GLOBE HOUSE CONVERSION & FLAT ROOFING IN MAIDENHEAD SL6
From multi-storey office conversions and commercial headquarters around the town centre, St Cloud Way, and Vanwall Business Park to detached riverside residences in Bray, Fishery Estate, and Cookham (SL6), Maidenhead buildings require resilient, low-maintenance flat roof engineering. On our flagship Maidenhead refurbishment at Globe House pictured here, London Roofing Specialist acted as the appointed flat roofer—stripping the weathered roof covering to install a Part L warm roof assembly and a hot-air welded Sika Sarnafil single-ply membrane alongside one-piece EPDM rubber waterproofing.
Sika Sarnafil Single-Ply, EPDM Rubber & Warm Roof Build-Ups
Whether we are re-roofing a commercial office block near the Elizabeth Line station or waterproofing a domestic kitchen-diner extension along Ray Mill Road, we engineer complete flat roof systems to BS 6229 standards without naked gas flames.
Sika Sarnafil & IKO Polymeric Single-Ply
Hot-air welded thermoplastic membranes offering 40-year BBA-certified longevity, solar reflectance, and total immunity to ponding rainwater.
Vulcanised One-Piece & Fleece-Backed EPDM
Cold-adhered synthetic rubber membranes that stretch up to 300% to absorb seasonal thermal movement on timber and concrete decks.
Part L Tapered & Flat PIR Thermal Insulation
High-compressive Sikatherm PIR insulation boards laid over a continuous vapour control layer to eliminate cold bridging and interstitial condensation.
Cold-Applied Liquid Parapet & Plant Detailing
Fibre-reinforced Sikalastic resins brushed around intricate HVAC stanchions, soil stacks, parapet outlets, and mansard junctions.
SUBSTRATE CARPENTRY, TAPERED FALLS & HEAT-WELDED SEAMS
Prior to laying the new waterproof membranes at Globe House in Maidenhead, our surveyors and roof carpenters carried out a comprehensive structural inspection of the underlying deck. Where flat roofs lack adequate drainage gradients, standing water accelerates membrane fatigue and adds dead-load stress. We install graduated firring strips or tapered insulation schemes to establish a positive 1:40 fall towards the rainwater outlets, screwing down 18mm WBP exterior-grade plywood or mechanically fixing into profiled metal and concrete substrates before fusing every single-ply lap with calibrated hot-air welders.
Zero-Flame Safety & Royal Borough of Windsor and Maidenhead Compliance
We never use naked bitumen gas torches near dry roof timbers, mansard dormers, or occupied commercial premises. Every Sika Sarnafil, EPDM, and liquid system we install across SL6 achieves unrestricted BROOF(t4) fire classification and full Building Control sign-off.
10-YEAR INSURED GUARANTEES & MAIDENHEAD FLAT ROOF SURVEYS
Every commercial roof overhaul, residential conversion, and warm roof replacement we complete in Maidenhead, Taplow, Marlow, and Bray is executed by our directly employed, Sika- and NFRC-accredited operatives.

Can you refurbish a commercial flat roof in Maidenhead without disrupting tenants or office staff?
Yes. As demonstrated during the Globe House conversion in Maidenhead, we erect secure, alarmed perimeter scaffolding, hoist all insulation and membrane rolls externally, and strip and weather-seal the roof in phased daily sections using odourless, flame-free single-ply and EPDM systems so building occupants remain undisturbed.
Which flat roof membrane is best for a large residential extension or garage in SL6?
For domestic extensions, double garages, and pool houses around Maidenhead and Bray, vulcanised EPDM rubber and Sika Sarnafil Lead Grey single-ply are the two leading specifications. Both systems eliminate vulnerable torch-on felt joints, accommodate natural timber movement across wide spans, and deliver a 40-year+ service life with virtually zero maintenance.
