What do block and HMO roofs in Thorne need?

When a roof over heated flats in Thorne 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.

In and around Thorne, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, and on low-rise post-war blocks of flats. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county.

How much does a block or HMO roof cost in Thorne?

For Thorne we use Yorkshire and the Humber 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.

JobGuide 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.

What's included?

  • Long-life systems: mastic asphalt, EPDM, single-ply and built-up felt
  • Written workmanship guarantee, with manufacturer guarantees registered where the system allows
  • Resident notices, access planning and phased work
  • Building control and insulation upgrades handled 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.
