What do commercial flat roofs in Wellingborough need?
Safety planning matters on commercial sites in Wellingborough. Every job is planned under CDM, with a method statement, edge protection and covers over rooflights and fragile areas. If asbestos is found, a licensed specialist surveys and removes it before our work starts, so nobody is put at risk.
In a large town like Wellingborough, flat roofs are commonly found on terraced streets with flat-roofed rear kitchens and bathrooms or newer estates where the first extension roofs are now being replaced. The East Midlands is drier than the west of Britain, so most flat roofs here fail through age, UV and poor detailing at upstands rather than sheer rainfall.
How much does a commercial flat roof cost in Wellingborough?
For Wellingborough we use East Midlands rates: £12,950–£21,350 is the guide for a 100 m² commercial roof in single-ply with insulation, VAT included. The fixed price comes after a free survey for new and replacement roofs.

| Condition survey and leak investigation | £150–£290 |

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.

£12,950–£21,350 for a 100 m² commercial roof in single-ply with insulation, at East Midlands guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Do you work on school roofs?
Yes, where the school or its managing body appoints its own contractor. If your procurement rules require a framework contractor, check that before asking us to quote.
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.
