IKO ARMOURPLAN & SKYLIGHT UPGRADES ON PORTOBELLO ROAD W11
Across Notting Hill (W11) and Ladbroke Grove (W10), from stucco-fronted Victorian townhouses around Pembridge Square and Lansdowne Crescent to mixed-use commercial premises along Portobello Road and Westbourne Grove, flat roofs protect high-level crown decks, rear extensions, and commercial workspaces. On our recent Portobello Road project, London Roofing Specialist acted as the principal flat roofer in Notting Hill, stripping the perished roof build-up to deliver a structurally reinforced warm roof fully signed off by Royal Borough of Kensington and Chelsea Building Control.
Five Structural Roof Openings, Electric Velux Skylights & Access Hatches
A central requirement of this W11 refurbishment involved precision carpentry to cut and trim five structural openings into the timber deck. Our team framed insulated upstand kerbs to house four automated electric Velux skylights alongside a heavy-duty polycarbonate roof access hatch, flooding the interior with natural daylight while providing safe, compliant rooftop maintenance access.
ACCREDITED FLAT ROOFER IN NOTTING HILL W11 & W10
To weatherproof the new deck and five skylight upstands on Portobello Road, our NFRC-accredited installers fitted a mechanically fixed, hot-air welded IKO Armourplan single-ply membrane. Engineered for high UV resistance and foot traffic, this installation was certified upon completion with a 20-year single-point guarantee.
IKO Armourplan & Sika Sarnafil Single-Ply
Polyester-reinforced thermoplastic membranes with heat-welded seams that remain permanently flexible and impervious to standing water.
Electric Skylights & Polycarbonate Access Hatches
Structural rafter trimming, 150mm insulated timber kerbs, and welded membrane collars for automated rooflights and opening roof hatches.
Cold-Applied Liquid Polyurethanes & GRP
Flame-free elastomeric resins brushed around intricate stucco parapet walls, cast-iron soil stacks, and butterfly gutter troughs.
Part L Warm Roof Thermal Insulation
High-density rigid PIR insulation boards installed over a continuous vapour control layer to prevent condensation and cut heating costs.
Flame-Free Hot-Air Welding for Historic W11 Properties
We never use naked bitumen gas torches on historic Notting Hill timber decks or near listed stucco facades. Fusing IKO Armourplan and Sika membranes with temperature-controlled hot-air welding machines eliminates fire risks during construction while forming a seam stronger than the membrane itself.
PARAPET DRAINAGE, BUILDING CONTROL & 20-YEAR GUARANTEES
As shown in our Notting Hill rooftop photography, flat roofs enclosed by brick and rendered parapet walls rely on accurate falls to prevent rainwater pooling around skylight kerbs. Our carpenters install graduated timber firrings beneath 18mm marine plywood decking so water clears rapidly into perimeter outlets and hoppers. Every full flat roof replacement we complete in W11 is carried out by our own vetted, directly employed technicians and backed by insurance-backed guarantees alongside 20-year manufacturer warranties.

Frequently Asked Questions: Flat Roofer Notting Hill W11
Can you cut new openings for electric skylights or an access hatch into an existing flat roof?
Yes. When stripping your old flat roof covering down to the joists, our roof carpenters double up the structural C24 trimming rafters to form safe, load-bearing apertures for electric Velux rooflights, walk-on glass panels, or hinged polycarbonate access hatches, handling all Part A and Part L Building Control sign-offs.
Why choose IKO Armourplan single-ply over traditional torch-on felt in Notting Hill?
Traditional mineral felt absorbs solar heat, blisters within 10 to 15 years, and requires naked flames during installation. Light grey IKO Armourplan reflects summer heat away from top-floor W11 flats and commercial spaces, is welded without naked flames, and carries a 20-year manufacturer warranty with a service life exceeding 35 years.
