What do block and HMO roofs in Doncaster need?
Fire performance matters near boundaries and on occupied buildings in Doncaster. We check the external fire classification of the whole roof build-up, not just the membrane, control or avoid hot works near escape routes and windows, and keep fire-stopping details intact where the roof crosses a separating wall.
Around Doncaster, flat roofs are common on 1930s semis with flat-roofed garages and kitchen extensions 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.

Guide price in Doncaster: £14,750–£25,850 for a 150 m² block-of-flats roof in felt with insulation and scaffold, including VAT at Yorkshire and the Humber rates. The fixed price comes after a free survey for new and replacement roofs.

How does Section 20 consultation affect roof works?
In England and Wales, if leaseholders pay for roof works through the service charge and any one leaseholder's share will be over the statutory threshold, the freeholder or managing agent must consult them under Section 20 of the Landlord and Tenant Act 1985 before the work is contracted.
The consultation is run by the freeholder or agent, not by us. It usually involves a notice of intention and then estimates shared with leaseholders, each stage with time for comments, and missing a step can limit what can be recovered through the service charge. Take advice from your agent or a specialist adviser if you are unsure; we don't give legal advice.
What we provide is an itemised written quote that is easy to share and compare: system and build-up, roof area, scaffold and access, insulation, outlets, upstands and trims, waste disposal, provisional sums for hidden defects such as deck repairs, and VAT shown clearly. We can price more than one system on the same scope, so leaseholders are comparing like with like.
What's included?
- Resident notices, access planning and phased work
- Building control and insulation upgrades handled where needed
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
- Free survey and fixed, itemised written quote
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.

Flats, HMOs and block roofs in Doncaster: questions

Who checks building regulations for a flat roof in Doncaster?
Where the work needs approval it goes to City of Doncaster 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 Doncaster?
£14,750–£25,850 for a 150 m² block-of-flats roof in felt with insulation and scaffold, at Yorkshire and the Humber guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Does a block roof replacement need building control?
Usually, yes. Re-covering more than half of a roof over heated flats normally triggers the thermal element rules, which bring insulation and approval requirements, and we handle building control or building standards where it is needed.
Do you work for HMO landlords?
Yes. We replace and repair flat roofs on HMOs and converted flats, arrange access with tenants through the landlord or agent, and keep escape routes and entrances clear while we work.
