What do commercial flat roofs in Ely need?
We are flat roof specialists, so a commercial roof in Ely gets a system chosen for the job: single-ply for large, simple areas, built-up felt where there is foot traffic and plant, or a liquid overlay where the existing roof is sound. The survey explains the trade-offs in plain terms.
Ely's flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms, with plenty on low-rise post-war blocks of flats too. 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 Ely?
For Ely we use East of England rates: £13,900–£22,850 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.
| 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.
What's included?
- Programme planned around trading hours, deliveries and site rules
- Warm-roof insulation upgrades and building control where needed
- Single-ply, built-up felt, liquid-applied and mastic asphalt systems
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
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 Ely?
£13,900–£22,850 for a 100 m² commercial roof in single-ply with insulation, at East of England 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 the cost be spread over more than one budget year?
Yes. We can price a phased programme with each section shown separately, starting with the most urgent areas, so you can plan the spend while the building stays protected.
