What do commercial flat roofs in Middleton need?
When a roof over heated space in Middleton is replaced, insulation rules usually apply. We design the warm-roof build-up towards the required standard where that is feasible and handle building control where it is needed, so the work is signed off properly and the building is better insulated afterwards.
Middleton's flat roofs are mostly on bungalows with flat-roofed side extensions and dormers, with plenty on 1930s semis with flat-roofed garages and kitchen extensions too. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.

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?
- 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
- 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.

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.
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.
