ENGINEERED FLAT ROOF SYSTEMS ACROSS FELTHAM TW13 & TW14
Spanning the commercial warehouses, air-freight logistics hubs, and trade units around North Feltham Trading Estate, Central Way, and Clockhouse Lane (TW14) to the 1930s rear kitchen-diner extensions, side garages, and flat-roofed chalet dormers across Lower Feltham, Hanworth, and East Bedfont (TW13 and TW14), flat roofs in the London Borough of Hounslow endure constant Heathrow southern-runway acoustic vibrations, thermal cycling, and heavy winter downpours. When ageing mineral felt blisters along lap joints or waterlogged chipboard decking sags beneath standing puddles, rainwater tracks directly into ceiling voids below. Operating as an NFRC-accredited flat roofer in Feltham, London Roofing Specialist deploys directly employed waterproofing technicians across TW13 and TW14 to strip perished coverings, renew structural timber decks, and install Sika Sarnafil single-ply, vulcanised EPDM rubber, and cold-applied liquid polyurethane systems.
Vapour Control, OSB3 Decking & Part L Warm Roof Insulation
Every flat roof replacement in Feltham starts with a structural load inspection of the existing C24 timber joists, concrete slabs, or profiled metal decks. We strip sodden boards, install 18mm exterior-grade OSB3 or BS 1088 marine plywood over graduated timber firring strips to guarantee a positive 1:40 drainage fall, and mechanically fix 120mm to 150mm foil-faced PIR insulation boards above a continuous vapour control layer to satisfy Hounslow Building Control Part L U-value mandates.
TAILORED FLAT ROOF RENEWALS IN FELTHAM, BEDFONT & HANWORTH
Our Feltham flat roofing operatives refurbish split bitumen felt, leaking rear extension decks, detached garage roofs, and commercial parapet gutters across TW13 and TW14. We finish every perimeter with custom-formed Code 4 and Code 5 milled lead flashing aprons and mechanical drip trims to stop wind-driven rain creeping behind brickwork.
Sika Sarnafil & Wolfin Polymeric Single-Ply
Hot-air welded thermoplastic membranes delivering crisp architectural profiles, solar reflectivity, and BBA-certified 40-year durability for extensions, schools, and commercial units.
Seamless One-Piece EPDM Rubber Systems
Cold-adhered synthetic rubber membranes cut to fit single and double garages, garden annexes, and bay window roofs across Feltham and Bedfont without vulnerable field joints.
Debotec Three-Layer Torch-On & Elastomeric Felt
Reinforced SBS-modified multi-layer felt systems with mineral cap sheets engineered for high foot-traffic durability on apartment blocks and commercial parades along Feltham High Street.
Cold-Applied Sikalastic Liquid Waterproofing
Rapid-curing, fibre-reinforced polyurethane resins brushed seamlessly around complex skylight kerbs, HVAC plant plinths, and balcony thresholds.
Substrate Integrity & Interstitial Condensation Prevention
Replacing decayed chipboard or delaminated plywood with structural exterior-grade timber decking before bonding the vapour barrier stops warm household moisture migrating into the cold roof void, preventing winter condensation and timber rot for decades.
CERTIFIED WATERPROOFING & FLAME-FREE INSTALLATION IN TW13 & TW14
Fitting modern single-ply and liquid flat roof membranes near the Heathrow perimeter requires calibrated hot-air welding equipment and strict site safety compliance. London Roofing Specialist deploys manufacturer-certified installers skilled in flame-free Leister seam welding, lead counter-flashing, and parapet coping weatherproofing so there is zero naked-flame risk to your home or commercial premises.
Comprehensive 10-Year Insurance-Backed Guarantees
We never rely on temporary mastic or surface patch repairs. By replacing rotten timber noggins, repointing brick parapets, and installing deep-flow rainwater outlets and scuppers, we provide Feltham property owners with a permanent, storm-proof barrier backed by a 10-year insurance-backed workmanship guarantee.

How do you tackle flat roof replacements on Feltham homes and extensions?
We start with a core and drainage survey to check joist condition, fall angles, and outlet capacity. Our team strips away perished felt or fibreglass, secures new 18mm OSB3 structural deck boards with tapered firrings and rigid PIR thermal insulation, and hot-air welds or cold-bonds a Sika single-ply, EPDM, or multi-layer felt membrane backed by a 10-year guarantee.
Do I need Hounslow Council Building Control approval when replacing a flat roof in TW13 or TW14?
When replacing more than 50 per cent of a flat roof covering over a heated habitable room—such as a kitchen extension, utility room, or loft dormer—Building Regulations Part L require upgrading the thermal insulation to current U-value standards. Unheated detached garages are exempt from thermal upgrades, and we supply all photographic evidence and specification certificates needed for Hounslow Building Control sign-off.
