What do block and HMO roofs in Oldham need?
When a roof over heated flats in Oldham 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 top-floor flats are better insulated.
Around Oldham, flat roofs are common on newer estates where the first extension roofs are now being replaced and on 1930s semis with flat-roofed garages and kitchen extensions. 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 much does a block or HMO roof cost in Oldham?
For Oldham we use North West rates: £14,750–£25,850 is the guide for a 150 m² block-of-flats roof in felt with insulation and scaffold, VAT included. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Block of flats (150 m²), felt + insulation + scaffold | £14,750–£25,850 |
| Commercial roof (100 m²), single-ply + insulation | £12,550–£20,700 |
Do fire and insulation rules affect block roofs?
Yes. Where a roof is close to a boundary, building regulations limit which coverings can be used, and the build-up should carry a suitable external fire classification such as BROOF(t4); in England this is covered by Approved Document B.
BROOF(t4) applies to a tested build-up, so we check that the manufacturer's classification covers the deck, insulation and membrane actually being installed, not just the membrane name. Where the roof crosses a separating or compartment wall, the fire-stopping detail is kept intact.
Re-covering more than half of a roof over heated flats usually triggers the thermal element rules, so the insulation is upgraded towards the renovation U-value where feasible: 0.16 W/m²K for dwellings in England and Wales. We handle building control where it is needed. See building regulations and warm vs cold roofs.

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 Oldham?
Where the work needs approval it goes to Oldham 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 block or HMO roof cost in Oldham?
£14,750–£25,850 for a 150 m² block-of-flats roof in felt with insulation and scaffold, at North West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
What if a top-floor flat is leaking before the roof is replaced?
We can attend for emergency temporary weatherproofing as soon as a team is available, guide £170–£430. That protects the flat while the permanent work is agreed.
Can you quote for more than one roofing system?
Yes. We can price two or more systems on the same scope, for example built-up felt and single-ply, so leaseholders and the freeholder can compare cost against expected service life.
