What do commercial flat roofs in Thatcham need?
Businesses in Thatcham need a roofing contractor who arrives with a plan, not just a price. We put the system, build-up, phasing, access and payment terms in a fixed written quote, and keep each section of the roof watertight before the team leaves site, so trading is not put at risk.
In a town like Thatcham, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or lock-up garage blocks on estates. 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 Thatcham?
At South East guide rates, a 100 m² commercial roof in single-ply with insulation comes to £14,550–£23,950 including VAT. 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?
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
- Warm-roof insulation upgrades and building control where needed
- Single-ply, built-up felt, liquid-applied and mastic asphalt systems
- CDM planning, edge protection and fragile-surface controls on every job
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 Thatcham?
£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 our existing roof be overlaid instead of stripped?
Often, if the survey shows the existing covering is sound, dry and firmly bonded. Wet insulation, a soft deck or several old layers mean a strip-out is the better long-term answer.
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.
