What do block and HMO roofs in Carmarthen need?
A block roof in Carmarthen 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.
In a town like Carmarthen, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or lock-up garage blocks on estates. 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.
How much does a block or HMO roof cost in Carmarthen?
At Wales guide rates, a 150 m² block-of-flats roof in felt with insulation and scaffold comes to £14,300–£25,000 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 | £14,300–£25,000 |
| Commercial roof (100 m²), single-ply + insulation | £12,150–£20,050 |
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?
- Building control and insulation upgrades handled where needed
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
- Quotes laid out to support leaseholder consultation
- Resident notices, access planning and phased work
Building regulations in Wales
The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

£14,300–£25,000 for a 150 m² block-of-flats roof in felt with insulation and scaffold, at Wales guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
What if a top-floor flat is leaking before the roof is replaced?
