What do block and HMO roofs in Norwich need?
Service charge budgets for blocks in Norwich do not always stretch to a whole roof at once. We can phase a re-roof over more than one budget year, pricing each phase separately in writing and keeping every section watertight in between, so the building stays protected while the cost is spread.
In a large town like Norwich, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or terraced streets with flat-roofed rear kitchens and bathrooms. 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 Norwich?
At East of England guide rates, a 150 m² block-of-flats roof in felt with insulation and scaffold comes to £16,350–£28,550 including VAT. 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 |
Which roofing systems last longest on a block of flats?
Mastic asphalt, EPDM, single-ply and high-performance built-up felt all give long service lives on block roofs; the right choice depends on the deck, how the roof is used, the details and the whole-life cost.
- Mastic asphalt: 30–60 years with maintenance, common on concrete-decked blocks and walkways. See mastic asphalt roofing.
- EPDM: 25–50 years, laid in large sheets with few joins.
- Single-ply: 25–35+ years, quick to lay on larger roofs, with welded laps. See single-ply roofing.
- Built-up felt: 15–25 years for modern torch-on systems and longer for high-performance systems, robust where maintenance teams walk the roof.
- Liquid-applied: 10–25+ years by product, useful as an overlay on a sound roof with complex details.
The cheapest roof today is not always the cheapest over the life of the building. A longer-life system, with tapered insulation to cure ponding, can mean fewer reactive repairs and fewer rounds of consultation. These lives are indicative and assume good specification and regular maintenance.

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.
