GRADE II LISTED SLATING & MANSARD RESTORATIONS IN BELGRAVIA
Thomas Cubitt’s grand white-stucco terraces framing Eaton Square, Chester Square, and Belgrave Square (SW1X and SW1W), alongside secluded cobbled mews houses along Kinnerton Street and Wilton Row, demand exacting heritage roof craftsmanship. Behind tall classical balustrades and stucco cornices sit steeply pitched slate mansards, timber sash dormers, and deep lead-lined box gutters. When century-old iron nails corrode or thermal movement splits aged leadwork, rainwater tracks down party walls into principal reception rooms. Acting as an NFRC-accredited roofer in Belgravia, London Roofing Specialist deploys directly employed slaters, leadsmiths, and roof carpenters to execute conservation-grade roof renewals.
Treated Timber Battens, Dormer Framing & Grosvenor Estate Standards
Stripping a five-storey Belgravia residence or mews conversion begins with a thorough structural appraisal of the exposed C24 timber rafters, collar ties, and dormer cheeks. As shown in our SW1 project photography, we replace decayed woodwork, dress a high-tensile vapour-permeable membrane across the rafters, and fix graded BS 5534 treated timber battens ready for hand-holing and copper-nailing prime natural slates in full accordance with Westminster City Council and Grosvenor Estate conservation requirements.

Frequently Asked Questions: Roofer Belgravia SW1X & SW1W
Do you comply with Grosvenor Estate and Westminster Conservation Area roofing rules?
Yes. Nearly all residences across Belgravia sit within the Belgravia Conservation Area and are subject to strict Grosvenor Estate management covenants or Grade II listed building controls. We supply authentic natural Welsh slate samples, specify traditional rolled lead thicknesses to Lead Sheet Training Academy (LSTA) codes, and prepare full photographic condition reports to assist with heritage sign-off.
Why do hidden parapet gutters on Belgravia townhouses leak so frequently?
Stucco-fronted terraces in SW1 channel all roof rainwater into concealed box gutters behind the front and rear parapet walls. Over decades, oversized lead bays split under summer heat expansion, or autumn leaves block the outlets and force water over the upstands. We strip the perished trough, re-profile the timber sole board to improve the drainage fall, and install correctly bayed Code 6 or Code 7 lead linings with high-capacity overflows.
