from the street. We also see ageing flat roofs over rear kitchen extensions on Marylebone High Street shops and mews houses reaching the end of their working life, and lead flashing wear where a mansard conversion meets the original roofline, which is a routine call out for us given how many Marylebone terraces have had a loft conversion added. Mansion blocks around Portman Square and Manchester Square raise a different pattern again, around shared roof responsibility rather than the roof covering itself.
We regularly work on the Georgian terraces around Harley Street and Wimpole Street, and on the mews houses around Wimpole Mews and Devonshire Mews. The concealed parapet roofs on these terraces mean more lead flashing junctions and hidden gutters to maintain compared with a standard terrace elsewhere in London, which is why blocked outlets and slipped slate come up often here. Marylebone High Street itself generates a steady amount of flat roof repair work on the shops below the mansion flats, often needing to be scheduled around trading hours. Mansion blocks around Portman Square and Manchester Square bring a different type of enquiry, more often about shared roof responsibility than the roof covering itself. We check the full roof on every visit regardless of which street the job is on, rather than assuming a lighter inspection is enough away from Harley Street.
Most like for like repairs do not require planning permission. Marylebone sits within the Harley Street Conservation Area and the Portman Estate Conservation Area, and Westminster City Council applies strict controls to any work that changes the roofline or appearance of a Georgian terrace from the street, including many mansard loft conversions. We flag anything that may need consent during the inspection so you can check with Westminster City Council before proceeding, rather than assuming a straightforward repair and finding out otherwise partway through the job. This is worth confirming early on any mansard conversion project too, since a new roofline is treated differently from a like for like slate replacement. We would rather flag a possible consent question during the initial inspection than have it surface once work is already underway.
Yes. We carry out roof condition inspections for buyers ahead of a purchase, and for tenants or practice managers taking on a Harley Street consulting room or a Marylebone High Street shop who want to know the condition of the roof before signing a lease. The survey covers slate condition, flashing, parapet gutters and any signs of water ingress, with a written report provided afterward. This is a common request in Marylebone given how many of the area's Georgian terraces have already had a mansard conversion added, and how many commercial tenants want documented roof condition before committing to a lease. A written report is useful evidence for a buyer negotiating on a property, or for a practice manager planning a fit out, and it gives a clear picture of the roof's condition before any commitment is made.
This depends on the specific property and its lease or title deeds, and can vary on Marylebone's mansion blocks and converted townhouses where a single roof serves several flats or consulting rooms under one freehold. In many cases responsibility sits with the freeholder or the managing agent acting for the building, and costs may be shared between leaseholders under the terms of the lease, but arrangements vary from building to building and are not something we can confirm without seeing the paperwork. We identify where the fault lies during our inspection, which is often useful evidence if a conversation with a managing agent or freeholder is needed, but we recommend checking your lease or speaking to your managing agent directly to confirm responsibility before work on a shared roof proceeds.
A recurring leak usually means the original repair addressed the visible symptom rather than the underlying cause, commonly a blocked section of parapet gutter further along the run, or a second failure point in the lead flashing that was not inspected the first time. On Marylebone's Georgian terraces this is often a hidden gutter that was patched at the exact spot water was seen coming through, without checking the full length of the run behind the parapet. We check the full length of any shared gutter and surrounding flashing during a repair, not only the exact spot where a stain appeared inside, since a concealed parapet gutter can have more than one weak point along its run. Checking the whole run once, rather than returning for a second visit after a repeat call out, is the approach we take as standard.
Many repairs on Marylebone's properties can be carried out using a tower or ladder access, particularly for isolated slate replacement or gutter clearance. Larger jobs, such as a full parapet gutter renewal or a mansard conversion on the taller Georgian terraces, may need scaffolding for safe access, especially where a parapet limits how much can be reached from a ladder. Mews streets such as Wimpole Mews and Devonshire Mews are narrow, so we plan smaller access equipment and confirm parking and loading restrictions with Westminster City Council in advance where scaffolding cannot fit. We confirm the access method needed during the inspection so you know what to expect before work is scheduled, and we plan any scaffolding to minimise how long it is up outside your property or practice.
Yes, this is something we plan for as standard on Harley Street and Wimpole Street work. Where a roof sits above an active consulting room, we agree access times with the practice manager in advance, aiming to carry out noisier work such as slate replacement or scaffolding installation outside clinic hours where the schedule allows. For an active leak affecting a treatment room we prioritise a same day response regardless of the time of day, since water ingress above clinical space needs addressing quickly. We provide a written scope of work that a practice manager or landlord can review and approve before work begins, and we keep noise and disruption to a minimum during any hours when the practice is seeing patients.
