Frequently Asked Questions About Roofing in Hammersmith
Content last reviewed: September 2026.
The questions below cover what Hammersmith customers ask us most often.
How quickly can you attend a roofing job in Hammersmith?
Quickly. Our yard is on Chiswick High Road, a few minutes from the W6 border, so Hammersmith is one of the areas we reach fastest. We aim to carry out an on site assessment within two working days for standard repairs, and for storm damage or an active leak we offer emergency callout and try to attend the same day. Once we have inspected the roof we confirm a schedule for any follow up work, so you know when it will be finished rather than waiting on an open ended timeframe.
Which parts of Hammersmith and W6 do you cover?
We cover every street in Hammersmith and the full W6 postcode, from the stucco terraces of Brackenbury Village and Brook Green to the villas around St Peter's Square and Ravenscourt Park, the mansion blocks on Hammersmith Grove, and the listed houses on Upper Mall, Lower Mall and Hammersmith Terrace by the river. We also cover Chiswick, Acton, Ealing and Shepherd's Bush from the same yard. Our roofers travel out to W6 for every job, we do not subcontract Hammersmith work to a third party roofer working under our name.
Why is my Hammersmith roof leaking when the slates look fine?
On a Hammersmith terrace the leak is more often behind the parapet than in the slates. The usual causes are a cracked stucco coping on top of the parapet wall, a rendered cornice that has separated from the brickwork, a split lining in the concealed valley gutter, or a failed lead flashing where the roof meets a chimney or a wall. Water gets in at one of those points and tracks along the timbers before it shows on a ceiling, often in a different room. This is why we inspect the coping, cornice, valley and flashings, not just the visible roof slope, before quoting.
How much do roof repairs cost in Hammersmith?
As a general guide, minor repairs such as a slipped slate or single ridge tile typically run £150 to £350, emergency temporary weatherproofing from £200, stucco coping and parapet crack repair £400 to £1,200 or more per elevation, and a concealed valley or parapet gutter re-line £650 to £1,800 or more per run before scaffolding. Flat roof or chimney repairs run £400 to £1,500 or more, and a full pitched roof replacement around £260 to £290 per square metre plus scaffolding. See our cost guide table above. Your exact price is confirmed after an on site assessment, and we do not quote over the phone for parapet or lead work because access and the extent of the repair change the figure once we are up there.
Do you work on listed buildings and in Hammersmith's conservation areas?
Yes. A large part of W6 is covered by a conservation area, including St Peter's Square, the Hammersmith Mall area taking in Upper and Lower Mall and Hammersmith Terrace, Brackenbury and Ravenscourt. Many of the riverside houses are individually listed. On those properties we work to like-for-like repair, using reclaimed or matched natural slate, lead dressed to the correct code, and lime mortar where the original used it. Where a change needs listed building consent or conservation area consent, we prepare the scope and drawings so it can go to the London Borough of Hammersmith & Fulham before work starts, and we are used to working alongside a conservation officer or heritage surveyor.
How does your quoting process work?
We carry out a free, no obligation inspection before providing a quote, which on a Hammersmith terrace means getting up to look behind the parapet, along the concealed valley and at the coping and flashings, not assessing it from the ground. 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 W6, whether the job turns out to be a single slipped slate or a full parapet gutter re-line. We give you a realistic idea of timing at the point of quoting rather than leaving you to chase for a start date.
What happens once I book a roofing job in Hammersmith?
Once you accept a quote we agree a date and confirm what access is needed. On W6's terraced streets that often means a scaffold with a licence and a parking dispensation from LB Hammersmith & Fulham, which we arrange before we start. Our roofer carries out the agreed work, matching slate, lead and mortar to the existing roof where the job is a repair. On parapet and valley work we check the full run and both outlets for other weak points as standard. Once finished you receive a written summary of what was done and any maintenance advice.
Do you repair stucco copings and rendered cornices as well as the roof?
