MANSARD SLATING & DORMER LEADWORK ACROSS W11 & W14
Stucco-fronted Italianate villas lining Ilchester Place, tree-shaded Victorian residences along Addison Road, and Arts and Crafts studio houses across the Melbury Road and Abbotsbury Road estates feature some of West London’s most intricate rooflines. Steep mansard pitches, projecting timber dormers, and deep parapet troughs rely on sound natural slates and heavy milled lead to keep driving rain out of top-floor rooms. When nineteenth-century iron nails rust through—causing slates to slide—or weathered lead sills split beneath sash windows, water penetrates straight into ornamental plasterwork. Operating from nearby Kensington High Street as an NFRC-accredited roofer in Holland Park, London Roofing Specialist delivers sympathetic pitched roof restorations using directly employed slaters and leadsmiths.
Roof Carpentry Inspections, Vapour-Permeable Underlays & Battens
Before re-slating or re-tiling any W11 or W14 residence, our surveyor examines the internal roof void to check C24 rafters, hip timbers, and dormer cheeks for wet rot or structural movement. We strip degraded underfelt, dress a high-tensile breathable membrane across the rafters, and fix graded BS 5534 pressure-treated battens that hold every slate course firm against high wind uplift.
CONSERVATION SLATE, ROLLED LEAD & LOFT AIRFLOW IN HOLLAND PARK
Properties within the Holland Park Conservation Area require traditional roofing materials that satisfy Royal Borough of Kensington and Chelsea (RBKC) heritage officers while meeting modern Part L thermal standards.
Natural Welsh & Spanish Slating
Hand-dressed, copper-nailed natural slates matched in riven texture, blue-grey hue, and headlap gauge for listed W11 and W14 roofs.
Code 5 & Code 6 Rolled Lead Flashings
Bossing and lead welding of dormer window aprons, secret cheek soakers, stepped chimney gutters, and deep parapet box troughs.
Passive Roof Ventilation & Thermal Insulation
Concealed eaves-to-ridge airflow pathways and inline slate vents paired with rigid PIR loft insulation to eradicate winter condensation.
Handmade Clay Tiling & Mechanical Dry Ridges
Double-lapped clay plain tiles, decorative ridge finials, and storm-proof stainless steel dry-fix ridge systems that never crack or wash out.
Weatherproofing Timber Dormer Windows & Crown Junctions
As shown in our Holland Park rooftop photography, timber sash dormers set into pitched slate mansards leak rapidly when old mortar fillets crumble or thin flashing strips tear. Our craftsmen boss one-piece Code 5 lead aprons beneath the window sill and interleave secret lead soakers up each course of the dormer cheek, shedding rainwater cleanly onto the main slate slope.
CHIMNEY RESTORATIONS, VALLEY GUTTERS & 10-YEAR GUARANTEES
Mature plane and oak trees surrounding Holland Park shed heavy autumn leaf fall into hidden lead box gutters and valley troughs, causing trapped rainwater to back up beneath the slate eaves. Alongside full pitched roof renewals around Lansdowne Walk, Clarendon Road, and Holland Park Avenue, we clear and reline fatigued lead valleys in welded Code 6 lead, repoint tall brick chimney stacks in breathable lime mortar, and fit low-profile conservation skylights. Every complete re-roof and leadwork overhaul we execute in W11 and W14 carries a 10-year insurance-backed workmanship guarantee and full public liability insurance.

Frequently Asked Questions: Roofer Holland Park W11 & W14
Why is rainwater coming in beneath my dormer sash window during heavy wind?
Dormer leaks on Holland Park mansard roofs typically happen when the lead apron under the wooden sill perishes or when wind-driven rain blows sideways past undersized cheek flashings. We strip the surrounding slates, check the timber sill and corner posts for rot, and dress a new hand-bossed Code 5 lead apron and secret side soakers into the junction.
Do I need RBKC conservation consent to re-slate a house in Holland Park?
Replacing tired slates and lead flashings on a like-for-like basis using matching natural slate and rolled lead generally falls under permitted development. Where a property on the Phillimore or Ilchester Estates is Grade II listed or subject to an RBKC Article 4 Direction, we provide natural slate samples and heritage specification sheets to secure conservation sign-off before scaffolding goes up.
