What do commercial flat roofs in Hammersmith and Fulham need?
Owners and agents in Hammersmith and Fulham 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.
In a town like Hammersmith and Fulham, flat roofs are commonly found on Victorian and Edwardian terraces with flat-roofed back additions or 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.

Can you work around our trading hours and site rules?
Yes. Most commercial roofs can be replaced while the building stays open, and we agree the programme with you before any work starts.
That normally means set working hours, delivery and skip positions that keep entrances and fire exits clear, and phasing the roof so each section is watertight before the team leaves site. Noisy tasks such as strip-out can be timed for quieter periods, and early starts or weekend working can be arranged where your site allows. We tell you in advance which areas below the roof may be affected, so stock and equipment can be protected or moved.
Where torch-on felt is specified, the team works under your hot works permit system, with a fire watch after the torch is put away. If your site does not allow naked flames, we specify a cold-applied, self-adhesive or other flame-free system instead. Tenants, alarm companies and mechanical contractors are coordinated through one named contact.
What's included?

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.

How much does a commercial flat roof cost in Hammersmith and Fulham?
£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.
What happens to air conditioning units and other roof plant?
Plant can often stay in place, with the new roof detailed around its supports. Where it has to be isolated and lifted, your mechanical contractor does that while we re-roof beneath it, and we agree the timing at survey stage.
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.
