What do block and HMO roofs in Chertsey need?
A block roof in Chertsey 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.
Around Chertsey, flat roofs are common on bungalows with flat-roofed side extensions and dormers and on 1960s and 1970s link-detached houses with flat-roofed garages and porches. 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 Chertsey?
For Chertsey 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
- Free survey and fixed, itemised written quote
- Resident notices, access planning and phased work
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.
