What do block and HMO roofs in Worthing need?
A block roof in Worthing is a long-term asset, so we talk about whole-life cost as well as the price today. A longer-life system with corrected falls can mean fewer reactive repairs and fewer rounds of consultation over the years, and the survey explains the options in plain terms.
Worthing's flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches, with plenty on bungalows with flat-roofed side extensions and dormers too. 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 Worthing?
Guide price in Worthing: £17,100–£29,900 for a 150 m² block-of-flats roof in felt with insulation and scaffold, including VAT at South East rates. 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 do you manage access and residents during the work?
We agree an access and communication plan with the agent or freeholder before the scaffold goes up, so residents know what is happening and when.
That usually covers notices in the common parts and letters to each flat, scaffold and skip positions, keeping entrances, escape routes and bin stores clear, working hours, securing the scaffold out of hours, and a named contact for questions. If we need to look at a ceiling inside a top-floor flat, we arrange access through the agent or landlord.
Occupied blocks are re-roofed in phases, with each section watertight before the team leaves site, which also lets a larger roof be spread over more than one service charge year. Hot works near windows, vents and escape routes are tightly controlled, or avoided altogether with cold-applied systems.
What's included?
- Resident notices, access planning and phased work
- Long-life systems: mastic asphalt, EPDM, single-ply and built-up felt
- Building control and insulation upgrades handled where needed
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
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 Worthing: questions
Do you cover Worthing?
Yes. Worthing is part of our West Sussex coverage, including postcode districts BN11, BN12, BN13, BN14. 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 Worthing?
Where the work needs approval it goes to Worthing Borough 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 Worthing?
£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.
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.
