What do block and HMO roofs in Brent need?
Roof works on a block in Brent affect many households at once. We agree notices, scaffold positions, working hours and a named contact with the agent or freeholder before we start, so residents know what is happening, when it will happen and who to ask if they have a question.
Brent's flat roofs are mostly on shops with flat-roofed stores below flats above, with plenty on Victorian and Edwardian terraces with flat-roofed back additions too. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.
How much does a block or HMO roof cost in Brent?
Guide price in Brent: £18,650–£32,650 for a 150 m² block-of-flats roof in felt with insulation and scaffold, including VAT at London 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 | £18,650–£32,650 |
| Commercial roof (100 m²), single-ply + insulation | £15,900–£26,150 |
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.

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 Brent: questions
Do you cover Brent?
Yes. Brent is part of our London coverage, including postcode districts HA9, HA0, NW10, NW9, NW2, NW4. 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 Brent?
Where the work needs approval it goes to London Borough of Brent 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 Brent?
£18,650–£32,650 for a 150 m² block-of-flats roof in felt with insulation and scaffold, at London 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 £220–£540. That protects the flat while the permanent work is agreed.