Yes, and on a Hammersmith parapet the two usually need doing together. If we re-line a concealed valley gutter but leave a cracked coping or a separated cornice above it, water will keep getting in behind the parapet and the roof repair will not solve the leak. We rake out and re-form coping and cornice cracks in a matching mortar or a flexible repair system as part of the parapet job, so the whole assembly is watertight rather than just the gutter.
Do you remove spray foam roof insulation in Hammersmith?
Yes. A lot of W6 terraces have had a loft conversion with sprayed foam applied to the sloping ceiling or the underside of the slates, and it now commonly holds up a sale or a remortgage because lenders and RICS surveyors treat it as a defect. We remove open-cell and closed-cell foam by hand, take back any bonded felt and battens, and leave the roof space open for a surveyor to inspect, with a written record for the lender. If the foam has gripped the underside of the slate and cannot be separated cleanly, we price a re-slate at the same time so it is one visit and one scaffold.
Do you work with managing agents and residents' management companies in Hammersmith?
Yes. Hammersmith has a lot of communal roofs, from the Victorian and Edwardian mansion blocks around Ravenscourt Park and Hammersmith Grove to converted villas across Brook Green and the newer riverside blocks at Fulham Reach. We provide a written scope and costings suitable for a Section 20 leaseholder consultation, carry out condition surveys and budget costings for reserve-fund planning, and can attend a directors' or residents' meeting. Flat roof renewal, parapet and valley gutter work and cyclical maintenance on communal roofs are all regular work for us in W6.
Do I need planning permission for roof work in Hammersmith?
Most like for like repairs do not need planning permission. Work that changes the roofline, adds rooflights or dormers to a front-facing slope, sits within a conservation area, or is on a listed building is more likely to need consent, and on a flat or maisonette you will usually also need the freeholder's permission regardless of planning. We flag anything that may need consent during the inspection so you can check with the London Borough of Hammersmith & Fulham before proceeding, rather than assuming a straightforward repair and finding out otherwise once the job has started.
Who is responsible for a shared parapet or valley gutter between two Hammersmith houses?
On W6's terraces a concealed valley or parapet gutter often runs along or across the party wall, so responsibility can be shared between both properties or sit with whichever roof it mainly drains, depending on the title deeds. Arrangements vary from house to house and are not something we can confirm without seeing the paperwork. We identify exactly where the fault lies during the inspection, which is useful if a conversation with a neighbour is needed, but we recommend checking your deeds or speaking to your neighbour first. Where the repair means cutting into or replacing a shared gutter, the Party Wall etc. Act 1996 may apply.
Can roof repairs be carried out without scaffolding in Hammersmith?
Isolated slate or ridge repairs can often be done from a roof ladder or a tower. Parapet, coping, concealed valley and leadwork jobs usually need a scaffold for safe access behind the parapet, and on W6's terraced streets that means a scaffold licence and, on the red routes near King Street and the A4, a parking dispensation from LB Hammersmith & Fulham. We arrange those before we start, plan the scaffold to be up for the shortest time possible, and check rear access and neighbour agreements where a scaffold has to bridge two properties.
Do you offer a roof survey before buying a Hammersmith property or starting a loft conversion?
Yes. We carry out roof condition inspections for buyers ahead of a purchase and for owners planning a loft conversion who need to know the state of the existing roof first. The survey covers slate and lead condition, the concealed valley and parapet gutters, the coping and cornice, the flashings and any signs of water ingress, with a written report afterward. This is a common request in Hammersmith given how many W6 terraces have already been converted and how many more conversions are planned, and a written report is useful evidence for a buyer negotiating or for an architect planning the roofing element of a conversion.
What roofing problems are most common on the Hammersmith riverside?
The riverside houses on Upper Mall, Lower Mall and Hammersmith Terrace take the full force of wind and driven rain off the Thames, so we see more wind-lifted slate, more wear to lead flats over bays and back additions, and more trouble at parapet gutters and their outlets than on the sheltered inland streets. Many of these houses are listed, so repairs are like-for-like in matched slate and dressed lead, with lime mortar where the original used it. The newer riverside blocks at Fulham Reach and Distillery Wharf have single-ply flat roofs where the recurring issue is lifted or split detailing at the parapet upstands.
