What do block and HMO roofs in Bognor Regis need?
Fire performance matters near boundaries and on occupied buildings in Bognor Regis. 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 Bognor Regis, flat roofs are common on 1960s and 1970s link-detached houses with flat-roofed garages and porches and on lock-up garage blocks on estates. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a block or HMO roof cost in Bognor Regis?
For Bognor Regis we use South East rates: £17,100–£29,900 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 | £17,100–£29,900 |
| Commercial roof (100 m²), single-ply + insulation | £14,550–£23,950 |
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?
- Building control and insulation upgrades handled where needed
- Long-life systems: mastic asphalt, EPDM, single-ply and built-up felt
- Quotes laid out to support leaseholder consultation
- 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 Bognor Regis: questions
Do you cover Bognor Regis?
Yes. Bognor Regis is part of our West Sussex coverage, including postcode districts PO21. Surveys and roofs are carried out by vetted roofing teams working under S&K Property Investments and Improvement Ltd.
Who checks building regulations for a flat roof in Bognor Regis?
Where the work needs approval it goes to Arun District 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 Bognor Regis?
£17,100–£29,900 for a 150 m² block-of-flats roof in felt with insulation and scaffold, at South East 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.
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 £200–£500. That protects the flat while the permanent work is agreed.
