What do block and HMO roofs in Stevenage need?
Fire performance matters near boundaries and on occupied buildings in Stevenage. 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.
Stevenage's flat roofs are mostly on low-rise post-war blocks of flats, with plenty on shops with flat-roofed rear stores below flats too. 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 Stevenage?
Guide price in Stevenage: £16,350–£28,550 for a 150 m² block-of-flats roof in felt with insulation and scaffold, including VAT at East of England 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 | £16,350–£28,550 |
| Commercial roof (100 m²), single-ply + insulation | £13,900–£22,850 |
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?
- Free survey and fixed, itemised written quote
- Building control and insulation upgrades handled where needed
- 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.
