IKO ARMOURPLAN & SKYLIGHT UPGRADES ACROSS SOHO W1
Bounded by Oxford Street, Regent Street, Charing Cross Road, and Shaftesbury Avenue, Soho (W1F, W1D, and W1V) is London’s historic creative, hospitality, and film post-production heartland—where tightly packed seventeenth- and eighteenth-century Georgian townhouses around Soho Square, Golden Square, Dean Street, and Frith Street sit alongside the timber-framed retail heritage of Carnaby Street and the dense restaurant rooftops of Wardour Street, Old Compton Street, and Chinatown. Across this vibrant square mile, flat roofs protect high-level mansard crown decks, acoustic editing suites, commercial kitchen lightwell extensions, and private members’ club terraces. When old mastic asphalt fractures from constant commercial extract fan vibration and heat, or mineral felt blisters around congested plant rooms, water penetrates straight into studios, restaurants, and top-floor loft apartments. Operating as an NFRC-accredited flat roofer in Soho, London Roofing Specialist strips perished coverings back to the structural deck to deliver warm roof upgrades fully signed off by Westminster City Council Building Control.
Structural Roof Openings, Electric Velux Skylights & Access Hatches
Because deep Soho floorplans and enclosed rear lightwells off Berwick Street, Greek Street, and Lexington Street are starved of natural light, a central requirement of our W1 flat roof refurbishments involves precision carpentry to cut and trim structural openings into the timber or concrete deck. As shown in our project photography, our team frames insulated 150mm upstand kerbs to house automated electric Velux skylights alongside heavy-duty polycarbonate roof access hatches, flooding dark studio and living spaces with daylight while providing safe, compliant rooftop maintenance access for plant servicing.
ACCREDITED FLAT ROOFER IN SOHO W1F & W1D
To weatherproof exposed mansard crowns, rear commercial infill decks, and multi-skylight upstands across Soho, our NFRC-accredited installers fit mechanically fixed, hot-air welded IKO Armourplan and Sika Sarnafil single-ply membranes alongside cold-applied liquid polyurethanes. Engineered for high UV resistance, acoustic plant loads, and foot traffic, our single-ply installations carry up to a 20-year manufacturer guarantee alongside our 10-year workmanship cover.
IKO Armourplan & Sika Sarnafil Single-Ply
Polyester-reinforced thermoplastic membranes with heat-welded seams that remain permanently flexible and impervious to standing water and urban pollutants.
Electric Skylights & Polycarbonate Access Hatches
Structural rafter trimming, 150mm insulated timber kerbs, and welded membrane collars for automated rooflights, studio northlights, and opening plant hatches.
Cold-Applied Liquid Polyurethanes & Plant Detailing
Odour-controlled, flame-free elastomeric resins brushed around commercial kitchen flues, acoustic chiller plinths, cast-iron soil stacks, and narrow brick parapet gutters.
Part L Warm Roof Thermal & Acoustic Insulation
High-density rigid PIR insulation boards installed over a continuous vapour control layer to prevent winter condensation, reduce street noise, and cut air-conditioning and heating costs.
Flame-Free Hot-Air Welding for Historic W1 Properties
We never use naked bitumen gas torches on historic Soho timber decks, above trading restaurants, or within the Soho Conservation Area. Fusing IKO Armourplan and Sika membranes with temperature-regulated Leister hot-air welding machines eliminates hot-works fire risks while forming a molecular seam stronger than the membrane itself.
PARAPET DRAINAGE, WESTMINSTER LOGISTICS & 20-YEAR GUARANTEES
As shown in our rooftop photography, flat roofs enclosed by London stock brick and rendered parapet walls rely on accurate drainage falls to prevent rainwater pooling around skylight kerbs and plant units. Our carpenters install graduated timber firrings beneath 18mm BS 1088 marine plywood decking so water clears rapidly into perimeter outlets and internal downpipes. Every full flat roof replacement we complete in W1 is carried out by our own vetted, directly employed technicians—managing all Westminster City Council pavement licences, Shaftesbury Estate and Soho Estates approvals, and early-morning delivery windows in-house—and backed by a 10-year insurance-backed workmanship guarantee alongside 20-year manufacturer warranties.

Frequently Asked Questions: Flat Roofer Soho W1
Can you cut new openings for electric skylights or a plant access hatch into an existing Soho 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 over rear lightwells, or hinged polycarbonate access hatches, handling all Westminster Building Control Part A and Part L sign-offs.
How do you replace a flat roof on a narrow Soho street without disrupting trading businesses below?
Working on pedestrianised or high-footfall streets like Carnaby Street, Beak Street, and Old Compton Street requires tight logistical planning. We arrange Westminster City Council out-of-hours material deliveries, pavement licences, and alarmed scaffolding, using odour-free cold liquids and quiet hot-air welded IKO Armourplan single-ply so ground-floor restaurants, shops, and media offices continue operating without interruption.
