What do commercial flat roofs in Chichester need?

Safety planning matters on commercial sites in Chichester. 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 town like Chichester, flat roofs are commonly found on low-rise post-war blocks of flats or 1930s semis with flat-roofed garages and kitchen extensions. 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 Chichester?

For Chichester 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.

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
  • Single-ply, built-up felt, liquid-applied and mastic asphalt systems
  • Programme planned around trading hours, deliveries and site rules
  • Warm-roof insulation upgrades and building control where needed

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.

Who checks building regulations for a flat roof in Chichester?

Where the work needs approval it goes to Chichester District Council building control, or a registered building control approver. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.

How much does a commercial flat roof cost in Chichester?

£14,550–£23,950 for a 100 m² commercial roof in single-ply with insulation, at South East guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Can you re-roof while our premises stay open?

Usually, yes. We phase the work so each section is watertight before the team leaves site, keep entrances and fire exits clear, and agree working hours and deliveries with you first.

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.
