What do block and HMO roofs in Gelligaer need?
A block roof in Gelligaer 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.
Gelligaer's flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches, with plenty on 1930s semis with flat-roofed garages and kitchen extensions too. 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 Gelligaer?
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 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
- Resident notices, access planning and phased work
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
- Building control and insulation upgrades handled where needed
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.
