What do commercial flat roofs in Gravesend need?
Safety planning matters on commercial sites in Gravesend. 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.
Around Gravesend, flat roofs are common on lock-up garage blocks on estates and on newer estates where the first extension roofs are now being replaced. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a commercial flat roof cost in Gravesend?
For Gravesend we use South East rates: £14,550–£23,950 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 | £14,550–£23,950 |
| Condition survey and leak investigation | £170–£330 |
| Block of flats (150 m²), felt + insulation + scaffold | £17,100–£29,900 |
Do you offer condition surveys and phased budgets?
Yes. A condition survey with a written report is a paid service, guide £170–£330 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?
- Single-ply, built-up felt, liquid-applied and mastic asphalt systems
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
- Free survey and fixed written quote for replacement and new roofs
- Programme planned around trading hours, deliveries and site rules
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.
