Roofers in Kensington, W8

Yes, GMG Roof Experts run a 24 hour emergency roof repair service covering Kensington, South Kensington, Holland Park and the surrounding area. We run priority same-day cover, with the exact arrival time depending on central London traffic from our west London base. The most common Kensington emergency is a leak from a failed parapet or valley gutter showing up as staining to a top-floor ceiling. Our first visit focuses on stopping further water ingress, with the permanent repair agreed and scheduled once the roof is secure.

We offer roof repairs, parapet and valley gutter relining, traditional leadwork, natural slate repair and re-slating, mansard roof repairs, full roof replacements, emergency call-outs, chimney and party wall stack repairs, flat roofing in lead, asphalt, EPDM and GRP, roof terrace waterproofing, guttering, and roof inspections and surveys for blocks. We work on stucco terraces, red-brick mansion blocks and mansard conversions across the W8, SW7 and W14 postcode districts, for homeowners, freeholders and managing agents.

We visit the property, get onto the roof behind the parapet where possible, and put together a written quote covering materials, labour, access and timescale. All pricing is provided on request following that assessment, since valley gutter length, lead code, slate type, access and any borough licences all affect the scope of work. For a flat or a block we also confirm ownership of the roof and any freeholder or managing agent sign-off needed. You will have a clear written quote before any work is agreed.

A localised repair, such as replacing slipped slates or sealing a small lead split, usually takes half a day to a full day once access is in place. A parapet or valley gutter reline typically takes two to four days depending on length and access. Mansard and dormer repairs, or a full re-slate on a terrace, generally run one to two weeks, with the timescale driven as much by scaffold and licensing as by the roof itself. Your written quote will include a specific timescale for your property.

Because the roof is hidden. Most Kensington terraces have an M-shaped roof behind the parapet that drains to a concealed lead-lined valley gutter and internal rainwater pipes. A split in that lead, a blocked outlet, or a lap that has opened up lets water in at roof level, and it then tracks along timbers and down the party wall before it shows as a stain on a ceiling, often a room or two away from the actual fault. Finding the cause means inspecting the full valley, the upstands and the outlets, not just the spot where the damp appears.

The earliest terraces, around Kensington Square and the streets off Kensington Church Street, tend to have parapet and valley lead that is well past its working life. The grand stucco terraces around Cornwall Gardens and Queen's Gate show valley and cornice leaks as top-floor ceiling staining. Mansion blocks around Kensington Court and Iverna Gardens have communal flat roofs and shared outlets that need coordinated repair, and the mansard conversions around Phillimore Gardens and Campden Hill Road have extra dormer and valley junctions to maintain. Every property type has different risk points.

Yes. A large part of our Kensington work is communal roofs for freeholders, managing agents and residents' associations. We survey the whole roof, valley gutters and stacks, set out a prioritised programme of works with clear scope, and provide the detail needed for a Section 20 consultation under the Landlord and Tenant Act 1985 where the cost of major works will be recharged to leaseholders. We coordinate access around porters, tenants and the managing agent.

On a freehold house, the owner is responsible for their own roof, but a shared chimney stack or a roof junction on the party wall is covered by the Party Wall etc. Act 1996, and work on it usually needs notice to the adjoining owner. In a leasehold flat or a mansion block, the main roof is almost always the freeholder's responsibility, maintained through the service charge, even where a top-floor flat feels the leak first. We identify which applies during our inspection and advise on the process before any work on a shared element begins.

Yes. Most Kensington streets have no rear vehicle access, controlled parking and, on the main roads, red routes, so a roof job usually needs a scaffold or hoist licence and often a suspended parking bay from the Royal Borough of Kensington and Chelsea or Transport for London. We include the licensing and access plan in the quote and arrange the permits as part of the job rather than leaving it to the client.

Yes. Many repairs, including localised slate work, flashing repairs and short sections of valley gutter, can be done from a tower or a roof access system without full scaffolding, which keeps time on site and street impact down. Larger valley reline or re-slate work does need scaffolding, but we programme it around the building's use, agree access windows with residents or the managing agent, and keep the working area contained.

Yes, most of our Kensington work is on properties inside one of the Royal Borough's conservation areas, and many are listed. We match natural slate, use lead of the correct code dressed traditionally, and keep the parapet, cornice and coping detail as found. Where the work goes beyond a like-for-like repair we advise on whether it is likely to need conservation area or listed building consent before anything starts.

Most like-for-like repairs using matching materials do not need permission, but adding or altering a mansard, changing the roof line, or adding a roof terrace or rooflights generally needs planning permission from the Royal Borough of Kensington and Chelsea, and any more than a straightforward repair to a listed building needs listed building consent. We flag anything in your case that looks like it may need council sign-off during our inspection, though the final determination always sits with the borough.
