What do block and HMO roofs in Caldicot need?
Fire performance matters near boundaries and on occupied buildings in Caldicot. 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 Caldicot, flat roofs are common on low-rise post-war blocks of flats and on 1930s semis with flat-roofed garages and kitchen extensions. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.
How much does a block or HMO roof cost in Caldicot?
At Wales guide rates, a 150 m² block-of-flats roof in felt with insulation and scaffold comes to £14,300–£25,000 including VAT. 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 | £14,300–£25,000 |
| Commercial roof (100 m²), single-ply + insulation | £12,150–£20,050 |
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
- Quotes laid out to support leaseholder consultation
- Building control and insulation upgrades handled where needed
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
Building regulations in Wales
The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

Flats, HMOs and block roofs in Caldicot: questions
Do you cover Caldicot?

Who checks building regulations for a flat roof in Caldicot?
Where the work needs approval it goes to Monmouthshire County 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 Caldicot?
£14,300–£25,000 for a 150 m² block-of-flats roof in felt with insulation and scaffold, at Wales 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 residents need to move out during a re-roof?
No. Block roofs are normally replaced with residents in place, and if we need to check a ceiling inside a top-floor flat, access is arranged through the agent or landlord.
