What do commercial flat roofs in Dunstable need?
Safety planning matters on commercial sites in Dunstable. 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 Dunstable, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or bungalows with flat-roofed side extensions and dormers. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.
How much does a commercial flat roof cost in Dunstable?
Guide price in Dunstable: £13,900–£22,850 for a 100 m² commercial roof in single-ply with insulation, including VAT at East of England rates. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Commercial roof (100 m²), single-ply + insulation | £13,900–£22,850 |
| Condition survey and leak investigation | £160–£320 |
| Block of flats (150 m²), felt + insulation + scaffold | £16,350–£28,550 |
Do you offer condition surveys and phased budgets?
Yes. A condition survey with a written report is a paid service, guide £160–£320 for a typical single roof, with larger or multi-roof sites priced before we attend. A survey and quote for replacement work is free.
The report covers the covering, upstands, outlets, edges and rooflights, signs of ponding or wet insulation, and what needs doing now, soon and later. You can then plan a phased programme: urgent repairs first, then re-roofing in sections over one or more budget years, with each phase priced separately in your written quote.
Re-covering more than half of a roof over heated space usually triggers the thermal element rules, so the insulation is upgraded towards the renovation U-value where feasible; in England the non-domestic target is 0.18 W/m²K. We handle building control where it is needed. See building regulations and flat roof surveys.

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.
