What do commercial flat roofs in Oldham need?
We are flat roof specialists, so a commercial roof in Oldham 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.
Around Oldham, flat roofs are common on lock-up garage blocks on estates and on newer estates where the first extension roofs are now being replaced. 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.

Can you work around our trading hours and site rules?
Yes. Most commercial roofs can be replaced while the building stays open, and we agree the programme with you before any work starts.
That normally means set working hours, delivery and skip positions that keep entrances and fire exits clear, and phasing the roof so each section is watertight before the team leaves site. Noisy tasks such as strip-out can be timed for quieter periods, and early starts or weekend working can be arranged where your site allows. We tell you in advance which areas below the roof may be affected, so stock and equipment can be protected or moved.
Where torch-on felt is specified, the team works under your hot works permit system, with a fire watch after the torch is put away. If your site does not allow naked flames, we specify a cold-applied, self-adhesive or other flame-free system instead. Tenants, alarm companies and mechanical contractors are coordinated through one named contact.

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.

Do you need a hot works permit?
Only if torch-on felt or other naked-flame work is used, in which case the team works under your permit system with a fire watch afterwards. Where hot works are not allowed, we specify a flame-free system such as a cold-applied membrane.
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.
