Which flat roofs are common in Blaenau Gwent?

Flat roofs in Blaenau Gwent sit on low-rise post-war blocks of flats, lock-up garage blocks on estates and 1960s and 1970s link-detached houses with flat-roofed garages and porches. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof. Approximate 1991–2020 regional averages based on Met Office data.

Building regulations in Wales

Welsh guidance is that most re-roofing needs building control approval, so it's worth checking whenever more than a quarter of a roof is replaced or repaired. Renovated roofs are upgraded to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K under the Welsh Approved Document L. In Blaenau Gwent the application goes to Blaenau Gwent County Borough Council. More on the rules.

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.

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.

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.

Can you quote for more than one roofing system?

Yes. We can price two or more systems on the same scope, for example built-up felt and single-ply, so leaseholders and the freeholder can compare cost against expected service life.

Do you work for HMO landlords?

Yes. We replace and repair flat roofs on HMOs and converted flats, arrange access with tenants through the landlord or agent, and keep escape routes and entrances clear while we work.
