What do block and HMO roofs in Bishop's Stortford need?
When a roof over heated flats in Bishop's Stortford is replaced, insulation rules usually apply. We design the warm-roof build-up towards the required standard where that is feasible and handle building control where it is needed, so the work is signed off properly and the top-floor flats are better insulated.
In a town like Bishop's Stortford, flat roofs are commonly found on shops with flat-roofed rear stores below flats or 1960s and 1970s link-detached houses with flat-roofed garages and porches. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.
How much does a block or HMO roof cost in Bishop's Stortford?
For Bishop's Stortford we use East of England rates: £16,350–£28,550 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.

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?
- Free survey and fixed, itemised written quote
- Quotes laid out to support leaseholder consultation
- Resident notices, access planning and phased work
- 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.
