What do commercial flat roofs in Ealing need?
Owners and agents in Ealing can plan spending with a phased programme: urgent repairs now, then re-roofing section by section over one or more budget years. Each phase is priced separately in writing, and the survey and quote for replacement work are free, with no obligation to go ahead.
Around Ealing, flat roofs are common on Victorian and Edwardian terraces with flat-roofed back additions and on mansard and dormer loft conversions. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.

How do you handle CDM, roof access and fragile surfaces?
Every job is planned under the Construction (Design and Management) Regulations 2015, or CDM (NI) 2016 in Northern Ireland, with a construction phase plan and a method statement for the roof.
As a commercial client you have duties under CDM too, including passing on information about the building, such as drawings, details of previous roof work and the asbestos register. Buildings put up before 2000 can contain asbestos, so we ask for the register or a refurbishment survey before pricing a strip-out. If asbestos is found, a licensed specialist surveys and removes it before we start.
Roofs and rooflights are treated as fragile until a competent person confirms otherwise. Edge protection goes up on every job, rooflights and fragile sheets are covered or fenced off, and we agree safe access before work starts: scaffold, a tower, a powered access platform or a fixed access point where one is suitable.
What's included?
- CDM planning, edge protection and fragile-surface controls on every job
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
- Programme planned around trading hours, deliveries and site rules
- Free survey and fixed written quote for replacement and new roofs
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

Commercial flat roofing in Ealing: questions

Yes. Ealing is part of our London coverage, including postcode districts W5, W13, W7, W3, TW8, UB6 and 1 more. Surveys and roofs are carried out by vetted roofing teams working under S&K Property Investments and Improvement Ltd.
Who checks building regulations for a flat roof in Ealing?
Where the work needs approval it goes to London Borough of Ealing building control, or a registered building control approver. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.
How much does a commercial flat roof cost in Ealing?
£15,900–£26,150 for a 100 m² commercial roof in single-ply with insulation, at London guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Who deals with building control on a commercial re-roof?
We do, where the work needs approval. Replacing more than half of a roof over heated space usually means upgrading the insulation towards the renovation U-value where feasible, which is 0.18 W/m²K for non-domestic buildings in England.
Can our existing roof be overlaid instead of stripped?
Often, if the survey shows the existing covering is sound, dry and firmly bonded. Wet insulation, a soft deck or several old layers mean a strip-out is the better long-term answer.
